Abstract
The utility model provides a residual liquid recovery device of a natural gas compressor. An inlet valve of the compressor is connected with an inlet separator; the inlet separator is connected with a stable negative pressure compressor; a check valve and an outlet valve are emptied, so that a reflux valve between an outlet of the stable negative pressure compressor and the inlet separator is removed; instead, the outlet valve is connected with a liquid recovery air inlet valve; the liquid recovery air inlet valve is connected with a residual liquid tank; a liquid recovery outlet valve and a safety valve are connected on the residual liquid tank; the residual liquid tank is connected with the inlet separator by a self-flowing valve; the safety valve is emptied; and the liquid recovery outlet valve is connected with a light oil tank. The idle rotation of the compressor caused by liquid recovery is effectively avoided, so that the small line efficiency of a raw oil stabilizing device and the light hydrocarbon recovery rate of the raw oil stabilizing device are improved.
Description
Technical field
The utility model relates to a kind of natural gas compressor, especially a kind of compressor raffinate recovering device.
Background technique
The major function of crude oil stabilizer is the light hydrocarbon component that reclaims in the crude oil, reduces the evaporating loss in storage and the conveying.Natural gas compressor gets into cylinder generation liquid hammer accident in order to prevent liquid in running, in compressor inlet entrance separator has been installed, and adopts empty machine running, utilizes outlet pressure to press the mode of oil to receive liquid.Because the import separator is too small, its safe volume is merely 1.2m
3, get into cylinder in order to prevent liquid, received the liquid average time interval 3.9 hours, receive the liquid time average is 0.47 hour at every turn, always receiving the liquid time is 2.9 hours/day.This receipts liquid mode can have influence on lighter hydrocarbons output on the one hand, frequently receives the normal operation that liquid has a strong impact on equipment on the other hand, has increased worker's labor intensity.
The model utility content
The purpose of the utility model is to avoid the deficiency of existing technology and a kind of natural gas compressor raffinate recovering device is provided.
The technical scheme of the utility model is: natural gas compressor raffinate retracting device, and compressor inlet valve is connected with the import separator, and the import separator is connected with stable negative pressure compressor; And by ball-and-seat and outlet valve emptying; Remove stablizing the outlet of negative pressure compressor and the return valve between the import separator, change outlet valve into and be connected, receive the liquid intake valve and be connected with residual liquid tank with receipts liquid intake valve; Connect on the residual liquid tank and receive liquid outlet valve and safety valve, and be connected with the import separator by the gravity flow valve; The safety valve emptying is received the liquid outlet valve and is connected with the light oil jar.
Compared with prior art, the utility model has the advantages that and avoid causing the idle running of compressor, thereby improve the operational efficiency and the lighter hydrocarbons recovery ratio of crude oil stabilizer, remarkable in economical benefits because of receiving liquid.
Description of drawings
Fig. 1 is that the structure of the utility model connects schematic representation.
Fig. 2 is that the background technique structure of the utility model connects schematic representation.
Among the figure: 1 is inlet valve, and 2 are the import separator, and 3 for to stablize the negative pressure compressor, and 4 is one-way valve, and 5 is outlet valve, and 6 for receiving the liquid suction valve, and 7 for receiving the liquid outlet valve, and 8 is residual liquid tank, and 9 is safety valve, and 10 are the gravity flow valve, and 11 is reflux valve.
Embodiment
Below in conjunction with accompanying drawing, specify the embodiment of the utility model.
As shown in Figure 2: natural gas compressor raffinate recovering device, compressor inlet valve 1 is connected with import separator 2, and import separator 2 is connected with stable negative pressure compressor 3, and through one-way valve 4 and outlet valve 5 emptyings.As shown in Figure 1: as will to stablize the outlet of negative pressure compressor 3 and the reflux valve 11 between the import separator 2 and remove; Changing outlet valve 5 into is connected with receipts liquid suction valve 6; Receiving liquid suction valve 6 is connected with residual liquid tank 8; Connect on the residual liquid tank 8 and receive liquid outlet valve 7 and safety valve 9, and be connected with import separator 2 through gravity flow valve 10; Safety valve 9 emptyings are received liquid outlet valve 7 and are connected with the light oil jar.
In use, the residual liquid tank valve 10 that flows automatically cuts out, utilize and stablize negative pressure compressor 3 outlet pressures oneself is pressed onto in the light oil jar with oil products in the residual liquid tank 8.After this recovering device was installed and implemented, the shutdown frequency of Negative pressure machine was reduced to 1 time/day by 6 times/day, received the liquid time and was also reduced to 1 hour by before 2.9 hours.After the raffinate recovering device is installed; Avoid causing the idle running of compressor because of receipts liquid; Thereby improve the operational efficiency and the lighter hydrocarbons recovery ratio of crude oil stabilizer; By the lighter hydrocarbons recovery ratio is 18.9kg/t, and crude charging capacity 70t/h calculates: day minimizing lighter hydrocarbons production yield loss 18.9 * 2.9 * 70/1000=3.84t/d, remarkable in economical benefits.
Claims (1)
