一. 工艺流程设计的目的和任务
目的：用图解形式来表达整个生产工艺过程
任务：（1）确定生产工艺流程中各个过程的 具体内容、顺序和组织形式。
（2）绘制工艺流程图。
Stream 15 is then distilled in T-102 to separate acrolein and propylene from water and acrylic acid. The bottoms (Stream16) consisting of wastewater and acrylic acid are sent to waste treatment. The distillate (Stream 17) is sent to T-103 where propylene is separated from acrolein and the remaining water in the system. The distillate from T-103, contains 98.4% propylene. The possibility of recycling this stream can be investigated. The bottoms (Stream 19) is then sent to T-ห้องสมุดไป่ตู้04 where acrolein is separated from water. Stream 21 is sent to waste treatment, and the distillate (Stream 20) consists of 98% pure acrolein.

Propylene (Stream 2), steam (Stream 4),and compressed air (Stream 6) are mixed and heated to 150 ºC. The resultant stream (Stream 8) is sent to a catalytic packed bed reactor where propylene and oxygen react to form acrolein. The reactor effluent is quickly quenched to 50 ºC with deionized water (Stream 13) to avoid further homogeneous oxidation reactions. Stream 12 is then sent to an absorber, T-101, where it is scrubbed with water and acrolein is recovered in the bottoms (Stream 15). The off gas, Stream 14, is sent to an incinerator for combustion.
