I heard that the production of methanol generates a large amount of waste heat, and I would like to find out more details about this; I have a technology that can make use of this waste heat. It took me over 10 years to develop a set of inorganic chemical engineering technologies that enable efficient utilization of the millions of tons of ferrous sulfate and ferrous chloride produced as by-products in the titanium dioxide and steel industries. The equipment investment can range from 1 million to 100 million; with an investment of 20 million, annual profits can reach 80 million. If there are waste heat power plants and by-product steam, profits can reach 100 million. I would like to consult experts regarding the waste heat resources available for methanol production; please feel free to send guidance via email at myben@126.com
The temperature of the methanol reaction bed is 250–280°C, enabling the production of low-pressure steam
Hello, could the original poster briefly describe your project?
It can’t be explained in just one or two sentences; if you’re interested, send me an email at myben@126.com
The methanol synthesis reaction is a highly exothermic reaction that takes place under the action of copper-based catalysts. The water-cooled synthesis reactor is connected to a steam drum, which generates low-pressure steam; the temperature of the reaction bed is maintained between 220 and 280 degrees.
To produce methanol, it is first necessary to create syngas. Is there waste heat in the process of producing syngas?
There are two units in the process of producing methanol from coke oven gas that can generate by-product steam: the conversion unit and the synthesis unit. Depending on the scale of the project, these two units together are able to produce approximately 20 tons of steam per hour
That’s quite a large amount – 400 tons of steam per day, which amounts to over 100,000 tons per year
The residual heat you mentioned should be the vent gas
