Description
Technical field
The utility model relates to a kind of crude oil individual well light oil recovery unit, belongs to Petro-Chemical Machinery, is a kind of device that from remote crude production oil well petroleum tank, reclaims lightweight oil.
Technical background
For remote crude production oil well, because there is not pipe network, the crude oil of producing all is to be stored in the multi-functional oil tank of individual well.Because in the crude oil multiple hydro carbons composition is arranged, and in crude production, often produce association lighter hydrocarbons gas, in addition, the multifunctional crude oil jar also will often heat, heating causes more lighter hydrocarbons gas to produce.In order to keep multi-functional tank pressure control within the specific limits, the frequent emptying of multifunctional crude oil storage tank often contains methane in dropping a hint; Lightweight oil; Components such as liquefied gas had both been polluted environment, had also been wasted the energy, and the light oil recovery unit to the crude production individual well is not arranged at present as yet.In order to improve production of hydrocarbons zone operating environment and save energy, the retrieving arrangement of lightweight oil improves associated gas comprehensive utilization ability in needing that exploitation is a kind of and dropping a hint to the individual well Multifunction tank.
The utility model content
The utility model technical problem to be solved provides a kind of crude oil individual well light oil recovery unit, and is low to solve remote crude production oil well organic efficiency, the problem that environmental pollution is serious.
The utility model solves the technical scheme that its technical problem adopted: crude oil individual well light oil recovery unit comprises strainer, under meter, first-class heat exchanger, secondary heat exchanger, SV, gas-liquid separator, liquidometer.Emptying oil gas from individual well multifunctional crude oil storage tank filters through strainer earlier, by under meter flow signal is passed to refrigerator, carries out precooling through first-class heat exchanger earlier, and then further cools off through secondary heat exchanger.Get into gas-liquid two-phase separator through the cooled gas of secondary heat exchanger, the gas temperature of secondary heat exchanger outlet is less than the condensing temperature under the normal pressure of lightweight oil, and behind the entering gas-liquid two-phase separator, lightweight oil is separated.Remain cooling gas in order to utilize in the gas-liquid two-phase separator behind the separation of lighter oil, residual gas gets into first-class heat exchanger and comes gas to carry out precooling to individual well multifunctional crude oil storage tank.Between secondary heat exchanger and gas-liquid two-phase separator, be provided with TM, through the refrigerating duty of temperature signal and flow signal control refrigeration system.
The beneficial effect of the utility model is to take the refrigerating duty intelligent control of secondary heat-exchanger rig and refrigeration system, good refrigeration effect, recovering of vaporized hydrocarbons rate height; Apparatus structure is simple, adopts whole skid, is convenient to install and transportation; The plant automation degree is high, and is safe and reliable.
