Abstract
Conditioning of natural gas (NG) for sales requires meeting water- and hydrocarbon-dew points (WDP and HCDP, respectively) while assuring high heating value (HHV) specifications achievable through minimal extraction of C₅₊ components (NGL).
Authors compare technically and economically a supersonic separator technology – Twister^®, which can promote simultaneously WDP, HCDP and enhanced NGL extraction – to a conventional gas treating technology, consisting of an onshore natural gas dew pointing plant with TEG Dehydration unit coupled to a Joule-Thomson/Low Temperature Separation unit (TEG + JT/LTS).
