Abnormally high pressure in sulfuric acid pipeline

2009-02-22View Original

Thread Content

98% sulfuric acid pipeline pipe size 1 inch and a half length 80 meters 40 degrees warm water heating pipe pump lift 30 meters reactor inlet net height 22 meters After the feeding is completed, both the pump outlet valve and the reactor inlet valve are closed. You will find that after a period of time, the pressure in the pipeline rises, and the highest pressure has been seen to be 19 kilograms.: What's the reason? Is it caused by the thermal expansion of sulfuric acid after the pipeline inlet and outlet are closed? Will the pressure reach that high? Everyone is welcome to analyze the reasons
