Sepra-Chem Corporation has developed proprietary technology for removing entrained liquids, including liquid aerosols from natural gas. Vessels used in this service are called "Coalescers." Sepra-Chem has an innovative approach based on the physical properties of the liquid removed and operating conditions. Natural gas components and liquid physical properties are used to calculate the energy level required to entrain liquid. The Sepra-Chem design assures this critical energy level is never exceeded within the Coalescer. Sepra-Chem Coalescers completely remove liquid and liquid wetted solids including iron sulfide preventing all downstream contamination.
