Carburization inspection robots for radiant tubes inside ethylene cracking furnaces
In an olefins plant, the reliability of ethylene cracking furnaces is one of the deciding factors used to indicate whether or not the plant can be operated at its design productivity.
Does your control valve talk?
Pneumatic operated control valves (POCVs) are consistently the most used control final element for process control across most industries—in some cases, they are also part of the safety instrumented systems (SISs) layer.
Revamp fired heaters with a common air-preheating system to increase capacity
In any process plant, fired heaters are generally considered to be one of the most optimally designed pieces of equipment.
Enhanced flash zone design for coker fractionators
Since the flash zone is the first process undergone by the coke drum effluent vapor upon entering the column, the operation of the flash zone is critical to the operation of the entire coker fractionator column.
Industry Perspectives: Hydrocarbon Processing’s IRPC returns to Europe in June
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
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
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
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
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
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.
