Detailed Description
The technical solution of the present invention will be fully and clearly described below with reference to the accompanying drawings.
The gas field gas collection booster station energy circulating device comprises a water jacket heating furnace 1, a compressor filtering separator 2, a compressor 3, a compressor rear heat exchanger 4 and a circulating water booster pump 5, wherein a low-pressure gas pipeline 6 is connected with the compressor filtering separator 2, the compressor filtering separator 2 is connected with the compressor 3, the compressor 3 is communicated with the compressor rear heat exchanger 4, the compressor 3 applies work to the booster gas, the pressure of the booster gas is increased while the temperature is increased, the booster gas reaches the compressor rear heat exchanger 4, the compressor rear heat exchanger 4 is connected with the water jacket heating furnace 1 through the circulating water booster pump 5, and one end of the water jacket heating furnace 1 is communicated with the compressor rear heat exchanger 4.
The water jacket heating furnace 1 is connected with an outlet of a heat exchanger 4 behind the compressor, a heating medium is desalted water, and the circulating water booster pump 5 is utilized to realize that low-temperature water absorbs heat from the low-pressure gas well through pressurization to release the heat from the high-pressure gas well water jacket heating furnace 1.
The water jacket heating furnace 1 is connected with the high-pressure gas well, and the heating and throttling of the high-pressure gas well are realized by utilizing the water jacket heating furnace 1.
And the compressor 3 and the pressurized high-temperature gas are connected with a compressor heat exchanger.
Example A
The low-pressure gas firstly enters the compressor filter separator 2 through the low-pressure gas pipeline 6, and enters the compressor 3 for pressurization after gas-liquid separation. Because the compressor 3 does work on the pressurized gas, the pressure of the pressurized gas is increased while the temperature is raised, the pressurized gas enters the heat exchanger 4 behind the compressor, the high-temperature pressurized gas exchanges heat with the low-temperature circulating water, and the low-temperature pressurized gas is directly output after heat exchange; after the temperature of the circulating water rises, the circulating water is pressurized by a circulating water booster pump 5, the water jacket heating furnace 1 is removed, gas well incoming gas and gas after primary throttling are heated in the water jacket heating furnace 1, the temperature of the gas well incoming gas after throttling is higher than the hydrate forming temperature, and pipelines are not blocked. After the water jacket heating furnace 1 exchanges heat with gas from a gas well, the low-temperature circulating water returns to the compressor rear heat exchanger 4, and the heat exchange between the pressurized gas and the circulating water is carried out again, so that the effective utilization of the energy in the station is realized.
Example B
According to the method, HYSYS software is adopted for modeling analysis, and the following examples are shown: when the inlet pressure of the compressor 3 is 1MPa and 10 ten thousand square/day gas is pressurized to 4.5MPa, the outlet gas of the compressor 3 is cooled to 35 ℃, the temperature of cooling water is increased to 80 ℃ from 30 ℃, and the circulating water is needed to be about 111.9 t/d; the heated circulating water is heated and throttled, and then the gas comes from the high-pressure gas well, so that the requirement that the high-pressure gas well is throttled from 25MPa to 4.5MPa in 14 ten thousand square/day is met, and the temperature of the circulating water is reduced to 30 ℃ from 80 ℃. After conversion, theoretically, the low-pressure gas per 1 ten thousand square can meet the throttling requirement of the high-pressure gas per 1.4 ten thousand square.
