South Africa's Sasol Polymers is reportedly expected to substitute the elevated flare at its Sasolburg-based monomer ethylene plant with a new Totally Enclosed Ground Flare (TEGF) by April 2009 to tackle problems including high noise levels, low frequency vibration, smoke pollution and the like. The new TEGF is said to be 30 m octagonal tower surrounded by concrete fencing. According to the company, the injected steam would help increase the velocity of the gases and make possible smokeless combustion. The current elevated flare at the plant was used as a last resort whenever product or feed material could not be used effectively, owing to differences in supply and demand imbalances. The perimeter of the TEGF would be walled with a concrete fence preventing unauthorised entrance, and would act as a barrier against direct wind thus, positively impacting the communities in which the company operates.
