Clean Fracturing System Using CO2 and Steam

The patent removes harmful chemical contaminants from the fracturing process by using only water and sand as fracturing agents. This extraction of toxic substances resolves the contradiction by maintaining fracturing effectiveness through mechanical means while eliminating environmental pollution and water contamination associated with chemical usage.

The patent creates an inert environment by using clean water and sand instead of reactive chemical contaminants. This inert approach prevents harmful chemical reactions and contamination while still achieving the desired fracturing effect, thereby resolving the contradiction between effectiveness and environmental harm.

The patent extracts toxic chemicals from the fracturing fluid composition, leaving only water and sand. This removal enables water recycling because the remaining components are non-toxic and environmentally benign, resolving the contradiction between maintaining fracturing capability and preserving water recyclability.

The patent implements a system where water and sand can be discarded after use and easily recovered through filtration and separation processes. The absence of toxic chemicals makes recovery feasible and economically viable, thereby resolving the contradiction between using sufficient water for effective fracturing and enabling water recycling.

The patent extracts harmful chemical agents from the fracturing process and replaces them with water and sand. This extraction maintains the ability to break up mineral-containing material through mechanical stress while eliminating the generation of harmful factors that would contaminate underground water sources.

The patent converts the potentially harmful interaction between chemicals and groundwater into a beneficial outcome by using only water and sand. The fracturing process still achieves effective material breakdown, but the absence of toxic chemicals transforms what would have been contamination into a clean, sustainable process.
