304/316L/316 Stainless steel metal structured packing for air liquid filter and distillation tower
1. Yuanqiao factory of 250Y structured packing.
Structured packing is one of our core abilities. Over 30 years of experience in development, design, and production of this type of packing makes us your best partner to find the optimum solution for your application.
2. What is the role of structured packing in high vacuum distillation column?
It is a widely used liquid mixture separation operation in industry, widely used in petroleum, chemical, light industry, food, metallurgy and other sectors. Distillation operations are classified in different ways. According to the operation mode can be divided into continuous distillation and intermittent distillation; According to the composition of the mixture, it can be divided into binary distillation and multiple distillation. It can be divided into ordinary distillation and special distillation (including extractive distillation, azeotropic distillation and salt distillation) according to whether the additive in the mixture is added to affect the vapor-liquid balance. If the distillation process is accompanied by distillation, there are two types of chemical reactions called reactive distillation.
3. Hualai factory structured packing types:
Below are the main types we usually make. Each type has two styles, different in the wave clination angle to the axis, 30 degrees (X style) and 45 degrees (Y style). For example, 250Y structured packing, each wave has a 45 degrees angle to the axis, and the neighboring plates' waves are vertical to each other. We can also help make other types such as 450, 252, 452, etc. as per customer request.

5. Yuanqiao factory structured packing cases
They are widely used in private refineries and some pilot projects. I was lucky because he knew a lot about structured packaging and came up with the type he wanted. To be honest, while I know the basic characteristics of each type of packaging and can do some simple calculations on it, it is far from enough to provide professional advice that is appropriate for the entire system.

Structured Packing Advantage
- Its high mass transfer surface area is suitable for close boiling components distillation due to shorter columns.
- Its structured arrangement ensures no channeling of liquid and requires minimum liquid redistribution.
- Due to its very low pressure drop, it is recommended for vacuum distillation systems.
- It has higher vapour load capacity as compared to random packing and trays.
- It provides low liquid hold-up.
