What is the production cost of MTBE?
Thread Content
The company is currently considering an MTBE project and would like to know what the production cost of MTBE is.
MTBE production cost: The raw materials are isobutylene from liquefied gas (no separation required) and methanol. Common expenses include heating steam, cooling water, electricity for pumps and machinery, equipment depreciation, catalyst depreciation, equipment maintenance costs, and personnel management expenses. In refineries, MTBE is generally used as an auxiliary device with low cost implications.
The costs for labor, water and electricity, and steam generally amount to around 140 yuan per ton of liquefied gas processed (with an isobutylene content of about 20%)
A friend I know has a complete set of such skills; if needed, I can help you get in touch with them
The production process of methyl tert-butyl ether generally includes catalytic etherification, as well as the recovery and purification of the remaining tetrahydrocarbons and methanol. Costs and market prices: The production cost is 3,100 yuan per ton. For a project with an annual production capacity of 100,000 tons of methyl tert-butyl ether in China, the acceleration of the process of making gasoline lead-free creates business opportunities for this substance. The annual sales revenue amounts to 2,110 million yuan, while the average annual cost is 2,000 million yuan.
Under these current circumstances, it’s better to take things slowly for now; the prices of raw materials and products are unstable, and if things don’t work out, losses will be incurred first
The energy consumption per ton of MTBE is generally around 80 kgo/t, which is approximately equivalent to 0.08*3000 = 240 yuan in terms of cost. As for the raw material costs, namely mixed C4 plus methanol, the amount of mixed C4 required per ton depends on the content of isobutylene in that mixed C4； The catalyst consumption per unit depends on your process requirements ； Equipment depreciation ； Labor cost ； Maintenance costs and various fees. Typical corporate accounting uses internal pricing, so it’s meaningless to use that directly.
Regarding the statement upstairs that \"the energy consumption per ton of MTBE is generally around 80 kgo/t, which is approximately equivalent to 0.08*3000=240 yuan\", where does the figure 3000 come from? Is it possible to estimate it in this way? Is the average cost of consuming energy sources such as electricity, steam, and water 3,000 yuan per unit? ?
Now no one can talk about cost issues; wait a while until prices stabilize first. Another approach is to conduct a price correlation analysis between methanol, C4 compounds, and MTBE, in order to dynamically assess the feasibility of such projects over the long term. However, in our country, the volume of MTBE available in the market is very small, so it’s not possible to obtain accurate price data. In fact, what matters most is the purpose for using MTBE. If it’s for blending gasoline, then its use is necessary. For producing high-purity isobutylene, it can also be used as long as the downstream products can be secured. The investment required for an MTBE production facility isn’t high.
It is worth discussing; only isobutylene in the C4 fraction is consumed, and the raffinate can still be sold as C4.
It would be appropriate to do this now. However, the consumption rates are mainly related to the composition of the raw materials, with the azeotropic distillation column being the component that consumes the most resources. You can tell me your material composition and I’ll calculate it for you; or you can simply look up the consumption rates in the book \"Production and Applications of Methyl tert-Butyl Ether\" to carry out the calculations yourself. The investment required for such a processing facility is approximately 10 million yuan per 10,000 tons per year of MTBE produced.
