A TEC Company Brochure

1The specialisT in cemenT process Technology and engineering32a Tec - World leader in cemenT pyroprocess Technology.Increasing energy costs, stricter environmental regulations, increasing production costs and intense global competition are the driving forces for change in the cement industry.The scarcity of energy sources and the increasing concern about chemical additives require a constant optimization of the cement industry´s pyro-processes and grinding processes.In the past ten years A TEC has pioneered the development of state of the art technologies, which are patented worldwide, to optimize the entire pyro-process. This was realized through high investments in our own products and the consistent attention to improvement of the entire pyroprocess.Worldwide unique process know-how paired with strategic partnerships in various process technologies provide our clients with the global leading pyro-process technology in the cement industry.A TEC runs the world’s most advanced Pilot Plant for preheater and cyclone optimization in the A TEC Process Centre Austria. This is the guarantee that only highly engineered products and break through process technologies are employed in projects.The result: A TEC supply covers a range from special solutions to turn-key pyroprocess plants. Drastic reduction of energy costs, significant increases in efficiency and the fulfillment of environmental requirements become reality.A TEC Pyroprocess Engineering: Significant efficiency improvements Drastic cuts in energy consumption Compliance with environmental limitsA TEC Consulting Studies for Plant Engineering Economic analyses Project Managementprocess centre austriaThe world’s most advanced preheater and cyclone Pilot Plant in the world.Constant refinement of existing patents as well as development of new products and processes ensure that A TEC stays in the global leading position in cement pyroprocess technology.54OPTICOALThe HURRICLON® 3 ST guarantees the high-est possible dust separation from the preheater exhaust gas for maximum efficiency of the coal mill and the reduction of energy consumption.HURRICLON® 3 CT + ST and HURRIVANE® 3Improve efficiency and pressure drop by up to 50% compared to conventional cyclones.residual dust contentCyclone +Type CT Type STpressure dropCEMENTIZILLO Fanna3rd GenerationWorld Leader in Cement Pyroprocess TechnologyThe Technical masTerpiece For eFFiciency increase and redUcTion oF energy cosT.Pressure Drop Reduction and Efficiency Increase.Optimization becomes reality with the worldwide paten-ted high-performance cyclone HURRICLON® 3 and the world’s best pressure drop reduction tool, the HURRI-VANE® 3, both from A TEC.A TEC develops a tailor-made concept for optimization of energy demands, efficiency and fulfillment of environ-mental requirements.eFFiciency increase WiTh loWer energy cosTs.The weakest Link in the Chain determines its overall Strength.For A TEC, process optimization means to look at the whole pyroprocess, to calculate optimization potentials and to intervene at the right points.A TEC’s longtime experience and more than 600 successfully completed projects prove a high degree of competence and technological leadership.Our process engineers are constantly developing existing and new products and processes in our worldwide unique Pilot Plant.World Leader in Cement Pyroprocess TechnologyA TEC SPLASH BOXThe V-shaped chamber dispenses cement-meal evenly to optimize heat exchange. 6A TEC PENDULUM FLAPFor maximum Tightness and higher Performance.Easily adjustable counterweights ensure 100% tightness and process reliability.
