Designing of underground coal gasification unit

Abstract

Pakistan is one of the biggest country for coal reserves in the world. Those coal reserves if exploited, will help in fulfilling the growing need of Pakistan's energy sector. The ultimate goal for "Underground Coal Gasification" is to design a new system that can produce sufficient electricity and is relatively cleaner and environment-friendly. The coal reserves that are unfeasible to mine may be utilized by UCG technology. The process can be categorized according to the material injected air-steam injection, oxygen-steam injection. Both categories have their advantages and drawbacks and the process oxygen-steam injection was selected as being more economical. The project being relatively new is still in an experimental and research stage. Thus, the approach of the research throughout is experimental. In this research, formed several models using software like MathCAD and MS Excel that might be useful for further researchers and designers to improve the process.
