(37d) Cleaner Conversion of Coal to Liquid Fuels with Proven Gasification Technology:

Gasification is typically conducted at high temperature and high pressure with aid of gasification agents such as oxygen/steam to generate syngas that is rich in CO and H₂.  CO and H₂ can be used as an intermediate for a wide variety of products including: chemicals, fuels, and metals. The high pressure reduces the volume of the syngas and makes it relatively simpler to remove potential pollutants. Traditionally sulfur compounds from coal are captured with lime and results in a large amount of solid and liquid waste that needs to be disposed off. In gasification process, sulfur compounds can be captured and discarded as sulfur rather than as calcium sulfate, thereby reducing the amount of solid waste to landfill. Also, the high pressure makes it easier to capture CO2 reducing the amount of greenhouse emissions. The high oil price in recent years has increased the demand for CO2 for EOR. This has resulted in a number of projects now seeking to capture CO2.  This presentation will discuss some recent projects at KBR that involve proven gasification technologies. The advantages of integrating proven gasification technologies with technologies proven in oil and gas sector to produce liquid fuels from coal will be discussed.
