CALES DE PACHS Calcium Hydroxide CL-90S production process starts with analyzing the lime is stored in different stock tanks depending on its quality and its final application. One of these tanks is used for providing the hydration part of the plant with calcium oxide, which with the addition of water, transforms itself into slaked lime or calcium hydroxide. It is the responsibility of our Laboratory to analyze the different purities and fineness that we are producing, to control the lime that is used in the building industry by conducting daily tests on the volume stability of our slaked lime and so ensuring perfect hydration. Also, our calcium hydroxide is saturated with water, which activated with a dispersant to keep it in suspension, produces a milk lime with up to 45% concentration, which we have called GELCAL®. This is a registered product primarily targeting small users within the environmental protection. Besides, we are currently developing a calcium hydroxide with a high specific surface for flue gas treatment.
