'Excessive smoke' spotted coming from Jurong Island could be due to flaring
STOMPer Paul reported seeing 'excessive smoke' from Jurong Island today (Oct 28).
He says:
"Excessive smoke from Jurong Island?
"This was seen in the evening...typically there is no smoke but today excessive smoke was emitted creating a huge plume."
STOMP understands that this may just be "flaring", performed at refineries to burn off excess gas, so that pressure does not build up in the equipment.
The smoke emitted is composed of mainly water and carbon dioxide. In Singapore, all flaring is subject to regulatory limits.

JUST flaring ? Depending on the composition of the fuel being flared away, the process can produce different greenhouse gases & hazardous pollutants, such as sulphur dioxide (SO2), nitrous oxides (NOx), carbon monoxide (CO), methane (CH4), non-methane volatile organic compounds (NMVOCs) & carbon dioxide (CO2) -- not to mention uncombusted smoke particles.
Unfortunately, flaring is a relatively common practice at oil refineries here. As residents would know, the air quality in southwestern S'pore is actually not very good.
