Research & Development of Natural Gas Transportation System with Gas Hydrate (NGH Chain)

Abstract

This paper describes a natural gas transportation system with gas hydrate. This system is called NGH(Natural Gas Hydrate) Chain. It was reported that the capital cost of NGH Chain is 20% lower than LNG Chain^<(1)>. NGH Chain consists of production plant, career and regasification plant. MHI/JNOC have planed 4-step development for NGH production plant : an simulated gas hydrate bench scale test, a methane hydrate bench scale test, a pilot plant test and a commercial plant. This paper reports the simulated gas hydrate bench scale test.
