Service Life Prediction of 9% Ni Steel LNG Storage Tank Using Fatigue Analysis

Apr 5, 2012
Seung-Rim Lee
As the design life expiration date(about 25 years) approaches for domestic LNG storage tank, the issue of tank lifetime extension is paid more and more attention by the Korea LNG industry. Recently, Korea Gas Safety Corporation is carrying out a project for developing technologies and standards for...

Furnace Stories

Apr 5, 2012
Ken Beasley
The cracking furnace is the heart of the ethylene plant, consuming the most energy, adding the most value and with the potential to cause the most damage. Every aspect of the furnace is critical from the specifications through design, construction and including commissioning, start-up, operations,...

Galvanic Corrosion Between Dissimilar Metals

Apr 5, 2012
Richard Rolke
A Dow USGC cracker suffered a tube failure on a cracked gas compressor inner stage cooler after ten plus years of service. To further extend the equipment life, the decision was made to replace the tube bundle and upgrade the metallurgy of the tubes from admiralty brass to Duplex stainless steel...

Tutorial on Hydroprocessing: ìHydroprocessing Catalysts and Processesî

Apr 4, 2012
Paul Robinson
The products of petroleum refining must meet tight specifications, including limits on sulfur, nitrogen, olefins, aromatics, and other contaminants. Hydrotreating removes these contaminants from distilled crude oil fractions and intermediate process streams. Hydrocracking converts heavy oil...

Delmar R. Morrison
Liquefied Natural Gas (LNG) has been a growing energy resource in the U.S., for which significant import and storage infrastructure was developed in the past decade. The infrastructure for liquefaction and export has also been developing as a result of recent shale gas finds in North America. In...

Design Considerations for Diesel Hydrotreaters

Apr 4, 2012
Ian M. Glasgow
In 2006, the United States EPA mandated the use of 15 ppmw ultra-low sulfur diesel (ULSD) for on-road diesel fuel. At that time several refiners either revamped existing facilities or constructed grass roots facilities to meet the specification. Some facilities did not implement ULSD process...

Turnaround Excellence - Key Success Factors

Apr 4, 2012
Bobby Vichich
Turnaround Excellence is more than a state of being… it is a journey. Achieving and sustaining excellence is wholly dependent on a site approach of shared accountability towards Turnaround Excellence and must be a continually improving process. Starting well in advance of “feed out”, a long range...

Troy Schuenemann
Optimizing the clearing and cleaning of process units during turnarounds. Primary discussion involves the three key areas related to an effective, timely cleaning plan. Chemistry, planning and execution. Minimization of effluent is also addressed. Overall timeliness, from oil out to vessel entry,...

Dynamic Simulation: Value During LNG Process Design and Beyond

Apr 4, 2012
Kenneth V. Allsford
A contributor to complex/large project management difficulty is uncertainty gaps – gaps between the information required and that readily available within the project organization. Moreover, for large projects, information is generally spread among many professional personnel across multiple...
