Abstract

Westaim has undertaken a major R&D initiative with the goal of bringing a low coking environment to the ethylene industry through the use of surface alloyed tubes and fittings. Coating materials have been identified capable of greatly reducing catalytic (filamentous) coke formation in laboratory and pilot plant pyrolysis testing. Process technologies have been developed for the application and surface alloying of these materials to the internal surfaces of a wide range of commercial tube and fitting geometries and base alloy compositions. The resulting surface alloys have unique pre-engineered physical, mechanical and chemical properties to ensure viability in the severe operating environment of pyrolysis furnaces. These include: a regeneratable (self-healing) inert surface for resistance to catalytic coke formation; high resistance to carburization, hot erosion, hot corrosion and thermal shock; and, high ductility. This paper focuses on key laboratory and pilot plant results generated to-date, and a status update on commercial furnace trials and the commercial launch of the new coated products.
