Problems solved by technology

[0005] The application of energy-saving technology for the separation of isoamyl alcohol isomers 2-methyl butanol and 3-methyl butanol is less. The patent CN102010292 preheats the raw material feed with the thermal energy of the steam at the top of the tower to achieve better separation effect, but did not elaborate on its energy-saving benefits

Embodiment Construction

[0022] Describe the present invention in further detail below in conjunction with embodiment:

[0023] Referring to the drawings, the present invention includes a rectification tower 1 , a heat pump 2 , a drive heat exchanger 5 , a reboiler 4 , a surge tank 10 and a reflux pump 6 . The rectification tower 1 seals the top of the tower with the inlet of the heat pump 2 through pipelines. The heat pump 2 is provided with a driving device 3. The outlet steam of the heat pump is sealed and connected to the shell side of the reboiler 4 through pipelines. The inlet of the tube side of the reboiler 4 passes through pipelines. It is connected with the tower bottom of the rectification tower, and the tube side outlet is connected with the vapor phase inlet of rectification tower 1. The shell-side outlet of the reboiler is airtightly connected to the buffer tank 10, and the buffer tank 10 is airtightly connected to the inlet of the reflux pump 6. The outlet of the reflux pump is divided ...

Abstract

The invention relates to a process and a device for distilling and separating isoamylol isomeride by a heat pump. The device comprises a distilling tower, the heat pump, a reboiler, a buffer tank, a driving heat exchanger and a reflux pump. The distilling tower is provided with a tower top vapor phase port and a tower top discharge outlet, the tower top vapor phase port is hermetically connected with an inlet of the heat pump through a pipeline, the reboiler is provided with a shell pass inlet, a shell pass outlet, a pipe pass inlet and a pipe pass outlet, the shell pass inlet is hermetically connected with the heat pump through a pipeline, the pipe pass inlet of the reboiler is hermetically connected with a tower bottom of the distilling tower, the pipe pass outlet is connected with a vapor phase port on the lower portion of the distilling tower through a pipeline, and the shell pass outlet is connected with the buffer tank. The bottom of the buffer tank is provided with a liquid phase discharge outlet which is connected with an inlet of the reflux pump. An outlet of the reflux pump is divided into two material flows, one is connected with a tower top reflux port of the distilling tower through a pipeline, and the other one is used as discharge on the tower top.

Description

technical field [0001] The invention belongs to the technical field of chemical separation and energy-saving transformation, and in particular relates to a process and a device for separating isoamyl alcohol isomers by heat pump rectification. Background technique [0002] Fusel oil is a by-product of the production of alcohol by fermentation. my country's fermented alcohol production is about 6 million tons, of which fusel oil accounts for 0.3%. Isoamyl alcohol, also known as 3-methyl butanol, and its isomer 2-methyl butanol (commonly known as optical isoamyl alcohol) are the main components of fusel oil. [0003] At present, the mixture of two isomers is mostly used in China, and its mass fraction is about 15% of 2-methyl butanol and 85% of 3-methyl butanol. It is used as the starting material of spices and further reacted Form aldehydes, acetals, acids and esters and other products. Its mixture is relatively easy to produce, but its added value is relatively low. 2-Me...
