Business Trends

Aglave, R., Siemens PLM Software

It is never a good sign when a piece of equipment exhibits unsafe behaviors—such as large, unexpected vibrations, or cracks forming around instrument ports—particularly in the thermal reactor of a sulfur plant, where high-temperature gaseous streams chemically react as part of the process that produces elemental sulfur.

Andrew, Bob, Hydrocarbon Processing Staff

Gulf Energy Information and Hydrocarbon Processing are pleased to provide a preview of IRPC Europe 2018, which will be held June 5–7 in Milan.

Three topics for operational excellence related to a Cr-Mo hydrotreating reactor

Lee, S., Kim, E., Jeon, S., SK Energy

Many end users are trying to use feedstock with higher sulfur content for their refineries to increase profitability, but numerous unknown or plausible bottlenecks exist.

Ross Systems and Controls (SysCon) recently completed the qualification to self-certify its touchscreen purged panels as meeting the rigorous standards of Underwriters Laboratories’ UL-698A Code and the National Fire Protection Association’s NFPA-496 Code.

CFD simulation in chemical reaction engineering

Aglave, R., Eppinger, T., Siemens PLM Software

Reaction engineering is a branch of chemical engineering that deals with the design and optimization of chemical reactors.

Upgrading the bottom of the barrel

Elshout, R., Energy Systems Engineering; Bailey, J., Brown, L., Nick, P., Consultant

In the past few decades, new technologies, including both carbon rejection methods and catalytic conversion methods, have emerged.

Advancing export terminal technology: An optimized process for the refrigeration of cryogenic hydrocarbons

Ethane production in North America (NA) has expanded dramatically with the onset of shale production and associated hydraulic fracturing. Ethane concentrations in fractured shale gas are typically 10% or higher vs. a traditional range of 4%–7% in associated gas.

Maximizing energy efficiency in paraxylene production—Part 2

Colling, C., BP AMOCO

Due to reduced margins, higher energy costs and rising atmospheric carbon dioxide content, energy efficiency has never been more important in refining and petrochemicals. This is particularly true in the modern aromatics complex, which produces paraxylene (pX), benzene and other aromatics from naphtha.

Due to reduced margins, higher energy costs and rising atmospheric carbon dioxide (CO2) content, energy efficiency has never been more important in refining and petrochemicals.

Heavy crude oil processing design and reliability

Martin, G., Liu, Z., Wang, S., GTC Technology US, LLC

Revamping refineries to process heavier crude slates goes well beyond the requirements to meet equipment performance dictated by a shift in the quantity of lighter product yields to heavier products.
