Abstract
The utility model discloses a light hydrocarbon recovery unit, which comprises an air compressor, a heat exchanger and a gas-liquid separator communicated with the heat exchanger. The light hydrocarbon recovery unit is characterized in that a vortex tube is arranged between the air compressor and the heat exchanger. The unit is reasonable in structure, high in connecting universality and complete in function. A special refrigeration compressor and traditional various refrigerants are abandoned, so that heavy components above propane can be condensed into liquid, light hydrocarbon in oilfield associated gas is recovered, investment can be saved, and environmental pollution is relieved.
Description
Technical field
The utility model relates to a kind of light ends unit, especially a kind of light ends unit with vortex tube refrigeration.
Background technology
In oil and gas exploitation, associated gas is owing to contain the high propane of a large amount of added values, butane (liquefied petroleum gas (LPG) component) and lightweight oil, generally all need to adopt the outer loop refrigeration, the temperature of associated gas is reduced to below-30 ℃, the heavy constituent condensation more than the propane is wherein become liquid separation comes out, general the most frequently used is to adopt refrigeration compressor set, in interchanger, utilize the liquefaction of refrigeration agent---the principle that gasification need be absorbed heat, make the temperature of Sweet natural gas be reduced to carrying out gas-liquid separation below-30 ℃ and obtaining the liquid lighter hydrocarbons of requirement, but there is the power consumption of compressor in this course, problems such as the leakage of refrigeration agent and heat-exchanging process complexity particularly adopt freonll-11, also can cause very big harm during ammonia refrigerant to environment.
The utility model content
At the deficiency that prior art exists, technical problem to be solved in the utility model is, a kind of light ends unit is provided, and both can make the above heavy constituent of propane be condensed into liquid, and the lighter hydrocarbons in the recovery Sweet natural gas can be reduced investment outlay again, alleviate environmental pollution.
For solveing the technical problem, technical solution adopted in the utility model is: a kind of light ends unit, and it comprises air compressor, interchanger and the gas-liquid separator that is communicated with it; It also is provided with vortex tube between air compressor and interchanger.
Optimize, interchanger is selected plate-fin heat exchanger for use.
Light ends unit of the present utility model, it utilizes the refrigeration principle of vortex tube, obtains cold air flow about-50 ℃ at the cold junction of vortex tube, and makes it in interchanger and the Sweet natural gas heat-shift.This apparatus structure is reasonable, connects highly versatile, telotism, abandon under the situation of special-purpose refrigeration compressor and traditional various refrigeration agents, both can make the above heavy constituent of propane be condensed into liquid, the lighter hydrocarbons in the recovery associated gas, can reduce investment outlay again, alleviate environmental pollution.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
As shown in Figure 1, a kind of light ends unit, it comprises air compressor 1, vortex tube 2, plate-fin heat exchanger 3 and the gas-liquid separator 4 that is communicated with plate-fin heat exchanger 3; Air compressor 1 is communicated with the inlet mouth of vortex tube 2, and the cold air outlet of vortex tube 2 is communicated with the refrigerant import of plate-fin heat exchanger 3, and the discharge port of plate-fin heat exchanger 3 is communicated with gas-liquid separator 4.
This light ends unit is applied to oil field Sweet natural gas retrieving arrangement with vortex tube, with air as refrigeration agent, utilize-50 ℃ of left and right sides cold air streams that vortex tube 2 cold junctions produce in plate-fin heat exchanger 3 with heat exchange gas, the temperature of Sweet natural gas is reduced to below-30 ℃, reaches traditional refrigeration compressor refrigeration result the same with conventional refrigerants.
During this device work, enter vortex tube 2 after 1 supercharging of dried normal temperature air process air compressor, cold junction at vortex tube 2 obtains the cold air stream about-50 ℃, and the Sweet natural gas after this cold air stream and dehydration and the precooling all enters and carries out heat exchange in the plate-fin heat exchanger 3.Behind the heat-shift, natural gas temperature drops to below-30 ℃, enters gas-liquid separator 4 then and isolates light hydrocarbon product and dry gas, and dry gas is by defeated outward as product behind the cryogenic energy utilization, and liquid light hydrocarbon can also can enter the following process device directly as production marketing.
Claims (2)
1. light ends unit, it comprises air compressor, interchanger and the gas-liquid separator that is communicated with it; It is characterized in that: between air compressor and interchanger, be provided with vortex tube.
2. light ends unit according to claim 1 is characterized in that: described interchanger is a plate-fin heat exchanger.
