Improve understanding of corrosion inhibitor technology for processing high-acid crudes
For corrosion risk assessment and control, ample published research exists on the inherent corrosivity of combinations of naphthenic acid and sulfur in refining systems, but not on the chemistry and mechanism of corrosion inhibitors. This work offers refinery engineers insight into the construction of corrosion inhibitor molecules, as well as how differences in molecules impact the performance of the inhibitor and the risk of fouling in crude units and hydroprocessing units.
Driving innovation in the downstream: IRPC returns to New Delhi

Editorial Comment: Corrosion prevention starts at fabrication
Preventing corrosion begins with the choice of materials and methods used to fabricate the equipment, piping, valves and instruments that will be exposed to varying process conditions and weather. At present, designers and fabricators can select from a multitude of modern materials and methods. Once in service, effective asset integrity programs will use smart condition monitoring and, where needed, a treatment regime to sustain the useful working life of all components. In the Special Focus section of this issue, we provide several articles that illustrate good practices in vessel fabrication, corrosivity analysis and corrosion prevention treatment.
New method to measure TAN of crude oil and refinery distillation fractions
Many refiners look at discounted opportunity crudes as a way to improve their margin spread. The growing varieties of discounted opportunity crudes on the market contain certain risks for the purchaser, such as high naphthenic acid or sulfur content.
XOS launches sulfur, chlorine analyzer for petroleum refineries, labs
ALBANY, N.Y. -- XOS announced the release of Sindie +Cl, a sulfur and chlorine analyzer that delivers two critical measurements with one push of a button. It is the ideal for refineries and independent labs to certify sulfur levels in finished products and assess chlorine for corrosion mitigation.
