Upgrading the bottom of the barrel
In the past few decades, new technologies, including both carbon rejection methods and catalytic conversion methods, have emerged.
Composite ionic liquid alkylation technology gives high product yield and selectivity
Global sentiment has been moving toward a call to develop innovative technologies that address environmental preservation and limit the use of hazardous materials.
How the “LLF” condition monitoring technique can improve manufactured product profitability
Technological advances have allowed predictive maintenance (i.e., condition-based maintenance) to overtake preventive maintenance in plant operations. “Look, listen and feel (LLF)” is a condition monitoring technique that improves the reliability of equipment and machinery in manifolds.
Metallurgy solution to prevent polythionic acid stress corrosion cracking in hydroprocessing
Hydrotreating is a staple process found in nearly every refinery. The process removes undesirable feed contaminants, such as sulfur, nitrogen and metals, and saturates olefins and/or aromatics to produce high-quality products.
Reliability: Include pump wear rings in your upgrade efforts
Most centrifugal pump designs include replaceable rotating wear rings on the impeller (impeller wear rings) and stationary wear rings inside the casing (case wear rings). Although pump wear rings are simple components, they can have profound impacts on pump reliability, efficiency and safety. These wear rings serve three purposes:
Editorial Comment: It’s all in the makeup of things
This issue of <i>Hydrocarbon Processing</i> features a topic that has been addressed in sections of the magazine for several decades, but has never been a focal point of the publication. That topic is materials manufacturing.
People
Amy Hebert has joined Haldor Topsoe A/S as Deputy CEO and Executive VP (EVP), Chemicals.
Global Project Data
<i>Hydrocarbon Processing’s</i> Construction Boxscore Database is tracking more than 1,700 projects around the world.
Industry Metrics
Record low temperatures in the eastern US strengthened the diesel market but extended the downward trend in refining margins.
Evaluate structural stiffness for piping stress analysis
Hydrocarbon plants use a system of pipes of various sizes, pressures and temperatures. Sometimes these pipes have pulsating flows that result in piping system vibration. These piping systems must be designed for a high degree of reliability, which requires a comprehensive piping stress analysis for thermal, sustained, occasional and dynamic loading conditions.
