Technical Abstract: White hide deliming requires the removal of un-bound lime as well as bound lime. This can be accomplished sequentially by washing the hides in pure water followed by an appropriate deliming solution. The objective of this paper is to determine the optimal wash parameters for each using a mathematical physical process model. The sorption isotherms and effective diffusion coefficients for bound and unbound lime was determined experimentally and will be presented. The information obtained from these experiments was inserted into the process model to determine the most economical process parameters for deliming.
