Abstract
The utility model provides a device for separating liquefied natural gas reshuffles part, including the one -level pump, condensation heat exchanger, domethanizing column and heat exchanger and deethanizer and liquefied petroleum gas storage tank have been connected gradually on the one -level pump, the deethanizer still is connected with the condensation heat exchanger, still be connected with ethane storage tank and two stage pump on the condensation heat exchanger. Ethane and propane and above component among the liquefied natural gas can be isolated to this device to the cold volume of utilizing liquefied natural gas self makes the condensation of desorption ethane and propane component become liquid after former gasification equipment is returned in the pump pressure boost.
Description
Technical field
The utility model belongs to technical field of petrochemical industry, is specifically related to a kind of device for separating of natural gas liquids heavy component.
Background technology
At present, natural gas liquids generally adopts the mode of gas supply conduit after gasification, and therefore a lot of heavy component is applied together with methane gas, application can efficiency lower.Its natural gas liquid changes greatly, and for the liquefied natural gas product that methane content is lower, utilize deethanizing column to deviate from the method for propane and above component, a large amount of ethane component is still in natural gas liquids is evened out.After the natural gas liquids removing propane components utilizes compressor boost, enter gas pipe line, energy consumption is larger.
Utility model content
The purpose of this utility model is to provide a kind of device for separating of natural gas liquids heavy component, ethane in natural gas liquids is separated respectively with propane and above component, the Sweet natural gas of rejecting ethane and propane components carries out heat exchange with the natural gas liquids entered, condensation becomes after liquid through pump supercharging, return Primordial Qi gasifying device, solve the larger problem of compressor boost energy consumption.
The technical scheme that the utility model adopts is, a kind of device for separating of natural gas liquids heavy component, comprises primary pump, primary pump is connected with condensing heat exchanger, demethanizing tower and interchanger and deethanizing column and liquefied petroleum gas storage tank in turn; Deethanizing column is also connected with condensing heat exchanger; Condensing heat exchanger is also connected with ethane storage tank and two stage pump.
Further, condensing heat exchanger comprises the first condensing unit, the second condensing unit and the 3rd condensing unit.
Further, primary pump is connected with two stage pump with the top of the second condensing unit, demethanizing tower, the first condensing unit successively.
Further, ethane storage tank is connected with deethanizing column with the 3rd condensing unit successively.
The beneficial effects of the utility model are: this device can isolate ethane in natural gas liquids and propane and above component, and utilize the cold of natural gas liquids self to make the condensation of rejecting ethane and propane components become after liquid through pump supercharging, return Primordial Qi gasifying device.
Accompanying drawing explanation
Fig. 1 is the structural representation of the device for separating of natural gas liquids heavy component.
In figure, 1. primary pump, 2. condensing heat exchanger, 3. demethanizing tower, 4. interchanger, 5. deethanizing column, 6. ethane storage tank, 7. liquefied petroleum gas storage tank, 8. two stage pump, 9. the first condensing unit, 10. the second condensing unit, 11. the 3rd condensing units.
Embodiment
Below in conjunction with embodiment, the utility model is described in detail.
The utility model provides a kind of device for separating of natural gas liquids heavy component, as shown in Figure 1, comprises primary pump 1, primary pump 1 is connected with condensing heat exchanger 2, demethanizing tower 3 and interchanger 4 and deethanizing column 5 and liquefied petroleum gas storage tank 7 in turn; Deethanizing column 5 is also connected with condensing heat exchanger 2; Condensing heat exchanger 2 is also connected with ethane storage tank 6 and two stage pump 8.
Wherein, condensing heat exchanger 2 comprises the first condensing unit 9, second condensing unit 10 and the 3rd condensing unit 11.Primary pump 1 is connected with two stage pump 8 with the top of the second condensing unit 10, demethanizing tower 3, the first condensing unit 9 successively.Ethane storage tank 6 is connected with deethanizing column 5 with the 3rd condensing unit 11 successively.
The using method of this device is: natural gas liquids pressurizes through primary pump 1, the second condensing unit 10 entering condensing heat exchanger 2 carries out heat exchange with the Sweet natural gas of rejecting ethane and propane and above component, then demethanizing tower 3 is entered, separation obtains methane gas and ethane and above component fluids, methane gas is partly refluxed to demethanizing tower 3 top, and part enters the first condensing unit 9 of condensing heat exchanger 2, is converted into liquid, enter two stage pump 8 supercharging, return Primordial Qi gasifying device.Ethane and the above component fluids of demethanizing tower 3 enter interchanger 4, then deethanizing column 5 is entered, separation obtains ethane gas and propane and above component fluids, ethane gas part enters deethanizing column 5 top, part enters the 3rd condensing unit 11 of condensing heat exchanger 2, be converted into liquid, enter ethane storage tank 6.Propane and above component fluids enter liquefied petroleum gas storage tank 7.
This device overcomes the deficiency that its natural gas liquid is underused, and the ethane in natural gas liquids can be separated respectively with propane and above component, overcome the deficiency that gas compressor supercharging energy consumption is higher, methane gas is converted to fluid pressurization and returns.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, many variations can also be made to it.
