Why measure oxygen partial pressure? The oxygen partial pressure can be used to calculate the water vapor content, that is, the oven is working properly and calculate the current relative humidity in the box. Relative humidity RH% = (WVP ÷ WVPmax) x 100% = {[BP-(ppO2÷0.2095)]÷ WVPmax} x 100% in: WVPmax is the saturated water vapor…
Industrial safety is an issue that every production enterprise must pay great attention to, especially in industries involving toxic and harmful gases, such as metal processing, electroplating, textiles, chemical pharmaceuticals, etc. Hydrogen cyanide, as a highly toxic gas, is widely used in these industries, but it also brings great safety risks to workers. Therefore, the…
Air is compressible. Air that has been compressed by an air compressor to reduce its volume and increase its pressure is called compressed air. Compressed air is an important source of power. It is different from other compressed air, that is, air compressed by external force. With the widespread application of compressed air, different industries…
Water conservancy and hydropower projects are renewable energy and one of the main projects for sustainable development. The rational use of natural resources and the effective use of water conservancy and hydropower project-related equipment are indispensable to promoting and achieving sustainable development. Gates play an irreplaceable and important role in the construction of water conservancy…
Hydrochloric acid is an aqueous solution of hydrogen chloride ( HCl). It is a monovalent inorganic strong acid. It is a colorless and transparent liquid with a strong pungent odor and high corrosiveness. Concentrated hydrochloric acid (concentration is about 37%) is extremely volatile, and fiberglass is usually used for storage . As a widely used…
With the continuous development of science and technology , coal mine safety issues have attracted more and more attention. In order to ensure the safety of miners, coal mining companies need to take a series of safety measures. Among them, oxygen content is one of the important factors affecting coal mine safety. Oxygen itself is…
With the transformation of the global energy structure and the increasing awareness of environmental protection, the transportation demand for liquefied natural gas (LNG), as a clean and efficient energy, is growing day by day. As a special ship designed to transport liquefied natural gas, the safety and reliability of LNG ships are directly related to…
In the modern chemical production process, the preparation of high-purity gas is a key link in many technological processes. As an efficient oxygen removal equipment, the waste nitrogen deoxygenation device plays an irreplaceable role in the production of high-purity gas. At the same time, in order to ensure the stability of the production process and…
As the petrochemical industry plays an increasingly important role in the national economy, especially the wide application of synthetic materials, a problem that cannot be ignored has gradually surfaced – petrochemical odor gas. These pollutants with pungent odors not only have a serious impact on the surrounding environment, but also threaten people’s health. Odorous pollutant…
Coal is a pillar industry in the development of China’s national economy. When it comes to coal mine killers, words such as “gas explosion”, “water penetration” and “collapse” will most likely come to everyone’s mind. In fact, behind these disasters there is also a very scary “” Killer” – dust. Coal will produce a large…
