The ESG has received several reports of continuous yellow fumes emanate from the LNG Power Station. The group immediately contacted environmental authorities with the first, recent report, filed last Thursday. Since then more reports have come in of continued fumes and no explanation has been given. Nitrogen Dioxide emissions responsible for the sight of yellow plumes at the LNG plant in the past are usually controlled via SCR treatment 1. Prolonged periods of such plumes suggests abnormal operational activity. This pollutant is tightly controlled because of its impacts on public health.
The group appreciates that blips in the system as complex and technical as this installation happen but sincerely hopes the current situation will be rectified and explanations supplied to the public forthwith.
Yellow fumes explained:-

Yellow plumes can sometimes be observed at the exhaust of diesel and natural gas generators during certain operating conditions (see Figure 1). This is a visible representation of nitrogen dioxide (NO2) present in the exhaust gasses from an engine. Utilizing Selective Catalytic Reduction (SCR) technology such as the ecoCUBE®, NO2 is reduced to colourless and harmless nitrogen gas and steam, and then released into the atmosphere. When an SCR system is operational, there should be no visible yellow plume as a large majority (> 90% typically) of the NOx present in the exhaust stream is destroyed.
