METHOD OF STORING LIQUEFIED GASES AT LOW TEMPERATURE IN A SUBTERRANEAN CAVITY

摘要

IN THE PATENT OFFICE PATENT APPLICATION entitled "METHOD OF STORING LIQUEFIED GASES AT LOW TEMPERATURE IN A SUBTERRANEAN CAVITY" in the name of Alain BOULANGER During the process of cooling, the stresses in the earth pass first through a maximum compression and then this gives place to traction up to the moment when fissures appear. The application of cooling is conducted so as to reduce the size of these fissures and to prevent their propagation through the compressed zone. They are plugged preferably by spraying water in the course of application of cooling. CA-USA
