Abstract
A flare gas system for flaring high and low pressure flare gases, the system including a first flare gas assembly that has a central air pipe and first and second conduits in surrounding relationship to the air pipe. There is a first annulus formed between the air pipe and the first conduit, and a second annulus formed between the first conduit and the second conduit. A flow restrictor is disposed in the second annulus. A first gas handler conveys a first flare gas to the first flare gas assembly. A second flare gas assembly is connected to the first flare gas assembly and has a tubular housing in which is disposed a pressure operated valve assembly. A second flare gas handler distributes a second flare gas between the second annulus and the tubular housing. A single igniter can be used to ignite the gas from the first flare gas assembly and multiple second flare gas assemblies.
