Light hydrocarbon recovery unit
The light hydrocarbon recovery unit adopts mature and reliable process technology to centrally treat the gas and primary gasoline from the four atmospheric and vacuum distillation units. The dry gas desulfurization section includes feed gas desulfurization tower, methane desorption tower, depropanizing tower, C4/C5 separation tower, LPG desulfurization tower, carbon dioxide absorption tower, solvent regeneration tower, absorption tower, desorption tower, stabilizer, etc., including packed tower and plate tower, mainly plate tower. The main internal components involved include metal bulk packing, liquid distributor, liquid collector, packed grid, packed grid support Tray assembly (float valve, tray plate, downcomer, receiving tray, liquid seal tray and corresponding support beam), oil collecting tank, gas-liquid feed distributor, distribution pipe, bolts, nuts, clips, washers and other fasteners.
● Main tray assembly
(1) Single and double overflow trays - single overflow tray/double overflow tray
(2) Combined guide float valve
