EnduraAlon™(Alonizing™) Diffusion Coating Protects Tubes In Sour Gas Plant Waste-heat Boilers
Situation:
The Shell Caroline gas plant, one of the largest sour natural gas processing facilities in the world, is designed to process 8533 x 103 m3/d of raw gas and gas equivalent of liquid hydrocarbons. The overall sulphur recovery for the facility is 99.8% of the total sulphur intake, and sulphur production is approximately 4000 tonne/day. This facility began operating in late 1992.

EnduraAlon™(Alonizing™) Diffusion-coated So2 / So3 Heat Exchanger Tubes Operating Efficiently Since 1966
Situation:
In 1966, Fenco Engineering Company built a sulfuric acid plant for SO2 abatement purposes using Alonized™ tubes for a non-ferrous mining company with a smelter operation in Ontario. In 1988(22 years later) this customer asked Fenco to conduct a study to see if the plant could last another five years, after which time it would be replaced with a more modern, larger facility which would handle all of the off-gas streams in the property.

Acid Gas Removal Improved Claus Sulphur Recovery
Situation:
Recently, 26,000 ASTM A192 carbon steel heat exchanger tubes were Alonized™ diffusion-coated for ADNOC, Abu Dhabi National Oil Company, to provide scaling and corrosion resistance to acid gases. These gases, generated during the treatment of natural gas or hydrocarbon streams, start out in the form of hot exhaust gases. They then are desulfurized by a Claus process to yield either sulfuric acid or elemental sulfur, thereby converting and recovering 94 – 99% of the sulfur compounds and, in some cases, as much as 99.9% of these compounds.
