The offer refers to changing of enzyme adding scheme. In comparison with the scheme being operated by the enterprise, according to which enzymes are partially added into the mash mixer and directly added into HDFT unit of the 1st stage, the WHOLE amount of enzymes is suggested to be added into the water for mash preparation before treatment by the homogenizer/dismembrator.
Besides, the complex enzyme “Viskostar” is suggested to be used, which is, based on operating experience of ethanol enterprises in Ukraine, enables to dissolve mash and to work with wash of higher strength (10 … 12abv%).
Beyond that, the suggested scheme of enzyme dosing allows REFUSING from mash acidification by sulfuric acid and reducing operation cost of biomass desulfurization unit after anaerobic fermentation. Measures’ implementation DOES NOT require additional capital and operating investments.
The main point and method of measure implementation has been thoroughly explained while performing the 1st stage of the audit and need no additional explanations or comments.
