一、前言搞好重油制气厂的热能利用,是提高重油制气设计和生产技术水平的重要课题,而其中的一个重要方面就是实现工艺余热的最大限度地回收和利用。在回收和利用余热时,应考虑的几个因素是: 1.要有足够可供回收的余热量,以保证它的经济合理; 2.查清工艺各部位排入大气和冷却水及其它物料中的余热量,以及工艺各部位需用量 I. INTRODUCTION The use of heat energy in heavy oil gas plants is an important issue for improving the design and production technology of heavy oil gas production. One of the important aspects is to realize the maximum recovery and utilization of waste heat from the process. Several factors that should be taken into account when recovering and utilizing waste heat are: 1. There must be sufficient residual heat for recovery to ensure that it is economically reasonable; 2. Check out the various parts of the process that discharge into the atmosphere and the cooling water and other materials The remaining heat in the process, and the amount of process needs
