Chemical Pumps Metallic and Nonmetallic 325 • 15% is pulp and paper. • The remaining is in aluminum, rayon, cellophane, petroleum, soaps, and foods. The elecrolytic plants produce chlorine and caustic soda using a range of 250 to 1000 GPM and about 20 to 30 pumps. They also have 15 to 20 peripheral transfer pumps for hydrochloric acid, diluted H 2 SO 4 , and sodium hypochlorite. These plants use pumps of titanium, nickel alloys, cast iron alloy 20, CD-4MCu, and nonmetallics such as vinyl ester. Sodium-Hypochlorite NaOCl is a byproduct of the chlorine and caustic process. It is found in the bleach plants of paper mills with a concentration of 12% to 20%, in commercial bleach such as household Chlorox, and OEMs for swimming pool chlorination. The electrolysis of sea water (brine) with a concentration of 1 % to 3% is used for bleach plants, pulp mills, bleach plants for textile mills, and municipal waste treatment to kill bacteria. These plants use large amounts of sea water for cooling to prevent pipes from fouling with algae. It is also used in the pretreatment of desalinization intake and the pretreatment of secondary recovery brine in oil production. Pumps are alloy 20, titanium, and nonmetallic. Hydrochloric Acid—HCI Also known as muriatic acid, it usually requires Hastelloy B or titanium pumps. The primary consumption is pickling of steel for use with oil well acidizing where acid increases the permeability of wells by dissolving part of the limestone and dolomite formations. High purity aluminum chloride produced by aluminum hydroxide and HCI is used in pharmaceutical and cosmetic usage. In food processing, HCI is used in the manufacture of sodium slutamate and gelatin for conversion of cornstarch to syrup or adjusting the pH value in breweries. Sulfuric Acid—H 2 SO 4 With a 97% concentration, cast iron pumps are used. Eighty percent or less concentration is either alloy 20 or vinyl ester nonmetallic pumps. It has a very high boiling point, therefore a minimum loss is incurred at elevated temperatures. It is an excellent drying agent in the manufacture of chlorine gas. It is used for making fertilizers and explosives.
326 Centrifugal Pumps: Design and Application Ferrous and Ferric Chloride This is a byproduct from acid pickling of iron and steel. It is used for etching reagent in copper clad printed circuit boards, for electronics, or as a chemical coagulant for water treatment on waste water. The pumps are either titanium or vinyl ester. Chlorinated Hydrocarbons Chlorinated hydrocarbons are used to produce PVC, chloroform, carbon tetrachloride, solvents, flame retardants, insecticides, adhesives, Pharmaceuticals, metal cleaning, and dry cleaning. The pumps are usually 316 or ductile iron. Ethylene and Propylene Glycol Ethylene glycol is permanent antifreeze. It is also used in alkaline resins for coating in brakes, shock absorbers, and latex paints. Propylene glycol is used in the manufacture of unsaturated polyester resins. It is used to make cellophane, tobacco moisture retention material, brake flu* ids, and food additives. These pumps are either 316 or ductile iron. Synthetic Glycerine It is used for making resins, cosmetics, cellophane, tobacco, food beverages, and explosives. The pumps can be nonmetallic material. Corn Syrup Used in corn oil process. Usually 316 or nonmetallic materials. Dyes Used for such things as the ink in ball point pens and dying silk and wools. Usually nonmetallic pumps. Pesticides Insecticides such as malathion for controlling insects; herbicides for controlling plant growth. These materials are solvents and nonmetallic pumps are usually not suitable for this application.
