3.5Y AISI 304 metal plate structured packing 486 mm in diameter
1. Manufacturing requirements of Hualai metal plate structured packing
1.1 According to the requirements, punching, rolling fine grain (or rolling grain equivalent to fine grain) and corrugation of raw stainless steel belt shall be made into corrugation belt of orifice plate, and then the corrugation plate shall be cut into pieces according to different chord length on the cross section of packing plate and the requirements of packing plate assembly or block assembly.
1.2 The packing plate is composed of a number of corrugated plates arranged vertically and evenly. The corrugation angle of the two adjacent orifice plates is overlapped in the opposite direction.
2. Performance index of tray column and packed tower

4. What is the role of structured packing in high vacuum distillation column?
Distillation is a method to separate liquid mixture with high
purity by using reflux. It is a widely used liquid mixture
separation operation in industry, and is widely used in petroleum,
chemical, light industry, food, metallurgy and other departments.
Distillation operation is classified according to different
methods. According to the operation mode, it can be divided into
continuous distillation and batch distillation; according to the
composition of the mixture, it can be divided into binary
distillation and multi-component distillation; according to whether
the additives affecting the vapor-liquid equilibrium are added to
the mixture, it can be divided into ordinary distillation and
special distillation (including extractive distillation, azeotropic
distillation and salt-adding distillation); if the distillation
process is accompanied by distillation, it can be divided into two
types Chemical reaction is called reactive distillation
In the operation of packed tower, the liquid drops from top to
bottom along the structured packing surface, and the rising vapor
contacts with each other. Therefore, the packing surface is the
place for mass exchange and heat exchange.
In Hualai, every year we manufacture and supply hundreds of cubic meters of metal structured packing in different models. There are many popular types and materials for option. Custom order is welcome, too! We are happy to help with what you need!
