Development and Prospect of Distillation Technology in Petroleum Refining Industry

Focused on the energy conservation and reinforcement of distillation process, a comprehensive analysis about the technology developments of tower internals was presented, including tower tray, structure packing and supporting. Meanwhile, the application and development of distillation technology in the field of petroleum refining industry were concluded here. Also, to be a new concept, the application of silicon carbide foam in manufacturing tower tray and packing made distillation process more efficient. Through coupling the low temperature cogeneration technology with the distillation process, it was possible to recycle the thermal energy with low temperature, which was wasted in the distillation process before, and to make the use of energy in the distillation process more scientific and exhaustive, as companied with thermal coupling distillation technology, heat pump distillation technology, multi effect distillation technology and other energy saving technology. Benefiting from the mass-transfer element made by new material and low temperature cogeneration technology, the development of green distillation process will be more rapid and easier.
