Abstract: A system for refining crude oil to minimize emissions of toxic compounds in the atmosphere during refining. The crude oil is treated with viscosity-reductant additives, reducing viscosity by up to 50% and increasing API gravity by more than 2 points. The method of spray-cracking and vacuum-flashing of crude oil, the system separates light and heavy end chains within the reactor. The vapor is condensed into designer fuels using a multi-stage horizontal reverse condensate-condenser or closed-loop distillation tower. Process heater directs flue gases through high-salinity fluids, such as a brine-processing device to capture, sequester, or mineralize the CO2, CO, NOx, and other contaminants from the flue gases. This results in a significant reduction in emissions, a further reduction to near-zero emissions (>95-98%) is achieved by the combination of (1) the closed loop processes, tank blanketing and capturing, sequestering and mineralizing emitted flue gases from the heater combustion-exhaust.
