Large-scale Methanol Synthesis Technology
Never stop on the development path of pursuing green chemical industry
Innovation
We adopt the self-developed high-efficiency water-cooled reactor, water-cooled plate reactor, and air-cooled reactor, to achieve the coupling of process flow, reaction mechanism, and heat recovery, with high methanol purity, large by-product steam volume, and high steam quality.
Technical Advantages
GC-type Water-cooled Reactor:
01
Reactor with Low Resistance: 0.15~0.25MPa
02
High Ammonia Purity: 17.5~18.5%
03
Efficient Heat Recovery and High-quality By-product Steam: 950~1150kg/TNH3

GC-type Gas-cooled Reactor
GC-type Water-cooled Reactor:
01
The gas-cooled reactor has both reaction and heat exchange functions, saving on equipment investment;
02
We adopt spiral structures in the gas-cooled reactor.Uniform gas distribution, safe and reliable equipment structure, better heat exchange design.
03
Reaction temperature distributes in gradient for better methanol synthesis reaction performances; GC-type gas-cooled reactor is connected in series with water-cooled reactors, increasing methanol purity by 4~6%.
Methanol Synthesis Technology

Applications
June 2017
The first domestically produced 1.2 million tons/year large-scale methanol synthesis plant using the water-cooled series gas-cooled process and GC-type water-cooled reactor, gas-cooled reactor technology was successfully put into operation, marking the first instance of domestic production of million-ton-level large-scale methanol technology.
