“This new module will enable us to design condensate polishing more reliably and precisely, especially in power plants,” explains Hans-Jürgen Wedemeyer, technical marketing manager in Lanxess’ LPT business unit.
The software module can be used to model H/OH cycles in the presence of various alkalization reagents. Lanxess says this provides an extremely high level of corrosion protection for the plant with maximum cost-effectiveness.
LewaPlus enables the design of both separate ion exchange (IX) reverse osmosis (RO) plants and combined RO/IX systems. The software currently offers five other components in addition to the condensate polishing module. There is one each for modeling demineralization using ion exchange or reverse osmosis. Combining this with the mixed bed module enables the design of a system for treating feed water for water-steam cycles, for example.
The demi check module enables the user to check existing make-up water treatment systems for their cost-effectiveness based on various input parameters such as measured concentrations, specific plant characteristics and regenerative behavior. If necessary, the module can also be used to optimize the systems.
Finally, LewaPlus has a module for modeling softening and decarbonization processes. These are particularly important for applications in the home, for treating drinking water and in the food industry. Power plants with low-pressure cycles also require these kinds of process steps.
