A power plant was set up on the Montreal domestic waste landfill site (former Miron quarry) in 1996. This plant is powered by biogas given off during waste decomposition. The biogas is composed chiefly of methane. Due to the location of the plant near residential zones, noise was given special consideration during the engineering phase in order to ensure compliance with the applicable regulations. At commissioning, the plant was found to be compliant in continuous operation mode. However, the steam shedding operations, required during start-up and shutdown cycles as well as in emergency situations, greatly exceeded the applicable standards, drawing complaints from the citizens. The noise was caused by the rapid release of steam into the atmosphere through a globe valve that discharged to the outside. The installation of a muffler on this valve brought the noise emissions within the applicable standards. However, the performance was less than anticipated based on the manufacturer's data. It should also be concluded that sound sources of a sporadic nature are just as important as those associated with continuous operations. All the operating conditions of a power plant must be considered in the detail engineering of a project in order to ensure its compliance with the applicable acoustic standards.Downloads
