Major oil company proves corrosion resistance of ALCOA ALUMINUM Heat Exchanger Tubes ACID GAS REMOVAL PROCESS
Flow chart shows typical acte! gas removal w i t h uses of a l u m i n u m indicated. ALCOA A l u m i n u m alloys provide outstanding resistance to HgS and COg, contaminants commonly encountered ir» the petroleum industry. Both aqueous amine a n d glycol-amine solution systems employ aluminum in heat exchanger tubes, tower internals, etc. . . . for improved service life over alternate materials . . , at far lower cost. iPhotograph a t right shows lean MEA solution cooler referred to below.)
Over 750 days' exposure to corrosive gas contaminants has proved to a major oil company the superior resistance of ALCOA Alclad Heat Exchanger Tubes. Used in the lean M E A solution cooler of a Girbotol Gas Treater, the tubes are exposed to a solution carrying 10 grains of hydrogen sulfide per gallon at the rate of 350 gallons per minute. After more than two years of service, the aluminum tubes are virtually unaffected. Such service records have proved time and again that ALCOA Alclad Aluminum Tubes withstand corrosion best. Materials like hydrogen sulfide and carbon dioxide—normally corrosive to most metals—are not corrosive to aluminum. That means longer service life, less maintenance— to reduce process operating costs. What's more, ALCOA Aluminum Heat Exchanger Tubes in the common sizes cost far less than seamless tubes of other common materials . . . one-half as much as Admiralty brass . . . one-third to o n e - f i f t h as m u c h as cupronickel or stainless steel. It will pay you to use the handy c o u p o n today for complete details.
