Abstract: An apparatus and method for delivering a thickened fluid mixture, including a CO2 recapture system. The apparatus including a proppant storage vessel and a fracturing fluid storage vessel providing a continuos supply of a proppant material and a fracturing fluid to a mixing apparatus. The mixing apparatus configured to output and deliver a thickened fluid mixture of the proppant, the fracturing fluid and a thickener agent at or above the fracturing fluid blending pressure to a high pressure pump assembly. The high pressure pump assembly configured to deliver a high pressure thickened fluid mixture to one or more downstream components at an injection pressure. The apparatus including a CO2 recapture system configured to recapture an exhaust stream from the one or more downstream components and/or other CO2 output sources, and provide a purified and liquefied CO2 fluid stream to the fracturing fluid storage vessel. The apparatus configured for continual operation.
