Helical fractionating column

Abstract

The helical fractionating column according to the invention falls into the field of oil separation apparatus for the petroleum refining industry, which comprises a column body (8), and is characterized in that the inside of the column body (8) is divided into three sections, the lower section being jet tray section, the middle section being packing section, and the upper section being floating valve section. And the helical fractionating column has many advantages, such as the integrity of separation, decoloration and deodorization, simple structure, convenient manufacturing and maintenance, and low investment cost as well as high product quality etc., thereby being worthy to be extended in the petroleum refining industry which uses waste plastics and rubbers as raw materials.
