Claim 8:
9. A catcher configured to connect to a flare boom of a drilling or production rig, the flare boom configured to combust at least a portion of hydrocarbon fluids flowed from the flare boom to the rig, the catcher comprising:
a diverter positioned to divert a flow of uncombusted hydrocarbon liquids from the flare boom, a top edge of the diverter partially defining an opening, the catcher configured such that a combustion plume of a flare from the flare boom can enter the opening when the catcher is connected to the flare boom, the diverter comprising a back portion that is arcuate in shape and i-s-configured such that the uncombusted hydrocarbon liquids spraying upward from the flare boom strike the back portion and are thereby diverted, and wherein a bottom edge of the diverter partially defines a vent passage beneath the diverter, and wherein the catcher is configured such that, during low flow-rate scenarios, gas flowing from the flare boom rises above a top edge of the diverter over the top of the catcher and, during high flow-rate scenarios, gas flowing from the flare boom is at least partially diverted by the back portion of the diverter and travels through the vent passage to exit the catcher out the back of the catcher;
and
a container configured to receive the uncombusted hydrocarbon liquids diverted by the diverter.
