Chrome Lignite
Chrome Lignite is selected lignite material which has been solubilized with caustic soda and chromium salt. It is a fine dry free-flowing powder and readily disperses in the drilling mud. Chrome Lignite is highly soluble and is stable at high temperature. It exhibits tolerance for soluble contaminants. It was more temperature-stable than plain lignite in clay-based water muds. The recommended treatment of Chrome lignite as a deflocculate and as an emulsifier is 1.0 to 3.0 ppb and as a filtration control agent: 2.0 to 8.0 ppb.
