Technical field

The invention belongs to lighter hydrocarbons dehydration technique fields, and in particular to a kind of method that carbon four is dehydrated after ether.

Background technique

Large chemical complex is to consider economy at present, can be first with the first in carbon four after MTBE device water extraction and separation ether Alcohol, then further deep processing is carried out to carbon four after ether, four deep processing of carbon is for producing dipropyl enanthol after typical ether.But Carbon four has to be lower than 10ppm wt as the raw material water number of further deep processing downstream unit after ether, and carbon four after ether after water extraction Water content generally can be more than 1800ppm wt, four dehydration technique of carbon is not able to satisfy above-mentioned requirements after existing ether.

Summary of the invention

The object of the present invention is to provide the methods that carbon four after a kind of ether is dehydrated, and can be effectively reduced after water ether extracted Four water content of carbon is to 10ppm wt or less.

The technical scheme adopted by the invention is that: a kind of method that carbon four is dehydrated after ether is specifically implemented according to the following steps:

Carbon four is input in freezing unit and carries out sub-cooled processing after the first step, Jiang Jingshui ether extracted；

Second step carbon four will be input in coalescer after sub-cooled treated ether and carry out elutriation and go out to handle；

Third step will carry out carbon four after elutriation goes out treated ether and be input in molecular sieve device to carry out moisture through coalescer Sub- adsorption treatment obtains water content carbon four after 10ppm wt ether below.

The features of the present invention also characterized in that

Freezing unit in the first step include including sequentially connected refrigerant fluid reservoir, evaporator, Spiral Lobe Refrigeration Compressor, Oil eliminator, the tail end of oil eliminator are connected separately with refrigerant cooler, lube oil cooler, the tail end of refrigerant cooler with it is cold The import of matchmaker's fluid reservoir connects, and for recycling refrigerant, the tail end of lube oil cooler is compressed by grease pump and screw bolt refrigerant The import of machine connects, and for recycling lubricating oil, wherein four, carbon process evaporators carry out sub-cooled processing after ether.

The outlet temperature of freezing unit in the first step is set as 9~13 DEG C.

Coalescer in second step is for the quite cohesion of the model PhaseSep LCS4H1AH of your filter company production Coalescer.

The liquid level in coalescer in second step is set as 10~20%.

The pressure of molecular sieve device in third step is set as 2.0~2.2MPa.

The beneficial effect for the method that carbon four is dehydrated after a kind of ether of the present invention is:

The method that carbon four is dehydrated after a kind of ether of the present invention, by successively by carbon four after ether be input to freezing unit, coalescer, In molecular sieve device, the water content after ether in carbon four can successively be reduced, finally in molecular sieve device by after ether in carbon four it is more Remaining elutriation goes out to be discharged, and finally four water content of carbon after ether can be reduced to 10ppm wt hereinafter, this method step is simple and efficient.

Specific embodiment
