FIELD: technological processes.
SUBSTANCE: system is described that provides a proppant for mixing in a fluid stream from a liquefied gas using an eductor to produce a proppant slurry, which is effectively regulated by a control valve system and the associated PLC controller. Said system ensures the operation of the system at various static pressure values and keeps the proppant completely flowable throughout the entire fracturing operation.
EFFECT: technical result is higher efficiency of controlling the concentration of proppant in the hydraulic fracturing fluid.
