Compressors for the petrochemistry industry


Premium Engineering has commissioned a compressor unit at the ethylene oxide/glycol (EO/G) plant owned by SIBUR-Neftekhim (Dzerzhinsk, Nizhny Novgorod region).

The compressor unit is based on a two-stage MSG-3 centrifugal compressor manufactured by Cameron Compression Systems and driven by a Hyundai Heavy Industries induction motor. The unit will compress ethylene from 0.7 to 2.2 MPa(g). The compressor capacity is 315 mln kg/year in terms of fresh feed.

The new compressor is twice as energy efficient as the old ones. Also it reduces almost to zero losses of ethylene by using dry face gas seals.

This new fully automated compressor unit is part of the plant upgrading project and will boost the production of ethylene oxide from 200 to 240 tpy and of monoethylene glycol (MEG) from 170 to 200 tpy.
