The level of the reflux tank at the top of the hydrogen sulfide gas tower is unclear
Thread Content
The level of the top reflux tank in the hydrodesulfurization hydrogen gas column for paraffin oil is not clear; on-site inspections sometimes reveal a large amount of black flocculent material in the lower layer, and in some cases the mixture may even be divided into three layers. The valve position remains unchanged, yet the level can fluctuate significantly
Close one valve to drain the medium used for cleaning the level gauge; then open the upper and lower valves again and try to put it into use
The unit has only been in operation for a year; corrosion inhibitor is added to the top of the tower, so corrosion shouldn’t be severe! The outlet valve was closed and the system was vented several times, but the problem persisted. 10 kilograms of superheated steam is being used for blowing; the maximum temperature is 190 degrees, and the pressure is 6.7 kilograms. Is the setup correct? Please give some advice, experts
The tower top temperature is too high; the tower pressure has decreased slightly, so the amount of release agent injected should be increased a bit
