Drying method for isododecane production

Abstract

The invention provides a drying method for isododecane production, which is matched with a drying tower convenient to climb for use, a base and a drying tower body are included, the preparation method comprises the following steps: 1) prepared crude isododecane is conveyed into a gas-liquid separator for water separation, and large-component water is removed; 2) conveying the crude isododecane output from the gas-liquid separator into a drying tower convenient to climb for drying so as to finish the drying work, and then conveying the isododecane into an odor removal tower for odor removal; wherein the drying tower convenient to climb in the step 2) comprises a base and a drying tower body; the drying work of isododecane can be completed, meanwhile, the provided drying tower body 2 convenient to climb can be convenient for people to climb to the top of the drying tower body 2 for overhauling work, so that the overhauling efficiency is greatly improved, meanwhile, the safety coefficient of workers during climbing is improved, and the drying tower is convenient for people to use.

Description

technical field [0001] The invention relates to the technical field of iso-dodecane production equipment, in particular to a drying method for iso-dodecane production. Background technique [0002] Isododecane is a highly branched saturated dodecane, which does not have the oily smell of low-carbon alkanes, and has a relatively fast volatilization speed. It can be used as a substitute for volatile silicone oil for The skin feels very refreshing in cosmetics, and can be widely used in various cosmetics, skin care / hair care products, aerosols and other fields. Isododecane usually comes from the hydrogenation of isobutylene trimer (TIB), which is produced after hydrogenation To form crude isomerized dodecane, steps such as dehydration, drying and deodorization are required to support isomerized dodecane; [0003] In the production of isododecane, there is a process of drying the crude isododecane produced. The existing method is to use a drying tower for drying, and the drying...

Problems solved by technology

[0003] In the production of isododecane, there is a process of drying the crude isododecane produced. The existing method is to use a drying tower for drying, and the drying tower is divided into different sizes according to the output of the enterprise. Large-scale enterprises Large outdoor drying towers are used, while some small enterprises use small indoor drying towers, and such indoor small drying towers usually have a climbing ladder fixed on their side to facilitate people to climb to the top of the tower. Carry out maintenance work, but the existing small drying towers are usually vertically fixed climbing ladders, which is inconvenient for people to climb. It consumes more energy when climbing, and is prone to the danger of falling, which is not convenient for people to use
