本发明提出了一种合理利用变换生产过程中余热的工艺方法,适用于变换气生产的节能设计改造,目的是减少向外界输出的变换气生产过程余热,采用热泵技术将变换气所含低品位余热转换成变换反应所需的较高品位的热能,减少由外界输入这部分能量。方法是采用升温型化学类热泵,将变换气的低品位热能引入热泵,再利用热泵多次加热所需的热水,使变换过程余热得到有效的利
The invention proposes a reasonable utilization of the process technology for converting waste heat in the production process, which is suitable for the energy-saving design and transformation of the shift gas production with the aim of reducing the residual heat in the shift gas production process output to the outside and adopting the heat pump technology to convert the low- The waste heat is converted into higher-grade heat required for the shift reaction, reducing the amount of energy input from the outside. The method is to use a temperature-rising type chemical heat pump to introduce the low-grade heat energy of the shift gas into the heat pump and then to repeatedly heat the required hot water by the heat pump so that the waste heat in the conversion process is effectively utilized
