Chemical production involves a complex series of processes, from heating, cooling and condensing to evaporation and separation.  

Sulfuric acid cooling: chemical applications

In the sulfuric acid production system, Propellent plate heat exchangers are used in the dilute sulfuric acid purification section, using two PLD65/133/PLD72/254SMO/E plate exchanges for the dilute sulfuric acid cooling process, and 50 degrees dilute sulfuric acid Cooled to 33 degrees, this process section requires high heat exchange efficiency and corrosion resistance requirements of the plate heat exchanger. Compared with the use of traditional anode protection devices (equivalent to tube heat exchangers), the use of Puripler plate heat exchangers can not only ensure the heat exchange efficiency and the corrosion of the sulfuric acid medium to the equipment to a minimum, but also greatly reduce the cost And operation and maintenance costs.

Chloride production process

In chloride production for cooling process. Methyl chloride cools sulfuric acid at 20 or 25°C; water at 32°C cools lye at 50°C, which plays a role in comprehensive energy utilization and recovery. In the design process, we fully considered that the hot side medium sulfuric acid and lye respectively contained a small amount of methane chloride, sodium chloride, sodium hypochlorite and other small amounts of chloride. The selected heat exchanger uses Hastelloy and fluorine rubber gaskets. The PLK100 and PLD65 heat exchangers used this time have the characteristics of high heat exchange efficiency,

Corrosion resistant plate heat exchanger.
