The two explosion areas exist in the propylene oxidation to acrylic acid process asks the oxidation reaction to be kept away from the explosion area.The process of acrylic acid production was described,inclu-ding the operating area calculation and the determination of both operating area and deviation zone and the DCS realization there as well as the instrument accuracy’s influence on the operating area.
