Cameroon Lake Nyos: Prevention not to repeat death of over 1.7K people

In order to avoid this tragedy to happen again, experts are conducting “degassing”. It is a method that experts do to diffuse the deadly gasses.  Degassing columns from rafts in the lake were installed, based on the article from mhalb.pagesperso-orange.fr.

A portion of the description of this method stated:
“The method consists of a pipe set up vertically between the lake bottom and the surface. A small pump raises the water in the pipe up to a level where it becomes saturated with gas, thus lightening the water column; consequently, the diphasic fluid rises to the surface. Therefore, once it has primed the gas lift, the pump is not needed, since the process is self-powered: above the saturation level, isothermal expansion of gas bubbles drives the flow of the gas-liquid mixture as long as dissolved gas is available for ex-solution and expansion.”
