HASTELLOY Alloy D Trade-Mark

INCREASE YIELD OF ALCOHOL PLANT PROBLEM: To control the flow of corrosive sulphuric acid in an alcohol-acid plant and to stop unscheduled shutdowns to repair corroded valves. T h e acid is in concentrations of 50 to 60 per cent and at temperatures up to 250 deg. F.

REMEDY: Valves of HASTELLOY alloy D installed.

RESULT: T h e entire unit now operates on a four-month inspection and repair schedule. There are no un­ scheduled down periods with accompanying loss in production. HASTELLOY alloy D is resistant to all concentra­ tions of sulphuric acid at temperatures u p to and including the boiling points. I n many instances, use of alloy D has increased yields in chemical processes by permitting higher acid concentrations and temperatures. For a copy of a booklet describing HASTELLOY alloy D get in touch with the nearest Haynes Stellite Company Office.
