A fuel-gas blending system receives low-pressure tank vapors and high-pressure flash gases from an oil production facility, boosts the pressure of the tank vapors, and blends the tank vapors and high-pressure gases together to supply fuel gas at a pressure and quality required by an onsite fuel-gas-powered generator. The quality of the supplied fuel gas is maintained by controlling the proportion of a high-pressure gas, such as separator gas, in the blend while the volumetric flow rates of the various gases vary in response to the real-time demands of the generator. The system operates in one of multiple modes in order to maximize the use of tank vapors. In one mode, all the gases pass through a low-pressure blower. In another mode, only the tank vapors pass through the blower, and the high-pressure gases are blended with tank vapors downstream of the blower.

A control system for controlling operation of a fluid delivery system that includes a first and second pumps for delivering first and second fluids for mixing. A controller includes a first pump map having a first pump flow rate mapped against a control output signal, and a second pump map having a second pump flow rate mapped against a control output signal. The controller determines the control output signal for the first pump to obtain a desired flow rate from the first pump, and the control output signal for the second pump to obtain a target flow rate and a target percentage of the second fluid relative to the first fluid or a target percentage of the second fluid relative to an overall fluid flow. The output signals for the first and second pumps are determined using the first and second pump maps.
