Abstract
A decanter for a system and apparatus for condensing and recovering vapors of low volatile liquids such as hydrocarbons has an inlet for the condensed vapors of the low volatile liquid, and an outlet for passing condensate from said decanter, a separating chamber in the decanter communicates with the inlet to receive condensate mixed with water and a second chamber communicates with the outlet, a transfer device permits separated condensate to pass to the second chamber and a heater is provided in the first chamber to maintain the water mixture above the freezing point thereof and preferably in a range from 40.degree. F to 70.degree. F.
Claims7
A vapor condensing and recovery assembly for recovering vapors of low volatile liquids such as hydrocarbons,
- a. vapor condensing means having, a housing,
- b. said housing having, an inlet means for passing vapors to be condensed to said vapor condensing means, and an outlet means for venting air and non-condensable gases from said vapor condensing means,
- c. U-shaped flow passage means in the upper section of said housing having, an entrance flow passage, and an exit flow passage,
- d. condensing means in said U-shaped flow passage means including, means on the condensing means to control the formation of frost and ice thereon,
- e. said entrance flow passage in communication with the inlet means and said exit flow passage in communication with the outlet means,
- f. a collecting space in said chamber disposed below the condensing means for collecting condensate from the condensing means.
- g. a decanter for separating the condensed vapor from the collected condensate and for recovering the same, and
- h. means connecting the collecting space in said housing to the decanter for passing collected condensate thereto.
A decanter for recovering condensed vapors of low volatile liquids, such as hydrocarbons,
- a. housing means,
- b. a partition in said housing means defining a separating chamber and a collecting chamber therein,
- c. an inlet port in said housing in communication with the separating chamber for passing condensate having condensed vapors of low volatile liquids therein to the separating chamber,
- d. means in the separating chamber for elevating the temperature of the separated condensed vapors,
- e. weir means on said partition for flowing separated vapors from the separating chamber to the collecting chamber, and
- f. discharge means in the housing for removing the collected condensed vapors of low volatile liquids from the collecting chamber.
