Abstract

A continuous blending system can be used to prepare burner fuel or blasting agent, and includes a mixer, a first hydrocarbon system, a second hydrocarbon mixer, and a computing system. The mixer is configured for continuously mixing a continuous supply of a first hydrocarbon and a continuous supply of second hydrocarbon to provide a mixed hydrocarbon at a flow rate and a predefined ratio of first and second hydrocarbon. The first hydrocarbon system provides a continuous flow of first hydrocarbon into the mixer. The second hydrocarbon system provides a continuous flow of second hydrocarbon system into the mixer. The computing system is in communication with and configured for simultaneously controlling the first and second hydrocarbon systems in order to obtain the mixed hydrocarbon at the predefined flow rate and at the predefined ratio of first and second hydrocarbon.
