The evaluation of model of deproteination process

Original language description

Chrome-tanned leather manufacture, so-called shavings are produced which represent a considerable volume of hazardous waste. One of the ways of its processing is the chemical mode (acid, alkaline or enzymatic hydrolysis). For a number of reasons, the method most suitable is the enzymatic, 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 measuredand analyzed date are evaluated within mathematical model.
