Abstract: A method of drying liquid and gaseous hydrocarbons by contacting a feed stream of the hydrocarbon with an aqueous solution of a salt drying agent prior to passing the stream through a salt dryer to remove part of the water in the stream. The aqueous solution of the salt drying agent is generated in the salt dryer when the partly dried stream comes into contact with the drying salt and forms the solution. The solution is circulated in a loop from the salt dryer to the incoming feed and then through a liquid/liquid coalescer which removes a portion of the water together with dissolved salt from the mixture before the mixture is passed on to the salt dryer where further removal of water occurs. The salt dryer is off-loaded by a substantial factor by the initial partial dehydration and does not require to remove such a large amount of water; the salt consumption is therefore reduced in proportion to the amount of water removed in the treatment steps which precede the dryer.

Abstract: An air scrubber for removing oils and contaminates from air has an underside inlet for the introduction of contaminated air. The contaminated air passes through a reduced aperture passageway which prevents retrograde flow of contaminates or cleaning fluids contained in the scrubber. The contaminated air is thereafter directed upwards through a scrub reservoir having a plurality of apertures, such that the contaminated air passing through the apertures forms jets which cause interaction between the cleaning fluid and the contaminates, thereby creating droplets containing cleaning fluid with entrapped contaminates, and cleaned air. The droplets and air are directed to a mist eliminator having a plurality of chevron V structures which capture the droplets and return them to the main reservoir. A circulating pump moves cleaning fluid from the main reservoir to an upper reservoir which spills into the cleaning reservoir.

Abstract: A weld chamber has an air intake and an exhaust or evacuating ductwork for evacuating gases and other particles from the welding chamber. The evacuating ductwork is connected to a vacuum source to remove gases and by products from the weld chamber during welding. A throttle plate is provided in the evacuating ductwork adjacent the weld chamber to adjust or regulate the air velocity evacuating from the weld chamber. The evacuating duct then leads to a sealed water filtering tank. All of the exhausted/evacuated gases and by products are led beneath the water line and bubble through the water before emerging from the sealed water. The soot and iron particles are immediately cooled and trapped in the water tank. Moreover, particles become wet and are less likely to become airborne thus leading to a substantial portion of the particles being trapped in the sealed water tank. Thee remaining gases are then evacuated to the vacuum source and further filtered by a mechanical filtration device.
