Secrets of successful HAZOP scribing
Hazard and Operability (HAZOP) studies are one of the most commonly used hazard identification methods in the high hazard process industries. Experienced HAZOP leaders are crucial to the success of the study, bringing together their technical knowledge and team facilitation skills to ensure a comprehensive and accurate study. But the quality of the study, especially the output, is also highly dependent on the quality of the reporting, which is the work of the HAZOP scribe.
The rise and rise of liquefied natural gas
Natural gas comprises methane, ethane, propane and heavier hydrocarbons, plus small quantities of nitrogen, helium, carbon dioxide, sulphur compounds and water. Liquefied Natural Gas, or LNG, is produced by cooling natural gas to -160°C, once impurities such as water and carbon dioxide have been removed, which would otherwise solidify.
Hydrogen future: safety assessment of hydrogen facilities
Hydrogen is increasingly being used as a transport fuel in Fuel Cell Electrical Vehicles (FCEVs) thanks to its environmentally friendly nature and increasing availability from water electrolysis or steam reforming.
A rough guide to hydrogen sulphide
Around one-third of the world's gas fields contain 'sour gas', contaminated by sulphur compounds including hydrogen sulphide, also known as H2S. This gas is one of the most deadly hazards in the industry, making the fields more difficult to develop.
