Application of Column/Tower equipment in the chemical industry

In the refining, chemical and light industrial production, gas and liquid two-phase direct contact for mass and heat transfer process is a lot of, such as distillation, absorption, desorption, extraction, etc.. These processes are in a certain pressure, temperature, flow and other process conditions, in a certain equipment to complete. Because of the process of the two media is mainly the quality of the exchange, so the realization of these processes is called mass transfer equipment; from the appearance of these devices are installed vertically in the barrel described as a device, shaped like a "tower", it is customary to refer to it as a tower equipment.

Column / Tower equipment for gas, liquid or liquid, liquid and liquid phase to provide suitable conditions for full contact, that is, adequate contact time, separation space and the area of mass and heat transfer, so as to play the inter-phase exchange of quality and heat for the purpose of realising the process required by the production process, the production of qualified products. Therefore, the performance of the tower equipment on the whole unit of product yield, quality, production capacity and consumption quota, as well as three waste disposal and environmental protection have a significant impact.

Column / Tower equipment is an important production equipment widely used in chemical, petroleum and other industries. It can make gas-liquid or liquid-liquid two-phase close contact between the two phases, to achieve the purpose of interphase mass transfer and heat transfer. In addition, the cooling and recovery of industrial gases, gas wet netting and drying, as well as both gas-liquid two-phase mass transfer and heat transfer of humidification, dehumidification and so on. Chemical production in the handling of raw materials, intermediate products, crude products are almost always composed of a number of components of the mixture, and most of them are homogeneous substances. In order to meet the needs of storage, transport, processing and use in production, it is often necessary to separate these mixtures into purer or almost pure substances. The basic function of the Column / Tower equipment is to provide gas, liquid and two-phase to full contact opportunities, so that heat transfer, mass transfer two transfer process can be carried out quickly and effectively; but also to make contact after the gas, liquid and two-phase separation in a timely manner, each other do not entrain.
