Description
Technical field
The utility model relates to liquid storage and transport field, refers to especially a kind of for storing and transport the equipment of tetrafluoroethylene.
Background technique
Tetrafluoroethylene, chemical product English name: tetrafluoroethylene, Chinese 2: perfluoroethylene English name 2:TFE, technical specification coding: 77, CASNo.:116-14-3, molecular formula: C2F4 molecular weight: 100.02, fusing point :-142.5 ℃, boiling point :-78.4 ℃, critical temperature: 33.3 ℃, critical pressure: 3.85Mpa, critical density: 572kg/m3, vapor tension in the time of 25 ℃: 3.19Mpa, vapor density: 572kg/m3; Higher than 200 ℃, start pyrolysis.Heat decomposites the toxic gases such as HF.
Airborne explosion limit increases and broadens with pressure, is 11%～46% during 1.0-1.5Mpa.When aerobic exists, easily form unstable explosive superoxide.
TFE chemical property is very active, hydrogenation, hydrohalogenation, amination, nitrated, sulfonation and multiple sulfo group substitution reaction can occur, can be oxidized, peroxidization, copolymerization own can generate dimerization, cyclodimerization body, long-chain polymerization generates teflon, polymerization reaction heat 172kJ/mol; During polymerization easily there is disproportionated reaction in local superheating, the possibility of blasting.Because polymerizing condition is wide in range, there is the possibility very big (under micro amount of oxygen exists, tetrafluoroethylene forms superoxide, and causes spontaneous polymerization) of autohemagglutination; During autohemagglutination, because reaction heat is larger, can not remove in time reaction heat, blast.Need and add under the condition of stabilizer (terpenes or tri-n-butylamine) and store at low temperature, isolated air for this reason.Initator during polymerization can be oxygen, superoxide or variable valency metal oxide; Water can accelerate initiation.
Due to the chemical characteristics of tetrafluoroethylene, under prior art condition, generally do not carry out the storage of long period, more dare not transport; Be all with producing with use, enter next process, tetrafluoroethylene is transformed into other safer material, as hexafluoropropene, teflon etc. at once.
Therefore, do not have in the market tetrafluoroethylene industrial products to sell.
Before, people have solved the explosive issue of TFE in transportation process by HCl being added in the pressurized container of contain TFE.This mixture forms azeotrope, and when TFE evaporates, HCl is also with similar same ratio evaporation like this.When the method has solved this problem of TFE explosion risk, but introduced the problem of other two aspects: when TFE will be for polymerization, must remove a large amount of HCl that TFE exists, and the toxicity problem of taking notice of HCl in outward leakage event.
About memory device, on many parts of patents in the past and periodicals and magazines, all there is detailed introduction, at this, do not enumerate, but these common memory devices can not be for storing tetrafluoroethylene.Application number is
201210169891.4 application documents disclose a kind of low-temperature storage tank, this storage tank can be used in store liquid oxygen,
The cryogenic gas such as liquid nitrogen, liquid argon, but can not be for storing tetrafluoroethylene.Reason is as follows: when tank temperature rises, can cause the increased pressure in storage tank, when being increased to CLV ceiling limit value, must take measures, make the pressure in tank return to safety value, just as the utility model, by gasified refrigerant, temperature is declined, thereby make pressure drop.Liquid oxygen, liquid nitrogen, liquid argon etc. belong to non-toxic gas, itself are exactly refrigeration agent during liquid, need only emptying when pressure raises to atmosphere, and pressure will return to safety value.But the poisonous and harmful hazardous gas of picture tetrafluoroethylene and so on, can not be vented to atmosphere.
