What harm can excessive outlet temperature of the scrubber tower cause to the subsequent system?
It is necessary to determine what is causing the synthesizer’s temperature to rise too high. After ruling out false readings from the instruments, possible causes include water in the synthesizer or inadequate cleaning effects; this could result in a high heat load on subsequent processing units and have an impact on the catalysts! ! !
1. If it is due to a problem with the instrument, it can be resolved promptly; the impact is minimal; 2. If factors such as the load on the vaporization furnace cause the gas exiting the quench chamber to remain unsaturated, and for various reasons the gas still remains unsaturated even after passing through the scrubber tower, superheated steam is emitted, which can result in significant errors in the measurement of the steam-to-gas ratio in the subsequent system ; 3. It is necessary to consider what process is used in the subsequent system; if a shift process with a high gas-to-gas ratio (1.4-----1.6) is employed, it will cause fluctuations in the shift system or in the furnace temperature ; If a low steam-to-gas ratio shift process (0.3-----1.0) is used, the impact is minimal; by exercising strict control and paying attention to fluctuations in pressure and temperature, it is also possible to overcome this issue ; 4. If the high outlet temperature is caused by poor washing efficiency of the scrubber tower or an excessive load, liquid water is often carried along with the gas stream; this can lead to a sharp rise in the liquid level in the separator at the inlet of the shift system. In severe cases, the liquid level cannot be controlled, and liquid water may end up entering the shift reactor, resulting in accidents ; 5. In addition to these, there are some other factors as well; they are related to the processes and techniques used in the subsequent system, as well as to the reasons for abnormalities in the scrubber tower. Therefore, the person asking the question must determine these conditions first before we can provide an answer – otherwise it will be very difficult. Hehe!
