Description
Technical field
The utility model relates to a kind of molecular sieve adsorption device of the Sweet natural gas closed circulation regeneration that is applicable to oil field individual well gas dehydration.
Background technology
In oil production, Sweet natural gas is plucked out of as accompanying gas with crude oil, mostly burns by torch emptying in the past, causes waste.For save energy, be necessary the Sweet natural gas of oil field individual well to reclaim.
Because oil field individual well association Sweet natural gas contains saturated vapor, water recovery at normal temperatures becomes liquid water, its soluble sour gas and form acid solution, etching apparatus.Liquid water also can be combined with hydrocarbon and be formed gas hydrate, causes the obstructions such as pipeline, equipment, valve and instrument, gently reduces transmission efficiency, heavy security incident occurs; For this reason, must before Sweet natural gas enters pipe communication system, carry out processed, make the Sweet natural gas that enters pipe network meet the requirement of standard GB/T 17820 " Sweet natural gas " to water (hydrocarbon) dew point.
Gas dehydration adopts molecular sieve adsorption device mostly.When the molecular sieve adsorption water yield is saturated, must carry out just reworking after desorption and regeneration.At present, molecular sieve desorption and regeneration heats adsorbing tower with molecular sieve after normally the dry gas of certain pressure (Sweet natural gas dewaters) electrically heated being heated up, the moisture evaporation that makes to be adsorbed in molecular sieve separates out, after cooling with Sweet natural gas, enter resurgent gases separator and isolate free-water, Sweet natural gas after separation mostly is emptying, be that Sweet natural gas enters while goes out, not only heat-energy losses is large, and Sweet natural gas emptying causes the wasting of resources.
Summary of the invention
The purpose of this utility model is to provide a kind of molecular sieve adsorption device of the Sweet natural gas closed circulation regeneration that is applicable to individual well gas dehydration, is used in the Sweet natural gas circulation retrieval system of regeneration, avoids waste.
The utility model molecular sieve adsorption device comprises the adsorbing tower with molecular sieve, air cooler, separator, recirculation blower and the electric heater that are connected with pipeline, one end of described adsorbing tower with molecular sieve is connected with raw natural gas input tube simultaneously and resurgent gases output tube, the other end are connected with dehydration Sweet natural gas output tube and resurgent gases input tube simultaneously, and described each pipe is respectively equipped with valve; The resurgent gases output tube of described adsorbing tower with molecular sieve connects air cooler and separator successively, and the lower end of described separator connects draining output tube, and the resurgent gases input tube that upper end connects recirculation blower, electric heater and adsorbing tower with molecular sieve is successively connected.
Described adsorbing tower with molecular sieve is made up of two towers in parallel, and two towers switch use by valve, i.e. a job, and a standby regeneration is used.
Described adsorbing tower with molecular sieve, air cooler, separator, recirculation blower and electric heater integrated installation on same base, the skid-mounted device that formation can integrated moving.
In this molecular sieve adsorption unit, the regenerative process of adsorbing tower with molecular sieve is taking the Sweet natural gas that dewatered in its tower as resurgent gases, and resurgent gases is got back in former regenerator column after by air cooler, separator, recirculation blower and electric heater, forms the indirect regeneration of sealing.Be that this device adopts recirculation blower to make resurgent gases supercharging, after heating, enter in regenerator column, the water of molecular sieve internal adsorption is heated into after water vapour together with Sweet natural gas after resurgent gases air cooler is cooling, enter and in separator, isolate free-water, separate and discharge free-water, dehydration Sweet natural gas is sent regenerator column back to by recirculation blower, recycles.
In sum, the utility model recycles regeneration Sweet natural gas by recirculation blower, arranges outward without resurgent gases, has reduced heat-energy losses.
