Water Absorption Tower

Application field：

   Widely used in the field of industrial waste gas treatment, especially in the removal of harmful gases such as sulfur dioxide (SO2), nitrogen oxides (NOx), and fluorides;

   In industries such as petrochemicals, chemicals, and electricity, water absorption towers are used to treat harmful substances such as hydrogen sulfide and ammonia in exhaust gases, achieving purification and emission of exhaust gases;

   It is also used to treat volatile organic compounds (VOCs), converting harmful substances in exhaust gases into harmless substances through physical absorption process.

Equipment Advantage：

   The system is equipped with a secondary water absorption unit to ensure that the exhaust emissions meet the standard. In order to manage the use and replenishment of water, the system has a pure water tank equipped with liquid level monitoring and solenoid valves, which can automatically control the replenishment and stoppage of water, and is equipped with a replenishment pump. Each water absorption unit is equipped with an independent absorption liquid circulation pump, designed with a magnetic pump, and the discharge pump also uses a magnetic pump to ensure reliable operation;

   The tower kettle is equipped with an online monitoring system for absorbing liquid concentration, which facilitates real-time monitoring and adjustment. The overcurrent components of the entire system are made of 304 stainless steel to ensure durability and corrosion resistance. The absorption tower uses wire mesh corrugated high-efficiency packing to improve absorption efficiency and prevent liquid flooding inside the tower;

   The system is also equipped with ladders and maintenance platforms for easy operation and maintenance. During the construction period, high tower embedded parts will be provided and pre embedded work will be completed in advance in cooperation with the customer. The fresh water inlet is located below the demister, ensuring that there is at least one section of packing below to improve absorption efficiency. The top of the tower is equipped with a wire mesh demister to prevent gas from carrying liquid droplets and ensure the quality of emissions.

Process principle：

The absorption tower utilizes the characteristics of NMP and water being miscible in any ratio and highly water-soluble to treat VOCs tail gas, which can control the VOCs emissions in the tail gas within 15-30mg/m3.
