To optimize the gas treatment centre (GTC) of Potline 8 at the Jebel Ali smelter in Dubai, UAE, in mid-2017, FLSmidth Hamburg (FLS) was commissioned by Emirates Global Aluminium (EGA) to substantially lower the dust concentration at the entrance to the GTC. The 24 vent domes of the two pneumatic conveyor systems for the transport of secondary alumina to the 44 aluminium electrolysis cells (pots) were identified as the prin- cipal source of emissions. The following report describes the requisite studies of the system as well as in the test centre and delineates the measures undertaken to reduce emissions.
