Abstract
A gas-enriched liquid delivered at a site of interest that is substantially bubble free after delivery into a lower pressure liquid or gas environment. The delivered gas-enriched liquid is produced by a process comprising the steps of:a) preparing a mixture of gas and liquid;b) compressing the mixture to a pressure such that the gas completely dissolves in the liquid to form a gas-enriched liquid;c) enclosing the gas-enriched liquid within a confined space while retaining substantially the same pressure. The confined space has at least one dimension less than about 0.2 mm, and has at least one opening to a liquid or gas environment site of interest having a lower pressure than that of the pressure of the confined space; andd) delivering the gas-enriched liquid from the confined space out through the at least one exit opening to the lower pressure environment without formation of bubbles.
