The sulfur recovery unit (SRU) separates sulfur from sulfur compounds.

Develop more efficient capital projects with an EPC 4.0 strategy

Sabharwal, A., Aveva

Digital technologies are being widely adopted across nearly every industry. Industrial companies are moving as far away as possible from manual, document-centric processes and replacing them with cloud services, digital solutions and data-centric strategies.

Engineering propylene: Value unlocking with the PDH process

Qureshi, V., Singh, R., Chate, V., Bechtel India

Propylene is at the core of the petrochemical industry, with the synthesis of its numerous derivatives finding greater application in industries from textile to automobile, cosmetics and beyond. Propylene is also a foundation block/intermediate for numerous chemicals, from isopropanol to polypropylene (a widely used synthetic material) to gasoline octane enhancers.

Crude oil has been the fundamental element of transportation fuel for many decades.

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.

Effectively clean air fan coolers with water and steam

In many refineries and petrochemical plants, air fan coolers (AFCs) become a major bottleneck to increasing plant capacity. Many plants suffer from lower heat duty than designed, especially during the summer months, which can lead to lower plant capacity.

Leveraging modern flow technologies to improve safety in refineries

The refining industry is facing increased pressures, such as crude oil supply changes, changing product distributions and increasing regulations. These pressure points create a highly competitive market where refiners are looking for options that include digitally transforming operations and adapting new technologies to enhance safety and improve uptime, flexibility and efficiency, while securing their competitive position in a dynamic market. Improving personnel and process safety remains a top focus area for refiners.
