Typical performance of cellulose 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.

The MVR evaporation crystallization system designed by the company has a feed rate of 2.5t/h, an evaporation rate of 2.1t/h, and an electricity consumption of 57KWh/t per ton of water. Compared with the initial design of the three effect evaporation system, it can save 52% of energy consumption. Due to the stable operation of the system and significant energy-saving and emission reduction effects, the enterprise has signed a second phase MVR evaporation crystallization system. The system feed rate is 3.5t/h, the evaporation rate is 3.0t/h, and the electricity consumption per ton of water is 56KWh/t. Compared with the initial design of the three effect evaporation system, it can save 53% of energy consumption.

The system has been running smoothly for three consecutive years, not only solving the problem of meeting the standard for sewage discharge for customers, but also saving a lot of operating costs for customers.
