Shanxi Jincheng Anthracite
Coal Mining Company

Location:
Shanxi, People's Republic of China

 

Shanxi Jincheng Anthracite Coal Mining Company (JMG) has constructed a 120 MW coal mine methane (CMM) fired power plant. CMM contains about 40 percent methane. The power plant will incorporate the following principal components:

  • A pressurization station and two 30,000 m3 CMM gas holders;

  • Sixty 1.8 MW Caterpillar 3520 reciprocating engine/generators;

  • Twelve waste heat recovery boilers; and

  • Four steam turbine/generators.

The project cost is about US $200 million. Revenue produced by the project will consist of avoided power purchases, sale of excess power to the local utility company, and the sale of certified emission reductions (CERs) under the Clean Development Mechanism.

JMG engaged SCS Energy to provide technical assistance in development of the project.  SCS’s responsibilities included: design review; assistance in procurement; assistance in monitoring contractors and equipment suppliers; and assistance in plant performance testing.

The project commenced operation in June 2008.

University of New Hampshire Gas Plant

Owner:
University of New Hampshire

Location:
Rochester, New Hampshire

 

SCS has been engaged by the University of New Hampshire (UNH) to design, construct and operate a 7,500 scfm (10.8 mmscfd) landfill gas processing facility. The facility will convert raw landfill gas into a clean, Btu-enhanced product suitable for firing in UNH’s existing combined cycle cogeneration facility, and for other on-campus uses. The product gas will have a minimum energy content of 810 Btu/ft3 and will be free of hydrogen sulfide, siloxane and other problematic compounds found in landfill gas.  The project will begin operation in February 2009.

Principal components of the landfill gas processing facility will include:

  • Compression and refrigeration;

  • Non-regenerative hydrogen sulfide removal;

  • Temperature swing adsorption;

  • Pressure swing adsorption;

  • Thermal oxidizer;

  • 3.2 MW of on-site power generation; and

  • Two standby flares.

SCS also investigated the technical and economic feasibility of liquefaction of a portion of the product gas to produce up to 10,000 gallons per day of liquefied methane gas (LMG), and investigated the feasibility of adding a nitrogen removal step to the plant.

 McCommas Bluff Gas Plant

Owner:
Dallas Clean Energy

Location:
Dallas, Texas

 

McCommas Bluff is one of the largest projects in the United States that produces pipeline quality gas from landfill gas.  The inlet capacity of the plant is 6,500 scfm (9.4 mmscfd).  The plant produces gas having a minimum energy content of 970 Btu/ft3.

Principal components of the plant are as follows:

  • Raw landfill gas compression (to 120 psi);

  • Dehydration;

  • Temperature swing adsorption for volatile organic compound (VOC) removal;

  • Pressure swing adsorption for carbon dioxide removal; and

  • Thermal oxidization.

SCS has been responsible for operation and maintenance of this facility since June 2005.

SCS is currently implementing a plant upgrade program on a design/construct basis.  Principal components of this program include:

  • Installation of pre-compression hydrogen sulfide removal equipment;

  • Replacement of the existing engine drive compression equipment (landfill gas, carbon dioxide rinse gas and product gas) with electric drive compression equipment;

  • Replacement of the thermal oxidizer; and

  • Replacement of the plant’s SCADA system with SCS’s proprietary iSCADA technology.

SCS is also designing a 4,200 scfm (6.0 mmscfd) plant expansion.

The McCommas Bluff Landfill is owned and operated by the City of Dallas.  It is one of the largest landfills in the United States, and accepts about 7,000 tons/day of waste.  Landfill gas is collected by over 300 vertical extraction wells.
