Regarding the issue of acid tar in saturators
Thread Content
Our factory has two saturated reactors in use for producing sulfur amine. In one of them, the acid tar floating on the surface of the flow tank exists in granular form, while in the other reactor it is in a diluted form. The first saturated reactor tends to get clogged quite easily, which results in high resistance in that reactor. What could be the reasons for this? Are there any ways to address it? For reference: the fan is equipped with an electric precipitator, and the voltage applied is 5 volts
Are the two sets of saturators operating in parallel? It’s still a separate system. It is possible that the gas composition of the two systems differs, as do their operating procedures; the acidity control in the two saturators may vary, or the sulfuric acid used might be different. Is regenerated acid being used? The acid tar floating on the full-flow channel is in granular form; its acidity may be high. Excessive acidity can lead to the formation of salts such as ammonium bisulfate due to an overload of acid. Because of their small size, these particles are difficult to extract, and they can cause deposits in the saturator, thereby increasing resistance ； The other type is dilute tar, with a potentially lower acidity. Due to the lack of clarity regarding the specific operational procedures, it is difficult to identify specific improvement measures. The meaning of the secondary voltage value for the electrostatic tar catcher is not clear; is it 50,000 volts? I wonder what the tar content level is in the gas after the blower?
Are the two sets of saturators operating in parallel? It’s still a separate system. Temperature and acidity control are different. Also consider whether ammonia is entering the device, and whether there is high resistance in the preheater.
