Alteration Of Research On Distillation Column Of Styrene Distillation System

AS-202 ethylbenzene / styrene cycle tower are styrene device to the expansion a key part of the project, not an increase in the high tower, Tower Drive, under the premise of efficiency through the use of structured packing to raise the purpose of separation. On the basis of the feed components of products, product components of the material, top, bottom operating temperature, pressure and the operation of the structured packing, separated by clear and simple method of product distribution and distillation of the , To run of the theory of plate number, thus calculated fill height. And AS-202 tower separation from the detailed analysis of operating conditions.Distillation of styrene distillation system to optimize the process parameters of design, mainly from the perspective of return than the operation and return to temperature, feed temperature, feed composition, and return flow, the top technical parameters such as pressure to adjust , In the design of one of the major problems is to determine theoretical plate number and operation than returning. And styrene distillation column distillation system within the optimal design of the replacement of mainly filler and other pieces in the transformation of the design. This paper for packing and 250 Y-500 Y-filler for research.
