The fifth clinker production line at Qatar National Cement Co.’s Umm Bab plant is now producing at a steady rate, helping to cover the rising demand from the Qatari infrastructure sector. The new line was supplied by Fives and has capacity of 5000 tpd.
Industrial and performance tests for the raw meal grinding, homogenising, limestone crushing, and pyroprocess sections were completed in 1Q18. The new line is the fourth to be supplied by Fives to Umm Bab, after lines two, three and four were implemented by Fives.
The initial contract was signed in April 2014 and included the full turnkey supply of the production line, including the supply of Fives proprietary process equipment and the integration of all other non-process equipment, as well as civil design, civil works, erection and commissioning.
Raw meal grinding at Umm Bab is by 5.6 m dia. x 21.2 m FCB B-mill with installed power of 6600 kW and an FCB TSV Classifier. Raw meal grinding capacity is 440 tph.
The pyroprocess line includes an FCB Preheater, FCB Zero-NOx Preca precalciner with Pillard PRECAFLAM burner, a three-pier FCB 4.8 m dia. x 76 m rotary kiln with a Pillard NOVAFLAM burner, TGT UP filters for both kiln and alkali by-pass, Pillard ROTAFLAM auxiliary burner, and Pillard HeatGen Systems hot gas generator.
The pyroprocessing line also includes an 112 m2 clinker grate cooler and electrostatic precipitator for cooler dedusting.
Cement grinding is done on two 4.6 m dia. x 14 m FCB B-mills with 4200 kW installed power. The grinding line is also equipped with FCB TSV Classifiers and Fives SONAIR Filters. The plant has cement grinding capacity of 2 x 115 tph.
The plant also includes 40 000 t clinker storage silo capacity and two 20 000 t cement storage silos. Packing and dispatch is done by four truck bulk loading systems and one big bag loading station.
The four Fives production lines at Umm Bab have a combined capacity of 21 000 tpd of cement. Qatar has seen significant increase in its cement demand in recent years due to the various infrastructure projects, which includes construction related to the 2022 Football World Cup.
Correction: a previous version of this article stated that the Umm Bab plant was not producing at a steady state instead of now producing at a steady state. Our apologies.
