Remove mercaptans from hydrocarbon condensates and NGL streams

D. ENGEL, EXION Systems, The Woodlands, Texas; and H. BURNS and S. WILLIAMS, Nexo Solutions, The Woodlands, Texas Here, the removal of mercaptan components from a hydrocarbon condensate stream at a Canadian gas plant, using a novel removal chemistry and separation technology, is investigated. The removal of mercaptans was required to meet pipeline specifications for total sulfur and mercaptan concentrations. The onsite work consisted of verification of the nonregenerable chemical additive for mercaptans removal in combination with a liquid treating process separation system. A miniaturized version of the removal process system was assembled onsite, and a 1.65-gpm slipstream of condensate w
