Or vapor combustion units, are installed in applications where there is a mixture of vapors (HC-air) in which it is not possible or economical to recover the hydrocarbon fraction.
The combustion system can safely combust the stream, minimizing feed gas consumption and complying with the strictest safety standards, applying ATEX regulations that require different chain protection measures.
Depending on the frequency of the risk, they are classified as Zone 0 (incorporating three independent protection measures) or Zone 1. Control loops with SIS-SIL safety systems are typical, depending on the risk analysis.
Typically applied to vapors where the gases to be treated are explosive (gas mixtures diluted in air at concentrations between LEL and UEL). They are commonly used in the degassing of tankers or storage tanks.
