THIOLEX™ technology employs the FIBER FILM® Contactor as the mass transfer device and utilizes caustic as the treating reagent to remove acid gas and mercaptan compounds from liquid and gas hydrocarbon streams.

THIOLEX™ technology was first licensed in 1980 and to date Merichem has granted 220 unit operating licenses world-wide. The non-dispersive FIBER FILM® Contactor achieves reduced capital expenditure and less plant space requirements compared to most treating alternatives, making THIOLEX™ the technology-of-choice.
