May I ask, for 400,000 tons of PVC and 360,000 tons of caustic soda, what is the amount of liquid chlorine that needs to be produced, given the hydrogen-chlorine ratio?

The capacity of the liquefaction plant is designed for an annual output of 80,000 tons; the packaging volume will depend on your sales volume of liquid chlorine
This amount of liquid chlorine produced is the amount that must be produced
A relatively conservative estimate is 0.88 tons of chlorine per ton of caustic soda (100%)； Approximately 0.65 tons of chlorine are required per ton of PVC. Let’s do the calculation.
I think it should be determined based on your hydrochloric acid production capacity; (the only uses for chlorine are in hydrochloric acid or in liquid form), and I suggest that the production capacity for the liquid form should be around 180,000 tons.
For 400,000 tons of PVC, 40X0.57 million tons of HCL is theoretically required; in practice, 40X0.64 million tons of HCL is needed (on a 100% basis). The 96% purity level that you achieve is relatively high, so the coefficient might be lower than 0.64, but this can still be used as an estimate. 40X0.64X36.5/35.5 = 249,000 tons of chlorine are required. 360,000 tons of caustic soda are needed to produce chlorine; 36X71/80 = 319,500 tons of chlorine can be generated. Theoretically, 319,500 – 249,000 = 70,500 tons of liquid chlorine can be obtained, but this amount cannot be achieved in practice. There is consumption during the production process.
Reply to 2# Li Cheng: Why was it designed with a capacity of 80,000 tons? Is that not too large?
Based on a ratio of 1.1:1, the remaining amount of chlorine is 32,400 tons; you can install 2 sets of liquefaction units with a capacity of 20,000 tons each.
Reply to 7# wenyuyu: The design scale for liquefaction is determined based on the chlorine balance and extreme accident scenarios; it is unrelated to the production volume
