LNG Properties

LNG Properties

Where can I find the properties of LNG such as viscosity, density and vapour pressure?

RE: LNG Properties

  Wewll, as you know it's about 90-100% Methane, so it's density is 26.5 LBs/Ft3... and weight about 3.5 lbs/gallon.  the Boiling temp is -259F and molecular weight is 16.04  Energy content is about 83,000BTU/gal and LFL=5% and HFL=15%.  The Viscosity can vary, but burning(flame) velocity is about .98 ft/sec.

Hope this helps... I imagine there are alot of sites out there you could try SPE (Society of Petroleum Engineers) though.

RE: LNG Properties

I found that the Chempak database from AFT does the calculation for LNG and 700 other chemicals. It provides fifteen parameters.

Thanks for the responses.

White Paper - Addressing Tooling and Casting Requirements at the Design Stage
Several of the tooling and casting requirements of a part can be addressed at the design stage. If these requirements are not addressed at the design stage, lot of time is spent in design iteration when the design reaches the die caster. These design issues lead to increase in time and cost of production leading to delay in time to market and reduced profits for the organization. Download Now
White Paper - The Other Side of Design for Assembly
Assembly level constraints need to be satisfied before the design can move downstream. This white paper will go through the various assembly level issues, which need to be tackled by various organizations on a regular basis. Know more about DFMPro, a design for assembly software. Download Now
