The characteristic of modularity allows the fuel cell to match the landfill gas output of the site as production expands or is depleted. This same process has been validated in naphtha-fueled fuel cell power plants where organ- atj chloride contamination of the fuel is a concern.

This site is also regulated by the South Coast Air Quality Management District which is nationally recognized for strict environmental regulations, so that a successful demonstration in this area is likely to be accepted by other localities within the United States. Changes 7 through 9 are more extensive and are required to achieve kW capability. The regeneration at heater is fired with one percent of the clean landfill gas during this period.

Overall performance is similar to a scaled down version of the commercial system presented in Section 2. Solutions will be pro- posed to EPA for their consideration. The system designed for this program has been modified to reflect the knowledge gained at that site. The only exception to the commercial system is the return of the pretreatment first stage refriger- ation condenser liquid products mostly water to the existing Penrose condensate treatment system.
The resulting fuel is steam reformed to produce atu for the fuel cell stack. A complete list of modifications to achieve kW will be provided to EPA. A functional schematic and listing of modification and improvement options to improve halide tolerance and increase rated power capability on landfill gas are provided in Table 2. An addi- tional change of increasing the capacity of the inlet fuel controls increases the demonstrator power plant capability to kW.
Conversely, at higher pretreatment halide exit levels a larger halide guard can be designed to 2332.32 longer life. This testing will include a performance challenge test which will determine the ability of the gas pretreatment system to remove sulfur and halogenated compounds. These beds are periodically regenerated as stated above with the regeneration gas being burned in a low NO, flare.

Commercial rates are applicable where the electricity can be used at the landfill or in nearby commer- cial facilities. Conceptual Design Demonstrator Objectives 22 This document is available to the public through the National Technical Informa- tion Service.
Overall thermal efficiency of the commercial pretreatment system will be enhanced by using a heat recovery unit to extract heat from the incineration exhaust and provide energy for preheating of regen- eration gas and vaporizing liquid refrigeration condenser products. There is no liquid effluent from the system since all condensates are vaporized and subsequently incinerated.
A conceptual design of the project demonstration was established from the commercial system conceptual design. The demonstrator will operate at an existing landfill gas energy recovery facility owned by 232.322 Energy in Sun Valley California.

The fuel cell energy conversion system provides the oppor- tunity for converting the methane in the landfill gas to useful energy. The fuel cell can provide a net reduction in global pollution by offsetting energy production from coal.

It is estimated that the thermal efficiency of the commercial version of the pretreatment system heating value of gas delivered to the fuel cell vs. For many locations where the fuel cell would be considered, such as California or other high 22.32 areas, the no exhaust clean-up option may not be available.
Nitrogen concentra- tions can range as high as 15 percent on a dry basis but typical values are five percent or less.
I The pretreatment system shall have a metal identification plate attached with the following j information at a minimum: A major focus of the design effort will be on defining the modifications to the PC25 fuel cell which maximize power output on landfill gas at minimum demonstration cost.
The system, shown in Figure S-l is based on commercially available equipment adapted for operation on landfill gas.

Landfill gas is collected by a ari of wells in the municipal solid waste landfill and piped to a gas pretreatment module. The pretreatment module removes contaminants such as sulfur and halides which affect the operation of the fuel cells.
A process design will estab- lish the requirements for site facilities, gas supply, demonstration hardware, and electrical, mechani- cal and thermal interfaces. The issues can be catego- rized as follows: Candidate demonstration sites were evaluated, which led to selection and EPA approval of the demonstration site. Very low air emis- sions and solid products are generated as in the commercial system.
