Oil Refining & Biofuel Production

All processes that need reciprocating compressors to convert crude oil feedstock into a variety of commercial products such as oil fuels, lubricants etc. Our valves fit also to the new processes for the biofuel production.

Compressors in oil production and refining industry have been using since the Fifties Cozzani valves designed and set up according to the type of gas and to the different working conditions in which such compressors operate. The speed range of these compressors is from 300 to 1200 rpm with stroke up to 400 mm and cylinder diameter up to 1200 mm.

The choice of material is very important to guarantee the compatibility with the various gases. When required the design is carried out in compliance with international norms as API 618 and NACE MR0175.

In this field, valves with thermoplastic sealing elements are being used more often, for example plate valves as the PD series valve type as well as ring valves with flat (CP valve type) or profiled (SR series valve type) sealing surface for high efficiency , which can operate in dry or lubricated compressors.
