Author Posts December 7, 2009 at 9:19 pm #2846 Freddy MartinezParticipant What are the government regulations for FCC emissions in your jurisdiction? In NSW, it depends on the age of the unit. Units installed before 1972 required to have opacity < 40% and up to 60% once a day and particulates at < 400 mg/cubic metre. I am particularly interested in regulations for refineries in South-East Asia and Japan. Does anyone have any info or links? …specific regulations seem hard to find. Help would be much appreciated.
