The methanol comprehensive utilization project is a comprehensive project that uses methanol as the core raw material. Through a series of advanced technologies and processes, it achieves the high - value - added conversion of methanol and produces a variety of chemical products. This project makes full use of the rich chemical properties of methanol, aiming to extend the methanol industry chain, improve resource utilization efficiency, and create significant economic and social benefits.
Project Background：As a basic organic chemical raw material, methanol has a wide range of sources and can be prepared from various raw materials such as coal, natural gas, and biomass. With the adjustment of the global energy structure and the development of the chemical industry, the production capacity of methanol is constantly increasing. Therefore, the comprehensive utilization of methanol and the development of its downstream high - value - added products have become an important direction for the development of the industry.
Main Products and Processes
Olefin Products：The methanol - to - olefins (MTO/MTP) technology is adopted to convert methanol into important olefin products such as ethylene and propylene. These olefins are the basic raw materials for synthesizing numerous chemical products such as plastics, rubbers, and fibers. In the MTO process, methanol is converted into ethylene and propylene through a complex reaction process under the action of a specific catalyst. The reaction conditions are mild, and the product yield is high.
Formaldehyde and Downstream Products：Formaldehyde is produced by the oxidation of methanol, and formaldehyde can be further processed to produce urea - formaldehyde resin, phenolic resin, etc. Urea - formaldehyde resin is widely used in the wood processing industry as an adhesive, while phenolic resin has characteristics such as high - temperature resistance and high strength and is used to manufacture insulating materials, friction materials, etc.
Acetic Acid：Acetic acid is produced by the reaction of methanol with carbon monoxide. Acetic acid is an important organic chemical raw material and is widely used in the food, pharmaceutical, chemical and other fields. This process uses advanced carbonylation technology, with high reaction selectivity and good product quality.
Project Advantages
Significant Economic Benefits：By producing a variety of high - value - added chemical products, the utilization value of methanol is increased, bringing considerable profits to enterprises. At the same time, the implementation of the project can also drive the development of upstream and downstream related industries, creating more economic growth points.
Comprehensive Resource Utilization：It realizes the in - depth development and comprehensive utilization of methanol resources, improves resource utilization efficiency, and reduces resource waste.
Advanced and Reliable Technology：The adopted process technologies have been verified by industrial practice and are characterized by maturity, stability, and high efficiency, ensuring the long - term stable operation of the project.
Environmental Impact and Countermeasures：During the production process, the project will generate certain waste gas, waste water, and waste residue. To reduce the impact on the environment, the project is equipped with advanced environmental protection facilities. The waste gas is treated by desulfurization, denitration, dust removal, etc. and discharged up to the standard. The waste water goes through processes such as biochemical treatment and advanced purification to achieve up - to - standard discharge or recycling. The waste residue is classified and treated, with some being recyclable and the non - recyclable being landfilled safely.
