Method for preventing fouling of a demister

A method for preventing fouling of a demister comprising:

• providing a vessel, the vessel comprising the demister in an upper portion of the vessel, a gas inlet in a lower portion of the vessel, and a diverter section in a first middle portion of the vessel;
• providing a process fluid into a second middle portion of the vessel;
• providing a gas to the gas inlet, wherein the gas comprises a component that desublimates, condenses, crystallizes, solidifies, reacts, or a combination thereof, in the process fluid, forming a first solid;
• passing the gas through the gas inlet into the process fluid, the component of the gas forming the first solid, resulting in a component-depleted gas, wherein the component-depleted gas passing out of the process fluid causes splashing or spurting of the process fluid and the first solid;
• and,
• providing the diverter section between the demister and the gas inlet, the diverter section comprising a physical obstruction preventing the process fluid and the first solid from splashing or spurting onto the demister;
• whereby fouling of the demister is prevented.
