Heat source issue in the first stage of startup for two-effect falling-film concentration of caustic soda production

2019-07-10View Original

Thread Content

Currently, Bot’s process for producing caustic soda flakes from 50% liquid caustic soda relies on two-effect falling-film concentration. The heat source for the first stage (pre-concentrator) is provided by the secondary gas from the second stage (final concentrator). But when driving the machine for the first time, the second stage has not yet generated enough secondary gas, and the first stage lacks sufficient heat source. Can the product reach 98.5% of the designed concentration at this point, and how should it be controlled?
