Compact, Efficient, Reliable

The Compander (TM) meets key needs in many of today's industrial processes where efficiency, a smaller footprint and faster installation times are key factors in equipment purchase decisions

Technical description of the Compander (TM)

Our Compander (TM) is designed to handle all gases and delivers volume flows of up to 480 000 m3/h over 8 stages, operating at a rated power of up to 30 MW. It’s a solution that meets key needs in many of today’s industrial processes, where energy efficiency is a major operations focus. Utilizing the full energy recovery potential for combined compression and expansion processes, the Compander (TM) merges our long standing expertise in integral gear technology and turbo expanders into one solution. It’s unique in that compressor and expander stages are housed in one gear box. You can use the energy recovered on the turboexpander side to power the compressor’s energy cycle, significantly reducing the compressor’s energy consumption (rotor drive). Our nitrogen and methane companders can be used in different LNG and chemical applications, respectively:

Nitric acid
Small-Scale LNG
HPPO
Caprolactam
Phenol
Boil off gas reliquefaction
Nitrous oxide
