Description
Technical field
The present invention relates to a kind of environmental protection equipment, the vitals in the useless withdrawal receiving apparatus that especially a kind of petroleum chemical industry uses, specifically a kind of low pressure flare filtering tank.
Background technology
As everyone knows, torch gas exhaust system is the important escape way of petrochemical plant, reclaims available resources under the prerequisite that guarantees exhaust system safety as far as possible, reaches the unification of security and economy.
According to the component and the discharging parameter of petrochemical industry, refinery different device discharging torch gas, divide matter, dividing potential drop to reclaim, the torch gas of recovery utilizes mode to be divided into raw material type and fuel type two big classes:
The raw material type promptly is with all or part of raw material as device of the torch gas that reclaims, and mainly directly send PSA to make hydrogen feedstock with pipe special in the rich hydrogen torch gas of high pressure or pressurization back at present, reclaims H
2Other olefines chemical classes waste gas products need be done the research of further purification processes technology.
Fuel type promptly is the torch pneumatic transmission gas holder that reclaims to be made industrial heating furnace fuel use after focusing on.General industry stove burner, boiler tube design by special component, and sulfur content in the fuel gas is had strict demand, if reclaim torch gas calorific value, component instability, will directly influence the operation of device economic security.And general thermal power plant boiler capacity is big, and fuel tolerance is strong, torch pneumatic transmission power plant can be made boiler oil.Can divide two classes to use by the characteristic of fuel gas: to reclaim that unprocessed torch pneumatic transmission steam power plant, device boiler make fuel and through pretreated torch gas.
Because the discharging of torch gas does not have rule to follow, its component, impurity, lime set content can not estimate that all in service in flare gas recovery system, the problem of often running into is to stop up, wherein except that the obstruction of pipeline, pipe fitting, more reluctant problem is the obstruction of compressor.Therefore, it is to guarantee that gas equipment is long-term, the key of efficient operation that torch gas is carried out filtration treatment, for this reason, need can guarantee the safe operation of recovery compressor at the characteristics design of torch gas is a kind of, the different influences that produce of back pressure when avoiding the discharging of many covering devices guarantee stable, safety, the operation reliably of each cell arrangement recovery system.
Summary of the invention
