Beijing Soonjet Technologies Co. Ltd began to develop the Micro Tube Demister (MTD) in 2022. After going through theoretical research, computer simulation analysis, small-scale tests, and on-site tests at thermal power plants, it now has the conditions for batch production. In 2024, it has been applied in engineering. The invention patent for this technology has been authorized.

The Micro Tube Demister (MTD) is short for Micro-Tubes dust and mist eliminator. Because the separation efficiency is greatly improved, it can greatly reduce pollutant emissions (by 50% to 80%), save energy consumption in the purification process (by 50% to 80%), and at the same time, it also has technical and economic advantages such as easy to be clean, occupying less space, and having low comprehensive cost. It can solve problems such as : high particulate matter emission concentration, large airflow resistance, fouling of the demister, large maintenance workload, and chimney rain caused by the demister.

On March 3, 2024, the micro tube demister for spray drying exhaust gas purification spray tower of a chemical plant was put into operation.

The application of micro tube demister shows that:
In the case of high concentration of imported particulate matter, no obvious dirt or blockage risk is observed;
The airflow resistance is about 50Pa;
The concentration of exported particulate matter is very low;
Operation stable and reliable .

The benefits that micro tube demister can bring to customers:

For engineering companies that use micro tube demister:

1. Lower purchase cost of demister;
2. Reduce the height of the desulfurization tower and lower the cost of supporting facilities;
3. It is easier to achieve the standard of outlet particulate matter concentration, with less probability (time) of exceeding the standard;
4. Provide lower operating cost solutions to end customers and enhance customer satisfaction.

For end customers who use micro tube demister:

1. Less particulate matter emissions and less probability (time) of exceeding standards.
2. The total cost of purchasing micro tube demister or desulfurization projects is lower;
3. Low operating energy consumption and significant energy-saving benefits (the investment payback period for the renovation of the four level tube bundle demister is 2-3 years);
4. Easy to clean and reduce maintenance works.
