Starch Remover - HT Starch Enzyme
Description
HT Starch Enzyme is a high temperature resistant alpha-amylase, produced by the submerged culture of Bacillus licheniformis under state of the art process. it randomly hydrolyses the alpha-1,4 glucosidic bonds of starch, glycogen and their hydrolysates, to yield soluble dextrin and oligosaccharide, thus to bring a rapid decrease to the viscosity of the gelatinous starch solution. Over-hydrolysis of starch yields a small amount of glucose and maltose.

Application & Features
HT Starch Enzyme is used in filter-cake removal operations. It attack only starch and polymers, break polymer gels clean up filter-cake components. Because starch fractions in drilling formations are much larger than those of the polymers, just removing starch from filter cake significantly reduces flow-initiation pressure and permeability impairment.
HT Starch Enzyme exhibits excellent heat-resistance. It is easily soluble in water and environment friendly.
HT Starch Enzyme is available with enzyme activity* of 20,000 U/ml, 30,000 U/ml and 60,000 U/ml according to customer's requirements on efficiency and application.
