Development of an advanced mild gasification process
Riley Research Center designed, fabricated, assembled and purchased equipment to erect a skid-mounted 100 LBM/HR continuous mild gasification test unit at the Riley R D Center in Worcester, Massachusetts. Riley partially disassembled the unit and transported the sub-assemblies, parts, and equipment to Western Research Institute, North Site, Laramie, Wyoming. Riley assisted WRI during erection and WRI completed the construction and shakedown of the unit. Crushed Wyoming coal, having a moisture content of 25% to 30%, is fed into an inclined fluidized bed dryer which uses recycled, heated carbon dioxide sweep gas to remove the moisture. The dried coal passes through an inclined fluidized bed gasifier using recycled product sweep gas to remove volatile hydrocarbons and produce char. Western Research Institute has successfully demonstrated that this test unit can produce char from Wyoming coal. This report is a summary description of the design of the 100 LMB/HR continuous mild gasification process demonstration unit with regards to flow process, inclined fluidized beds, and condensers. 20 figs., 10 tabs.
