Problems and transformation measures in drainage of rectisol unit
The problems existing in the drainage system during the overhaul of rectisol unit of Guoneng Yulin Chemical Co.,Ltd.were introduced,and the source of solid impurities in the system and the influence on different tower equipment were analyzed.In view of such problems as the complex wastewater transportation process,which was likely to cause the tray blockage of the heat regeneration tower and methanol water separation tower,and reentry of the solid impurities into the system,a pipeline was installed from the outlet valve of the methanol discharge pump to the wastewater delivery level control valve to achieve efficient and safe drainage and avoid the risk of reentry and system blockage of the solid impurities in the wastewater.At the same time,it reduced the power consumption of washing water delivery.
