Base layer enhancement study for crude oil distillation process

Şanli, H. Ç., Er, B., Tüpraş

Base layer control is one of the most important stages of a process control system hierarchy for refinery applications.

Steam generator in a hydrocracker high-pressure loop—why not?

Historically, there has been a perception in the industry that it is not safe to include a steam generator in the high-pressure loop of a hydrocracker.

Inspection: Establish an inspection plan for flare burners

Anwer, A., Ruwais

Flares are prominent in hydrocarbon processing operations. From afar, they can be spotted burning with a high or low flame, supported by a tall steel structure

Use CFD modeling to improve burner design and operation

Chen, Z., Becht

Process heaters are essential pieces of equipment in the refining and petrochemical industry that are used to heat hydrocarbons to a desired temperature.

Alternatives to ladders and platforms for inspection and maintenance of elevated flare tips

Rastogi, A., Fluor Daniel India

Flare systems are used in refineries and chemical plants as a last line of defense for the plant by burning all unwanted gases and liquid during any upset or emergency condition.

Cost-effective naphtha hydrotreating unit revamp to increase high-octane reformate production

Ramesh, K., Phukan, D., Indian Oil Corp. Ltd.

India, which is the third-largest economy in the world, is home to nearly 18% of the world’s population (nearly 1.4 B).

Apply ceramic coatings to extend radiant tube life in process heaters

Bacon, J., IGS-Cetek

Process tubes in refining applications are typically steel alloy (ASTM A335 P22, P5 or P9), which contain 2.25%, 5% and 9% Cr, respectively. These grades oxidize at operating temperatures, and scale will grow continuously on the surface, often reaching 2 mm in thickness in higher-temperature/high-heat-flux units. The layers of scale are very insulating and represent a significant barrier to conductive heat transfer to the process.

Case study: Heat exchanger tube rupture and its impact on metal embrittlement

Dingankar, S., Mahulkar, S., Reliance Industries Ltd.; Schutt, M., Mahalingam, S., TechnipFMC; Banerjee, S., Technip India Ltd.

Process engineers strive to recover as much energy as is practically possible from the available process and utility streams within the constraint of the plant. To achieve this goal, traditional—and sometimes non-traditional—methods are utilized. In a steam cracker, light olefins are considered the highest-value products, and utilizing “cold energy,”

Heat Transfer: Designing electric process heater systems for catalytic regeneration

Bartell, P., Valin Corp.

Achieving effective catalyst regeneration requires a process that produces a very high level of heat in a very efficient manner. Over the years, several different approaches have been taken to create this required heat. Traditional steam has been a popular choice, as has heated transfer media. However, these methods have limitations.

Reliability: When slow-rolling machines can cause failures, and how to avoid them

Bloch, Heinz P., Hydrocarbon Processing Staff

All the book learning in the world will fail if we do not use common sense. We could also say that we need to think things through and should recognize that intuitive logic can lead us astray. If that sounds like semantic banter, let us zero in on three practical field examples that illustrate the issues at hand.
