1. volatility in between - ?
2. slipping branched mercaptans - slipping разветвленные меркаптаны ?

Since the lightest branched mercaptan is iso-propyl mercaptan having a volatility in between n-pentane and n-hexane, the slipping branched mercaptans are removed from the gas in the gas processing unit and will end up in the C5+ fraction and sent to the condensate stabilization unit.
