Hydrogenation unit circulating hydrogen desulfurization tower

In the hydrogenation unit’s circulating hydrogen desulfurization tower, the lean liquid refers to the liquid containing sulfides. Hydrogen is used to absorb sulfides from the lean solution. Therefore, the sulfide content in the lean solution is directly related to the amount of hydrogen used. Generally, the ratio between hydrogen and the amount of lean liquid can be determined based on specific process conditions and equipment design. The proportional relationship is usually controlled by setting the flow rate of dissolved hydrogen. In practical operation, reasonable adjustments need to be made based on factors such as the sulfide content of the lean liquid, the required treatment efficiency, and the performance of the equipment. In summary, the ratio between hydrogen and the amount of lean liquid is a dynamic equilibrium process, and adjustments need to be made based on specific circumstances in practical operations. .
