Liquid sulfur pipelines are prone to blockage (due to the presence of impurities, the flow condition, and the slope); exhaust gases may exceed regulatory limits (related to the air ratio). Careful attention must be paid to the organization and inspection of the heat tracing and condensate systems.
The top of the quench tower is prone to clogging, and the foam breaker screen gets blocked
In liquid sulfur pipelines, blockages are likely to occur when the temperature is low
1. The main operation is to ensure proper and timely air distribution. 2. The blockage is mainly caused by the low temperature of the heat tracing for the liquid sulfur line ； The liquid sulfur outlet of the exhaust gas separation tank is prone to the accumulation of a mixture of rust, catalyst powder, and sulfur, which can cause blockages ； The quench tower can experience sulfur penetration due to delayed hydrogenation in the hydrogenation reactor, leading to blockages ； First-stage reactors may experience bed blockage due to inadequate aeration caused by excessive hydrocarbons
Operational challenge: Adjust the air-fuel ratio in a timely manner based on the volume of acidic gases. The most common blockages are the liquid sulfur outlet of the sulfur condensation cooler, and the inlet filter screen of the sulfur seal tank. If the air supply is not timely, the demisting mesh of the ultra-cold tower will become clogged; in severe cases, the ultra-cold water will turn milky in color and contain sulfur particles
