Basf Develops New Technology To Reduce Ghg Emissions

BASF’s team of experts have been actively working on developing novel technologies to significantly lower emission of greenhouse gases during production processes. The company’s Carbon Management Program collects all this work in one place. Production processes of the essential chemicals contribute to nearly 70 percent of the total greenhouse gases emissions released by the chemical industry. One of the company’s project teams has developed a process to manufacture methanol that does not release any greenhouse gas emissions.

The team has currently filed for a patent for the revolutionary technology. If the technology is integrated at the industrial level, the complete production process, right from syngas production to pure methanol, will not emit any carbon dioxide. Methanol is ordinarily made from syngas, which is primarily obtained from natural gas along with a blend of steam and autothermal reforming. Special catalysts are used to convert it into crude methanol, which can be further processed after purification. In the new process, the syngas forms upon partial oxidation of natural gas, that does not result in any carbon dioxide emissions and has proven to be beneficial in a study that was jointly conducted with Linde Engineering. The following process steps of methanol synthesis and distillation can be executed without any changes. There was a need to resolve the merging and processing of the waste gas streams issue that usually arises during methanol synthesis and distillation that cannot be evaded even with optimal process management. The waste gas streams, including methane, carbon dioxide, carbon monoxide, and hydrogen is burnt in an Oxyfuel process using pure oxygen.

This ends up in a small quantity of fuel gas with a high concentration of carbon dioxide. To ascertain that the carbon enclosed in the dioxide is not lost and can be reused in the methanol synthesis, the captured carbon dioxide is fed again at the beginning of the process, although this step requires additional hydrogen. Dr. Maximilian Vicari, Project Manager, BASF’s Intermediates division believes that it will take nearly a decade for the process to be incorporated in an industrial plant.
