Industry Perspectives: Hydrocarbon Processing’s IRPC returns to Europe in June

Lee Nichols, Hydrocarbon Processing

Founded in 2009, Gulf Publishing Company and Hydrocarbon Processing’s International Refining and Petrochemical Conference (IRPC) provides a series of events for the international downstream industry covering technical innovations, and exploring both the challenges and opportunities found in today’s market.

Continuous corrosion monitoring of crude overhead systems

Davies, J., Permasense

The growing availability of light tight oils (LTOs) is resulting in a choice for refiners between upgrading metallurgy or chemical inhibition and corrosion monitoring to manage the increased corrosion risk. With tight budgetary constraints in place, many oil companies are opting for chemical inhibition and online corrosion monitoring.

Hybrid technique for electroslag strip cladding of critical process equipment

Chattopadhyay, P., Nateghi, A., Lincoln Electric

One of the major challenges in the oil and gas processing industry is to strike a balance among handling the changing qualities of petroleum products and byproducts, increasing the productivity and service life of critical components and reducing environmental hazards. As an example, new refineries are moving to applying conversion methods, such as hydrocracking, to increase yields, while also utilizing conventional distillation. This juxtaposition translates into a higher Nelson Index rating. Greater refinery complexity makes processing low-quality crude oil difficult, if not impossible, thereby precluding bottom-of-the-barrel products.

Improve understanding of corrosion inhibitor technology for processing high-acid crudes

Ondyak, J., Noland, J., Shah, P., Subramaniyam, M., Dorf Ketal Chemicals

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

Adrienne Blume, Hydrocarbon Processing

Gulf Publishing Company and Hydrocarbon Processing are pleased to announce that IRPC 2017 will be held April 18–20 in New Delhi.

Editorial Comment: Corrosion prevention starts at fabrication

Andrew, Bob, Hydrocarbon Processing Staff

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.

Build a diesel fuel performance additive, the right way—Part 1

Pipenger, G. G., Amalgamated, Inc.

Many diesel fuel additive companies in North America supply different additive products formulated for diesel-powered equipment.
