AdiP technology Covestro nominated for German innovation prize

Energy efficiency

GermanyThe AdiP technology of Covestro has been nominated for the German Innovation Prize for Climate and the Environment (IKU). It is awarded by the Federal Ministry of Economic Affairs and Climate Action.

AdiP helps Covestro to significantly reduce the energy consumption and thus CO2 emissions in MDI production. Up to 40% of steam and 25% of electricity can be saved per ton of MDI, cutting energy-related CO2 emissions by up to 35%.

In the fall of 2020 Covestro announced a significant breakthrough in the production of the rigid foam component MDI. Covestro put into operation a pilot plant based on the innovative AdiP technology at its Brunsbüttel site.

Higher output

AdiP stands for adiabatic-isothermal phosgenation, which describes the key feature of the technology. The reaction is controlled more efficiently and does not require an external heat supply, as the heat generated during the reaction process is used.

As a result, this production process significantly reduces energy consumption and CO2 emissions in MDI production. Thanks to AdiP technology up to 40% steam and 25% electricity can be saved per ton of MDI produced in an MDI plant – and CO2 emissions are thus reduced by up to 35%.

Another advantage of the innovative method is that the production output increases by 50% compared to the technology currently in use. As a result, future MDI production plants based on AdiP technology can be smaller than in the past.
