Higher octane gas is usually not necessary for most vehicles and can increase fuel costs. The recommended octane for a car is listed in the owner’s manual or on the manufacturer’s website. Performance vehicles may require higher octane, but listening to the engine can also indicate if it’s needed. In some areas, higher octane gas […]
Tight gas is difficult to access due to the dense rock and sand surrounding the reservoir. Companies require a large financial incentive to extract it, but as energy prices rise, interest increases. Tight gas is found in coal deposits and requires finding a “sweet spot” to extract. Most deposits are at least 251 million years […]
Shielding gas is used in MIG and TIG welding to protect the weld from contamination. The gas mixture required depends on the type of welding being performed. Keeping the welding gun close to the work piece and following the manufacturer’s recommendations for gas flow is important. Cleaning the welding gun nozzle is necessary to remove […]
Gas plumbers specialize in installing and repairing gas plumbing and fittings for fuel and heat, such as propane and natural gas. They must complete an apprenticeship and demonstrate proficiency skills in an exam before practicing independently. Gas plumbers work for municipalities, gas companies, or as independent contractors. They must have a demanding and precise personality […]
Sour gas contains hydrogen sulfide in concentrations greater than four parts per million and must be treated before use. Acid gas is a natural gas with high concentrations of acid gases. Both require processing before use, and care must be taken during transportation due to hydrogen sulfide’s corrosiveness. Refineries can conduct tests to determine the […]
White gas, also known as naphtha, is a petroleum ether used as a feedstock for high-octane gasoline. It’s found in many household and industrial products, but overexposure can lead to health problems, including cancer. Companies have strict guidelines for its use, and it’s generally safe in small quantities. More properly known as naphtha, white gas […]
Gas compressors increase gas pressure and temperature for various applications, including natural gas transportation, refrigeration, and air brakes. There are seven common designs, including centrifugal, axial flow, and diaphragm compressors, each suited for different environments. Reciprocating compressors are being replaced by smaller, quieter, and cheaper compressors. Rotary screw compressors are popular for continuous operation, while […]
HFC gases were developed as a replacement for CFCs, but they contribute to global warming. Scientists are exploring alternatives and working with companies to reduce their release and address environmental damage. An HFC gas is a gas that can be used in a number of different applications. HFCs are commonly used, for example, as propellants […]
Drivers can improve their car’s fuel efficiency by changing their driving habits and maintaining proper car maintenance. This includes avoiding aggressive driving, speeding, and maintaining proper tire inflation. Using cruise control and investing in a tailgate net for pickup trucks can also improve gas mileage. Hybrid and alternative fuel cars offer significant improvements in overall […]
Gas welding uses various gases and oxygen to ignite a torch, melting two materials together. Acetylene is the most common gas used. Skilled operators are needed to ensure a smooth weld, and there are other uses for the oxyfuel torch. Another type of gas welding involves using only one gas without oxygen, which is simpler […]
Gas welding uses gases and oxygen to ignite a torch and combine two materials by heating them until they become molten. Common gases used include acetylene, and a skilled operator is required to ensure a smooth weld. The oxyfuel torch can also be used for cutting metal and other purposes. Another type of gas welding […]
Forming gas is a mixture of hydrogen and an inert gas used in industrial processes to avoid explosion risks. It is used in photographic film preparation, metal welding, and annealing applications. Care must be taken to avoid inhalation and leaks. Forming gas is a mixture of gases that people use in certain industrial processes when […]
Gas turbines convert gas energy into kinetic energy to power machinery. They have a superior power-to-weight ratio compared to reciprocating engines, but are more expensive. A gas turbine engine consists of a compressor, combustion area, and turbine. In airplanes, the turbine shaft rotates the compressor fan to provide thrust. A gas turbine is a rotary […]
Gas traps are used in drainage and piping systems to prevent the escape of gaseous fumes. They rely on structural design rather than filters and can be found in plumbing, natural gas heating systems, and even engines. Dry traps can cause failure, but running fresh water through the lines can restore their filtering action. Gas […]
Gas turbine engines use pressurized gas to turn a turbine and compressor, with fuel being ignited to increase temperature and pressure. The Norwegian engineer Aegidius Elling patented the gas turbine in 1884. The main parts are the compressor, combustion area, and turbine, with a shaft connecting the compressor and turbine. Gas turbine engines have advantages […]
Refinery gas is a mixture of gases produced during the refining of crude oil. Its composition varies and can include butanes, butylenes, methane, ethane, and ethylene. Refinery gas can be sold as a final product, used as fuel, or as a feedstock for other refinery processes. Gas chromatography is used to determine its chemical profile. […]
Increase gas mileage without driving less: tighten gas cap, pump up tires, maintain car, clean out trunk, mix acetone with gas, limit AC use, and walk more. If you’re like most drivers, you’re probably looking for a way to increase your gas mileage and save money. While driving less may seem like an obvious answer, […]
Venezuela has the cheapest gas prices due to government subsidies, costing about 19 cents per gallon. The US consumes the most gas, while Europe has high fuel taxes resulting in high prices. Eritrea has the world’s most expensive gas at $9.58 per gallon. The cheapest gas prices are found in Venezuela. The government subsidizes the […]
Turkey has the most expensive gasoline at $9.98 per gallon, with the average person spending nearly a third of their daily take-home pay on it. Norway has the second most expensive gas at $9.63 per gallon. The United States uses the most gas in the world. Turkey is the country where gasoline is the most […]
Gas guzzlers, such as trucks and SUVs, have low fuel economy and produce high emissions. Governments encourage manufacturers to produce fuel-efficient cars and offer incentives to consumers. Some heavy-duty tasks require gas consumers, but many are designed for unnecessary purposes. Fuel-saving supporters hope to make small, efficient cars stylish and sought-after. A gas guzzler is […]
