Lurgi has been using this type of rotary kiln for the magnetizing roasting of haemetite iron ores, for the reduction of nickel ores, for the volatilization of non-ferrous metals, such as zinc (Waelz process), and for pyrite roasting. From that time on these kilns have also been equipped with several types of …
Apr 27, 2010· Researchers have been looking for ways to remove the SSP stage. For example, Lurgi Zimmer has developed a direct process for making the PET bottle preforms without the SSP step. It is based on an integrated process that produces a high viscosity melt from which the chips can be fed directly to the preform unit.
The Lurgi low pressure system was used as a reference in the plant to be designed. The limitation of the Lurgi process only applies to plants that exceeds the capacity of the proposed process hence that disadvantage does not affect the process. A typical lurgi methanol process is shown on the diagram below. Fig 2.1Lurgi methanol process

Aug 27, 2012· Several process-control issues can individually or collectively cause the problem. The process water may be too hot. Lower the temperature to adequately quench the surface of the pellet. Another cause may be low water flow, which can contribute to pellets moving slowly out of the cutting chamber, resulting in agglomeration.
