Coarse metaclazepam dealcoholization transformation system

Abstract

The invention discloses a coarse metaclazepam dealcoholization transformation system. The system comprises a kettle body, a heat recovery heat exchange device, a methanol condenser, a hot oil coolingpipe, a cold oil heating pipe, a methanol input pipe, a methanol output pipe and a dealcoholization backflow pipe, wherein one end of the hot oil cooling pipe is connected to the bottom of the kettlebody, the other end of the hot oil cooling pipe is communicated to an oil recovery device, one end of the cold oil heating pipe is connected to the upper part of the kettle body, the other end of coldoil heating pipe is communicated to an oil supply device, parts of the hot oil cooling pipe and the cold oil heating pipe are positioned inside the heat recovery heat exchange device, one end of themethanol input pipe is connected to the methanol condenser, the other end of the methanol input pipe is connected with a vacuum pipe, one end of the methanol output pipe is connected to the methanol condenser, the other end of the methanol output pipe is connected to the top of the kettle body, one end of the dealcoholization backflow pipe is connected to the upper part of the kettle body, the other end of the dealcoholization backflow pipe is connected to the hot oil cooling pipe, a cooling cavity is arranged inside the methanol condenser and is connected with a cooling water output pipe anda cooling water inlet pipe. The system has the beneficial effects of improvement of production performance, energy saving and environmental protection.

Description

technical field [0001] The invention relates to a transformation system, especially a reformation system for dealcoholization of crude methyl esters. Background technique [0002] Biodiesel is a fatty acid monoalkyl ester obtained by transesterification of animal and vegetable oils and alcohols (such as methanol or ethanol), the most typical is fatty acid methyl ester, biodiesel is an excellent supplement and substitute for petrochemical diesel, biodiesel During the refining process of diesel oil, there are many impurities, such as glycerin, methanol, low boiling substances, etc., resulting in low product purity, poor product quality, high raw material consumption, and when the methanol content in the crude methyl ester is low, it is difficult to evaporate. Under limited conditions, it is very difficult to demethanolize crude methyl esters, and the investment is large, the effect is poor, and the process is complicated. [0003] Therefore, higher technical parameter require...
