Industrial gases are chemicals that are used in technological processes for various purposes. Gases are created by forced reaction chemical substances. At the end of 2016, the global market technical gases in value terms amounted to $83 billion.
The most common industrial gases are:
- ordinary air. It is based on a mixture of nitrogen and oxygen. Nitrogen is used as a refrigerant and for cryotherapy in medicine (destruction of cells by freezing). Oxygen is mainly used in medicine as the main element of respiratory gas mixtures in anesthesia equipment. The air has a small admixture of argon and xenon;
- carbon dioxide. A secondary product released during combustion. Carbon dioxide is the exhaled air of all living organisms on earth;
- hydrogen. A light chemical element, its use is relevant not only in industrial, but also in the chemical and food industries;
- acetylene. It has a high explosion hazard and is used in gas welding and metal cutting;
- helium. It has no toxic properties, is a light gas, does not burn, and has superfluidity. Used in metallurgy for smelting high-quality pure metal,
Industrial gases are transported to consumers through pipelines or special cylinders.
Production of industrial gases
Technical gases are obtained by combining chemicals. Oxygen and nitrogen are often used for this.
To obtain atmospheric industrial gases (oxygen, nitrogen and argon), air separation technology is used. Cryogenic air separation involves passing it through multi-stage purification equipment.
The short-cycle adsorption method is based on the selective absorption of the required gas by adsorbents.
Membrane gas separation technology dates back to the 1970s. The high efficiency and cost-effectiveness of this technology made it an excellent alternative to the first two methods.
Hydrogen is produced by steam reforming and electrolysis using special equipment.
Gas-powered industrial equipment
The main use of technical gases is noted in the field of water heating - these are industrial water heating boiler plants with high efficiency. Gas-powered industrial equipment are devices in which, as fuel material use gas. Industrial gas-powered equipment is used for production purposes and for district heating population.
Manufacturers and suppliers of industrial gas equipment
- The Promgaz plant specializes in the production of transportable boiler systems and equipment for gas metering and purification of petroleum products;
- The Gazsintez plant provides services for the production of boiler houses and heating units for liquefied gas;
- Kamensky Gas-Using Equipment Plant, a subsidiary of Gazprom Promgaz JSC, produces gas control and gas-using equipment;
- JSC "Savo" - production infrared heaters on gas;
- PKF "Ex-Forma" produces gas-powered industrial equipment;
- Gazovik Group of Companies - production industrial equipment on gas, equipment for cutting pipes, capacitive and technological equipment for liquefied hydrocarbon gases.
Industrial gas boilers
Industrial gas boilers include gas-fired hot water boilers, combi boilers(gas-diesel).
Industrial gas boilers are used:
- for hot water supply;
- for heating residential premises;
- to provide process steam to production enterprises.
Hot water boilers using industrial gas
Hot water gas boiler is boiler equipment high power for supplying hot water and heating. Industrial gas hot water boilers can be mounted or floor-mounted. The latter are more powerful.
Factories where you can buy industrial gases
Sales of technical gases in our country at the end of 2016 amounted to 21.2 billion rubles. Industrial gases are sold by companies such as:
CJSC Kubantekhgaz is the largest enterprise in the south of Russia, specializing in the production of oxygen, nitrogen, argon;
PJSC "Cryogenmash" produces different kinds equipment for the production, transportation and storage of technical gases;
OJSC "Sibtekhgaz", Novosibirsk - one of the leading enterprises in Russia and the CIS for the production of technical gases: oxygen, argon, highly pure gases, nitrogen, food and technical gas mixtures;
Khimstandart LLC, Moscow - is a manufacturer of fine organic synthesis products in the cosmetics industry, dyes, pharmaceutical substances, products for oil production, and fine chemicals.
The choice of LPG can be divided into two groups. In the unambiguous top will be the leading manufacturers of LPG systems (all, as has historically happened, with Italian roots). They either completely produce all the components for installation kits, or use third-party parts to a minimum (most often these are electronic control units). The resulting kit is quite expensive, but reliable and of high quality.
But there are also many companies that produce exclusively individual gas equipment parts - for example, from high-quality Hana injectors to Chinese “no-name”. So it is not surprising that assembly companies appear that simply assemble kits from various parts. Without the need to create a network of branded representative offices and authorized services, which gives a significant increase in the prices of kits from top-level brands, assembly companies can additionally save on the parts themselves. More critical ones can be purchased at a higher price, and less critical ones can be purchased cheaper. As a result, such a whale will be noticeably more attractive in price. And, by the way, as is the case with manufacturers of HBO systems high class, here the geography is also quite defined: most of the order pickers Russian market originally from Poland.
Should I contact the order pickers or not? In fact, when using high-quality parts, this will save money without wasting resources. But immediately familiarize yourself with what parts are used in a particular kit: it’s one thing if the brands are honestly indicated, but “your own brand” or its complete absence most likely indicates Chinese components of unknown quality.
Regardless of the brand of kit, select it correctly for your motor. The performance of the gearbox must correspond to the power of the engine, otherwise at peak load conditions the engine will begin to “choke”, not receiving enough fuel. It is highly desirable to be able to fine-tune fuel maps in the ECU of gas equipment, this will allow you to get the best power and efficiency. If the opening time of standard gasoline injectors at idle is less than 2 milliseconds, the “brains” of the gas injector must be able to calibrate the opening/closing time of the gas injectors, otherwise rebuild idling it'll be hard. Don’t forget about the ignition variator: gas burns completely differently than gasoline, and at “gasoline” ignition angles it will burn out already in the exhaust manifold, overheating the catalyst and exhaust valves. In addition, the ignition variator also provides a noticeable increase in dynamics.
