Chlorine liquefaction process and equipment

The liquefaction process of liquid chlorine mainly includes cooling and compression steps. First, gaseous chlorine is compressed using a compressor, and then its temperature is reduced through a cooling system (such as cooling water or refrigerant), thereby liquefying the chlorine. The list of liquid chlorine liquefaction equipment is roughly as follows: 1. Compressor: used to increase the pressure of chlorine gas. 2. Cooling system: includes heat exchangers, cooling towers, etc. 3. Storage tank: Used to store liquefied chlorine. 4. Control system: includes pressure control, temperature control, etc. 5. Safety systems: pressure relief valves, leak detection devices, etc. 6. Piping and valves: Used for the transportation and distribution of chlorine. Ensure that the appropriate safety regulations and procedures are followed during handling, as chlorine is toxic and corrosive. .

What process is generally used to remove water from chlorine before liquefaction?

Dehydrating chlorine before liquefaction is primarily done to prevent system corrosion and improve liquefaction efficiency. Generally, the method of using desiccants for adsorption is used to remove moisture. Common desiccants include sodium sulfate, calcium phosphate, molecular sieves, etc. The specific steps are as follows: 1. Pass chlorine gas through a drying tower containing a desiccant, which can absorb the water vapor in the chlorine gas. 2. The dried chlorine gas then enters the liquefaction system for compression and cooling. Furthermore, the desiccant must be replaced or regenerated regularly to maintain the effectiveness of the drying system. .

For chlorine dehumidification, we use concentrated sulfuric acid in a bubble tower

If sulfuric acid towers are used, how many towers are needed? And eventually, once the sulfuric acid becomes dilute, won’t it need to be replaced? How to handle waste acid

Washing tower (chlorine water, cooling and washing) – Packing tower (the relatively dilute sulfuric acid from the bubble column is used for preliminary drying) – Bubble column (98% concentrated sulfuric acid). For normal dilute sulfuric acid, there is a process of cracking waste sulfuric acid to produce concentrated sulfuric acid for reuse; however, we opt to purchase it directly. After the concentrated sulfuric acid is unloaded, the dilute sulfuric acid is taken away in its original containers

First, chlorine gas is washed to preliminarily remove moisture and cool the electrolytically produced chlorine. It is then dried in a sulfuric acid tower. The dried chlorine gas is subsequently compressed in a compressor; once it reaches the required pressure, it proceeds to the subsequent processing stages. Diluted sulfuric acid can be used in the primary brine treatment section.

It seems that some recycling services completely ignore the specific circumstances of the requester; they simply respond online, or even use AI to do so. This is a completely irresponsible approach. Particularly in the case of chlorine gas recovery, strict professional design is required, taking into account factors such as the requester’s profitability, safety, and costs.
