What is the reason for the high level of sodium bicarbonate in the devulcanization desulfurization solution?
Thread Content
In the modified desulfurization solution, the ratio of sodium bicarbonate to sodium carbonate reaches 12
Is the CO2 content in the gas high? What is the composition?
It is generally difficult to control a high sodium carbonate content in shift gas desulfurization, mainly due to the high level of carbon dioxide during the shift process. It is best to install a flash tank before the regeneration tank after desulfurization to release some carbon dioxide.
I agree with the opinion above. In our facility, we have two systems for removing impurities; one of them is equipped with a flash tank in front of the regeneration tank, while the other doesn’t have such a tank. As a result, the system that has a flash tank shows quite significant improvements in performance
Reply to 1# YAODI2007: What catalyst are you using? What is the temperature of the solution? What is the flash pressure?
What should be the appropriate ratio between sodium bicarbonate and sodium carbonate? We have a flash tower in place, but the level of sodium bicarbonate is still too high. Please advise, experts
Increase the flash pressure to an appropriate higher level. What is the pressure in your flash tank?
