LIFAC sorbent injection desulfurization demonstration project. Quarterly report No. 3, April--June 1991

Description: LIFAC combines upper-furnace limestone injection followed by post-furnace humidification in an activation reactor located between the air preheater and the ESP. The process produces a dry and stable waste product that is partially removed from the bottom of the activation reactor and partially removed at the ESP.

LIFAC sorbent injection desulfurization demonstration project

Description: In December 1990, the US Department of Energy selected 13 projects for funding under the Federal Clean Coal Technology Program (Round III). One of the projects selected was the project sponsored by LIFAC North America, (LIFAC NA), titled LIFAC Sorbent Injection Desulfurization Demonstration Project.'' The host site for this $17 million, three-phase project is Richmond Power and Light's Whitewater Valley Unit No. 2 in Richmond, Indiana. The LIFAC technology uses upper-furnace limestone injection with patented humidification of the flue gas to remove 75--85% of the sulfur dioxide (SO{sub 2}) in the flue gas. In this report, progress for the period July--September 1991 is covered.

LIFAC Sorbent Injection Desulfurization Demonstration Project

Description: LIFAC combines upper-furnace limestone injection followed by post- furnace humidification in an activation reactor located between the air preheater and the ESP. The process produces a dry and stable waste product that is partially removed from the bottom of the activation reactor and partially removed at the ESP. In November 1990, after a ten (10) month negotiation period, LIFAC NA and the US DOE entered into a Cooperative Agreement for the design, construction, and demonstration of the LIFAC system. This report is the fifth Technical Progress Report covering the period October 1, 1991 through the end of December 1991. Due to the power plant's planned outage schedule, and the time needed for engineering, design and procurement of critical equipment, DOE and LIFAC NA agreed to execute the Design Phase of the project in August 1990, with DOE funding contingent upon final signing of the Cooperative Agreement.

LIFAC Sorbent Injection Desulfurization Demonstration Project. Quarterly report No. 6, January--March 1992

Description: The LIFAC technology has similarities to other sorbent injection technologies using humidification, but employs a unique patented vertical reaction chamber located down-stream of the boiler to facilitate and control the sulfur capture and other chemical reactions. This chamber improves the overall reaction efficiency enough to allow the use of pulverized limestone rather than more expensive reagents such as lime which are often used to increase the efficiency of other sorbent injection processes. Sorbent injection is a potentially important alternative to conventional wet lime and limestone scrubbing, and this project is another effort to test alternative sorbent injection approaches. In comparison to wet systems, LIFAC, with recirculation of the sorbent, removes less sulfur dioxide - 75--85% relative to 90% or greater for conventional scrubbers - and requires more reagent material. However, if the demonstration is successful, LIFAC will offer these important advantages over wet scrubbing systems: LIFAC is relatively easy to retrofit to an existing boiler and requires less area than conventional wet FGD systems; LIFAC is less expensive to install than conventional wet FGD processes; LIFAC`s overall costs measured on a dollar-per-ton S0{sub 2} removed basis are less, an important advantage in a regulatory regime with trading of emission allocations. LIFAC produces a dry, readily disposable waste by-product versus a wet product; and LIFAC is relatively simple to operate.

LIFAC Sorbent Injection Desulfurization Demonstration Project

Description: In December 1990, the US Department of Energy selected 13 projects for funding under the Federal Clean Coal Technology Program (Round III). One of the projects selected was the project sponsored by LIFAC North America, (LIFAC NA), titled LIFAC Sorbent Injection Desulfurization Demonstration Project.'' The host site for this $22 million, three-phase project is Richmond Power and Light's Whitewater Valley Unit No. 2 in Richmond, Indiana. The LIFAC technology uses upper-furnace limestone injection with patented humidification of the flue gas to remove 75--85% of the sulfur dioxide (SO[sub 2]) in the flue gas. The work performed during this period (July--September 1992) was consistent with the revised Statement of Work (Scope Increase) and the approved schedule change contained in the Cooperative Agreement. During this period, emphasis was placed on startup and commissioning activities and baseline testing. Work was conducted under the three tasks comprising the Operations Phase. Summary of the work performed under these tasks is given.
