The Steam Tools app is an iPhone application developed by Spirax Sarco to assist engineers have quick and easy access to both Steam Tables and a Saturated Steam Pipe Sizing tool.

Steam Tables
The Steam Tables cover the thermodynamic data for water/steam, supporting the design and operation of expert steam/water equipment. You simply need to enter a pressure or a temperature into the app, returning:

- The corresponding pressure or temperature.
- Water (hf) (Sensible Heat)
- Evaporation (hfg) (Latent Heat)
- Steam (hg) (Total Heat)
- Specific Volume Steam

Pipe Sizing Tool
The pipe sizing tool allows access to Saturated Steam pipeline data, helping you to size a pipeline.

You may easily download from Iphone's APP STORE. Read more information in ITune.

LNG Industry is an unique quarterly magazine that covers the global LNG sector from start to finish, from liquefaction to regasification. Each issue provides :
  • in-depth technical articles focusing on all aspects of the LNG sector
  • quality keynote articles from LNG majors, financial institutions and industry commentators
  • regular regional reports from Europe, North and South America, Africa, Asia and the Middle East
The Winter 2011 issue of LNG Industry has a particular focus on LNG safety and alternative uses of LNG apart from transportation, ranging from locomotive use to shipping fuel.

Winter 2011 issue covers following topics :

Picking up the pace
Terry Willis, The EIC, Dubai, examines the increasing pace of new LNG liquefaction capacity and exports from the Middle East.

Is anyone thinking about the weather?
Mark W. Jessup, Markey Machinery Co., USA, examines the world’s changing weather patterns and what LNG companies can do to prepare themselves for the worst.

LNG: the flexible element
James Patrick O’Brien, EGL AG, Switzerland, comments on LNG market developments and the future of LNG from a market participant’s perspective.

Is LNG on track?
Constantyn Gieskes, Braemar Wavespec USA, Inc., USA, describes the potential benefits and pitfalls of converting rail locomotives to run on LNG.

Gas fuel: a new generation
Reidar Strande, Hamworthy Plc., UK, discusses the benefits of an LNG fuelling system.

The missing link
Jürgen Harperscheidt, TGE Marine Gas Engineering, Germany, discusses the development of bunkering LNG for shipping uses.

Who’s in control?
Dr. Ian Synge, ShipNet AS, UK, discusses the growing use of enterprise software to transport LNG efficiently and safely.

Intelligent valves
Sari Aronen, Metso Automation Inc., Finland, explains the benefits of selecting the right valves for LNG processing applications.

Pressure relief
Roger Bours, Fike Europe, Belgium, addresses the use of pressure safety devices in cryogenic processes.

Time to switch?
Amin Almasi, WorleyParsons, Australia, examines the benefits of switching to new aero-derivative gas turbines over their heavy frame counterparts.

Sustainable insulation
Steve Oslica, Pittsburgh Corning, USA, examines the environmental credentials of cellular glass insulation.

Mercury removal
Vince Atma Row and Matthew Humphrys, Johnson Matthey, UK, examine the problem of mercury adsorption on gas plants and pipelines.

Natural gas is used in industry and household to provide heating energy. It is explored from gas well, treated transported to customer via large and long pipeline. It is become non-cost effective once the pipeline length is exceeded 3000 - 3500 km. Thus, another mode of transportation, Liquefied Natural Gas (LNG) is considered cost effective. Liquefied Natural gas (LNG) is a process of cooling down the natural gas to form liquid for easy storage and transportation.  A LNG is normally contains of Methane (CH4) which is more than 90% and other light hydrocarbon such as Ethane (C2H6), Propane (C3H8), Butane (C4H10) and Nitrogen (N2) inert gas. LNG is non-corrosive, non-toxic, non-carcinogenic, odorless and colorless. However, it is flammable and explosive and create greenhouse effect to environment.
 Following is an simple development milestones for LNG since 19th century

Year Event Remark
19th Century
Michael Faraday, a British Scientist liquefying various gases (including natural gas) in laboratory

1873 Karl Von Linde, a German engineer build 1st practical compressor refrigeration machine in Munich
1912 1st LNG plant is built in West Virginia
1914 1st (U.S.) patent awarded for LNG handling/shipping to Godfrey Cabot
1917 Start operation of 1st LNG plant in West Virginia
1941 1st commercial LNG plant is built in Cleveland, Ohio 2000 tpa
1944 At an LNG peak-shaving plant in Cleveland, an LNG storage tank with a low Nickel steel content (only 3.5%) fails. LNG spills into a sewer. Explosion within the sewer kills 128 people
1959 World 1st LNG tanker "The Methane Pioneer", safely carries LNG from Lake Charles, LA., to Canvey Island, United Kingdom, initiating commercial LNG shipping. 2000 tonnes LNG
1960 Conch International Methane conducts pioneering series of experiments involving small-scale LNG spills on land at Lake Charles, LA for U.S. Bureau of Mines.
1964 1st baseload LNG plant (CAMEL) in Algeria used Technip/Air Liquide's Cascade liquefaction process  (three loops i.e. Propane, Ethylene & Methane) and Steam turbine to drive compressors

The British Gas Council begins importing LNG from Algeria, making the United Kingdom the world's 1st LNG importer and Algeria as its first exporter.
3-trains with capacity of 1 mtpa, located in in Arzew, Algeria
1967 National Fire Protection Association (NFPA) adopts its first LNG safety standards, NFPA 59A Standard for the Production, Storage, and Handling of LNG.
