文摘
The study simulated the sulfidation reaction of Fe2O3 and H2S in oil tanks containing sulfur under aerobic condition. To evaluate the pyrophoric tendency of H2S corrosion product, the oxidation reaction was taken under different temperatures after the sulfidation reaction and the temperature changes were measured during the oxidation process. The results showed that, with the increase of initial O2 concentration in the mixture of sulfidation gas, the oxidation possibility of the sulfidation product in the sulfidation process increased, then the final amount of sulfidation product in the oxidation process decreased, and the pyrophoric reactivity of H2S corrosion product decreased. The higher the initial temperature at which the oxidation of the sulfidation product took place, the faster the temperature of the oxidation reaction rose, and the greater the pyrophoric reactivity of H2S corrosion product.
