Qatar: Qatar National Cement has signed a provisional acceptance certificate with France’s Fives for the construction of new production line at the Umm Bab plant. The new 5000t/day line is the fifth at the site. It covers the whole equipment from the raw material preparation to the cement dispatch. Previously Fives and Qatar National Cement collaborated on lines two, three and four at Umm Bab.

Qatar: France’s Fives FCB has released more information about its project to build a fifth production line for Qatar National Cement at its Umm Bab plant. The new 5000t/day clinker line was ordered in April 2014 and Fives has been responsible for the supply of a complete production line from raw material preparation to cement despatch. The new line is expected to be commissioned in the first half of 2018.

The line uses natural gas for fuel. Raw material preparation includes a 1000t/hr double impact rotor crusher for limestone, clay or shale, a gamma ray analyser, two limestone storage silos of 30,000t and two shale and clay storage siloes of 10,000t. For raw meal grinding the line will use a 440t/hr FCB B-mill with a diameter of 5.6m, a length of 21.2m and a power of 6600kW. It also has a FCB TSV 7500 Classifier BF.

The 5000t/day kiln consists of a five-stage single string FCB Preheater with low pressure drop cyclones, a FCB Zero-NOx Precalciner with a diameter of 5.2m fitted with a Pillard PRECAFLAM burner, a three piers FCB rotary Kiln with a diameter of 4.8m and length of 76m, a Pillard NOVAFLAM burner for rotary kiln, a clinker grate cooler with an active area of 112m², an electrostatic precipitator for cooler dedusting, a Pillard ROTAFLAM burner as auxiliary burner and a Pillard HeatGen Systems for hot gas generation. The kiln line also includes Fives TGT UP Filters for the kiln and alkali bypass. The line has a 40,000t clinker storage silo.

Cement grinding comprises two FCB B mills with a capacity of 115t/hr. These have a diameter of 4.6m, a length of 14m and a power of 4200kW respectively. Cement grinding also includes Two Fives SONAIR Filters, two FCB TSV Classifiers and two Fives SONAIR Filters. Cement storage consists of two 20,000t silos.

Finally, cement packing and dispatch includes four truck loading systems with a capacity of 250 - 300t/yr each and one big bag loading station with a capacity of 30t/hr.

The project follows collaboration between Fives and Qatar National Cement on lines two, three and four at Umm Bab.

Qatar: Qatar National Cement Company (QNCC) plans to open its fifth cement plant in the first half of 2018. The move will increase its cement production capacity of 5500t/day, according to the Qatar Tribune newspaper. However, its sales of cement fell slightly to 3.4Mt in 2017 from 3.7Mt in 2016.

The cement producer’s sales revenue fell by 9.6% year-on-year to US$283m in 2017 from US$313m in 2016. Its net profit decreased by 31% to US$90m from US$130m. The company blamed the falling profit on a poor local economy causing poor demand and a reduced selling price since April 2017.
