| 摘 要： | 通过对某石化厂催化装置低温余热利用现状进行分析，提出了利用催化装置低温余热的3个有效方案。通过综合比选后得出：将催化装置顶循热作为2号气分装置脱丙烷塔的重沸器热源，替代原来脱丙炕塔重沸器的加热蒸汽，合理地利用了催化装置的一部分余热。剩余热量以热媒水方式供热，直接供给厂内原有热用户、新建溴化锂制冷站和厂内主要办公大楼的夏季空调使用。从而较大的减少了炼厂蒸汽的使用量，减少了全厂循环冷却水的使用，提高了炼厂能源的综舍利用率，提高了炼厂经济效益。

| Abstract: | Three effective programs of utilizing low-temperature waste heat from FCC unit are proposed by analyzing the status of low-temperature waste heat utilization in a petrochemical plant.The comparison results show that substituting top pumparound from FCC unit for heating steam as the heat source for reboiler in depropanizer of No.2 gas separation unit can reasonably utilize part of the waste heat from FCC unit.Surplus heat is directly supplied as heating medium water to the existing heat users in plant,the ne... |
