Process for using anti-coking steels for diminishing coking in a petrochemical process

摘要

For diminishing coking in a petrochemical process, coking-resistant steel containing by weight: about 0.05% to 0.06% of carbon; about 2.5% to 5% of silicon; 10% to 20% of chromium; 10% to 15% of nickel 0.5% to 1.5% of manganese; 0-0.5% of titanium; at most 0.8% of aluminium; the complement to 100% being essentially iron, can be used to manufacture tubes and plates for producing reactors or elements thereof, as well as for coatings of the internal walls of furnaces, reactors or tubings where coking can occur.
