Turkey: Austria's A TEC Production & Services GmbH has been awarded a contract by Çimentaş Elaziğ for its plant in Elaziğ Province. The contract covers engineering for upgrades and efficiency optimisations of its preheater tower.
The scope of modifications comprises the redesign of all four cyclone stages, riser ducts and related equipment. The project target is to reduce the total preheater pressure drop by 25% and to increase production capacity by at least 8% on a sustainable basis.
The project will be executed in two phases. The first stage modifications were completed in May 2014, the second phase work is due to be completed shortly, while the third and fourth stages are due for completion in 2015. Phase one resulted in a sustainable production increase of 8% and a pressure drop reduction at the fan inlet by about 19%. Based on the phase one results, it is expected that the pressure drop before the fan will be reduced beyond the target figures after completion of phase two, which will allow higher production at less specific power consumption on the fan than initially targeted.
