Description
Technical field
The invention belongs to technical field of chemical engineering, relate to organic macromolecule gas and inorganic molecules separation of gaseous mixture, specially refer to the separation method of dichloroethanes and nitrogen in the chlorine industry.
Technical background
In the chlor-alkali plant of petroleum chemical industry, produce in the process of PVC at present, the storage and the transmission that have a large amount of intermediate product dichloroethanes are used.Therefore all be to seal dichloroethanes on the technology, can produce a large amount of by the saturated nitrogen of dichloroethanes with nitrogen.Industrially do not do recycling, therefore caused the waste of atmosphere pollution and resource usually with its direct emptying.
Reclaim the adoptable technology of dichloroethanes from separating of dichloroethanes and nitrogen mixture and mainly contain condensation separation method, absorption process, absorption method.
The condensation separation method is with the gaseous mixture condensation liquefaction that pressurizes, and utilizes rectifying that nitrogen is separated with dichloroethanes again.Because the boiling point of nitrogen is-195.8 ℃, the boiling point of dichloroethanes is 83.4 ℃, need high pressure and low temperature as if the mixture liquefaction with both, so its energy consumption is very high, and equipment investment is big, and economic benefit is low.
Absorption process is that employing tetrachloroization two carbon or trichloropropane are absorbent, absorbs dichloroethanes at low temperatures, resolves through high temperature and reclaims dichloroethanes.The absorbent of this technology source difficulty, energy waste is also very serious, and the nitrogen in the tail gas also takes away certain solvent, thereby causes new pollution.Therefore this The Application of Technology also is restricted.
Absorption method is that employing is an adsorbent to active carbon or the NACF that dichloroethanes has very high selection absorption property, adsorbs dichloroethanes at low temperatures, inhales the residual air nitrogen purge.When adsorbent bed reaches capacity, reclaim dichloroethanes through the high temperature desorb.Environment measuring center, Nanjing is an adsorbent with active carbon, micro-dichloroethanes in the enriched air By, and tetrachloro-ethylene, organic pollutions such as bromic ether have been obtained good effect.But because the concentration of dichloroethanes is about 20% (mol) in the dichloroethanes storage tank breathing gas of vinyl chloride workshop, adopt absorption method to reclaim dichloroethanes, certainly will need a large amount of adsorbents, cause equipment volume huge, high temperature desorption energy consumption height, the cooling difficulty has restricted industrial applications.
Summary of the invention
The purpose of this invention is to provide a kind of membrane separating method that just can separate dichloroethanes and nitrogen at normal temperatures, utilize this method to prepare a kind of zeolite molecular sieve film with special pore size distribution, this zeolite membrane has selective absorption to polar gas, make organic macromolecule gas in its hole, capillary condensation take place simultaneously, and then stop inorganic molecules gas to pass through, realize the separation of mist.
Key of the present invention is to synthesize the NaY zeolite molecular sieve film.Realize that technical scheme of the present invention is, according to Na
