Sand X Flowback Process When the flowback enters the Sand X, the gas pressure is released into the frac tank, and the hydrocarbons, water and sand fall into the hopper There is a screen that catches larger pieces of debris, such as plugs, etc for observation The mixture begins to separate, and as the sand falls through the water, any hydrocarbons on the surface of the granules are displaced, and float to the top of the mixture

Sand X Flowback Process - Continued The liquid rises to the hopper overflow and falls into the tank The sand settles into the auger, and by the time it is pushed out of the top of the hopper, it is merely damp According to independent test data, the hydrocarbon and chloride levels are safe enough to be incorporated into the environment, eliminating the expense of sand disposal
