Main approaches: 1. Ensure the airtightness of the accident tower system; 2. Reduce the generation of waste chlorine
Control of waste discharge volume – It is acceptable to use a slightly lower purity material during operation; it can be sent for liquefaction. Improve the integrity of equipment and pipelines, and try to minimize evacuations\
Make every effort to ensure the normal operation of the equipment and reduce the number of start-up and shutdown cycles (start-up and shutdown processes generate considerable amounts of hazardous chlorine gas). Maintain a proper balance of chlorine usage in processes that involve liquid chlorine and hydrochloric acid, keep pressure stable, and prevent the release of chlorine in case of an accident.

Design the liquid chlorine packaging process in such a way as to reduce the amount of liquid chlorine in the pipes during packaging. 4. Decompose chlorates to produce chlorine, which is then incorporated into the main chlorine pipeline
Minimize the number of start-up and shutdown cycles to ensure stable operation; control the generation of waste chlorine； Follow strict procedures to reduce the amount of liquid chlorine recovered during filling
There are the following ways to reduce the production of hyposodium: 1. Increase the production of hydrochloric acid； 2. Try to improve the liquefaction efficiency ； 3. Optimization of the filling process to reduce waste chlorine emissions to the waste gas treatment system ； 4. After the chlorate decomposes, chlorine does not enter the exhaust gas system but goes directly to the chlorine main pipe and similar components.
The safe operation of the equipment on a regular basis, periodic inspection of devices such as safety valves, timely connection of the chlorine system during startup and shutdown, weekly discharge operations of NCL3, and whether thorough cleanup of liquid chlorine is carried out during maintenance periods
Reply to 1# wenyuyu: 1. Reduce the number of start-up and shutdown cycles in order to decrease the amount of waste chlorine gas； 2. With good sales of hydrochloric acid, producing as much of it as possible can also help reduce the amount of waste chlorine gas ； 3. Improve liquefaction efficiency.
Reply 10# djraul1984: It has nothing to do with the liquefaction efficiency, right? The liquefaction exhaust gas is used for synthesis.
