Gas Drive Global LP was retained by the Region of Peel to supply a turnkey design-build digester gas fuelled cogeneration system, rated 1.4 Megawatts, that was installed at the Clarkson Wastewater Treatment Plant facility. Gas Drive in turn retained Golder to provide technical support and detailed engineering necessary to install a digester gas fuelled cogeneration package, complete with gas conditioning module, and exhaust waste heat recovery boiler. Using the biogas produced by anaerobic digesters at the plant to generate electricity and useful heat enables the WWTP to decrease emissions

Golder’s work scope included the following:

• Detailed design engineering for the biogas conditioning process;
• Component specification for the gas conditioning module;
• Developed the process and instrumentation drawings and process control narrative (PCN)
  for the gas conditioning module and combined heat and power system;
• Ensured the overall design for complied with the requirements of CSA B149.6-11 (Code for
  Digester and Landfill Gas installations) and good engineering practice;
• Participated in Hazard and Operability review meetings and risk assessment for the
  cogeneration system;
• Liaison with the Technical Standards and Safety Authority (TSSA) for approval of the gas
  treatment system and gas valve train components;
• Conducted final quality control visit at factory after manufacturing; and.
• Perform final review and sign off for the cogeneration system

Work involved consistent project communications with Gas Drive’s project manager, electrical engineer and programmer along with the site construction managers at the Clarkson WWTP. In addition, Golder was retained to provide construction oversight for the mechanical installation of the gas treatment package, the combined heat and power (CHP) package and the interconnect pipework between the two systems.
