Description
Technical field
The invention belongs to chemical field more particularly to a kind of dresses based on multiple gases in hydrate recycling catalysis drying gas
It sets and method.
Background technique
Catalysis drying gas is that refinery is the most generally also that a kind of yield (raw material oil quality 5% or so) maximum hydrogen-containing gas is mixed
Object is closed, its main feature is that not only containing a certain amount of hydrogen (volume fraction 15%~40%), but also higher containing economic value
The C such as ethylene, ethane2Component (volume fraction 20%~30% or so), if can be by hydrogen therein and C2Component recycles,
Objective economic benefit can will be brought (it is estimated that the total amount of contained ethylene is super in annual the produced catalysis drying gas in the whole nation to refinery
1,000,000 tons are crossed, and total content and the comparable ethane of ethylene are then the raw materials of best cracking ethylene preparation).For a long time, catalysis is dry
Gas is not utilized well mostly, but is burnt up as device in Gas.Reason is its complicated composition, hydrogen and C2Component

Hydrate separation technology is as a kind of emerging isolation technics, increasingly by attention both domestic and external, with refinery gas
Existing processing technique, which is compared, has unique advantage.Compared with cold separation technology, the condition ratio of hydrate separation technology needs
Relatively mild (pressure is 2~6MPa, and temperature is 0~10 DEG C), can carry out separating-purifying, moderate pressure to gaseous mixture at 0 DEG C or more
Significantly reduce energy consumption；Secondly, compared with adsorption separation technology and membrane separation technique, the scope of application of hydrate separation technology
It is wider, if PSA method and membrane separation process apply in general to the higher unstripped gas of density of hydrogen, the unstripped gas of low concentration is then recycled
Rate is too low, and hydrate separation technology in unstripped gas density of hydrogen it is of less demanding, can generally reach 90% or more return
Yield, and have the pressure loss small, the high advantage of separative efficiency；In addition, hydrate separation technology also have process flow it is short,
The low feature of continuously-running, equipment investment.Hydrate separation technology and traditional absorption, rectifying and adsorption technology also there are many
Single-stage or multistage balance point can be used according to the requirement of separation accuracy in similarity, such as difference that balances each other based on different component
From etc..Therefore hydrate separation technology has good application prospect in terms of the comprehensive utilization of refinery gas.
The existing method or apparatus using hydration method recycling multiple gases is varied, in place of Shortcomings, such as water
It closes object method and other traditional handicrafts combines low separation efficiency；It is excessively single to separate gas；Complex process etc..
