2results about How to "Guaranteed desulfurization effect" patented technology

The utility model discloses a multilayer combined filter structure of desulfurization dust remover, including tower body, at least one layer composite filler layer is arranged in the tower body, the composite filler layer is multilayer structure, and the regular shaped filler area, transition flow guide area, bulk packing area and support grating from top to bottom include successively, the regular shaped filler area and bulk packing area outside all are provided with fixed frame, the regular shaped filler area and bulk packing area are filled in the corresponding fixed frame respectively, through the high specific surface area of bulk packing, can effectively strengthen gas liquid contact in bulk packing area, improve mass transfer rate, and the low resistance characteristic of regular shaped filler can avoid partial pressure drop surge in regular shaped filler area, realizes the balance of desulfurization efficiency and energy consumption, reduces operating energy consumption while guaranteeing desulfurization effect.

The invention relates to the technical field of corrosion control of petroleum refining equipment, in particular to a corrosion control system for a recycle hydrogen desulfurization system of a hydrogenation device, which comprises a recycle hydrogen desulfurization system connected with an amine liquid feeding system and used for injecting lean amine liquid to absorb and remove H2S in recycle hydrogen gas; the data acquisition module is used for acquiring process parameters of the recycle hydrogen desulfurization system and sending the process parameters to the data processing module; the data processing module is used for calculating a theoretical amine liquid injection rate according to the process parameters and the corrosion control indexes, and sending the theoretical amine liquid injection rate to the feedback regulation module; the feedback adjusting module is used for controlling the amine liquid feeding system to adjust the lean amine liquid injection amount of the circulating hydrogen desulfurization system in real time according to the theoretical amine liquid injection amount. The theoretical amine liquid injection amount is automatically calculated according to the process parameters and the corrosion control indexes, and the actual injection amount is continuously adjusted through closed-loop control, so that the desulfurization efficiency is improved, and the corrosion risk of the system is effectively controlled.
