A high-integrity pressure protection system (HIPPS) is a type of safety instrumented system (SIS) designed to prevent over-pressurization of a plant, such as a chemical plant or oil refinery. The HIPPS will shut off the source of the high pressure before the design pressure of the system i...
본 이송방식은 고압의 압축공기를 이용하여 원료를 이송 하는 방식으로 저압압송방식과 비교하여 설비의 구조는 크게 다르지 않지만 공기원 기기가 공기압축기(콤푸레셔) 로 사용되어 고압의 압력 (약 2~5kgf/㎠)이 발생하여 이송되므로 원료를 공기압송기 (TRANSPORTER) 등과 같은 고압용 탱크류에 저장하여 이송합니다. 이송계통은 공기압송기에 압축공기를 분사하여 압력이 부유된 상태에서 원료와 함께 이송되며 압 ...
When surface winds become light, the subsidence produced directly under a high-pressure system can lead to a buildup of particulates in urban areas under the ridge, leading to widespread...
A pressure system is a peak or lull in the sea level pressure distribution. The surface pressure at sea level varies minimally, with the lowest value measured 87 kilopascals (26 inHg) and the highest recorded 108.57 kilopascals (32.06 inHg). High- and low-pressure systems evolve due to int...
When the weather is dry, tranquil and nice, you can typically thank high pressure systems for keeping stormy and rainy weather at bay.

Above every square inch on the surface of the Earth is 14.7 pounds of air. That means air exerts 14.7 pounds per square inch (psi) of pressure at Earth’s surface. High in the atmosphere, air pressure decreases. With fewer air molecules above, there is less pressure from the weight of the air above. Pressure varies from day to day at the Earth’s surface - the bottom of the atmosphere. This is, in part, because the Earth is not equally heated by the Sun. Areas where the air is warmed often have lower pressure because the warm air rises. These ...

The high-integrity pressure protection system is an independently instrumented system that protects downstream systems from overpressure by reliably isolating the source of overpressure, reducing t...
