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...

Fuels Blending Technology and Management

In-Company Training
In today’s highly competitive marketplace, the economic and efficient management of blending operations and automation can give you that critical edge over competitors. Join refinery offsite automation expert Suresh S. Agrawal for an overview of the principles of operation and decision-making involved in the management, operation, control, optimization and scheduling of gasoline, diesel, fuel oil products and crude oil.

What Are We Going to Do with All This Natural Gas?” –

Mar 13, 2011
Sam Thomas
The success in Shale and other unconventional formations has dramatically expanded the N. American Natural Gas reserves and promises to also do so in many other parts of the world. New LNG liquefaction capacity in the Middle East and Asia along with additional large scale capacity from Australia...

Designing LNG Vapor Dispersion Exclusion Zones to Protect the Public

Apr 5, 2012
Jerry Havens
The LNG industry, if not the entire energy industry, may be at a crossroad. Expectation of large shale gas supplies in the United States, with a backdrop of international economies in precarious states, makes more uncertain the promise of major investments in LNG import facilities. Already, a...

Design Challenges in Tankage Modernization

Apr 4, 2012
James Kong
In order to comply with regulation requirements, a refinery needs to perform major revamps to produce different grades of Diesel, namely ULSD, Off-road Grade and Regular Diesel. The existing tankage allocation needs to be changed to accommodate the hydrotreater feed components and the new products...

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...

NOx Risk Mitigation for the Co-Feeding of Natural Gas to the Sasol CTL Complex

Apr 4, 2012
Michael Schnobel
Natural gas has been a co-feedstock to the reformers in the Sasol CTL complex since 2004. A more beneficial way is to re-route natural gas to the cryogenic separation unit and thus only reform the separated methane in the natural gas feed. However, introducing NO x into the cryogenic separation...

Evaluation of Dispersion Models for LNG Siting Applications

Apr 4, 2012
Andrew Kohout
The federal safety standards for LNG facilities under 49 CFR Part 193 approves the use of specific dispersion models for performing vapor-gas dispersion exclusion zones. In addition, provisions allow for the use of alternative models if approved by PHMSA. In 2010, PHMSA, in consultation with FERC,...

Future Fuels and Chemicals: Grand Challenges and Opportunities

Apr 2, 2012
Joseph Powell
To insure a Sustainable Future, CO 2 emissions must be reduced despite strong future growth in demand. “Easy oil” from conventional production will be less abundant, though coal and natural gas, as well as unconventional hydrocarbon reserves will remain in strong supply for decades to come. Carbon...

The Ubiquitous Hydrocyclone Separator: Theory and Practice

AIChE Webinar
Feb 10, 2009
Charles Petty

The hydrocyclone separator, which was invented in 1891 (see E. Bretney, “Water Purifier”, U.S. Patent 453,105) is widely used in process engineering as a classifier, a clarifier, or a thickener.
