Abstract
Disclosed herein is a fracturing unit for hydraulic fracturing having an engine and a fracturing pump connected to the engine through a variable speed torque converter. Also disclosed is a hydraulic fracturing system using multiple fracturing units which are sized similar to ISO containers. A hydraulic fracturing system may also force flow back water, produced water, or fresh water through a heat exchanger so that heat from the fracturing engines can be transferred to these liquids in order to vaporize them. A force cooled fractioning unit then can accept the vapor/steam in order to condense the various components and produce distilled water for re-use in the fracturing process or for release into the environment.
