Frequently Asked Questions - The Refinery and the Environment

This is called a flare. The flare allows excess gases that would otherwise build up high, uncontrollable pressure in the system to be burned. The flare is a safety feature, which burns continuously while the refinery is in operation.

  • Noise pollution from operating the plant
  • Possibility of Oil Spills from trucks, ships, pipelines and from the processing plant and tank leaks.
  • Fugitive gaseous emissions from valves, flanges, tanks and process vessel vents.
  • Gas emissions
  • Potential fires due to the presence of highly combustible materials
  • Contamination from sulphur oxides, nitrous oxides and ash emissions from burning HFO/fuel gas in boilers and furnaces.
  • Possibility of hydrogen sulphide emissions, a by-product of hydro-treating which is burnt at the flare.
  • Water pollution by waste water from the process or ground water pollution from leaks and spills.
  • Disposal of municipal waste scrap metal from maintenance, used chemical containers and spent catalyst.
