Firstly, caustic soda evaporation can utilize a three-effect counter-current evaporation unit to make full use of the energy of steam； Secondly, the temperature of the humid gas discharged from the outlets of the chlorine and hydrogen main pipes is relatively high; it is possible to use this gas to preheat the brine, thereby reducing steam consumption. Again, the condensate water from caustic soda evaporation can be used for desalination, saving steam. Finally, the hydrochloric acid furnace can also be a four-in-one furnace that utilizes by-product steam, enabling efficient use of reaction heat while reducing steam consumption.
Steam condensate is recycled for use in the desalination of brine; it is also used to produce steam in boilers that generate hydrochloric acid as a by-product, and furthermore it is utilized in pure water production facilities to create pure water.
