Abstract
This invention relates to a recovery and utilization method for acid water of a hydrocarbon steam transformation hydrogen-manufacturing device, which drives the acid water from a hydrogen-manufacturing device to an acid vapour extractive tower to carry out vapour extraction, the temperature at the top of the tower is controlled at 95-101deg.C, the bottom temperature is at 97-102deg.C, the pH of the extracted acid water is 6.5-7.5, and the water processed by vapour is boosted by a pump and filtered by a filter to get filtered water then to be cooled to 60-80deg.C to enter into a storage tank, which can reduce pollution and waste of acid water and recover and utilize all of the acid water as the water for heat-conversion and cooling devices or other devices.
Description
Technical field
The invention belongs to the recoverying and utilizing method of a kind of acidic water of hydrocarbon steam conversion hydrogen production plant in the chemical technology field.
Background technology
Water is the precious resources that the mankind depend on for existence, and one of chemical industry industry that to be water consumption bigger, for this reason, along with growing and scientific and technical the advancing by leaps and bounds of chemical industry, seems more and more important for the recycling and the using water wisely of chemical industry institute water.In known technology, the acid water that hydrocarbon steam conversion hydrogen production plant produced in the existing chemical enterprise, mainly be to adopt to be transported to boiler by connecting pipe, becoming boiler recirculated water recycles, but because the acid water of device for producing hydrogen originates in hydrocarbon steam conversion hydrogen production plant, it is acid that its water quality shows.Because acid water has strong corrosivity to equipment, thereby be used for boiler water and add alkali with regard to needs and carry out neutralisation treatment, usually cause behind the alkali the contained sodium ion of boiler water excessive and influence the normal operation of boiler again but add, so, most acid water is to adopt directly to emit, a cover 10,000 Nm
3The hydrocarbon steam conversion hydrogen production plant of/h per hour produces acid water up to more than 5 tons, has so both caused environmental pollution, causes the serious waste of water resource again.
Summary of the invention
In order to overcome the deficiency of prior art, solve the problem that the acid water of hydrocarbon steam conversion hydrogen production plant can not all be recycled effectively, the invention provides a kind of modern design, reduce the pollution and the waste of acid water, the new method that the acid water of hydrocarbon steam conversion hydrogen production plant all can be recycled.
The present invention addresses the above problem the technical scheme that is adopted:
A kind of recoverying and utilizing method of acidic water of hydrocarbon steam conversion hydrogen production plant, design is adopted by soul water stripper output and is connected booster, booster connects filter by water pipe, the outlet of filter connects cooler by water-supply-pipe, the recycle device of the acidic water of hydrocarbon steam conversion hydrogen production plant that the water-supply-pipe connection water tank of cooler is formed, the acid water that hydrocarbon steam conversion hydrogen production plant is come directly enters soul water stripper, soul water stripper adopts water vapour to carry out stripping, the stripping tower top temperature is controlled at 95～101 ℃, 97～102 ℃ of stripping column bottom temperature controls, through acid water behind the stripper stripping between PH 6.5～7.5, after water after stripping is handled boosts with water pump, be filtering water after filtering through filter again, again filtering water is gone into after cooler is cooled to 60～80 ℃, go into water tank, or will filter back filtering water directly enters water tank without cooler, it is heat exchange that the outlet pipe of water tank connects the hydrogenation plant water injection pipe, the water filling of cooling device, or as the water of miscellaneous equipment device.
The recoverying and utilizing method of above-mentioned acidic water of hydrocarbon steam conversion hydrogen production plant, described hydrogenation plant comprises: hydrocracking unit, gasoline, diesel hydro-refining unit, Wax Oil Hydrogenation Unit, oil hydrogenation reaction units such as residual hydrogenation equipment.
The recoverying and utilizing method of above-mentioned acidic water of hydrocarbon steam conversion hydrogen production plant, adopt booster input water pipe to connect the acid water delivery outlet of hydrocarbon steam conversion hydrogen production plant, booster output water pipe connects the heat exchange of hydrogenation plant, the water injection pipe of cooling device, the recycle device of the acidic water of hydrocarbon steam conversion hydrogen production plant of being formed, after the acid water that hydrocarbon steam conversion hydrogen production plant is next boosts with water pump, directly send into hydrogenation plant separately as the heat exchange of hydrogenation plant, the water filling of cooling device, or and other demineralized water, steam condensate or Industrial cleaning facility water mix, as the heat exchange of hydrogenation plant, the water filling of cooling device.
When the present invention uses, connect stripper, water pump, filter at acidic water of hydrocarbon steam conversion hydrogen production plant out splice going splice load water-supply-pipe, acid water is become the filtering demineralized water through stripping, pressurization, filtration, again through the cooler cooling or be delivered directly to the water filling of hydrogenation plant as heat exchange, cooling device.Because the effect of hydrogenation plant cold exchange device water filling is in order to prevent hydrogenation reaction product salt crust on cold exchange device, to have dissolved the apparent strong basicity of sewage of hydrogenation reaction product.Or as the water of miscellaneous equipment device.Or, directly the acid water of hydrocarbon steam conversion hydrogen production plant is connected and be used for the heat exchange of hydrogenation plant, the water filling of cooling device in conjunction with the operation reality of hydrogenation plant.Because the discharge water of hydrogenation plant is alkalescence, is just playing neutralization so directly inject the acid water of hydrocarbon steam conversion hydrogen production plant, thereby greatly reducing the hydrogenation plant externally discharged waste water.
Because the present invention designs and adopted technique scheme, solved the problem that the acid water of hydrocarbon steam conversion hydrogen production plant can not all be recycled effectively.Show through the overtesting result on trial, the present invention compared with prior art, has modern design, can significantly reduce the waste of acid water and the environmental pollution that discharging causes, the acid water of hydrocarbon steam conversion hydrogen production plant all can be reclaimed, be used for the heat exchange of hydrogenation plant, the water filling of cooling device, and the water of miscellaneous equipment, device etc.
