Problems with the alkylation deisobutane tower
Thread Content
The purity of isobutane cannot be increased in the deisobutane tower; the pressure is 5.8 kilograms, the temperature at the bottom of the tower is 126 degrees, the feed volume is 122 cubic meters, and the reflux volume is 90 cubic meters. The gauge readings are not very accurate – could it be due to overloading? The current purity is around 69%. The temperature differences are quite large during the white nights. Please explain this to me, expert
The temperature at the bottom of the tower is too low; it should be around 155 degrees. Your reflux ratio is too low
What is the liquid level at the bottom of the tower? Has there been a significant increase in the steam consumption of the reboiler?
It must be overloaded; there is a designed capacity.
