开发热管技术,回收SO_3余热

Use of Heat Pipe to Recover Waste Heat from SO_3

在140kt/a硫酸装置上,利用热管技术回收三氧化硫气体的中温余热。回收的蒸汽压力为500kPa,蒸发量1.2～1.6t/h。投资的回收年限21个月。

Middle-level heat was recoverd from SO3 with heat pipe to generate 1.2-1.6t/h of steam at 500kPa in a 140kt/a sulphuric acid unit. The return period of the investment is 21 months.
