Re: Compressed Natural Gas Cooler

The Problem:

This plant has 4 recip compressor units and 4 TEG dehydration units. The finfan coolers on the compressors are undersized and the gas outlet temperature from the finfans exceeds the dehy unit design inlet gas temperature of 100 deg F, resulting in gas to the pipeline with >7 lb/mmscf water content. On site we have available >2500 bbl/day of produced water at 70 deg F. Plant normal output is 60 MM @ 400 psig.

We are looking at several option, one of which is installing a gas cooler with water pumps instead of fans, all what we need .

The Request

1. Anyone implemented this approach successfully?
2. We are looking at decreasing the gas temp from 120 deg F to 95 deg. F?
3. I am looking for a ASME Certified design/fabricator in the USA only?

Thank a lot. ET.
