【摘要】：最近几年全国灰霾天气出现频率日益增多,研究发现燃煤污染是造成PM2.5升高,以及国内灰霾天气的主要原因。为了降低污染,我国高能耗、高污染的燃气行业,目前正在由以煤为原料的生产方式向以天然气、液化气等清洁型能源为原料的生产方式转变,在目前的过渡期内,采用天然气改质技术将天然气转化为煤气是一种常用的技术。本文在当前煤气厂原有天然气改质生产系统的基础上,设计了一套天然气改质分析控制系统,利用生产过程中的上下文信息,提出了多条控制推理规则。给出了工艺参数的改进方法,克服了人工操作时因为放入过量的空气和水蒸汽而造成的能源浪费现象。在实际生产中取得了良好的效果,实现了增加天然气转化率,节约能源的目标。
[Abstract]:The frequency of haze has increased in recent years across the country, and research has found that coal pollution is the main cause of the rise in PM2.5 and haze in China. In order to reduce pollution, the gas industry with high energy consumption and high pollution in our country is changing from the mode of production of coal as raw material to the mode of production of clean energy such as natural gas, liquefied gas and so on. During the current transition period, It is a common technology to transform natural gas into gas by using natural gas upgrading technology. On the basis of the existing natural gas upgrading production system in the current gas plant, a set of natural gas upgrading analysis and control system is designed. Using the context information in the production process, several control inference rules are put forward. The improvement method of process parameters is given to overcome the energy waste caused by excessive air and water vapor in manual operation. Good results have been achieved in actual production, and the goal of increasing natural gas conversion and saving energy has been realized.
