The cooling circulation system is used to collect the non-condensable tail gas in the distillation s
Most rectification towers are two-stage condensation. The first stage uses cooling water, mainly condensing the top steam, and the second stage uses chilled water or ethylene glycol, which is mainly used to treat tail gas and remove a small amount of light components. The exhaust gas is condensed. Therefore, the secondary condensation is very small.
Generally, a rectification tower (especially in the case of non-condensable gas, such as a vacuum tower, an atmospheric tower with gas dissolved in the feed, etc.), a two-stage condenser is placed on the top of the tower, and the first stage is cooled by cooling water. Part of the top steam is condensed, and the second stage adopts chilled water cooling to condense the light components in the tail gas as much as possible to reduce material loss. The reason for this is that the operating cost of chilled water is much greater than that of circulating chilled water, so it can be used as little as possible. The primary cooler uses cooling water to condense most of the easily condensable media, and the secondary cooler uses chilled water to condense the remaining small part of the exhaust gas that is not easy to condense. This can reduce the use of chilled water and save energy.
Distillation device, the device is divided into two stages of distillation, the first stage distillation condenser uses cooling water for condensation, while the second stage uses chilled water for condensation. The first stage adopts cooling water cooling to condense most of the top steam, and the second stage adopts chilled water cooling to recover the light components in the tail gas as much as possible to reduce material loss. The light components of the two stages are the same, but the amount of steam from the top of the second stage is smaller than that of the first stage. What is the difference between using chilled water to condense and chilled water to condense? Why do the primary and secondary condensers use different cold media for condensation?
Cooling water is circulating water, the temperature is generally 32-40 degrees. Low cost, easy to use, economical. Chilled water is low-temperature water produced by a low-temperature system. The temperature is generally below 20 degrees, and there are many grades to choose from. Chilled brine is relatively expensive, so the primary cooling will condense a lot of steam, and the secondary will condense the remaining steam.
For the recovery of non-condensable tail gas components in the distillation system, cooling water and chilled water are indispensable, but this also invisibly increases the consumption of resources. The role of one or more water cooling systems is particularly important. The LNEYA cooling cycle system adopts secondary subcooling, which has a fast cooling speed, safe and reliable, and is used for rapid liquid cooling. It is widely used in petrochemical, medical, pharmaceutical, biochemical, freeze-drying, pharmaceutical, military and other high-tech industries. In order to save water resources, ethylene glycol-water mixture can be used for circulating refrigeration, and the circulation pipeline design is strictly designed to prevent circulating water pollution and extend the use time of circulating water.
February 6, 2021If you need equipment to distill CBD, you need to scrutinize your choices, as the equipment can vary in its features and design. When you use equipment that produces a CBD distillate, you want to seek out a system made by a manufacturer that provides proven and reliable products. You should also work with a business that can train you on the use of the equipment you buy.view
