SCOPE OF WORK

INNOVA conducted acoustic surveys during start-up, steady state and shutdown conditions of the ammonia and urea plants. INNOVA then designed, supplied and installed the necessary noise mitigation measures including; steam vent silencers, acoustic barrier, and a furnace stack silencer. 

ACOUSTICAL REQUIREMENTS

49 dBA at the nearest sensitive area (NSA) approximately 750 meters (2,460 ft.) away

NOISE SOURCES

Steam vents, ventilation exhaust for the compressor building and the furnace exhaust stack

SILENCING SOLUTIONS

INNOVA installed steam vent silencers, a bullet-type stack silencer and an absorptive acoustic barrier wall along the compressor building ridge vent.

UNIQUE PROJECT HURDLES

This was a fast-track project that had to be completed during a scheduled plant shutdown.
