An energy-saving and environment-friendly isooctane purification and light removal tower

Abstract

The utility model discloses an energy-saving and environment-friendly isooctane purification and light component removal tower. The tower a packed tower body, wherein a box body is arranged in the packed tower body; the box body is located between the two packing layers, the two sides of the box body are fixedly connected with the inner walls of the two sides of the packed tower body through connecting blocks, inclined plates are fixedly installed on the periphery of the top face of the box body, the two gas circulation pipelines located on the same side of the box body are distributed front and back, and the top ends of the gas circulation pipelines penetrate through the inclined plates and are located on the inclined plates. The tower is simple in structure, resource waste is avoided, and the production cost is saved; by rotating the cross-shaped connecting pipe, liquid can be sprayed around, then the liquid can be uniformly sprayed to the packing layers located at the bottom of thepacked tower body, meanwhile, through rotation of the cross-shaped connecting pipe, the liquid and gas can be better mixed, the light component removal effect is further improved, and convenience is brought to production of isooctane.

Description

technical field [0001] The invention belongs to the field of isooctane purification and light removal, in particular to an energy-saving and environment-friendly isooctane purification and light removal tower. Background technique [0002] Isooctane is a clean gasoline additive produced by alkylation technology using mixed carbon four as raw material. It has the advantages of high octane number, low vapor pressure, no sulfur, and no aromatics. In the production process of isooctane, it is necessary to use degassing The light tower performs light removal treatment on isooctane, but when the existing light removal tower performs light removal treatment on isooctane, liquid and gas are continuously added to the light removal tower. Due to the flow of gas and liquid, It is easy to shorten the contact time between the gas and the liquid, resulting in incomplete light removal, and the added liquid cannot be evenly scattered on the packing layer, and at the same time, the contact b...
