Hydrocarbon Dew Point Control Applications
Reduce heavy hydrocarbon content without refrigeration
Pipeline gas purity specifications are highly specific and typically require a hydrocarbon dew point to avoid condensation. Traditionally, the dew point has been controlled by methanol injection or glycol dehydration followed by expansion or mechanical refrigeration to low temperatures. Where the feed gas is rich in heavy hydrocarbons, refrigeration plants can be attractive when sufficient Natural Gas Liquids (NGL) liquid product can be recovered to add value to the overall product streams.
PEEK-Sep Solution
PEEK-Sep membranes can provide gas treatment solutions that meet pipeline hydrocarbon dew point requirements in cases where the amount of NGL is too low to allow for economic recovery. The membrane system is simple and reliable and does not require extensive feed gas pre-treatment beyond an inlet coalescing filter. Heavy hydrocarbons and other impurities are removed as a low pressure permeate stream, while generating a high pressure product stream that meets the pipeline specification. The reject permeate stream finds use as a fuel or is recompressed for further processing.
