Furnace tube coatings reduce carbon formation andl increase efficiency in olefins plants

摘要

Coating technology that essentially eliminates carbon buildup on the interior of steam cracker tubes will be commercialized by Quantiam Technologies Inc. (Edmonton, Alta; www. quantiam.com). Commercial-scale tests in five ethylene crackers indicate that the coating can extend the time between furnace decokings to 1-2 yr for light feedstocks, whereas uncoated tubes have to be decoked about every 30 days, says Steve Petrone, chief executive officer.
