What is the purpose of dry gas seal? – Short-Fact

WebDry gas seals are mechanical seals but use other chemicals and functions so that they do not contaminate a process. These seals are typically used in a harsh working environment such as oil exploration, extraction and refining, petrochemical industries, gas transmission and chemical processing. WebTo isolate gas seal cavity from the oil bearing cavity a separation seal is used. Dry nitrogen or air is provided to a separation seal to isolate the dry gas seal cavity from the oil bearing cavity and prevent oil ingress into the seal. Some seals commonly used as separation seals are segmented carbon ring seals and split labyrinths. how do you know if it is a redox reaction
