ENVIRONMENTAL THERMODYNAMIC HYDRATE FORMATION INHIBITORS

摘要

PURPOSE: An environmental thermodynamic hydrate formation inhibitor is provided to thermodynamically suppress formation of a gas hydrate due to a reaction between gas and moisture and to be harmless to a human body and environment. CONSTITUTION: A hydrate formation inhibitor is an amino acid or a derivative thereof. The amino acid or the derivative thereof is one or more selected from L-proline, L-serine, glycine, L-alanine, and L-valine. A method for inhibiting formation of a hydrate comprises a step of injecting the amino acid or the derivative thereof into a moisture-containing gas up to a maximum solubility.
