Discussion on the latest liquid chlorine production technology

Our company uses a Daleng screw compressor (heat exchange between R22 and chlorine gas) and a liquid chlorine device with an annual output of 20,000 yuan. Now I want to start the second phase. Didn't we say that R22 will no longer be used in 2010? I don't know what the future development will be. I don’t know what the device is like for the liquid chlorine high pressure method? What are the applications of lithium bromide devices? If our company adopts the latter two, it will be difficult to combine them with the first phase. Can any expert help me or provide me with a manufacturer that has installed this device? I'll go take a look. Thank you! # , , &
The high-pressure method is not supported. Our factory currently uses the low-temperature and low-pressure method. The compressor outlet pressure is controlled between 0.15-0.2MPA! This pressure range is also selected based on the compressor outlet pressure. Excessive outlet pressure is not good for the chlorine compressor! The liquefaction temperature is controlled at -20__ -Between 30! If controlled well, the liquefaction efficiency can be controlled between 80% and 85%! It is absolutely impossible to completely liquefy the impurities (hydrogen) that are not easy to liquefy, and are still sent to the tail gas and hydrochloric acid sections. A complete set of refrigeration units is required. If high pressure is used, the investment will be high and the risk will be high! Of course, then you can liquefy the chlorine with water!, eliminating the need for a complete set of refrigeration equipment! It can be determined based on the funds and existing situation of your factory, preferably based on the output capacity of the compressor!
The most commonly used technology now is the low-temperature and low-pressure method, which is safer.
Manufacturers that use the high-pressure method include Liaocheng Lanwei, Dongying Chemical Plant, Jinling Group, Henan Aerospace, Gaomi Oasis and other manufacturers. However, I do not recommend the high-pressure method because the high-pressure liquefaction liquefier is prone to leakage. This post was last edited by liuming31 on 2009-2-8 08:26 ]
Our company uses a low-temperature and low-pressure method. The temperature is generally controlled at -17∽-28℃, and the liquefaction efficiency can be around 80%.
The chlorine gas of the ion membrane can be liquefied at room temperature with 12.5 barA, and the efficiency can reach 92%. What's more, how do you achieve acid vapor crystallization at low temperatures?
