dc.description.abstract In this paper, the authors show the usefulness of theoretical tools of chemical engineering in natural polymer processing, namely on the example of white hide deliming. White hide is a consequent product in the processes in which raw hide is transformed into leather. It is produced in the de-hairing stage which follows the soaking operation. For next operation, tanning, it is necessary to remove calcium hydroxide from white hide. Mathematical descriptions of both non-chemical and chemical deliming are presented, concentration fields of the reacting chemicals described and the importance of the acido-basic boundary inside the white hide shown. Experimental determination of the effective diffusion coefficient is also included. The presented mathematical models can serve as a very good basis for rationalization of the deliming process, save considerable amounts of energies, deliming chemicals and technological water, and make the whole process more environmentally friendly. en
