Description
Technical field
The utility model is related to a kind of high-pressure separator, and in particular to a kind of high-purity alkane of the refined production of petroleum naphtha hydrogenation and
Solvent high pressure hot separator.
Background technology
With environmental protection and the raising of oil product standard, whether product oil, or petrochemical materials product, to product or original
The sulfur content control of material is increasingly harsh.In order to reach the requirement of desulfurization environmental protection, most oil product and petrochemical materials manufacturers
Hydrofinishing is carried out to product in process of production.Hydrofining technology is that various petroleum distillates are carried out under certain hydrogen pressure
One general designation of catalytic reforming.It refers in certain temperature and pressure, have existing for catalyst and hydrogen under the conditions of, make raw material
In all kinds of non-hydrocarbon compounds occur hydrogenolysis, generation sulfide, ammonia, water and other faint products, and then from oil product or stone
Change and removed in raw material, to reach the purpose of refined oil or petrochemical material.
Hydrofining technology is carried out under conditions of hydrogen-rich, and reactor, which goes out, also has a large amount of unreacteds in reactant
Hydrogen, Hydrogen Separation more than needed need to out be recycled by high pressure hot separator.Different process conditions are anti-to being hydrogenated with
Answering the dehydrogenation flow of thing also has difference, and the requirement to equipment is also different.The restructuring more than 200-300 DEG C of usual end point temperature
Divide without high pressure hot separator, fractionating system is directly entered after heat exchange, reduce plant energy consumption；End point temperature is less than
200-300 DEG C of components enter back into high pressure hot separator, cold high pressure separator carries out air-liquid, water separation, and the gas phase isolated is also
Circulation hydrogen system can be just entered back into by desulfurization process is qualified, this technique is to the requirement of high pressure hot separator gas phase separation accuracy
Low, wastewater flow rate is big, the exceeded environmentally friendly risk of waste water be present, the monomer alkane being not suitable for use in below 200 DEG C of the end point of distillation of production
And solvent product.Production 200 DEG C of the end point of distillation below monomer alkane and solvent product during, in order to reduce waste water and its
Its waste production, hydrogenation reaction thing first pass through zinc oxide or carbonoxide adsorptive reactor before high pressure hot separator is entered, and adsorb
Sulfide, ammonia, water and the other faint products that hydrogenation reaction is generated, then isolate hydrogen into high-pressure separator through heat exchange and enter
Circulate hydrogen system, reactant no longer enters cold high pressure separator and directly enters stabilizer, by the dissolved hydrogen in liquid phase, sulfide, ammonia,
Water and the further separated of other gas phase compositions, to ensure that product property is stable.Sulfide, ammonia, water are removed by adsorbing
Although high etc. cost a little do not produce waste water, significant for clean manufacturing, meet environmental protection policy requirement.Due to anti-
The hydrogen for answering thing to be isolated from high-pressure separator is no longer directly entered circulation hydrogen system through desulfurization and other PROCESS FOR TREATMENTs, for
The manual dexterity of high pressure hot separator, separation accuracy, separative efficiency it is also proposed the high requirement of comparison, it is necessary to strict control point
Oxygen, carbon monoxide, carbon dioxide, methane, moisture, hydrogen sulfide, ammonia and the other light component contents in hydrogen are separated out, is followed with reaching
Ring hydrogen system feed needs.So in separator design application above the rule of conventional high-tension separator can not be followed again, and answer pin
Process optimization requirement, reactant property and environmental requirement etc. are upgraded, optimized.
Most of high-pressure separators are designed as horizontal type structure, and stroke of the oil gas reactant in device is short, and reactant flows naturally
Dynamic mixing time length, oil-gas separation efficiency is low, influences gas phase removal efficiency and precision, simultaneously because the electrical components used in the past
Accuracy of detection and poor sensitivity, for the liquid level in device, temperature, pressure change response delay, influence liquid level, pressure, temperature and adjust
Section, operating flexibility is small, cause separate gas phase purity it is low, band liquid the problems such as.In order to solve the problems, such as that horizontal high-pressure separator is present,
Now to be changed to vertical, compared to horizontal separator, gas phase removal efficiency and precision has been lifted more, but also without changing oil gas
Reactant is by the mode of nature flowing stirring, and filler, foam removal design fall behind, poor for changeable adaptability for working condition, in operation bullet
Property, separation accuracy, band liquid etc. needs further to be lifted.
