摘要
结合某甲醇厂甲醇尾气提氢技术指标,介绍了变压吸附装置的工艺原理;简述了8-1-6 VPSA提氢装置工艺流程、工艺控制点以及自主开发的智能化PLC控制程序在提氢装置的应用情况;提出了提氢工艺的优化措施。结果表明,提氢装置可将氢气纯度提高到99.99%。
In combination of hydrogen extraction technology index for methanol tail gas in a methanol plant, author has introduced the process principle of pressure variation adsorption plant ; has briefly described the process flow of the 8 - 1 - 6 VPSA hydrogen extraction plant, process control point and application situation of self-developed/smart PLC in hydrogen extraction plant ; has presented the optimized measures for hydrogen extraction process. Result indicates that the hydrogen extraction plant can increase hydrogen purity to 99.99%.
