Tower free distillation equipment is a new type of high-efficiency distillation equipment. This device applies supergravity technology to continuous distillation processes in industrial production. The tower free distillation equipment consists of one or more high-speed rotating rotors, and gas-liquid flows through the rotors in a reverse flow manner for contact mass transfer. A commonly used distillation tower with a height of 1.2 meters is equivalent to a height of 15 meters, which is a major breakthrough over traditional plate towers and packed towers. It has been identified by a national expert group and the product has reached a leading level (invention numbers: ZL011343214, ZL200510049145.1, US 7344126 B2). In 2007, it was approved by the National Science and Technology Innovation Fund. In 2008, it won the first prize for scientific and technological progress from the China Petroleum and Chemical Industry Association. In 2010, it won the second prize for scientific and technological inventions from the Ministry of Education. The tower free distillation equipment is widely used for the recovery and product separation and purification of organic solvents such as ethanol, methanol, acetone, and ethyl acetate. It has been industrialized and applied in more than 600 sets in industries such as raw materials, pharmaceutical intermediates, fine chemicals, biodiesel, environmental protection, and liquor production.

Below, the editor will briefly introduce the advantages and characteristics of tower free distillation equipment, as follows:

⑴ Simple operation and easy maintenance;

⑵ Low investment and management costs;

Good performance, high efficiency, and low energy consumption;

⑷ Short processing time, small liquid holding capacity, and strong anti blocking ability;

⑸ Low height, small size, safe and reliable.
