[Soda Ash Knowledge] Daily Question (168) 3/30/2010

The level of sodium chloride in caustic soda is directly influenced by that in heavy caustic soda, and the control of sodium chloride content in heavy caustic soda is related to its firing rate. Therefore, the control of sodium chloride in heavy caustic soda should be carried out in conjunction with that in soda ash. The main measures include: ① Analyze the sodium chloride content in heavy caustic soda every 15 minutes, and adjust the amount of water used for washing accordingly based on the level of sodium chloride present； ②Regularly check the liquid level in the alkali tank to maintain it at an appropriate level, preventing the alkali from splashing out and causing excessive fluctuations in salt content ； ③Regularly check the water distribution in the alkali filter machine, and eliminate issues such as uneven water distribution due to an uneven tank surface, which can cause large fluctuations in the sodium chloride content in the concentrated alkali; this helps to prevent accidents related to interruptions in the water supply process ； ④When an abrupt increase in sodium chloride content in the caustic solution is detected, in addition to increasing the amount of water used for washing promptly, it is also necessary to check the Cl- content in the wash water. If the Cl- content in the wash water exceeds 1.5 tt, this should be reported immediately, and the cause must be identified. At the same time, the use of wash water should be stopped right away, and soft water should be used instead ； ⑤If, due to the fine crystals of heavy alkali, the heavy alkali after filtration by the alkali filtration machine contains high levels of sodium chloride and moisture, it is necessary to contact the carbonation unit promptly to find a way to address this issue ； ⑥When the sodium chloride content in the cost-effective soda ash approaches the upper limit specified, the amount of water used for washing should be increased promptly to reduce the sodium chloride content in the heavy soda ash ； ⑦When a large amount of heavy alkali is added to the heavy alkali belt station, a sample of soda ash should be taken for analysis to determine the sodium chloride content; based on this value, the sodium chloride content in the heavy alkali used by the alkali filtration machine should be adjusted accordingly.
