The refiner s position on inorganic solids and salt removal is that as much of these contaminants (as is cost-effective) should be removed from the incoming crude oil into the wash water by the desalting process. Excess chloride salts become catalyst poisons that promote excessive catalyst consumption or reduce conversion in the cracking and treating processes. Chloride salts also compromise the reliability of refinery overheads where, because of hydrolysis upon heating, they form highly corrosive hydrochloric acid in the overhead system. (The refinery overhead is the equipment, such... 

Hydroxyalkylations are catalyzed by Lewis-type acids, like AICI3, and by mineral Bronsted acids. Some papers and patents have appeared in recent years, where zeolitic materials are described as catalysts for this reaction [1-4,7]. Solid acid materials are highly desirable catalysts, since the environmental impact of the process benefits fi-om easier separation of the catalyst, the absence of liquid wastes containing inorganic salts, and less severe corrosion problems. 

Contact with water. This is commonly the case with the corrosive solids, such as the inorganic base potassium hydroxide and the organic crotonic acid. As solids, these do not have any available hydrogen or hydroxyl ions but easily form solutions in contact with water or moisture fi om the air or from skin, eyes, lung tissues, etc. 

ALUM (10043-01-3) Al2(SOj3 Noncombustible solid. Forms sulfuric acid with water. Aqueous solution has a violent reaction with bases, amines, amides, inorganic hydroxides, and many other materials. See also sulfuric acid. Dry material is weakly corrosive to carbon steel aqueous solution attacks aluminum and other metals, forming hydrogen gas. Hydrogen gas can accumulate to explosive concentrations within enclosed or confined spaces.
