Shale and rock formations are being used to increase natural gas production in the […]
[ad_1] Gas production plants converted coal or oil into gas for lighting, heating, and cooking. They were common from the late 1800s to mid-1900s, but were replaced by natural gas. The plants relied on carbonization or gasification to create gas and produced useful by-products. Most sites have been dismantled due to toxins, but Gas Works […]
[ad_1] A gas valve regulates gas flow and is made of brass to avoid sparks. Gas fittings use a counter-clockwise thread to prevent unsafe valves from being installed. Bubble testing and Teflon tape ensure quality connections. Locking lugs and push-down valves are safety features to prevent accidents. A gas valve is a device used to […]
[ad_1] A gas contractor is licensed to work with gas lines and equipment, and must have a full license to install and repair gas equipment. Unlicensed workers may only work under supervision. Gas contractors install and repair gas appliances, generators, and gas lines, and must also dispose of gas appliances. Being licensed to work with […]
[ad_1] Gas regulators reduce gas pressure in containers and cylinders, ensuring gas quality and safety. Single-stage and two-stage regulators are common types, with other variations for specific applications. Proper installation and maintenance are crucial, and replacement is necessary every 15 to 25 years. Gas regulators are devices that are used to reduce the pressure of […]
[ad_1] A fuel dispenser pumps fuel into vehicles and containers. They can be found at public and private stations and come in different fuel types. They have safety features, and regulatory agencies inspect them for accuracy and safety. A fuel dispenser is equipment that pumps fuel for distribution into vehicle tanks and portable fuel containers. […]
[ad_1] Gas chromatography is a method used to analyze the chemical components of a gas sample by vaporizing it and separating the components in a column. It can determine the presence and concentration of specific compounds, but multiple tests may be needed. It is used for purity testing, compound identification, and forensic analysis, but requires […]
[ad_1] Acid gases, such as hydrogen sulphide and carbon dioxide, must be removed from natural gas through amine gas treatment to prevent pipeline damage and toxicity. Sweetening with ethanolamine is a common method. The term acid gas covers any type of gas or gaseous mixture which forms an acidic compound when mixed with water. The […]
[ad_1] A gas mass spectrometer detects the concentration of elements in known and unknown samples by sensing the deflection of charged ions in a magnetic field. Inorganic analysis produces a characteristic spectrum, while organic analysis is more complex. In a gas chromatography mass spectrometer, compounds are separated by gas chromatography before being sent to the […]
[ad_1] Inert gases are unreactive elements including helium, neon, argon, krypton, xenon, and radon. Inert gas welding uses an electric arc and an inert gas to protect the weld from oxidation. MIG welding uses a consumable electrode while TIG welding uses a non-consumable tungsten electrode. MIG welding is less expensive but messier, while TIG welding […]
[ad_1] Gas welding is a skilled craft used to cut and join metal, taught through specialized trade programs. There are three types of equipment, each using different gases, with TIG welding being the best option for aesthetics. The type of gas welder used depends on the thickness of materials. A gas welder uses compressed gas […]
[ad_1] Landfill gas is produced during the decomposition of organic materials in landfills. It is primarily methane and carbon dioxide and can be flammable and contribute to global warming. Modern landfills trap the gas and use it to generate electricity, power vehicles, create heat, or sell commercially. Landfill gas is the gas produced during the […]
[ad_1] Shale gas is natural gas extracted from shale wells using hydraulic fracturing and horizontal drilling techniques. Shale is rich in organic matter and minerals, but shale gas extraction has been controversial due to potential environmental harm. Recent technological advancements have made shale gas extraction more profitable and many countries are looking to it to […]
[ad_1] Gas is a state of matter with unique properties such as expansion to fill any space, ease of compression, and little resistance to objects passing through it. When transformed from a liquid or solid, the volume of the substance changes drastically. A gas is one of the four states of matter and has properties […]
[ad_1] Gas chromatographs are used to ensure the correct alcohol content in wine. The device analyzes organic compounds in the wine, identifying them using electronic equipment to determine the alcohol content. GCs are sensitive and relatively inexpensive, allowing even small wineries to use them. Manufacturers are constantly improving their products to optimize efficiency. To produce […]
[ad_1] Gas scrubbing is a process where a gas is removed from a mixture by contact with a liquid solvent. It is commonly used in packed towers or columns to remove impurities or recover gases. The solubility of the gas solute in the liquid solvent is the theory behind gas scrubbing. Temperature and pressure affect […]
[ad_1] A gas manometer measures gas pressure using a U-shaped tube filled with liquid, with one end connected to a pressurized gas container. Open-tube gauges use atmospheric pressure to measure gas pressure, while closed-tube gauges avoid this. Digital gauges are also available. A gas manometer is a device used to measure the pressure of a […]
[ad_1] The ideal gas is a theoretical state of matter with no interaction between molecules. The ideal gas law, PV = NkT, describes the relationship between pressure, volume, and temperature. The law is an approximation, but it is useful for understanding gas behavior. The Van der Waal equation corrects some assumptions but is not significantly […]
[ad_1] Gas mechanics work on gasoline-powered vehicles, performing maintenance, engine rebuilds, and adjustments. They must be knowledgeable in fuel injection, forced induction systems, and computer diagnostics. Gas mechanics must work on all makes of vehicles and attend periodic training to stay up to date with new technologies. A gas mechanic works exclusively with gasoline-powered vehicles, […]
