Contribution to purification of chrome cake with hydrolysis into automation equipment

Popis výsledku v původním jazyce

Technological research has need high quality and progressive equipment. The arguments are make all research work quickly, in detail and with minimal cost. We use this way to testing and modeling of deproteination processes. Chrome-tanned leather manufacture, so-calledd shavings are produced which represent a considerable volume of hazardous waste. One of the ways of its processing is the enzymatic hydrolysis, where a soluble collagen hydrolyzate and solid fraction are formed. The utilization of this solid waste of high chrome content requires, in the first place, reducing the content of protein fraction contaminating the material. The chrome cake was deproteinated by alkaline hydrolysis in a pressure vessel, where a 91 % removal of protein from the solid fraction was achieved by conversion into soluble form. All processes are putted to test at laboratory plant. The measured and analyzed date are evaluated within mathematical model.
