Abstract: Methods and dispersing agents for dispersing a polymeric low dose hydrate inhibitor are disclosed. More specifically, the method comprises contacting an aqueous fluid containing a polymeric low dose hydrate inhibitor with a dispersing agent. The dispersing agent can be selected from the group consisting of a C1-C20 alkyl sulfate, a C10-C20 alkyl ether sulfate, a C10-C20 carbonyl sarcosinate, a C10-C20 alkylbenezene sulfonate, a quaternary-ammonium based corrosion inhibitor, a glycol ether, and a combination thereof.

Abstract: A method for manufacturing a dye scavenging substrate which comprises the steps of: (a) providing an absorbent substrate; (b) passing the substrate through a bath containing an alkaline solution of a dye scavenging compound selected from: (i) a N-trisubstituted ammonium-2-hydroxy-3-halopropyl compound having the general formula (I), or (ii) a salt of epoxy propyl ammonium having the general formula (II), or a combination thereof; (c) subjecting the substrate to a pressure of from about 0.04 MPa to about 0.40 MPa; (d) wrapping the substrate in a water impermeable material and rotating the substrate for a period of from about 12 hours to about 60 hours; (e) removing the water impermeable material and passing the substrate through a bath containing an acid solution; (f) subjecting the substrate to a pressure of from about 0.15 MPa to about 0.40 MPa; and (g) drying the substrate.

Abstract: A method of tubing manufacture comprising forming a tube having an internal artifact projecting radially inward from a tube inner surface, retaining the tube in a fixture, broaching an end of the tube to remove a longitudinal portion of the internal artifact which longitudinal portion is less than a total length of the tube, finishing the radius of the internal artifact so it is substantially equal to a radius (R1) of the adjacent inner surface, and forming a single flare on the end of the tube.

Abstract: A scavenging substrate comprising an absorbent substrate bearing a soil scavenging compound having the formula (I), wherein R1 and R2 are each independently hydrogen, C1-5-alkyl or phenyl, X? is an anion, Y+ is a cation, m is 1-5 and n is 30-5000; and, optionally, a dye scavenging compound selected from the following compounds: (i) N-trisubstituted ammonium-2-hydroxy-3-halopropyl compound having the formula (II).

Abstract: A method for the production of a dye scavening substrate which comprises the steps of: (a) providing a cellulosic substrate; (b) passing the substrate through a bath containing an alkaline solution of an N-trisubstituted ammonium 2-hydroxy-3-halopropyl compound having general formula (I) or a salt of epoxy propyl ammonium having general formula (II), wherein X is a halogen radical, Y is a chloride, bromide, sulfate or sulfonate, and the R's are methyl, ethyl, butyl or benzyl groups or an hydroxyl substituted derivative thereof; (c) subjecting the substrate to a pressure of between 0.69-1.37 MPa (100-200 psi); (d) heating the substrate to a temperature of approximately 35.degree. C.; (e) wrapping the substrate in a water impermeable material and rotating the material at a temperature of between 15.degree. C. and 100.degree. C.
