GE debuts its high-pressure ratio compressor (HPRC)
GE has introduced the high-pressure ratio compressor (HPRC). Billed as the company’s smallest and lightest compressor, the HPRC requires fewer units per train, reducing its overall footprint, the company said. These features mean a reduced shipping weight, easier installation, lower power consumption, increased reliability and reduced operating costs, GE said.
High-pressure ratio compression is a new technology that has been applied to GE’s BCL compressors line. GE also plans to apply it to MCL and ICL compressors. Applicable to many gas processes, it is designed for low and medium molecular weight mixtures. The best benefits can be realized for on and offshore natural gas.
HPRC’s technology is based on architecture that combines shrouded and unshrouded impellers on a single, high-speed shaft, achieving high efficiency thanks to full 3D aerodynamic profiles derived from an aircraft engine. Applications that would have required multiple compressor bodies will now require only one with GE’s HPRC because the compressors have an increased head per stage with a shorter bearing span, which reduces the number of compressor casings required.
The HPRC has completed a test bench process, including rotor testing up to 19,000 rpm. A full-scale prototype has been built, which will be continually tested to meet customer requirements. The new technology is available for GE Oil & Gas’ customers and will be manufactured at the company’s facility in Florence, Italy.
