"KARBATE" Impervious Graphite Vital to Increasing HCI Production
New Data Sheets Give Product Specifications on "Columbia" Brand Activated Carbon
Major Plant Items: " K A R B A T E " Falling-Film Absorbers, Stripping Towers, Boilers, Coolers, Condensers, Pumps and Piping. Process improvements made possible by National Carbon's introduction of impervious graphite have established hydrochloric acid and anhydrous hy drogen chloride as major industrial chemicals. Today, " K a r b a t e " imper vious graphite equipment is used in all HCI production processes. Photograph at left shows typical plant equipment producing anhy drous hydrogen chloride from by product HCI. Flow sheet below e m phasizes the role of " K a r b a t e " imper vious graphite in this operation; the "National" Graphite Combustion C h a m b e r shown is frequently used to produce raw HCI gas by combustion of hydrogen a n d chlorine. T h e d u r a b l e c o n s t r u c t i o n of " K a r b a t e " shell and tube heat ex changers, towers a n d centrifugal p u m p s is important to the design and continued economy of all types of HCI processes. A wide range of items available from stock at moderate cost. F o r details on " K a r b a t e " equip ment in H C I production, request Catalog Section S-7460 N L .
Designed to facilitate selection of proper type and grade of "Columbia" Activated Carbon in gas purification, gas separation, air conditioning, and catalyst applications. Includes product description, typical applications, prop erties, screen analyses and pressure drop curves. Request supplement to Catalog Section S-6450.
Technical Information on "National" Carbon Brick Now Includes Corrosion Resistance Tables
Cover use of "National" Carbon Brick for lining tanks, reactors and similar process vessels containing corrosive liquids or gases. Photograph above shows "National" Carbon Brick linings and "Karbate" Plate Type Heat Ex changers in nitric-hydrofluoric acid stainless steel pickling tanks. Catalog Section S-6215
HCI Storage—Loading Facilities Use "Karbate" Centrifugal Pumps
"Karbate" Centrifugal Pumps load and unload commercial strengths of hydro chloric acid at tank farms. Pump ca pacities up to 1500 gallons per minute at heads up to 125 feet cover wide range of loading requirements. Catalog Section S-7250
