The invention relates to compositions, methods of manufacture, and methods for reducing metal corrosion during alkaline cleaning. In particular, the method employs a hydroxyphosphono carboxylic acid in alkaline cleaning of hard surfaces.

Alkaline cleaning compositions comprising a hydroxyphosphono carboxylic acid and methods of reducing metal corrosion

Maleic anhydride homopolymer corrosion inhibitors, maleic acid homopolymer corrosion inhibitors, methods for preparing the same, and methods of inhibiting corrosion are provided. The corrosion inhibitors may exclude phosphorus and may contain a hydrolysate of a maleic anhydride homopolymer or a hydrolysate of a maleic acid homopolymer. The maleic acid homopolymer may include from about 2 to about 5 maleic acid repeating units and the maleic anhydride homopolymer may include from about 2 to about 5 maleic anhydride repeating units.

Maleic anhydride homopolymer and maleic acid homopolymer and methods for preparing thereof, and non-phosphorus corrosion inhibitor and use thereof

Corrosion inhibitors and methods for reducing or inhibiting corrosion of metals in aqueous systems are provided. Corrosion inhibitor compositions may include tetracarboxylic acids, such as butane tetracarboxylic acid. The compositions may include other components, such as zinc, molybdate, silicate, cerium, among others. The compositions may also include polymers or oligomers. The corrosion inhibitor compositions produced synergistic results and unexpectedly low corrosion rates.

Tetracarboxylic acid combinations for corrosion inhibition

Disclosed herein are water-soluble polymers comprising hydrolyzable cross-linked monomer units, and methods for recovering hydrocarbon fluids from a subterranean formation using the water-soluble polymers.

Mobility control polymers for enhanced oil recovery

Emulsions of mobility control polymers can be used to increase recovery of crude oil from a subterranean hydrocarbon-containing formation. A flooding fluid comprising the polymer emulsions are injected into a well that is in contact with the subterranean hydrocarbon-containing formation. The polymers can be temporarily cross-linked and have protected shear degradation and improved injectivity into the well; the shear resistance can be measured in terms of viscosity loss due to shear, and the improved injectivity can be measured in terms of the flooding fluid's filter ratio, flow rate, and viscosity.

Polymer emulsions for use in crude oil recovery

The disclosure relates generally to reducing mercury emissions from a coal power plant. Specifically, a method for treating a gas stream containing mercury is provided that includes injecting a mercury oxidant or absorbent and a carrying agent into a gas stream that was produced by heating or burning a carbonaceous fuel comprising mercury. The carrying agent vaporizes after being injected into the gas stream. The mercury oxidant or absorbent and a carrying agent may be injected before passing the gas stream into a gas scrubber.

Enhanced injection of mercury oxidants

Disclosed herein are polymer compositions useful in high temperature enhanced oil recovery applications. The polymer compositions include at least 20 mol % of an N,N-dialkyl-N,N-diallylammonium salt and further have a net negative charge. The polymer compositions provide polymer dispersions in water or brine having stable viscosity when maintained at temperatures of 100&#xb0; C. and above for at least 2 days.

Thermally stable polymers for enhanced oil recovery

Enhanced oil recovery using mobility control crosslinked polymers

A method of inhibiting hydrates in a fluid comprising water and gas comprising adding to the fluid an effective hydrate-inhibiting amount of a composition comprising one or more homo- or co-polymers of N-alkyl(alkyl)acrylamide synthesized by polymerizing one or more N-alkyl(alkyl)acrylamide monomers in a solvent comprising a glycol ether of formula CH&#x2014;(CH)&#x2014;(O&#x2014;CH&#x2014;CH)&#x2014;OH where m is an integer of 0-1, and n is an integer &#x2265;1.

Method of controlling gas hydrates in fluid systems

Disclosed herein are inversion systems and methods of diluting w/o lattices including about 10 wt % to 80 wt % of a water soluble polymer. Using the inversion systems and methods described herein, dilution of w/o lattices is carried out in a single step to form dilute lattices having 10,000 ppm or less polymer; the dilute lattices form polymer solutions with no further addition of mixing force or water. The solution viscosities of the polymer solutions obtained using the systems and methods of the invention are at least about 80% of solution viscosity expected in the absence of shear.

Apparatus and method for inverting polymer latices

Corrosion inhibitors and methods for inhibiting or reducing corrosion of metallic surfaces are provided. A corrosion inhibitor composition may include a water soluble substituted imidazoline or a hydrolysis product thereof. A method of inhibiting corrosion of a metallic surface in an aqueous system includes the step of contacting the surface with an effective amount of a corrosion inhibitor composition. The corrosion inhibitor composition may include other components, such as zinc, and it may also exclude phosphorus.

Water soluble substituted imidazolines as corrosion inhibitors for ferrous metals

Disclosed herein are methods of increasing retention and drainage in papermaking processes using high molecular-weight, water-soluble polymers.
