Yuanqiao made 500Y metal sheet structured packing 5000 mm diameter
1. 5000mm diameter 500Y metal sheet structured packing.
When the thin layer of high porosity packing is placed in the large diameter tower, the gas flow distribution on the cross section of the tower is not uniform, which affects the mass transfer efficiency of the packing. At this time, the inlet gas distributor should be set to make the high-speed gas flow in the feed pipe evenly distributed on the cross-sectional area of the tower.

3. Function of metal corrugated plate structured packing in distillation column
Through the packing, the two-phase flow is upward and downward
convection. Gravity is the driving force of liquid flow, and
pressure difference is the driving force of gas flow. The two phase
flow is mass transfer and heat transfer through the two forms of
film surface and spray. The mass transfer and heat transfer of the
two phases in the plate column take place in the gas-liquid mixed
phase on the upper surface of the tray, on the liquid layer surface
of the downcomer and on the bubbling area caused by the mass
transfer elements.
