200000 Tons Ethanol Dehydration System Ethanol Production Plant

200000 Tons Ethanol Dehydration System Ethanol Production Plant

Changchun Jiliang Tianyu 200,000 Tons Ethanol Dehydration System

Technology Application:

The new technology of dehydration with variable temperature and pressure(FTrPSA)is adopted, featuring in low energy consumption (each ton of ethanol products only consumes 0.1 ton od steam), High purity( the concentration of the ethanol products can exceed 99.995%) And high yield(The compared membrane separation method is of higher yield), And the dehydrated molecular sieve is the OEM designated by DAVY technology of UK, and the technology and devices are sold overseas.

Process discription

95% (w / w%) ethanol raw material from outside the battery limit is sent to the superheater. The temperature of ethanol steam entering the tower is controlled by strictly adjusting the flow rate of heating steam, so as to ensure that the quality of ethanol steam entering the molecular sieve adsorption tower fully meets the feeding conditions.

Molecular sieve adsorption tower group is composed of a group of adsorption tower and program-controlled valve with regulating function, and its working process is completely carried out automatically according to the set sequence. The qualified ethanol steam enters the adsorption tower through the program-controlled valve at the inlet of the adsorption tower for dehydration (there are two towers in each period of time for adsorption). The dehydrated product (water content ≤ 0.02%) is sent out of the battery limit after pressure control.

Technical indexes:

Purity : ≥99.995%

Capacity: 100~60000kg/h

Yield : ≥80%
