Elliott Group has introduced a compressor designed for current and future low-carbon natural gas transmission networks that can take hydrogen blends up to 50%. The 140TCH pipeline compressor is available with electric drive and targets new and replacement pipeline stations with stringent NOx and CO2 emissions requirements, the company said.
The 140TCH is designed for increasingly complex restrictive emissions regulations. The compressor unit includes a 140TCH centrifugal compressor with a direct-coupled, high-speed induction motor powered by a variable-frequency drive (VFD) connected via a standard flexible coupling, Elliott said.
A standard geared solution is also available.
“In the United States, the situation for natural gas has changed dramatically with the development of local production of shale gas and the subsequent emphasis on reducing emissions. For these projects, the electric motor solution is optimal. In Europe, the growing need to import natural gas translates into a need to modify the gas transmission and distribution network, and electric compressors are accepted as a low-emission alternative to gas turbines,” said Todd. Omatick, product introduction manager.
Elliott’s 140TCH pipeline compressor comes with a variable speed direct-connect (VFD) motor and standard footprint with custom aerodynamics for optimum efficiency and extended run time between scheduled overhauls.
The gearless configuration of this compressor assembly offers a number of advantages including a smaller footprint, reduced lubricating oil requirements and higher net efficiency.
The pipeline compressor’s single-lift plug & play design includes ancillaries (lube oil, buffer gas panel, and integrated, custom controls), and piping and wiring are included on the skid for easy and quick installation with less work on site.
It is available seamlessly for applications from 10 to 35 MW. In addition, easy access to internal compressor components helps reduce maintenance costs.
Elliott Group designs, manufactures and services centrifugal and axial compressors, steam turbines, energy recovery expanders, and cryogenic pumps and expanders used in the petrochemical, refining, oil and gas, and liquefied gas industries. The company employs 2,600 people in 30 locations around the world. Elliott Group is a wholly owned subsidiary of Ebara Corporation, based in Tokyo, Japan.
