ABSTRACT:
Two versions of centrifugal type separators capable of removing moisture from digester gases, landfill gases and raw natural gases, each separator including an upright housing having a cylindrical upper region (of a circular cross-section) and a conical lower region which tapers downwardly. A tangential inlet is located in an upper region of the housing. A gas outlet is located centrally in a top end of the housing. An outlet to remove separated liquid is provided at the bottom of the housing. There is a trap system that preferably includes a liquid holding tank for providing a positive water seal in order to prevent explosive gases from escaping through the liquid outlet. One version of separator is suitable for a high pressure gas stream, i.e., 3.0 psig or higher, while the second version is suitable for lower pressure gas streams, i.e., from 6 inches to 30 inches of water. In the second version, the water seal is formed in the conical lower region of the housing and its water level is maintained by the location of an upper end of a drain outlet line. A vent line is open to atmosphere to maintain atmospheric pressure in the drain line.
