Abstract: The urgency of the discussed issue: Pulping from fast-growing non-woody raw material for its further conversion into bioethanol is one of the priority areas in the chemical engineering. Development of this area implies designing of new process equipment models both for implementing unit operations and for the entire process as a whole. Along with that, adaptation of such equipment is inseparable from establishing optimum conditions for the process, whereby the maximum efficiency of equipment use is achieved. The main aim of the study: Establishment of optimum conditions for the unit operations of delignification and washing-off of the pulp that is obtained from oat hulls. The methods used in the study: The methods are based on experimental-statistical processing of experimental results of the unit operations. The results: The problem of determining the optimum conditions for each of the unit operations was solved based on processing of the results of the experimental data describing the kinetics of the unit operations (feedstock delignification, pulp washing-off, and enzymatic hydrolysis of pulp substrates). If the optimum conditions are met, the unit operations provide the maximum yield of the finished product with the relevant quality.
