Chevron sees weaker US, global refining margins

During the first two months of the fourth quarter, US refinery crude-input volumes decreased by 77,000 bpd compared to the third quarter, driven primarily by the continued shutdown of the Richmond, California refinery crude unit. International refinery crude-input volumes increased 9,000 bpd.

Fluor, JGC win design work for Mozambique LNG

The FEED work will deliver designs for the initial phase of the Mozambique LNG project of four trains, each train capable of producing 5 million tpy of liquefied natural gas (20 million tpy total). The project has the potential to expand its capacity up to approximately 50 million tpy of LNG in the future.

Eni reports Gela refinery working normally again after port suspension

Port authorities Friday authorised a new tugboat to start work in Gela after a suspension had meant that ships couldn't service the refinery for days, which would have eventually resulted in a stoppage at the plant. The Gela refinery has a daily production of about 100,000 bbl of oil.

CB&I, Chiyoda win engineering, design work for Mozambique LNG trains

The FEED will deliver designs for the initial phase of the Mozambique LNG project of four trains each with 5 million tpy of LNG production capacity. This project is the first LNG project in Mozambique, and it has the potential to expand its capacity up to approximately 50 million tpy of LNG in the future.

Optimize LNG boil-off gas systems for regasification terminals

Ranhill WorleyParsons: Zolfkhani, M.

Depending on LNG composition, N2 content and plant operating mode, an operating pressure of 7 barg to 8 barg was found by the study to be the optimum pressure range.

Molecular sieves in gas processing: Effects and consequences by contaminants

CECA SA: Terrigeol, A.

The principles of adsorption on molecular sieves are easy to understand, but practice sometimes reveals traps to avoid.

Improve evaluation of brittle-fracture resistance for vessels

Becht Engineering Co. Inc.: Sims, J. R.

This article discusses a new approach and spreadsheet tool for engineers that can be used to provide operating pressure limits as a function of vessel-metal temperatures.

Evaluate pressure relief system forces in existing installations

Smith & Burgess LLC: D. Smith  |  White, J.
Frenk Water Technologies LLC: Frenk, B.

The purpose of this study is to limit the number of relief valves that require rigorous engineering calculations to determine the adequacy of the installation.

Improve your plantwide steam network

Merrick & Co.: Pelham, R. O.

When optimizing an existing steam network, design and process engineers need a complete understanding of all aspects of the existing system. Accurate energy and material balances must be established.

Update on wet and gas compressor seals

Hydrocarbon Processing Staff: Bloch, Heinz P.

Shaft seals keep compressed gas from leaking out. The need for leak prevention may include process economy, safety and environmental protection. Moreover, the process gas will usually have to be kept ..
