Design of Refine Section for annual output of 80,000 tons acrylic acid technology
Abstract: This design was reviewed the demand of acrylic acid at home and abroad and prospected for its development. Through comparing all kinds of acrylic acid production technology, chose the two steps propylene oxide production of acrylic acid production process, and then through absorption tower preliminary processing of thick acrylic into refining workshop, refining section process adopted three towers, fractionators light components, respectively, to take off the heavy acetate and acrylic acid purification towers. And to deal with waste water and exhaust gas produced, to achieve security environmental protection requirement. Of refining process was simulated by Aspen plus software, at the same time, it is concluded the material balance and energy balance. Through Aspen plus data, carried on the design and equipment selection of the tower of the tower and draw a process flow diagram, the main body figure, take the control points of process flow diagram and workshop equipment layout, etc.
