Co-production system for methanol and deeply processed ethanol gasoline and use method of co-production system

Abstract

The invention discloses a co-production system for methanol and deeply processed ethanol gasoline. The system comprises a gasification furnace, a washing tower, a conversion furnace, a first purification tower, a first compressing device, a methanol synthesis tower, an acetic acid synthesis device and an ethanol synthesis device which are connected in series sequentially, wherein the washing tower is further connected with a second purification tower, a low-temperature cooling box and a second compressing device in series sequentially, and the second compressing device is connected with the acetic acid synthesis device; and the conversion tower is further connected with a third purification device and a PSA (pressure swing adsorption) hydrogen production device in series sequentially, an outlet of the PSA hydrogen production device is connected with the ethanol synthesis device, and a tail gas outlet of the PSA hydrogen production device and a tail gas outlet of the low-temperature cooling box are connected with the conversion furnace respectively. The invention further provides a method for performing co-production by adopting the system. The method is simple, convenient, low in cost and capable of producing methanol and fuel ethanol, and the product structure can be completely adjusted according to market requirements.

Description

technical field [0001] The invention relates to the field of chemical product production equipment, in particular to a system for methanol and deep-processed ethanol gasoline and a method for using the same. Background technique [0002] With the reform of my country's energy policy and the rapid economic development for more than 30 years, a large amount of funds have poured into the construction of energy development field (especially coal resources). my country's existing energy structure is a basic pattern of lack of oil, little gas, and rich coal. At present, the production of chemical fertilizers and chemicals basically uses coal as raw material, resulting in large investment and high energy consumption in the chemical fertilizer industry. Moreover, the product is often single, and once the main product is blocked, it cannot be adjusted. At the same time, most of my country's coal production areas are distributed in western regions such as Inner Mongolia, Shaanxi, an...

Problems solved by technology

At present, the production of chemical fertilizers and chemicals basically uses coal as raw material, resulting in large investment and high energy consumption in the chemical fertilizer industry

And often the product is single, once the main product is blocked, it cannot be adjusted

At the same time, most of my country's coal production areas are distributed in western regions such as Inner Mongolia, Shaanxi, and Xinjiang, and the developed agricultural production areas are far away from energy bases, resulting in high transportation costs

These have brought fatal adverse effects to fertilizer and chemical enterprises
