Description
Technical field
The present invention relates to petrochemical industry, especially a kind of device for recovering oil and gas.
Background technology
Oil has as a kind of important strategic materials and energy reserves in the economic development of country and Defence business
Very important status.With the rapid development of current science and technology, oil exploration of the China in petroleum industry application range,
Existing safety problem is gradually resolved during oil development etc..But China is during Oil ＆ Gas Storage at present
A series of problems, such as there are technology, facilities and administrations so that a part of lighter hydrocarbons substance of China's oil escapes into air, this
Kind phenomenon is exactly the Loss of Oil Evaporation often said, is economically that the heavy losses that China is brought are self-evident, in the environment
Caused by destroy it is even more inestimable.
In recent years, on internal and international one is achieved in terms of the workaround that research reduces oil storage tank Loss of Oil Evaporation
A little significant effects, method probably include two classes：First, the condition of limitation oil gas evaporation；Second is that making steaming using certain method
The oil gas issued does not diffuse into air, and so that it is condensed into liquids recovery by certain means.
In terms of the evaporation conditions of limitation oil gas, we can optimize operation：Intermediate products storage is reduced using DFF Direct Fuel Feed
Amount is reduced and is reconciled and tank switching number；Using the paint for oil tank that reflection effect is larger, oil storage tank appearance coating is reduced to temperature in tank
Influence；Using pressure vessel, installation breathing valve guard improves the two-way pressure of Tank's Breather Valve control, reduces oil storage tank
Big and Small Breath loss；Using arch-roof tank, increase nitrogen seal system, oil-gas space is reduced, to reduce Loss of Oil Evaporation.
In terms of petroleum vapor recovery, we may be used：Absorption method, condensation method, absorption process and membrane separation process etc..Absorption method is
The oil gas of effusion is absorbed using suitable adsorbent, such as entrucking generation oil gas is passed through into the adsorption tanks equipped with activated carbon
Afterwards, 99% or more alkane will all be absorbed；Condensation method is will to recycle oil gas by condensing agent, utilizes heat exchanger condensing recovery
Oil gas, this method principle is simple, and recycling oil product can be used directly；Absorption process be the mixed gas of oil gas and air is passed through it is appropriate
Absorbent, one or more ingredient in oil gas is dissolved in absorbent, and undissolvable part is retained in mixed gas
In, to realize the component separation of mixed gas；Membrane separation process is that oil vapour is utilized at different speeds, to be spread with air
Rate and the principle of different solubility realize separation, in this way, the rate of recovery of oil gas can be made to reach 95% or so.
The present invention provides a kind of device for recovering oil and gas, and tank interior is balanced by the design of unidirectional fire-retardant breather valve
Pressure balance has ensured completeness and the safety of petroleum vapor recovery.
Invention content
It is an object of the invention to design to balance the pressure balance of tank interior by the unilateral initiative of fire-retardant breather valve,
Completeness and the safety of petroleum vapor recovery are ensured.
The present invention solve above-mentioned technical problem the technical solution adopted is that：A kind of device for recovering oil and gas includes oil storage tank, resistance
Fiery breather valve, oil gas vent and recovery channel, fire-retardant breather valve and oil gas vent are arranged in the top of oil storage tank, fire-retardant breather valve
For unilateral initiative, unilateral initiative pressure is 295Pa, and air can enter tank body by fire-retardant breather valve, but oil gas can not pass through
Fire-retardant breather valve is overflowed or is shed.Oil gas vent is connect with recovery channel, and being connected to the oil gas equipped with activated carbon by pipeline inhales
Attached tank or condensate recycling device with heat exchanger have the oil gas absorbing device of appropriate absorbent or membrane separation process oil gas to return
Receiving unit.
It is designed by the unilateral initiative of fire-retardant breather valve to balance the pressure balance of tank interior, realizes 100% oil
Gas is recycled, and has ensured the completeness of petroleum vapor recovery.Fire-retardant breather valve, oil gas vent and recovery channel constitute a whole set of oil gas
Retracting device simplifies oil-gas recovery device, and the reduction of pipeline increases safety, avoids all oil storages of traditional oil-gas pipeline
Dangerous situation once occurs for the problem of tank unicom air inlet, pipeline unicom air inlet, is easy to be connected to and causes big loss together.And it is of the invention
It can then solve the problems, such as this, increase safety, while reduce quantities and investment.
The positive effect of the present invention is：Steam inlet pipe road is substituted by unidirectional fire-retardant breather valve, simplifies petroleum vapor recovery dress
It sets, function may be implemented to substitute completely, and the reduction of pipeline increases the security performance of system.It is all to avoid traditional oil-gas pipeline
Dangerous situation once occurs for the problem of oil tank unicom air inlet, pipeline unicom air inlet, is easy to be connected to and causes big loss together.And it is our
Case can then solve the problems, such as this, increase safety, while reduce quantities and investment.
