Typical achievements in the fine chemical industry

The MVR evaporation crystallization system for cellulose wastewater with an hourly processing capacity of 2.5 tons designed by the company for a certain chemical technology limited company has been officially put into operation. The main component of the system feed liquid is sodium chloride, which is a weakly alkaline liquid with a COD content of 90000-160000mg/L and a high salt content. The system adopts the method of evaporation concentration crystallization, and the crystallized sodium chloride is sold as a product to achieve the purpose of waste reuse.

According to the properties of ammonium chloride, the system adopts a cooling crystallization method, and the feed liquid is circulated and concentrated in the system. The feed liquid with the standard concentration enters the cooling tank and centrifuge in sequence to separate the salt and mother liquor. The separated mother liquor then enters the system for continuous evaporation and concentration. After a long period of continuous operation, the system has been tested and all specified indicators have met the contract requirements. The feed rate is 4.0t/h, the evaporation rate is 3.42t/h, and the electricity consumption for evaporation per ton of water is 58KWh/t.

Compared to the initial design of the three effect evaporation system, this system can save 50% of energy consumption, effectively ensuring the normal production process of customers, safeguarding their core interests, and truly achieving the goal of energy conservation and emission reduction.
