The benzene extracted by the device contains water
Thread Content
Dear colleagues: Our unit’s benzene extraction system is of the extraction distillation type, and it is a single-benzene extraction unit. The benzene product produced currently contains around 700 ppm of water. Do you have any effective methods to reduce this water content?
Is the reboiler leaking? Is the raw material high in water content?
We require the indicator to be kept below 400.
The reboiler is in normal condition; the raw material specifications have not been analyzed yet.
Is it the moisture in the raw material? There’s little else to do but to enhance dehydration; once water enters the tower, it is miscible with the solvent, and without removing that water, the solvent won’t work properly
Which refinery are you from? How can it be that high? What are the operating conditions for your recovery tower?
