Safety in the LNG Value Chain

Dec 12, 2012
Georges Melhem, Henry Ozog

In this webinar, presenters describe and examine potential LNG (liquefied natural gas) hazards and risk-reduction methods for the LNG value chain ― production and consumption.

The Effect of Turbulence on the Evaporation of LNG Spills on Water

Mar 24, 2010
An important element of the overall risk of near-shore and offshore LNG operations is the behavior of spills on water: how the spill first interacts with the water at the point of entry, how the liquid pool first forms and spreads and how the emanating vapors disperse. Several models exist for...

Designing for an LNG Loading Arm Failure

Mar 24, 2010
Dennis Taylor
Over the last few decades, LNG has vaulted onto the world stage as a viable candidate for future energy needs. Scores of studies have been done to illustrate the potential consequences of an accidental release of LNG. Some excellent studies have been reported, but uncertainties still exist because...

Fouling by Asphaltenes After and During Conversion

Mar 23, 2010
Irv Wiehe
During resid conversion processes, such as visbreaking or hydroconversion, more saturated pendant groups are cracked off asphaltenes, making them less soluble. Meanwhile, the more saturated volatile liquids formed during the conversion are often nonsolvents for asphaltenes. As a result, these...

Vapor-Liquid Equilibrium (VLE) Study of CO2 with MEA and Ammonia Solvents

Mar 23, 2010
Donald Johnson
In the carbon capture and sequestration (CCS )scenario, vapor liquid equilibrium (VLE) curves represent the theoretical relationship between local gaseous CO2 vapor pressure and the respective carbon loading in solution for a given operating temperature. It determines the maximum carbon content in...

CFD Simulation of Vapor Dispersion from LNG Jetting and Flashing Releases

Mar 23, 2010
Filippo Gavelli
The analysis of LNG hazards, particularly in the context of onshore facility siting, has historically focused on the consequences of atmospheric pressure releases, such as would occur in the event of a storage tank breach. Recently, however, the issue of flammable vapor clouds formed by high-...

Impact of MARPOL Annex VI Regulations for Marine Fuels Supply

Mar 23, 2010
Maoqi Feng
The International Maritime Organization's (IMO) has adopted new emissions standards, MARPOL Annex VI, for large ships and their fuels in order to reduce air pollution from the global shipping industry. For the Sulfur Emission Control Area (SECA), including North Sea and California, starting from 1...

Cooldown of Large Pipes During the Commissioning Phase of Cryogenic Facilities

Mar 23, 2010
Harri Kytomaa
Cryogenic facilities such as LNG receiving terminals operate at temperatures as low as -260F. During day to day operations, the temperature in the pipes of the facility is relatively uniform, leading to low material stresses in the pipes. However, during exceptional operations, such as the initial...
