Abstract
A refueling system for supplying fuel to hydraulic fracturing equipment. The refueling system having a main fuel source and at least one pressurization unit. The pressurization unit having a pump, a motor, a motor fuel source, a supply coupling device and a return coupling device. The refueling system having sensors in the one or more supply fuel lines and in the one or more return fuel lines for receiving flow rate information and pressure information, wherein the flow rate information and pressure information is compared to preset limits and a message is transmitted when the flow rate information and pressure information falls below or exceeds the preset limits to adjust rates of operation.
Claims15
A refueling system for supplying fuel to hydraulic fracturing equipment, the refueling system comprising:
- a) a main fuel source fluidly connected to a plurality of hydraulic fracturing equipment, each piece of hydraulic fracturing equipment providing downhole fluids to a well for fractionation of the well;
- and
- b) at least one pressurization unit fluidly connected to the main fuel source, the at least one pressurization unit comprising:
- (i) a motor fuel tank containing fuel;
- (ii) a valve element connected to the motor fuel tank;
- (iii) a supply coupling device connected to the valve element the supply coupling device receiving the fuel from the motor fuel tank and the fuel from one or more supply fuel lines from the main fuel source;
- (iv) a pump fluidly connected to the supply coupling device for receiving the fuel from the supply coupling device and providing the fuel to an onboard motor, wherein the valve element stops fuel flow from the motor fuel tank when the main fuel source supplies the fuel to the supply coupling device and automatically allows the fuel flow from the motor fuel tank to the pump when a system failure prevents the main fuel source from supplying the fuel to the supply coupling device;
- (v) a return coupling device for receiving the fuel from the onboard motor and transferring a first portion of the fuel through one or more return fuel lines to the main fuel source while transferring a second portion of fuel to the motor fuel tank;
- and
- (vi) a plurality of fuel pressure regulators, each fuel pressure regulator of the plurality of fuel pressure regulators in communication between the one or more supply fuel lines and the supply coupling device for reducing fuel pressure coming from the one or more supply fuel lines.
