A method for producing an additive for reclaiming oil from a fluid product stream and a treated silica with controlled hydrophobicity are disclosed. The method includes the steps of providing silica or silicate with a particle size of between 3.0 &#x3bc;m to 20 &#x3bc;m, the silica or silicates having an agglomerate size of between 10 &#x3bc;m to 100 &#x3bc;m and being chosen to achieve the desired particle-size range and with a controlled level of hydrophobicity; treating the silica or silicate with a silicone or silane to make it hydrophobic; and controlling the hydrophobicity of the silica or silicate by varying the temperature and treatment time of the silica or silicate, amount of a treating material used to treat the silica or silicate, and the molecular weight of the treating material. The additive improves oil extraction and concentration from a fluid product stream.

Demulsification compound and method for oil separation from waste streams

The invention relates to a process additive formulation and a method for foam reduction and/or for increasing drainage in a process comprising an aqueous medium. The process additive formulation comprises an acrylate and/or methacrylate copolymer, optionally with acrylic acid or methacrylic acid, in an organic diluent, and mineral oil or vegetable oil.

Process additive formulation and method for foam reduction and/or for increasing drainage

Cement compositions and processes for reducing air entrainment in a cement composition generally include mixing a hydraulic cement with a defoamer compositions including one or more organic acid ester polymers selected from an organic acid ester of polyethylene oxide polymer, an organic acid ester of polypropylene oxide polymer, and a mixture thereof. The compositions may further comprise an organic acid ester of an ethylene oxide-propylene oxide block copolymer.

Defoaming compositions

Disclosed herein are methods of defoaming industrial process streams, the methods comprising adding to the industrial process stream an emulsion comprising silicone emulsion droplets in a continuous aqueous phase. Also disclosed herein are defoamer compositions comprising these silicone emulsions and methods of making such compositions.

Defoaming compositions comprising hydroxy terminated siloxanes and methods of making and using the same

Cement compositions and processes for reducing air entrainment in a cement composition generally include mixing a hydraulic cement with a defoamer composition including an organic acid ester of a polyoxyethylene-polyoxypropylene block copolymer.

Defoaming compositions and processes for cementing applications

A polyester surfactant includes a condensation esterification product of a) a polyhydric alcohol, b) a dimer or trimer of an C2 to C42 acid, and c) polyethylene glycol and polypropylene glycol. The polyhydric alcohol is selected from glycerol, arabitol, sorbitol, sorbitan, mannitol, mannitan, erythritol, pentaerythritol, or mixtures thereof. The polyester surfactant is used for deinking, for example, printed waste paper. A method for deinking includes a step of contacting an aqueous pulp slurry with the addition of a composition comprising a polyester surfactant.

Polyester surfactants for deinking

The present invention relates to cost-effective and environmentally friendly polyester surfactants for use in flotation deinking. The improved ink collection of the present invention can result in deinked pulp of high quality and/or yields that has excellent brightness and effective residual ink concentration values.

The present invention relates to a cost-effective and environmentally friendly polymeric defoamer formulation for use in various industrial applications that does not contain oil, EBS or free silicone.

Polymeric defoamer additive

The present invention relates to cost-effective and environmentally friendly polyester surfactants containing a condensation esterification product of a polyhydric alcohol, a multimeric acid, and at least one polyalkylene glycol for use in flotation deinking under traditional alkaline, reduced alkali, and true neutral deinking conditions. The polyester deinking surfactants of the present invention will effectively exhibit greater selectivity than traditional flotation deinking surfactants. In particular, the polyester deinking surfactants can give better foam control, improved yield, and no loss in ERIC reduction.
