Inhibition of Gas Hydrate Formation by Lowdosage,Environmentally Benign Inhibitors

摘要

Ice-structuring proteins (ISPs) have been considered as an environmentally-friendly alternative to commercial kinetic inhibitors of hydrate formation. ISPs obtained from certain species of pout (a cold-water fish) have been tested in the literature and in our laboratories and the results are promising. However, insect-based ISPs have been shown to be much more active than fish-based ISPs for freezing point depression. We have done initial testing with insect and fish ISPs in our labs for activity in hydrate inhibition and results are promising.
