Tower equipment is a device used for separating and absorbing gases, which utilizes the density differences between different gases for separation, or absorbs gases with liquids. Tower equipment typically consists of a cylindrical tower body and internal structural components, equipped with intake and outlet ports, liquid inlet and outlet, etc. The internal structural components of tower equipment come in various forms, such as packed beds, sieve plates, and bubble caps, which can be selected according to different process requirements. During operation, gases and liquids enter the tower through different inlets, where they are fully contacted and react within the tower to achieve separation or absorption. Tower equipment is widely used in the oil, chemical, and environmental protection industries for gas and liquid separation, absorption, and purification processes. The design of tower equipment must consider process requirements, fluid properties, flow rates, as well as the form and height of the structural components to ensure the separation efficiency and operational stability of the tower equipment.
