At present, Covestro's existing 500,000-ton MDI plant is currently operating normally. In order to meet the increasing MDI market requirements, and to give play to the technological advantages of the enterprise, and to increase the production efficiency of existing plants, Covestro plans to carry out 'MDI 500,000 tons/year. Expansion of production to 600,000 tons/year (tentative)'. Before and after the completion of the project, the production process of MDI equipment is the same as the existing equipment.
Project Production Scale (10,000 tons/year)
According to statistics, the total investment of the project is 10 million euros (80 million yuan), which will be constructed in two phases. The date of first phase production is expected to be 4 quarters of 2018, and the date of the second phase of production is expected to be 1 quarter of 2021.
The increase in production capacity for the first phase of the project was achieved by extending the operation time from 8000h/a to 8760h/a. The production capacity of MDI was increased from 500,000 tons/year to 550,000 tons/year. The scope of production increase includes the MDI device sequence. The nitrobenzene unit, aniline unit, MDA unit, MDI unit and MMDI unit. On the basis of the Phase I expansion of the second phase of the project, the bottleneck transformation of the existing plant will be carried out to increase the production capacity per unit time. , MDI production capacity increased from 550,000 tons / year to 600,000 tons / year. The scope of production increase for the MDA devices, MDI devices and MMDI devices, does not include nitrobenzene devices, aniline devices, the required part of the aniline solution from the outsourcing solution.
