METHOD FOR BIOSTABILISATION OF PETROLEUM PRODUCTS

摘要

The invention relates to petroleum chemistry and petroleum processing and concerns the protection of petroleum products against micro-organisms. The essence of the invention consists in the following: the base of hydrophobic polyalkylenguanidine or a mixture thereof with the base 1.6 diguanidingexane in equal parts, or the base 1.6 of diguanidingexane mixed with the base of low-molecular polygexametyleguanide in equal parts, or the mixtures of corresponding chlorides in equal parts dissolved in a suitable organic solution is added to a petroleum product possibly containing subtrade water. The mixtures are introduced in amounts of 10-50 g/t. In case of the presence of subtrade water in the petroleum product, hydrophilous water-soluble salt of diguanidingexane or polyoxyalcylenguanide or their mixtures with catamine AB in equal parts in amounts of 100-500 g/t are introduced into said water. Either chloride or phosphate of polyalkylenguanidine, or chloride or phosphate of polyoxyalcylenguanide are used as salt. The inventive method makes it possible to reduce the contamination of the petroleum products by micro-organisms.
