Vapor condenser for vapor recovery systems

Abstract

A vapor condenser for a system and apparatus for condensing and recovering vapors of low volatile liquids such as hydrocarbons has a U-shaped passage therethrough with one end of said U-shaped passage in communication with an inlet for vapors of the low volatile fluids to be condensed and the other end of said U-shaped passage is in communication with a discharge outlet for non-condensible gases, finned coil sections having passages for passing cooling fluid therethrough are disposed in said U-shaped passage, said finned coil sections having the fins thereon more widely spaced adjacent the inlet end of the U-shaped passage and the fins being more closely spaced on the finned section progressively the more remote the finned sections are from the inlet to the U-shaped passage, and the fins on the more closely spaced finned coil sections being lined up with the fins on the widely spaced finned coil section of the U-shaped passage, a collecting chamber at the end of said U-shaped passage remote from the inlet end, and a drain for passing condensate from the vapor condenser. Additionally, a vapor condensing and recovery assembly including the vapor condenser above described, a decanter, and a circulating system for maintaining the collection chamber for the vapor condenser, the outlet passage for the vapor condenser, the inlet passage for the decanter, and a separating chamber in the decanter respectively at temperatures to increase the temperature of the condensate to approximately 60.degree. F to 65.degree. F.
