Ciment de Sibline is the third largest clinker and cement manufacturer in Lebanon. The plant has an annual production capacity of 12 thousand tons of cement and operates two dry process kilns. For energy saving and utilization of grate cooler waste gases for raw materials drying, the company decided to replace the existing two separate dedusting systems – a multicyclone on the cooler exit and an ESP for mill and preheater kiln gases - by a new common bag filter. This bag filter will dedust both the kiln/raw mill gases and the clinker cooler excess air.
Intensiv-Filter received the order for the turn-key supply, including complete engineering, supply of mechanical and electrical equipment, assembly, commissioning, final inspection and approval of the plant.
The filter of the series type ProJet mega® will be arranged as a double-row filter. After the disassembly of the old ESP, which will also be carried out by Intensiv-Filter, the filter will be installed on the existing footprint of the old ESP. The volume flow amounts to max. 310.000 m³/h a.c. at a dust load of 33 g/m³ n.c. To reliably clean the raw gas at a maximum operating temperature of 200 °C, the ProJet mega® bag filter is equipped with filter bags made from fiberglass fabric with PTFE membranes. The bag length amounts to 8 m. The patented cleaning control system JetBus® controller with the pressure-controlled cleaning system ECO will ensure an energy-efficient operating and a constantly optimized dust removal. Cleaning will be executed in the semi-offline mode with low pressure technology.
