Embodiment 1

[0024] Such as figure 1 As shown, the device is a device that processes 3333 kg of fusel oil per day, and the production process of dehydration and refining of fusel oil fractions is mainly completed on a batch rectification device. The main composition of raw materials is shown in Table 2.

[0025] serial number

[0026] 3333 kilograms of raw materials from fusel oil raw material tank 1 and the water content in ethanol raw material tank 2 are 4700 kilograms of ethanol entrainers that are put into the tower still of batch rectification tower 3 and carry out batch rectification operation, dehydration operation The pressure is normal pressure, and various products are collected and extracted from the top of the tower to industrial ethanol tank 5, isopropanol tank 6, n-propanol tank 7, isobutanol tank 8, isoamyl alcohol tank 9 and ethyl caprate tank 10 Etc., after the transition cut in 4 is collected, mix into next batch of material, reclaim through refining operation...

Embodiment 2

[0030] Such as figure 2 As shown, the device handles 1,000 tons of fusel oil per year. The dehydration of the fusel oil fraction adopts continuous rectification operation, and the fusel oil is purified by rectification after dehydration. The main composition of raw materials is shown in Table 2.

[0031] The 139 kg / h of raw material from fusel oil raw material tank 1 and the 187 kg / h ethanol entrainer with a water content of 0.2% in ethanol raw material tank 2 continuously enter fusel oil fraction continuous dehydration tower 14, and the dehydration operating pressure is normal pressure. The industrial ethanol continuously extracted from the top of the dehydration tower is sent to the industrial ethanol tank 5, and the dehydrated fusel oil extracted from the bottom of the tower is sent to the fusel oil rectification and purification device 15. Fusel oil refining unit can adopt continuous and intermittent operation to obtain various alcohol and ester products, which are sent ...

Abstract

A method for removing water content in fusel oil is used for production of alcohol fuel to solve water content to be too high when it is directly mixed into alcohol fuel. By azeotropic distillation, fuel alcohol is used as entrainer to remove water content in it. Various purified alcohols can be obtained from it by refinement.

Description

technical field [0001] The invention relates to a method for dehydrating fusel oil fractions in the fuel ethanol production process. Background technique [0002] Due to the shortage of global petroleum resources and the rapid development of bio-enzyme technology, the production of fuel ethanol by fermentation to replace gasoline is becoming more and more popular. The annual output of fuel ethanol by fermentation in the United States has reached 10 million tons. my country's work to promote the use of ethanol gasoline for vehicles has been fully launched. In April 2001, two national standards of "denatured fuel ethanol" and "ethanol gasoline for vehicles" were promulgated, and the amount of ethanol added in ethanol gasoline for vehicles was 10%. At present, the use of ethanol gasoline for vehicles has been fully promoted in the three northeastern provinces of my country. [0003] In the process of fuel ethanol production, most of the water i...
