It’s widely used in many fields because of its low cost compared with other engineering plastics. It’s being instead part of the markets which are traditionally occupied by the metal, and has been one of five major engineering plastics. For China, the research and development of POM is a litter late, the quantity and quality of POM products can not meet the market demand. Compared with foreign advanced level, there is a big shortage. Therefore, It’s is very urgent and important to develop the POM industry of China. Required by a company in northern China, we will design the equipment and piping layouts for the 40kt/a POM plant according the patent bag . 【KEYWORDS】POM；Eqipment layouts；Piping layouts. 目　录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc291434094 1 前言 PAGEREF _Toc291434094 \h 1 HYPERLINK \l _Toc291434095 2 工艺流程 PAGEREF _Toc291434095 \h 2 HYPERLINK \l _Toc291434096 2.1 甲醛浓缩单元 PAGEREF _Toc291434096 \h 2 HYPERLINK \l _Toc291434097 2.2 稀醛回收单元 PAGEREF _Toc291434097 \h 2 HYPERLINK \l _Toc291434099 2.2.1 甲醛的收集 PAGEREF _Toc291434099 \h 2 HYPERLINK \l _Toc291434101 2.2.2 低沸点杂质中分离甲醛 PAGEREF _Toc291434101 \h 2 HYPERLINK \l _Toc291434102 2.2.3 甲醛回收 PAGEREF _Toc291434102 \h 3 HYPERLINK \l _Toc291434103 2.3 单体合成单元 PAGEREF _Toc291434103 \h 3 HYPERLINK \l _Toc291434104 2.3.1 TOX反应 PAGEREF _Toc291434104 \h 3 HYPERLINK \l _Toc291434105 2.3.2 TOX萃取 PAGEREF _Toc
