In addition, partially liq medium in the self-separation device adds the inlet of pump in the future, and can cool off gas phase in addition from the absorption tower, wherein the condensate that forms owing to the cooling gas phase shifts out from additional separator, and will join gas phase separation is become in the coil pipe of cold-peace hot gas medium from the gas phase of additional separator, then with the hot gas media discharge in atmosphere, and cold gas medium is used for cooling off the gas phase of leaving behind the absorption tower.
The gas phase of the tower of self-absorption in the future joins the aerodynamic force separator, therein owing to gas phase is cooled off in its acceleration and expansion, wherein formed from the condensate flow that remains in the hydrocarbon vapours in the gas phase, then condensate has been separated from gas phase and from the aerodynamic force separator, shifted out.
The hydrocarbon liquid with the gas phase hydro carbons that is dissolved in wherein of the tower of self-absorption in the future joins separator or pump intake.
In the future the hydrocarbon liquid with the gas phase hydro carbons that is dissolved in wherein of self-absorption tower joins the container that stores oil product or by in its jar of packing into.
Liquid medium can be shifted out from separator and join the container that stores oil product or by its jar of packing into.
Can be with oil product, particularly the gasoline of petroleum refining or kerosene distillate join separator or pump intake.
The gas phase of leaving behind the absorption tower can be joined in the film device, wherein separate the gas phase hydro carbons that remains in wherein, then the gas of poor hydro carbons and the gas of rich hydrocarbon are shifted out from film device respectively.
Can from film device, extract the gas of rich hydrocarbon by liquid-gas jetting equipment out.
Can from film device, extract the gas of rich hydrocarbon by additional liquid-gas jetting equipment out.
Steam medium is in the reservoir vessel of oil product and at its dissimilar jars of packing into-form from the process of wherein extracting out, mainly is made up of air and hydrocarbon vapours.For example, under the situation of gasoline, the steam content of the oil product in steam medium can be 300 to 1500g/cm
3Or change in the higher scope.At gasoline in this case, in steam medium so the hydro carbons of high-load when it enters in the atmosphere, cause the pollution of environment and the loss of a large amount of oil product sold.Therefore, removing of hydro carbons is actual purpose from steam medium.Must prevent that hydro carbons from entering atmosphere and reducing the loss that can sell oil product.
Desired method can be removed hydro carbons then by extracting out and the compressed steam medium by means of the pump spraying equipment from medium, and the concentration of hydro carbons that will be in steam medium is reduced to and is lower than the level that the steam maximum that enters environment can allow of discharging.Wherein will be added into the liquid medium of liquid-gas jetting equipment as ejection medium by pump the most simultaneously, be used for from jar that oil product is housed or from the container that oil product stores, extract steam medium out, and be used for from the steam medium of extracting out, absorbing environmentally harmful hydro carbons.Be stored in the container or tank filling in the gasoline or the kerosene distillate of oil product, particularly petroleum refining, can be used as such liquid medium.Yet, for the effective ways that absorb hydro carbons from steam medium are provided, should create such condition, under this condition, should have saturated vapor pressure under the temperature that it is joined in the absorption tower as the hydrocarbon liquid of absorbent, preferably be significantly less than the saturated vapor pressure of the hydro carbons in the steam medium that in the storage of oil product and transportation, forms.In addition, must obtain the reduction greatly of the hydrocarbon liquid evaporation in absorption process itself.What determine under study for action is, from economic aspect, the most preferably the temperature with hydrocarbon liquid (gasoline, kerosene) is reduced to such temperature before it is joined the absorption tower, and this temperature is-10 ℃ to-50 ℃.When the temperature at hydrocarbon liquid is higher than-10 ℃, do not reach the effectiveness that absorbs hydro carbons from steam medium of requirement, and temperature is being when being lower than-50 ℃, the consumption of the electric energy of refrigeration machine significantly increases, and this can not be compensated by the increase of the absorbability of hydrocarbon liquid.Simultaneously, because the reduction of temperature, the viscosity of hydrocarbon liquid increases, and causes increasing the energy consumption of the operation of extracting it and absorption tower out.Therefore, in the parameter area of above-mentioned expression, guaranteed to install necessary operation and renderd a service and minimum energy consumption.
In the described in the above method, the multilevel process of the reaction of steam medium of extracting out (comprising hydro carbons) and hydrocarbon liquid.First reaction takes place in the liquid-gas jetting equipment, and wherein the liquid medium of mainly being made up of hydrocarbon liquid is used for the extraction and the compression of steam medium.In the output of spraying equipment, form two-phase mixture.In the process of reaction, beginning is absorbed the process of hydro carbons from steam medium by liquid medium.This process lasts till that the mixture in separator is separated into that time of liquid medium and gas phase, and described gas phase is for partly removing the steam medium of hydro carbons and compression.
Then, gas phase is joined in the absorption tower, therein,, carried out reducing the process of the hydrocarbon content in the gas phase there owing to react with the hydrocarbon liquid (gasoline or kerosene distillate) that joins the cooling.The contracurrent system that is provided for the motion of gas phase and hydrocarbon liquid in the absorption tower produces the condition that more helps absorbing from gas phase by colder hydrocarbon liquid hydro carbons.Compare with the concentration of hydro carbons in gas phase media, this makes and can significantly be reduced in the concentration that purifies the hydro carbons in the gas phase.In the future the partially liq medium of the self-separation device inlet that joins pump makes and can produce closed circuit: separator-pump-liquid-gas jetting equipment-separator, this has reduced the consumption that joins the fresh liquid medium of device from other source.The inlet that the hydrocarbon liquid of the tower of self-absorption in the future joins separator or pump is used for producing the process of the liquid medium renewal that will join liquid-gas jetting equipment.As the result who oil product (gasoline of petroleum refining or kerosene distillate) is joined the inlet of separator or pump, the process that circulating liquid medium is upgraded.Because in the operating process of device, will be transferred to from the hydro carbons of steam medium in the liquid medium, preferably from device, remove it and for example enter the container of oil product storage or enter the jar that to pack into.
Just as already noted, in the compression process of steam medium, the possibility that provides environmentally harmful hydro carbons to absorb.It should be noted, suction process or in other words, absorption process, it is understood to mean the process of dissolved gas in liquid medium, makes the liquid-gas jetting energy consumption of equipment that can reduce the steam medium that is used for the compressed package hydrocarbon-containifirst.This is due to the fact that acquisition: in vapour mixture compression be transported in the process of separator, carry out two independently processes-because the mechanical compress of the kinetic energy that liquid medium sprays and the dissolving of the part vapour mixture in liquid medium, wherein the process of back is along with raising and strengthened at the spraying equipment and the pressure of following the mobile part in its pipeline.The supply of the fresh liquid medium that shifts out and enter it of liquid medium provides the stable possibility that joins the composition of the liquid medium-hydrocarbon vapours absorbent in the spraying equipment from its closed circuit.This provides the more stable operation of spraying equipment, has kept the absorbability of liquid medium simultaneously.As a result, can obtain the balancing run of liquid-gas jetting equipment and in the future the gas phase of removing hydro carbons of self-absorption tower shift out and enter environment and pollutant is not introduced in the environment.
In many cases, the gas hydrocarbon impurities of the gas phase that adds can not be very cleared up on the absorption tower effectively from separator.This physical property with the process that absorbs the gas hydro carbons by hydrocarbon liquid is relevant.No matter how cool off hydrocarbon liquid consumingly, the content of the gas hydro carbons in gas phase can not be reduced to below the partial pressure value of hydrocarbon liquid.Therefore, size by increasing the absorption tower or the more complicated content that all cannot obtain gas phase hydro carbons in gas phase of structure that makes it are lower than the partial pressure value of hydrocarbon liquid under its operating temperature.
In the composition of gas phase, comprise under the situation of big percentage hydro carbons, preferably pass through, for example, use coil pipe or aerodynamic force separator to carry out follow-up cleaning, be used for cooling off in addition gas phase and separating hydrocarbons condensate and other impurity therefrom at it.
Can also utilize the device in the exit, absorption tower of film device, so that remove residue and other impurity of gas hydro carbons from gas phase, the residue of gas hydro carbons and the molecule of other impurity are different from the molecule of the main gas of determining that aerochemistry is formed.
The use of film device makes and can significantly reduce the discharging that environmentally harmful material enters environment, and if that be desirable economically, provide to the inlet of access to plant and supplied with the gas of rich hydrocarbon so that the possibility of later use.This can realize by the gas of extracting rich hydrocarbon by liquid-gas jetting equipment from film device out.As a result, hydro carbons is returned to device so that reuptake, and has increased the pressure drop in the film device, and this has strengthened separating and purifying the process that supplies to gas phase wherein from the absorption tower.The further optimization of device operation can realize that this can provide best parameter for the operation of film device by extracting rich appropriate hydrocarbon gas out by additional liquid-gas jetting equipment from film device.
As a result, produced the effective ways of removing hydro carbons from steam medium, this method is used to reduce the discharging of the loss of oil product and the gas of removing hydro carbons that minimizing enters environment and other organic compound and environment is not caused damage.
