https://en.wikipedia.org/wiki/Ammonium_chloride

Ammonium chloride is an inorganic compound with the formula NH4Cl and a white crystalline salt that is highly soluble in water. Solutions of ammonium chloride are mildly acidic. In its naturally occurring mineralogic form, it is known as sal ammoniac. The mineral is commonly formed on burning coal

Ammonium chloride is a white crystalline solid. It is soluble in water (37%). The primary hazard is the threat posed to the environment. Immediate steps should be taken to limit its spread to the environment. It is used to make other ammonium compounds, as a soldering flux, as a fertilizer, and for many other uses.

Ammonium chloride formation is a function of localised conditions: temperature, concentration of HCl, and concentration of NH3: NH3 (gas) + HCl (gas) → NH4Cl (solid) As the partial pressures of NH3 and HCl increase and the temperature decreases, the potential for ammonium chloride fouling increases. Under-deposit pitting corrosion is predominantly caused by …

In all cases, ACF displaces the weaker base ammonia by forming a liquid salt. In the absence of free water, the salts are transported at temperatures below 180°C together with the hydrocarbon stream. When they come into contact with water, the …

Mar 11, 2001 · Ammonium chloride salt deposition is a problem in many units when sufficient amounts of both ammonia and hydrogen chloride are present. Solid ammonium chloride can deposit and collect on metal surfaces and impede the flow of gases, liquids, and heat. Ammonium chloride can deposit in towers, on distillation trays, in transfer lines, on heat ...
