Abstract

The invention relates to the technical field of chemical processing of organic polymer compounds, in particular to a n-butane and isobutane separation tower in the isomerization of n-butane, comprising a separation tower shell whose lower end is fixedly connected with a separation tower seat, and the separation tower shell The lower end of the body is fixedly connected with an intake pipe group, and the inner top of the separation tower shell is connected with a separation mechanism, the separation mechanism includes a main separation box and a pair of auxiliary separation boxes, between the main separation box and the auxiliary separation box A continuously replaceable separation belt is provided, and a wind drive unit is connected to the inside of the air intake pipe group, and a transmission assembly is connected between the wind drive unit and the continuously replaceable separation belt. Cooperating with the continuous replacement separation belt, it can maintain the continuous and stable separation effect of the continuous replacement separation belt, without stopping to feed the mixture of n-butane and isobutane, and improve the separation efficiency.

Description

technical field [0001] The invention relates to the technical field of chemical processing of organic macromolecular compounds, in particular to a separation tower for n-butane and isobutane in n-butane isomerism. Background technique [0002] Isomerization of n-butane is a very important reaction in the petrochemical industry. Its product isobutane is one of the raw materials for the production of high-octane gasoline. The dehydrogenation product of iso-butane can be used to produce unleaded gasoline additive methyl Tertiary J ether and ethyl tertiary butyl ether. The isomerization reaction mechanism of n-J alkane is related to the type of catalyst. At present, the traditional rectification method is mainly used for separation. However, due to the close boiling points of n-butane and isobutane, The process of separating n-butane and isobutane by means of rectification is very energy-intensive. Therefore, it is necessary to study an environmentally friendly new technology t...
