Present issue proposes a solution to the problem of the waste oils with different composition recycling into esters of fatty acids and low-molecular alcohols by using flexible type technology. Waste oils differ in the composition of hydrocarbon radicals of the vegetable oils triglycerides and in the content of the free fatty acids impurities. For waste oils processing it is advisable to use technology options that differ in combinations of basic technological operations. An algorithm is proposed for selecting the main technological operations and their combinations for inclusion in the technology process, taking into account the composition of the recycling raw materials and the type of product obtained. The flexibility of the technology is provided by using different combinations of reactor blocks, each of which is designed to perform one of the provided technological operations. The developed flexible type technology was tested in the recycling of experimental batch of the low-eruption rapeseed oil waste.

ABSTRACT In addition to the previously described permeability disturbance in the blood aqueous barrier of the eye, measured as an increase of the aqueous flare, a series of transitory systemic effects have been recorded following the subcutaneous injection of synthetic α-MSH: marked increase of the free fatty acids in plasma, decrease in the serum calcium level, decrease in the blood pressure, increase in the skin temperature, increased frequency and diminished amplitude of respiration, presence of slow waves in the EEG. There is a correlation between the magnitude of the aqueous flare increase and the increase of free fatty acids in plasma and also between the aqueous flare and the minimum serum calcium level.
