Temperature control performance of the feed temperature control valve in the hydrogen sulfide removal stripping tower
Thread Content
The feed temperature control valve of the hydrogen sulfide removal stripping tower in this unit has never been put into use. This temperature control valve is a cross-line valve located in the shell side of the four heat exchangers used for heat exchange with diesel fuel. I would like to know about the effectiveness of using this control valve in the hydrorefining process, as well as its typical opening degree. My goal is to address the issue of temperature fluctuations after air cooling at the top of the tower. I believe that fluctuations in the feed temperature are also one of the contributing factors, and I hope those with more experience can offer some advice!
Has the temperature control valve installed in your device been put into use? What is the normal opening degree? My plant's processing capacity is 800,000 tons per year, and the distillation system consists of only one hydrogen sulfide removal stripping tower and a distillation tower.
The feed temperature definitely needs to be controlled
