A scent presentation system for segregating a desired scent from other scents suspended in a gas. The desired scent has a density that differs from that of another scent in the gas. The system includes a housing having a sloping top wall and a pair of elongated sloping side walls extending downward from the top wall on opposite sides of the top wall. The top wall and the pair of side walls define a channel extending between an upstream end and a downstream end of the housing. The system has a separating gate extending downward into the channel from the top wall to a lower end positioned inside the channel. The gate separates the channel into upstream and downstream chambers. The upstream end has an inlet port allowing the gas to enter the channel, and the downstream end has an outlet port allowing the gas to exit the channel.

A gas sediment trap assembly includes a generally cylindrical length with a generally perpendicular tee and a vertically oriented capped portion. The gas sediment trap assembly is coupled to the gas supply line and the gas fired appliance. One or more gas ball valves can be coupled to the gas sediment trap assembly. The gas sediment trap assembly can be used with conventional gas piping, flexible gas piping, and/or other gas line components.

A fluid treatment system combines cyclonic separators and gravitational separators for use in onshore and offshore oil and gas operations and elsewhere. The characteristics of apertures that interface between a gravitational separation chamber and a cyclonic separator are configurable in accordance with operational requirements. By selecting aperture characteristics, improved control and separation efficiencies can be achieved.
