Membrane separation, eliminates the thermal degradation and chemical changes that can occur in distillation or evaporation. For this reason, membrane separations are suitable for separating temperature-sensitive products. In addition, they are often less energy intensive than conventional separation processes, and the separation systems are modular, allowing very easy scaleup of processes.

This fracking fluid is called slickwater. The sand (or other solid materials) are called proppants and are added to prop open the fractures that form under pressure. They are deposited in the fractures to keep them from closing up thereby ensuring that gas and oil can continue to flow freely out of rock fractures even after pumping pressure is released.

2. How is “frac ,flowback,” different from produced water? Hydraulic ,fracturing, (“fracking”) is the injection of about two million gallons of water and chemicals at a time into a well, to open up the gas or oil trapped in shale deep below. This one-time injection is called a “frac job”. A well may require up to 40 frac jobs.
