Integrated Gasification Combined Cycle by Pressurized Two-Stage Gasification Technology using Waste Plastics as Feedstock

Abstract

The discharge of waste plastics reached to 9,760,000 tons in 1999. Among these, the ratio of 46% was used effectively, and 54% was simple incineration and reclamation disposal. A large amount of simple incineration and reclamation disposal is not only the problem from a viewpoint of environmental preservation that, but the effective use is called for construction of recycle system society. In this study, useful synthetic gas is manufactured by the Pressurized Two-Stage Gasification technology using waste plastics, which is developed and the commercialized in recent years, and is utilized as a fuel of gas turbine for the efficient combined cycle power generation system.
