Turbine Replacement

Historically many high power compressor and pump systems are powered directly by gas or steam turbines. With increased electrification considerable operational efficiency and CO2 reduction can be gained by changing the gas turbine for an electric drive system.

By using high speed motors, the compressor speed can be matched even without gearbox, thus increasing efficiency. By sourcing the power from a renewable source such as wind, solar or hydro, CO2 emissions can be practically eliminated.

Technology made to shape tomorrow’s energy

Hydrogen

As economies decarbonize and companies look for ways to lower the climate impact of their processes, hydrogen offers a tremendous opportunity. Hydrogen will play a key role to decarbonize the transportation, energy and industry sector with modular plants and infrastructure.

With proven technologies set to become even more efficient, accompanied by additional benefits through sector coupling, hydrogen can help companies, industries and economies achieve both commercial and environmental goals.

Siemens Large Drives is well placed to provide holistic, clean and safe solutions for the emerging hydrogen economy, by offering various power conversion technologies as products or solutions along the hydrogen supply chain from production to distribution.

Hydrogen Production

Modularization of hydrogen plants allows scaling-up and driving down cost.
Siemens Large Drives’ electrification systems, particularly rectifier products and ehouse solutions perfectly support the scaling-up of high-power electrolyzer architectures in large scale hydrogen plants.

Hydrogen Distribution

An essential component of the hydrogen value chain is compression. It is needed to move, store, and use hydrogen. Today there are two primary compression methods possible: dynamic (turbo) compressors and positive displacement (recips). Both get powered either by Siemens Large Drives proven high speed motors and drives ideal for large volume flows or alternatively by VSD-driven high torque motors perfectly fitted for large pressure ratios. Both are based on leading edge designs and high-tech suited to deal with the element H2 and its low molecular weight.

Hydrogen Industrial Partnerships

To make the vitally needed transfer into the emerging H2 economy possible, organizations require partners with many years of experience across the entire hydrogen value chain collaborating on challenges and shortened timeline.

Siemens Large Drives Partners receive scalable access to our design teams, new technologies, co-development, value engineering and joint design-to-cost.

Meaning that our portfolio and its application know-how is well-suited to help you to grow and grow together in this emerging economy.

Carbon Capture, Utilization and Storage (CCUS) and Carbon Capture and Storage (CCS)

Carbon Capture, Utilization and Storage (CCUS) and Carbon Capture and Storage (CCS) are essentially climate mitigation tools adopted by various governments and organizations to achieve carbon neutral or 'net zero' status. In CCUS process, carbon is captured from the exhaust of the industrial plants using various processes. The captured CO2 is then either transported by pipeline or directly stored deep underground.

We have perfectly suitable drives product portfolio which can be used as high availability starting or continuous converters. These converters provide near sinusoidal waveforms at line side and motor side which is a great advantage for installation on grids in cities.

Induced Draft (ID) Fans

ID fans work with the forced draft fan’s integrated forward bias signal to maintain a boiler in balanced draft. Introduction of environmental control equipment has caused ID fan size requirements to increase dramatically – by double or triple in many cases – due to the increased pressure required to support this equipment and the reduced fan operating temperatures. As the ID fan maintains a pressure balance (balanced draft), the increased fan size becomes a significant concern in terms of boiler implosion impact, especially in the case of a Main Fuel Trip (MFT). VFDs reduce the possibility of implosion significantly, as speed control provides the ability to quickly adjust pressure between the fans and maintain the proper balance.

Forced Draft (FD) Fans

FD fans provide air to support combustion in the boiler. In this application, air flow is approximately linear with power. FD fan power and capacity are inversely impacted by the ambient supply air; therefore, FD fans can limit plant power on the hottest days and can be difficult to control on the coldest. VFDs can easily adjust for these conditions and produce constant power and consistent throughput.

Primary Air (PA) Fans

PA fans provide air to the mills to move the pulverized coal into the boiler. PA fans are commonly designed for very high temperatures but normally operate at considerably lower temperatures. Accuracy of PA fan flow control impacts the effective transfer of the pulverized coal to the boiler, which impacts burn quality, stack rate and excess air.

Boiler Feed Water Pumps (BFPs)

The boiler feed water pumps are used for feeding large volumes of water to the boiler and can represent some of the largest loads in a power station. BFPs play a critical role in boiler operation – any issue in their operation can result in the complete shut down of the power station. Where BFPs are turbine driven, a large benefit can be available to the plant owner in terms of installed cost, life cycle maintenance costs, range of control, operating costs and method of system control. VFDs offer the most precise and responsive method for regulating the BFP flow. Speed control adds an important level of safety and also limits exposure to potential shut downs.

Condenser Circulating Water Pumps (CWPs)

CWPs have a significant impact on steam generator efficiency. Operating at the desired condenser vacuum provides maximum efficiency of the turbine and maximum electric power production. VFDs are the perfect solution for maintaining the desired condenser vacuum even in highly dynamic conditions. CWPs are commonly uncontrolled putting condenser efficiency and performance at the mercy of the ambient temperature. By applying a VFD to a CWP, the flow rate through the condenser can be changed to maintain optimal back pressure or vacuum.

Another benefit of using a VFD on a CWP is decreased environmental impact. Since open-loop CCW systems draw in massive amounts of water directly from reservoirs. However with VFDs, a slow ramp rate is used – greatly reducing potential harm to aquatic life, disturb inlets and impact traveling screen performance.

Static Frequency Converter

Where energy needs to be transferred between two independent power grids (50 Hz to 60 Hz) a grid VFD coupling is required. Grid couplings can either be designed for a uni- or bi-directional power flow.
A typical application for a unidirectional grid coupling is an onshore power supply for ships while they are in a port. Usually ships operate at 60 Hz, while most countries use 50 Hz grids. The grid coupling will allow the ship to source power from shore avoiding diesel generators running thus reducing emissions.
Another example are offshore platforms, where subsea cables connect the platform to green onshore power instead of power generation with gas turbines on the platform.
This allows a drastic reduction of the CO2 footprint. If there is a difference in frequency from shore to the platform then frequency converters can connect the two systems together. The Static Frequency Converter can also be used to correct power factor.

Water Injection Pump

When the reservoir pressure falls it is necessary to implement enhanced recovery techniques to bring the oil and gas to the surface. Water can be injected into the reservoir to boost the pressure, allowing for continued production and increased reservoir production lifetime and recoverable reserves.

Electric variable speed drives are used to vary the pump flow over time in order to optimise operational efficiency. Our electric drives provide the highest customer availability with their unique cell bypass system combined with excellent efficiency and compact footprint.

Gas Lift Compressors

is difficult to pump. To reduce viscosity gas is mixed with the oil at the riser inlet of the drilled hole to allow it to flow or be pumped up the well, at the top of the well the gas and oil are seperated and the gas re-compressed then re-circulated down the well to be remixed with more oil.

Electric variable speed drives are used to vary the compressor head and flow over time to compensate for the varying viscosity of oil over the lifetime of the production of oil. CO2 is kept to a minimum using electrical drives compared to mechanical turbines.

Gas lift compressors range from 1–20 MW, the SINAMICS PERFECT HARMONY GH150 and SINAMICS PERFECT HARMONY GH180 are perfectly designed as the driver for this application.

Electrical Submersible Pumps

Enhanced oil recovery can also be achieved by deploying a pump directly into the oil reservoir to pump oil to the surface allowing for continued production and increased reservoir production lifetime and recoverable reserves. The pump has to be designed to fit down the drilled hole meaning the pump and motor outer diameter is in the range of 10-25 cm. Many stages of motors and pumps are connected together to achieve the required power and can be over 8 meters in length. Designing such narrow motors and pumps requires challenges and compromises, for example the winding insulation is less than a normal motor making it susceptible to over voltage spiking damage.  

As the cable length from the drives can be very long the motor is subjected to transmission line effect that can result in winding damage, the SINAMICS PERFECT HARMONY GH180 have very sinusoidal waveforms and can be used in cable lengths of over 2 km without cable filters.

Multiphase Pump

Offshore a multi-phase pump can be deploying on the ocean floor to boost the flow of oil and gas. As its name suggests a multi-phase pump is part pump part compressor allowing it to boost the flow of both liquids and gasses.

Electric variable speed drives are used to vary the pump flow over time to improve production over the lifetime of the reservoir due to declining reservoir pressure and oil from very remote fields, references include powering multi-phase pumps over 20 km from the production facility.

Our electric drives provide the highest customer availability with their unique cell bypass system and have a very compact footprint. As the cable length from the drives can be very long the motor is subjected to transmission line effect that can result in winding damage, the SINAMICS PERFECT HARMONY GH180 have very sinusoidal waveforms and can be used in cable lengths of over 2 km.

Export Pump

Once oil is recovered to the surface on an offshore production facility it can be stored for later offloading onto a tanker or exported down a subsea pipeline to be connected into onshore pipleline networks or refinery.
The export pump is normally a centrifugal design for high flow.
Electric variable speed drives are used to vary the pump flow over time to minimise motor losses as flow can vary from year to year. Our electric drives provide the highest customer availability with their unique cell bypass system combined with excellent efficiency and compact footprint. CO2 is kept to a minimum using electrical drives compared to mechanical turbines.

Export Compressor

Once gas is recovered to the surface on an offshore production facility it is exported down a subsea pipeline to be connected into onshore pipleline networks or processing facility.

The export compressor is normally a centrifugal type for high pressure and flow.

Electric variable speed drives are used to vary the compressor flow over time to minimise motor losses as flow can vary from year to year. Our electric drives comply with local harmonic codes and are suitable for unmanned locations.

Export compressors range from 5-40 MW, the SINAMICS PERFECT HARMONY GH150 and SINAMICS PERFECT HARMONY GH180 are perfectly designed as the driver for this application.

LNG Refrigeration Compressor

Historically refrigeration compressors are powered by gas turbines. These turbines are sometimes connected to starter motors powered by variable speed drives to allow for a controlled soft start. Some trains also use the motor to provide additional power if the turbines output is limited due to high ambient temperature.

Recently there is a move to all electric eLNG. In this case only an electric drive system powers the compressor. Benefits include high operational efficiency and thus reduced COemissions. Further CO2 reduction can be gained where a renewable power source is available such as hydro-electric.
Further advantages are increased operational flexibility (e.g. restart from settle-out pressure) and longer operating runs due to longer maintenance intervals compared to gas turbines.

Refrigeration compressors range from 30-100 MW, the SINAMICS GL150 and SINAMICS PERFECT HARMONY GH150 is perfectly designed as the driver for this application.

LNG Booster Compressor

The gas pressure at the start if the process is normally sufficiently high from the extraction reservoir pressure, however this natural pressure will decrease over time and at some point will need to be boosted.

Connecting a booster centrifugal compressor at the inlet of to the LNG process will allow the liquefaction to continue over the full lifetime of the LNG plant even as the reservoir pressure depletes.

Electric variable speed drives are used to vary the compressor head over time to compensate for the slowly declining reservoir pressure. Our electric drives provide the highest customer availability with their unique cell bypass system combined with excellent efficiency and compact footprint.

End Flash Gas Compressor

At the end of the liquefaction process during de-pressurisation end flash gas is produced, this gas can be captured and compressed to be used elsewhere or in the process such as for fuel in the gas turbines.

Electric variable speed drives are used to vary the compressor flow to keep the process at optimum efficiency. Our electric drives provide the highest customer availability with their unique cell bypass system combined with excellent efficiency and compact footprint. CO2 is kept to a minimum using electrical drives compared to mechanical turbines.

BOG Compressor

After liquefaction the liquid gas is stored until it can be transported. It is kept in an insulated tank, however over time some of the gas will vaporise, this “boiled” off gas is then re-liquified or used as fuel in the turbines.

This process can power with a fixed speed motor or using electric variable speed drives to vary the compressor flow to reliquefy the gas. Our electric motors are well referenced in this application.

BOG and reliquifaction compressors range from 3-15 MW, the SINAMICS PERFECT HARMONY GH150 is perfectly designed as the driver for this application.

Reliquifaction Compressor

During transportation by ship the liquid gas is in insulated tanks, however over time some of the gas will vaporise, this “boiled” off gas is then re-liquified or used as fuel in the ship propulsion engines. Whilst LNG is an expensive fuel for propulsion it is a much greener than marine grade diesel or oil.

Electric variable speed drives are used to vary the compressor to deliver the correct flow to reliquefy the gas. Our electric drives provide the highest customer availability with their unique cell bypass system combined with excellent efficiency and compact footprint.

Pipeline Pump

Where economically viable transportation by pipeline is a very safe method to deliver oil from the production location to a refinery or consumer.

The export pump is normally a centrifugal design for high flow.

Electric variable speed drives are used to vary the pump flow over time to minimise motor losses as flow can vary from year to year. Our electric drives provide the highest customer availability with their unique cell bypass system combined with excellent efficiency and compact footprint. CO2 is kept to a minimum using electrical drives compared to mechanical turbines.

Pipeline pumps range from 1-25 MW, the SINAMICS PERFECT HARMONY GH150 and SINAMICS PERFECT HARMONY GH180 are perfectly designed as the drives for this application.

Pipeline Compressor

Where economically viable transportation by pipeline is a very safe method to deliver gas from the production location to a processing facility or consumer.

The pipeline compressor is normally a centrifugal type for high pressure and flow.

Electric variable speed drives are used to vary the compressor flow over time to minimise motor losses as flow can vary from year to year. To operate at maximum efficiency high speed motors can also be used to avoid gearbox losses. Our electric drives provide the highest customer availability with their unique cell bypass system combined with excellent efficiency and compact footprint. CO2 is kept to a minimum using electrical drives compared to mechanical turbines.

Export compressors range from 5–40 MW, the SINAMICS PERFECT HARMONY GH150 and SINAMICS PERFECT HARMONY GH180 are perfectly designed as the drives for this application.

Gas Storage Compressor

During transportation of gas it is possible to line pack the pipeline at high pressure to use the gas network as a storage and transportation facility.

Other storage facilities such as old gas reservoirs or underground salt caverns can be used for strategic gas reserves, or for economic models to buy at low cost and sell at high peak points, increasingly CO2 storage is also used to reduce emissions. Most governments and gas companies will store gas during summer months when usage is low and the export the gas at winter to balance high demand periods.  

Electric variable speed drives are used to vary the compressor flow and for fast starting of the process, to operate at maximum efficiency high speed motors can also be used to avoid gearbox losses.

Refineries

Refinery processes require a multitude of different pumps, blowers and compressors which are usually driven by electric motors that typically operate in hazardous areas.
Refineries are highly automated plants that are most economical if they have high operational availability. Due to the high number of different electric motors and drives, handling of spares is a typical challenge, especially if motors from various different suppliers are installed. It can therefore be useful to standardize on a single motor vendor.
Siemens offers a portfolio of hazardous area motors that cover the complete power range. SIMOTICS HV Series H-compact, SIMOTICS HV Modular and SIMOTICS HV High Power are perfectly suited for refinery applications and complemented by a comprehensive range of SINAMICS MV drives.
Furthermore we offer a comprehensive portfolio of digital solutions and services to monitor and manage a large fleet of motors and drives in order to maximize plant availability.
