Regarding the production capacity of the methanol-to-olefins project

According to recent reports, the planned production capacity for methanol-to-olefins in China is said to exceed 20 million tons per year; the output from facilities that came online or are scheduled to come online in August alone amounts to around 4.4 million tons per year. (Information from the Shandong Provincial Department of Commerce) So the current questions are: 1. Is there enough raw material? What is the current surplus amount and surplus production capacity of methanol in the domestic market? Could abnormal price changes in methanol, resulting from the expansion of downstream capacity, affect the entire industry? 2. Another situation in China is as follows: delayed coking is used to produce coke from oil, while coal and water are used to manufacture methanol; methanol is then used to produce olefins, propylene, gasoline, etc., with a large amount of water being generated as a byproduct (how should this excess water be utilized?) ), is there a problem with the direction of development? 3. Is there speculation behind the rapid expansion of production capacity? Just like real estate, mung beans, and garlic. Welcome to participate and share your insights. . Note $ # , $ $
There should be three plants for coal-based olefins: two related to Shenhua and Datang Dulong. Judging from the operation in Baotou, things are going quite well there, with some of the units already operating at high capacity!
The use of delayed coking technology in the petrochemical industry is also a last resort, aimed at improving resource utilization and increasing project profits. This cannot be compared to coal-to-oil and coal-to-chemicals technologies; therefore, there is no issue regarding direction
Currently, the operating rate of methanol plants in our country is around 40%. However, due to the unregulated construction of methanol plants in previous years, both large and small enterprises built methanol production lines, resulting in relatively low capacity per plant – with some plants having an annual production capacity of 100,000 tons, 200,000 tons, or 300,000 tons per year. A methanol-to-olefins plant with an annual capacity of 1 million tons requires a corresponding methanol production facility with an annual capacity of around 3 million tons. Given the low production capacity of existing methanol plants and their scattered location, it is not possible to acquire the methanol produced by these plants for use in olefin production. Moreover, the methanol-to-olefins plants that are under construction or planned for construction all come with corresponding methanol production facilities, thereby continuing to increase the total methanol production capacity; this does not address the issue of an excess supply of methanol plants at present. Instead, it is contributing to the surplus of methanol. The ultimate result is the gradual phasing out of existing methanol plants.
With continuous technological advancements, methanol will gradually decrease in the long run. Direct production of dimethyl ether, higher alcohols, and olefins from syngas. It’s still in the research phase at the moment. Currently, in the production of olefins from methanol, companies prefer to produce methanol themselves, which does not alleviate the pressure caused by an excess of methanol. It seems that all methanol plants will need to be expanded and equipped with olefin production units. This is also a rational use of low-carbon resources, and it is beneficial to both the country and its people.
