年产330吨丙酮酸乙酯车间工艺设计.docxVIP

摘要

本设计为年产330吨丙酮酸乙酯车间工艺设计。丙酮酸乙酯通常情况下是一种无色透明液体，是重要的有机合成体，广泛应用于医药、农药、化妆品等领域。丙酮酸乙酯工艺主要有：丙酮酸和乙醇醇化法、乳酸乙酯氧化法和有机金属试剂催化法等。

本设计采用间歇式生产丙酮酸乙酯。原理是原料在催化剂的作用下，乳酸乙酯进行氧化反应生成丙酮酸乙酯。生产工艺包括：氧化-过滤-蒸馏-水洗-干燥-精馏六个工序。此工艺关键在于催化剂的选用，通过选择负载型钒磷氧（VPO）作为催化剂，过氧化氢作为氧化剂氧化乳酸乙酯得到产品，是一种绿色、高效的合成方法。本设计进行了生产方案比较、工艺流程设计、物料衡算、热量衡算、车间布置设计和对主要工艺设备计算并选型等。通过合理的计算，从而确定了车间与设备的具体设计参数，同时绘制了符合设计要求的CAD图纸，制定车间布局、厂区安排及安全规范，最后对此项目进行了成本和利润估算。
