Abstract: The application of near-infrared online automatic blending system (BRC, BPC) in gasoline blending at Hainan Refining & Chemical Company is briefly introduced focusing on analyzing some cases that blending deviation occurred by operating with BRC or BPC, and counter measures are proposed. Since these counter measures are realized, the deviations of gasoline blending reduce significantly, and the utilization of high octane blending components is more effective, resulting in a better economic benefit.

Key words: gasoline, near-infrared, online blending, BRC, BPC, blending deviation
