SS316L Diameter 500mm 250Y Structured Packing Distillation Column

SS316L Diameter 500mm 250Y Structured Distillation Packing

1. Hualai factory of 250Y structured packing.

Hualai factory has produced and deliverd more than 1,000 cubic meters of metal structured packing in the past 3 years. In a separate workshop with lines of brand new machines, we are able to make 20-30 cubic meters of high quality tower packing per working day. 

2. 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.

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.

4. Hualai factory structured packing cases

I have a customer who is a senior engineer in modular refinery system. Their oil and gas processing systems are famous in Russian and Middle Asia market. They are widly used in privately onwed refinery plants and some pilot testing projects. I am lucky because he knows well about the structured packing and has in mind the type wanted. Frankly speaking, though I know some basic features of each type of the packing, and also can do some simple calculation on it, it is far away from enough to provide professional suggestions suitable for the whole system.

During the communication, everything went well except that he questioned the unit weight of our 250Y column packing, that is different from a notable manufacturer. Finally we found out the difference came from the plate thickness. The popular plate thickness for metal structured packing is now 0.1mm, while his data was based on 0.2mm plate. We can fabricate 0.2mm plate tower packing, too. If the flow media is not so corrosive, it is not necessary to choose the thicker plates with higher cost. Will you agree with me please?
