Den Dulk Dairy Farm – EPC: Biogas Ravenna

Ravenna, Michigan

Project Description

A partnership team of Den Dulk Dairy Farm and Grand Valley State University’s Michigan Alternative and Renewable Energy Center in Muskegon contracted with Reynolds and its affiliates to design and build a 250 KW biogas facility.  This project is a demonstration of the versatile application of this sustainable renewable energy system.  A single dairy farm manages this passive technology to produce energy and remove potentially intrusive manure effects from the environment.

Plant Components

  • CSTR Digester features a continuous stir-tank reactor that mixes the heated manure to break it down, thus creating methane gas.
  • H2S Scrubber, manufactured by S&H Umwelt engineering Vertriebs GmbH. Uses Bio-trickling technology for low maintenance.
  • Capstone CR30 Microturbine produces 30 KW of continuous power and 45 KW of thermal energy.
  • CR30 can accept H2S levels as high as 70,000 parts per million.
  • Biogas from the digester facility also powers an 80-kW combined heat and power (CHP) reciprocating engine.
  • 2.8 MMBTU Boiler, Mixing Tank, Gasholder, Biogas Flare.
