ICL is ideal for limited spaces industry-wide, including offshore platforms and downstream facilities.• Enhance productivity• High reliability and availability• Low operating cost• Compact and lightweight configuration• High flexibility and wide operating range• Easy installation and low maintenance• Zero emissions and low noise

Proven versatility & reliabilityGE’s Integrated Compressor Line (ICL) is the ideal solution when high efficiency, small footprint and low noise are important. The designs draw on more than 100 years of experience and innovation to deliver proven compression performance in upstream, midstream and downstream clean gas applications.

Instead of a combustion engine, ICL has a high-speed electric motor fully integrated with the compressor in a single sealed casing. It’s a high-efficiency induction motor, proven by 4 million hours of successful operation over 15 years. The rotor is levitated by active magnetic bearings (AMBs) and a precision control system. This eliminates parts contact and wear, lube oil systems and dry gas seals — so there are no fluids to leak or dispose of, and no depressurization required on shutdown.

These units have a much wider operating range than conventional compressors: 35-105% of nominal speed versus the typical 70-105% — and the ICL’s efficiency remains high and stable over the entire range. With 40% lower requested maintenance than conventional compressors, ICL provides exceptional reliability and availability no matter where it’s installed. And it does all this while producing zero emissions.

Offshore• Extended capability for mild/raw gas

- Up to 10% CO2

- Up to 100 ppm H2S

- Water saturated

• New material validated for motor & AMB

• Up to 100 bar suction pressure

In the offshore environment weight and footprint are limited. By saving up to 60% in space and footprint, the ICL can reduce structure cost, avoid additional deck space requirements or limit platform size requirements. The ICL runs on magnetic bearings and avoids dry gas seals. Thus, it does not require oil and does not have continuous gas leakage. This dramatically improves safety by limiting the risk of fire. The ICL package design is simple, widely

accessible and approximately half the size of a conventional compressor. The motor and compressor casing are flanged tightly together so the unit does not require three-point skid mounting. Removing complex auxiliaries such as the lube oil system and dry gas seal panel reduces maintenance downtime, simplifies the noise enclosure design and reduces the amount of noise produced to meet even the toughest regulations.

Innovation & integrationHigh-performance designThe ICL combines our renowned centrifugal compressor technology with an electric motor driver in a single, completely sealed casing that provides an efficient, easily installed and environmentally friendly compression solution for oil and gas applications up to 15 MW.

ICL’s small, lightweight yet powerful package is a result of GE’s unique ability to bring together proven solutions from the oil and gas, aviation and power generation industries. All these technologies have been fully proven in the most demanding conditions, and our well-known compressor technologies have achieved many milestones for the production, transportation and processing sectors of the oil and gas industry.

Centrifugal compressorBoth the multi-stage and the single stage ICL compressor casings are directly flanged onto the motor, avoiding any alignment requirements. The single stage ICL compressor rotor uses a single impeller, directly mounted on the motor shaft through a hirth coupling. The multi-stage ICL compressor rotor features a shaft on which up to 9 impellers can be stacked. The rotor is connected to the motor through a flexible coupling, eliminating the need for complex tuning of the bearing system and simplifying future rewheeling of the compressor. The ICL design incorporates GE Oil & Gas’s latest technological advances, including our high-performance impeller design to deliver the best efficiency, flexibility and operating range.

Pipeline compressionThe single-stage ICL offers a much wider operating range than conventional centrifugal compressors. Our design greatly simplifies the compressor and improves reliability through key features including:

• Overhung single impeller

• Independent motor cooling

• Lateral flange (10 x NEMA)

• Easy lateral access — all preventive maintenance possible without dismantling process piping

• Radial inlet and tangential outlet

• Simplified package with no running auxiliaries

• Standardized GE high speed motor

• Minimal spare parts

• Axial thrust load-control device (patent pending)

• Motor cooling ensured at low pressure ratio

• Flexible IGV option (sealed integrated variable inlet guide vane)

Design pressure ratio• 1.1 to 1.4 (up to 1.55)

• Rated up to 900 lbs

GE high-speed drive system• 4 MW / 5,500 hp, 18,000 rpm

• 6-8.5 MW / 8,000–11,000 hp, 12,000 rpm

• 13 MW / 18,000 hp, 10,500 rpm

Electric motor & driveThe compressor is driven by high-speed motor and high-frequency drive technology from GE Power Conversion. The pressurized, induction motor includes a laminated rotor with a squirrel cage — a design proven by more than 4 million operating hours in industry-wide applications. The drive is highly efficient over a very wide operating range, with the same hardware capable of driving the motor at low speeds and all the way up to 300 Hz.

Active magnetic bearingsWith AMB technology, the rotor is levitated by a control system that precisely regulates the rotor spacing to avoid all parts contact and friction. This eliminates the need for lubricant thereby solving the problem of leak-prone lube oil systems used with conventional bearings. The AMB design maintains rotor levitation during starts, normal operation and stops including emergency shutdowns. Ball bearing back-up allows the machine to stop without damage.

Minimized maintenanceThanks to the AMB system that eliminates parts contact and wear, as well as the absence of lube oil systems and dry gas seal, the ICL maintenance requirements are significantly reduced. As a result, the ICL boasts higher reliability and 40% lower requested maintenance than a conventional compressor.

• No wear parts

• No gearbox

• No lube oil

• No seal systems

Zero emissionsThe ICL is a clean approach to compression. There is no seal leakage from the completely closed case, no depressurization is required on shutdown, and the AMBs require no lubrication, so there are no lubricant leaks and no oil to dispose of.

• No venting on shutdown

• No bearing lube oil

• No seal leakage

Storage & other onshore• Power up to 13 MW/18,000 hp

• Pressure rating up to 1,500 lbs

• Flow up to 45,000 am3/h (26,000 acfm)

• Multi-stage in-line or back-to-back

• Ideal for automated plants

• Broad operating range

• High efficiency

ICL’s compact design greatly enhances brownfield upgrade possibilities by minimizing installation cost, time and space requirements. Once installed, it increases productivity through significantly lower maintenance requirements. There are no friction points, so the ICL can start and stop quickly, and it’s well suited for gas network management and unmanned

stations in remote locations. Producing about half the noise of a traditional product, ICL is also a better fit with its surrounding environment; and there’s no oil or gas leakage, which further improves EHS performance. It’s extremely flexible and efficient — one machine performs both injection and withdrawal — minimizing energy consumption while producing no NOx or CO2 emissions.
