 Context: The Manipur government has formed a three-member committee to conduct a thorough investigation into a fuel leak from a power plant (Leimakhong Power Station) in Imphal Valley, which subsequently spilt into a nearby stream that converges with the Imphal River. The heavy fuel oil, a byproduct of crude oil distillation, poses environmental concerns.

 

About HFO:

Heavy fuel oil (HFO) is a residual fuel that’s a byproduct of the distillation of crude oil. It’s also known as bunker fuel or residual fuel oil.

HFO is a tar-like substance that’s used to generate heat and motion. It’s primarily used as a marine fuel. 

 HFO is toxic and has a boiling temperature of 350–500°C. It has a higher viscosity than diesel. The quality of HFO depends on the quality of the crude oil used in the refinery. 

HFO is widely used because it’s about 30% cheaper than alternatives.

 

About Imphal River:

It originates from the northern hills of Karong in Senapati District and is joined by the Iril River at Lilong, which is a significant watercourse draining the central plain. The river, along with others, contributes to the formation of swamps and lakes, including the renowned Loktak Lake.
