Industrial fuel gas demonstration plant program. Overall program plan for Task IX. Technical support. Volume I. Plan, schedule and organization. (Deliverable No. 46)

The Industrial Fuel Gas Demonstration Plant Program (MLGW/DOE), Contract ET-77-C-01-2582, has been slowed due to lack of an adequate data base for demonstration plant design. This design data base is to be developed by Institute of Gas Technology (IGT) at their U-GAS pilot plant. While initial data and operating results from the pilot plant have been encouraging, ash-balanced operation with coal using the technique of ash agglomeration has proven to be more difficult than originally envisioned. Ash must be removed from the gasifier at the same rate as it is being fed to achieve overall ash balance. Adequate ash balance has been achieved by bed withdrawal, but in order to attain high levels of carbon utilization, preferential removal of high-ash material from the gasifier will be required. It is the conclusion of all parties involved that the operating parameters necessary to achieve ash balance and high carbon utilization must be demonstrated at the pilot plant level before a full scale demonstration plant design effort is started. IGT, with guidance from the program Steering Committee and assistance from the Technical Sub-Committee has re-evaluated its efforts under Task IX, Technical Support. With a critical assessment of data generated to date and an analysis of demonstration plant design data need formulated by Foster-Wheeler Energy Corporation, IGT has developed the attached program to meet the demonstration plant design data requirements. The time required for execution of this revised program is seven months. The cost of completing the program is $1,100,000 over and above that originally budgeted for Task IX. The success of the IFG Demonstration Plant Program depends upon results achieved under this seven month program
