PROCESS FOR MAKING UNDERGROUND STORAGE CAVERNS

摘要

This invention relates to a new method for making large underground storage caverns inbedded or domal salt deposits for the storage of fluid materials in areas where solution miningwater temperatures are low by a process which significantly reduces the amount of time required tomake equivalent sized underground storage caverns and which is economically feasible andfriendly to the environment. The process includes the warm water solution mining of theunderground salt deposits in a manner which conserves the heat contained in the supernatant brinefrom the underground cavity and employs this heat as a significant source for warming the wateremployed in the solution mining operation.
