New order of Intensiv-Filter in Lebanon

Published 02 March 2012


Ciment de Sibline is the third largest clinker and cement manufacturer in Lebanon. For energy saving and utilisation 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 turnkey 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. 310,000m³/h a.c. at a dust load of 33g/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 8m. The patented cleaning control system JetBus® controller with the pressure-controlled cleaning system ECO will ensure an energy-efficient operating and a constantly optimised dust removal. Cleaning will be executed in the semi-offline mode with low pressure technology.
