... And so does this single column for multi-component mixtures

Article Abstract:

Sumitomo Heavy Industries Co. of Tokyo, Japan, is now marketing a new continuous distillation process that isolates each of three-component mixtures in a single tower. The process, which was co-developed with Kyowa Yuka Co. of Tokyo, Japan, has been tested to be with commercial value in Kyowa Yuka's 30,000-mt/yr ethyl acetate plant. Sumitomo claims the new process generates energy cost reduction by about 30% and construction costs and installation space also by about 30%. The distillation process is also claimed to have produced a 99.999% form of ethyl acetate during the testing.

Destroy mixed contaminants in one step instead of three

Article Abstract:

Osaka Gas Co. of Osaka, Japan, has cultivated a new catalytic wet oxidation (CWO) process designed to decompose organic and cyano compounds in industrial wastewater. Both organic and cyano composed are decomposed into CO2, H2O and N2, using a platinum catalyst added in a mixture of zirconia and titania. The one-step CWO process, which does not produce NOx byproducts since the process uses high temperatures, could reduce treatment cost by about 30% as compared to the existing three-step conventional treatments.
