Abstract

Abstract A review is made of corrosion problems associated with butane isomerization units. In this connection, vapor-phase and liquid-phase butane isomerization are considered separately. Data reported include corrosion rates of nickel and Monel in HCl at 30 C, corrosion of Hastelloy alloys A and B in HCl at room temperature, effect of temperature on corrosion of nickel and Monel in 5 percent HCl, and corrosion of Type 1 Ni-Resist in unaerated HCl at room temperature. In butane isomerization units it is important that the feed be kept dry and that such impurities as sulfur, pentanes and olefins be reduced to a minimum. Adequate guard chamber capacity is a must. Alloys must be carefully selected for use in locations where corrosion is severe. 8.4.3
