Background technology
In refining of petroleum industry, the major function of heavy constituent gasoline stripping tower is separation of material component, air lift is a physical process, it adopts a gaseous media destroy Primordial Qi liquid biphase equilibrium and set up a kind of new vapor liquid equilibrium state, a certain component in solution is desorbed because dividing potential drop reduces, thus reaches the object of separate substance.The charging of heavy constituent gasoline stripping tower is hydrogen sulfide containing heavy gasoline components, passes into the steam of about 1.0Mpa at the bottom of tower, improves oil product temperature, reduces oil product dividing potential drop, blows and carry hydrogen sulfide and light hydrocarbon component, reaches the object of producing low-sulfur cleaning product.But in actual production, because steam fluctuation is comparatively large, cause oil product band water, product is muddy, affects quality product.
And in petroleum refining process, the venting port expellant gas of the return tank at stabilizer tower top, its component mainly 60% hydrogen and some dry gas, liquid gas fraction, substantially not sulfur component, and the temperature of its temperature and steam is similar, its pressure is 0.8Mpa, meets the working condition of heavy constituent gasoline stripping tower completely, therefore be necessary to utilize stabilizer tower expellant gas to substitute the production of steam for heavy constituent gasoline stripping tower, to reach the object of improving the quality of products with save energy.The utility model is made based on above-mentioned design philosophy just.
Utility model content
The hydrogen sulfide that the technical problems to be solved in the utility model is to provide a kind of heavy constituent gasoline deviates from device.
In order to solve the problems of the technologies described above, the hydrogen sulfide that the utility model provides a kind of heavy constituent gasoline of following structure deviates from device, comprise heavy constituent gasoline stripping tower and stabilizer tower, the top of stabilizer tower is connected with return tank, and its constructional feature is to be provided with the air feeder venting port expellant gas of return tank can sent in heavy constituent gasoline stripping tower between return tank and stabilizer tower.
Described air feeder comprises the air-supply duct be communicated with bottom return tank venting port and heavy constituent gasoline stripping tower, and air-supply duct is serially connected with the first gate valve, flow measurement device, flow regulation device and the second gate valve successively by apart from return tank venting port order from the close-by examples to those far off.
Described flow regulation device is the electric flow setting device that the flow signal sent according to flow measurement device regulates opening degree size automatically.
Described flow measurement device comprises the 3rd gate valve, thermal type gas quality flow meter and the 4th gate valve that are serially connected successively.
Described flow regulation device comprises the 5th gate valve, electric flow control valve and the 6th gate valve that are serially connected successively.
Described air-supply duct is communicated with the first secondary branch road and ventilating branch road with the second pair that flow regulation device is arranged in parallel of ventilate be arranged in parallel with flow measurement device; First secondary ventilation branch road is serially connected with the 7th gate valve, the second secondary ventilation branch road is serially connected with the 8th gate valve.
Described air-supply duct is serially connected with the gas-holder between the first gate valve and flow measurement device, gas-holder top is provided with vapor pipe, and vapor pipe is serially connected with surplus valve.
The utility model is on the basis of existing heavy constituent gasoline stripping tower and stabilizer tower, the return tank expellant gas at stabilizer tower top sent into heavy constituent gasoline stripping tower and be used for blowing by setting up air feeder and carry hydrogen sulfide and light hydrocarbon component, just can arrive production object, thus structure is simple.
The utility model not only structure is simple, and can bring following beneficial effect.
1, steam saving cost, increases the benefit.The heavy constituent gasoline stripping tower of stable tower top discharge gas per hour needs is not adopted to consume 1.0Mpa steam about 0.8 ton, and the price of steam is approximately 220 yuan/ton, only this estimation, the annual steam cost saved is 0.8 ton × 8000 hours × 220 yuan=1408000 yuan.
2, discharge of wastewater is reduced, protection of the environment.The steam that heavy constituent gasoline stripping tower passes into delivers to sour water treatment system via dissolving partial vulcanization hydrogen after the cooling of tower top air cooler as outside sour water, adds the cost of sour water reprocessing, also may to environment.Adopt and stablize the stripping fluid that tower top discharge gas is then clean and effective, there is not the pollution hidden trouble to environment.
3, air cooling load is reduced, brownout.After adopting the useless hydrogen discharge gas stablizing tower top, the cold load of heavy constituent gasoline stripping tower head space can also be reduced fully, utilize the cold rear temperature of frequency conversion air cooling electric machine control, reach energy-saving and cost-reducing object.
4, reclaim useless hydrogen lighter hydrocarbons, increase yield.Because stable tower top gives up also containing a small amount of liquefied gas component in hydrogen discharge gas, then time inner by heavy constituent gasoline stripping tower, solubilized, in oil product, decreases lighter hydrocarbons emission loss, increases the liquid yield of device.
5, control oil product moisture, ensure the quality of products.Adopt after stablize the useless hydrogen of tower top, effect is exactly that oil product after processing is not moisture the most intuitively, maintains the transparency of oil product, has both been stripped of hydrogen sulfide and has also ensure that cleaning of the quality of product and outward appearance.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail:
Fig. 1 is structural principle schematic diagram of the present utility model.
Embodiment
