DETAILED DESCRIPTION
[0028] The following will be combined with the embodiments to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.
[0029] See Figure 1 This embodiment provides a scattered gas recovery integrated hydrocarbon recovery skid:
[0030] like Figure 1As shown, the integrated hydrocarbon recovery skid for scattered gas recovery includes a filter FL01, a first separator V01, a second separator V02, a heat exchanger E01, a refrigerator Q01, a natural gas input pipeline, a product gas pipeline, a venting pipeline, and a condensate oil pipeline. The inlet of the filter FL01 is connected to the natural gas input pipeline, and the first outlet of the filter FL01 is connected to the inlet of the first pipeline of the heat exchanger E01 via a first connecting pipe; the outlet of the first pipeline of the heat exchanger E01 is connected to the inlet of the refrigerator Q01 via a second connecting pipe, the outlet of the second pipeline of the heat exchanger E01 is connected to the product gas pipeline via a third connecting pipe, and the outlet of the third pipeline of the heat exchanger E01 is connected to the inlet of the second separator V02 via a fourth connecting pipe; the outlet of the refrigerator Q01 is connected to the inlet of the first separator V01 via a fifth connecting pipe. Connection; the first outlet of the first separator V01 is connected to the inlet of the second pipeline of the heat exchanger E01 through the sixth connecting pipe, the second outlet of the first separator V01 is connected to the inlet of the third pipeline of the heat exchanger E01 through the seventh connecting pipe, and the third outlet of the first separator V01 is connected to the vent pipeline through the eighth connecting pipe; the first outlet of the second separator V02 is connected to the product gas pipeline through the ninth connecting pipe, the second outlet of the second separator V02 is connected to the condensate oil pipeline, and the third outlet of the second separator V02 is connected to the vent pipeline through the tenth connecting pipe.
[0031] The working process of the integrated hydrocarbon recovery skid for scattered gas recovery in this embodiment is as follows: the raw gas (H2S≤15mg / m3) from the previous process enters the filter FL01, which filters out the dirty oil and water in the raw gas. The filtered raw gas enters the heat exchanger E01, which performs a preliminary cooling on the raw gas, for example, cooling the raw gas to -21°C; the raw gas enters the refrigerator Q01 from the heat exchanger E01, which further cools the raw gas, for example, cooling the raw gas to -35°C-40°C, and then enters the first separation The dehydrogenated product gas, condensate oil and vent air are separated by the separator V01. The product gas and condensate oil enter the heat exchanger E01, and the vent air enters the vent pipeline. After heat exchange in the heat exchanger E01, the temperature of the product gas rises to 36.9°C. After passing through the heat exchanger E01, the product gas enters the product gas pipeline. After heat exchange in the heat exchanger E01, the temperature of the condensate oil rises to 34.9°C. After passing through the heat exchanger E01, the condensate oil further separates into product gas, condensate oil and vent air through the second separator V02.
