Toyo Engineering, one of Japan’s leading engineering companies, developed an energy-saving distillation tower for a petroleum refinery plant. The new distillation tower can reduce energy consumption like electricity and steam by up to 75% as compared with the existing distillation tower. Toyo developed the SUPERHIDIC distillation tower in alliance with the National Institute of Advanced Industrial Science and Technology (AIST). The research team adopted a design that realizes internal heat exchange with small amount of electricity without using special equipment.
A distillation tower is used to separate substances with different boiling points in a composite through the repetition of evaporation and coagulation, and it consumes lots of energy like electricity and steam. For example, the distillation process consumes about 40% of all energy required in the chemical manufacturing industry. It is critical to decrease the energy consumption of a distillation tower. Toyo plans to get orders for demonstration in 2013 to commercialize the net technology as soon as possible.
Trademark registration of SUPERHIDIC is under way.
