| titleOfInvention | The method of ethanol less energy-consumption Dehydration ethene |
| abstract | The invention describes a kind of method for ethanol feed Dehydration ethene, be included in interchanger, due to the heat exchange with the effluent available from last reactor, evaporate the described ethanol feed mixed with the purified water stream at least partially according to stage f) recirculation, described mixture introduces described evaporation stage under the pressure of 0.1-0.4MPa, compress this evaporating mixture within the compressor, under the inlet pressure of the temperature in of 350-500 DEG C and 0.2-1.3MPa by described evaporation and the mixture of compression introduce at least one and to contain in the adiabatic reactor of at least one dehydration catalyst and in wherein dehydration reaction occurring, effluent available from last adiabatic reactor of stage c) is separated into and comprises pressure lower than the effluent of the ethene of 1MPa and the effluent comprising water, purifying at least partially available from stage d) the effluent comprising water and be separated at least one purified water stream and at least one unconverted ethanol stream, stage upstream a) is recycled to by the purified water stream at least partially available from stage e). |
