Various embodiments of the present disclosure provide an inertial separation device, system, and method. The inertial separation device includes an inlet nozzle coupled to an expansion chamber. A sample outlet and an outlet port are coupled to the expansion chamber. In operation, a fluid sample passes though the inlet nozzle and is expanded in the expansion chamber such that the sample is separated into at least two fractions having different masses, a selected mass fraction passing through the sample outlet and a remaining portion of the sample passing out of the outlet port. A system including the inertial separation device includes a conduit coupled to the sample outlet nozzle and a detector coupled the conduit. The inlet nozzle may be, for example, coupled to an emissions source.

Various embodiments of the present disclosure provide a sampling device, system, and method. The sampling device includes a sample inlet nozzle fluidly coupled to a dilution body. A carrier fluid delivery conduit is also fluidly coupled to the dilution body. In one implementation, the carrier fluid delivery conduit is coupled to a source of heated carrier fluid. Carrier fluid is delivered around a perforated portion of the sample inlet nozzle, in one configuration. In some cases, the sampling device includes a mixing device configured to produce laminar flow of carrier fluid about a fluid sample. In other cases, the mixing device produces turbulent flow of carrier fluid and fluid sample. Systems including the sampling device include, in some implementations, a sample separator, such as an inertial droplet separator. In further implementations, systems including the sampling device further include an atmospheric dispersion simulator.

A method for oxidizing odorous constituents of contaminated gas with minimum consumption of the oxidizing agent. Apparatus is disclosed for causing contact between the contaminated gas and the scrubbing liquid by means of opposed flow through a porous bed of packing material. The method is primarily useful in controlling odorous emissions from rendering plants, fish processing plants, asphalt plants, and other plants in which aldehydes, fatty acids, ketones, mercaptans, amines, hydrogen sulfide, sulphur dioxide, nitric oxide, phenols or other pollutants are emitted. Chlorine in the form of sodium hypochlorite in a concentration of 5-50 ppm is the preferred oxidizing agent. Consumption of the oxidizing agent is minimized by continuously purging 1-5% of the scrubbing liquid to thereby promptly remove precipitates and other solids.

An electrostatic precipitator assembly is disclosed. The assembly includes a tubular collector and an electrode suspended therein. The electrode includes a substantially cylindrical collector portion and a charging portion which includes a rod and a charging disk, wherein the gap between the charging disk and the collector is at least as great as the gap between the collector portion of the electrode and the collector.
