Hydrogenation accident
Thread Content
The hydrogenation feed oil contains a high amount of water; what is the impact of water entering the reactor on the catalyst? And post-water-entry treatment solutions
The title doesn’t match the content; it depends on how much water is included If there’s surface water, it might get completely shattered. It affects the strength of the catalyst carrier; excessive moisture content can lead to a decrease in the catalyst’s surface area, as well as to the breakdown or pulverization of the catalyst carrier, resulting in an increase in system pressure drop and a loss of active components. When the moisture content is low, it has little effect on the active metal components of the catalyst; however, at higher levels, metal aggregation occurs in these active metal components, resulting in a decrease or even loss of their catalytic activity.
Consequence: Fluctuations in the operation of the heating furnace, and reduced catalyst strength. Treatment: Drain water from the crude oil tank and identify which line is carrying water ； Manual operation of the heating furnace
It causes fluctuations in system pressure, fluctuations in the pressure of the heating furnace, and fluctuations in the pressure of the reactor. In mild cases, this causes pressure fluctuations and reduces the strength of the catalyst; in severe cases, the catalyst is completely destroyed, and even high-pressure heat exchangers may leak due to these pressure fluctuations. If the reactor experiences excessive overpressure after this occurs, attention should be paid to pressure relief; meanwhile, enhance water removal from the raw material buffer tank
