Development of a Method for Producing Molded Hydrates of Natural Gas

Abstract

Abstract The article proposes a method for producing natural gas hydrates in the form of cylindrical pellets with a continuous production cycle. The method involves the formation of hydrates in a natural gas atmosphere at pressures from 5 to 8 MPa and a constant temperature equal to + 5 °C, in the form of a hydrate slurry formed by stirring a hydrate-forming liquid in an environment of a hydrate-forming gas. The resulting gas hydrate slurry is collected in a perforated sleeve equipped with a filter and pressed into cylindrical pellets using a hydraulic plunger. The main feature of the developed method is to simplify the technology for obtaining the finished product in the form of cylindrical pellets of natural gas hydrates by placing all production processes within a single sealed tank.
