Abstract: An additive comprising one or more C3-C12 hydroxycarboxylic acids and/or one or more C3-C12 hydroxycarboxylic acid salts may be added to an aqueous system having galvanized metallurgy or a carbon steel surface in an effective amount to passivate a galvanized coating on the metallurgy or to decrease white rust formation or other types of corrosion upon the galvanized metallurgy or carbon steel surface in an aqueous system. In a non-limiting embodiment, the C3-C12 hydroxycarboxylic acid or the C3-C12 hydroxycarboxylic acid salt additive may utilize the zinc in the galvanized coating to achieve passivation. The passivation may occur while the system is shut down or in service. The aqueous system may be or include a cooling tower, a cooling water system, and combinations thereof. The additive may be used with or in the absence of a phosphorous-containing compound.

Abstract: A fire kindling device and method having a wick and a coated fuel material strip. A user loosely rolls the coated fuel material strip into a spiraled cylindrical coil defining and creating a gap between radially spaced sections. The user places the spiraled cylindrical coil in an upright position, presses the wick into a centrally located apex point over the radius of the spiraled cylindrical coil and down the exterior side wall and then stacks combustible kindling material around the spiraled cylindrical coil. The wick is ignited, igniting the fire fuel causing the fire fuel to ignite the coated fuel material strip within the spiraled cylindrical coil, thereby causing a kindling fire. The sections are ignited nearly simultaneously, igniting the combustible kindling material. The fire fuel transforms into a combustible gas within the gap, augmenting combustion of the fire fuel, and increasing the temperature of the kindling fire.

Abstract: A method of filtering a fluid with components includes providing an alternating pressure. The alternating pressure yields an oscillating transmembrane pressure through volume and pressure variations within a filtration chamber while sealing the filtration chamber. A separation surface can be housed in the filtration chamber wherein an influent is introduced. Components can be concentrated on the separation surface, effectively removing some or all of them from the fluid. To flush the filtration chamber and separation surface, a backwash fluid and components can be introduced and removed from the filtration chamber. While both the components are being concentrated and backwashed, the system can maintain the oscillating transmembrane pressure and varying volume and pressure relative to the separation surface.

Abstract: Methods for making efficient use of steam in a steam-assisted gravity drainage (SAGD) process for recovering heavy oils from tar sands and similar petroleum deposits are disclosed. The methods utilize a surfactant to generate steam foam in ways that maximize efficient use of steam. In some aspects, steam foam is used in water layers or gas caps that reside above steam chambers to prevent loss of steam from the steam chamber. The predominant use of relatively dry steam in SAGD processes makes it challenging to find ways to introduce surfactants and generate steam foam. However, decreasing the mobility of the steam by converting at least some of it to foam allows the wellbore and steam chambers above the injection site to be more fully developed, provides for more effective heat transfer to the heavy oil and rock, improves production, and allows recovery of the heavy oil with a minimum amount of steam usage.

Abstract: The present invention is directed to both a method for ensuring optimal conditions for separation, and a separator device for extraction of water, oil and gas from a mixture of water-oil-gas flowing in a straight pipe or straight channel. A separator comprises a certain length of pipe with diameter larger than or equal an inlet pipe and several inclined and profiled holes along the separator pipe wall. Holes in the pipe wall at the bottom of the pipe are provided for extraction of water, and one or more groups of inclined holes in the pipe wall at the top of the pipe are provided for extraction of oil and possible gas. Water and oil/gas are separated such that dispersed flow in the inlet is reduced to velocity equal or less than that of the separated flow at the outlet of the separator.
