    Abstract: Disclosed is a method comprising: a) dispersing lignin into an alcohol-containing compound having a boiling point in the range of 120° C. to 300° C. to form a lignin dispersion; and b) contacting the lignin dispersion with an alkylene carbonate, optionally in the presence of a basic compound, at a temperature in the range of from 120° C. to 200° C. and a period of time in the range of from 0.25 hours to 24 hours to form an alkoxylated lignin dispersion.

    Abstract: The implementations described herein generally relate to methods and chemical compositions for scavenging sulfur-containing compounds, and more particularly to methods and compositions for scavenging, for example, H2S and mercaptans from sulfur-containing streams. In one implementation, a method for scavenging a sulfur-containing compound from a sulfur-containing stream is provided. The method comprises contacting the sulfur-containing stream with a scavenging system for scavenging the sulfur-containing compound, wherein the scavenging system comprises urea formaldehyde reaction products.

    Abstract: Proppant materials, and methods for making proppant materials, are provided. In one embodiment, the proppant material comprises a substrate material, a polymeric material disposed on the substrate material, a surface wettability modifier disposed on the polymeric material, and a surfactant material disposed on the surface wettability modifier. A consolidation material may also be disposed on the polymeric material or formed as part of the polymeric material.

    Abstract: Some implementations of the present disclosure prevent, reduce or at least slow equipment fouling using passivation as a treatment prior to contacting metallic components with hydrocarbon containing fluid, that is, an environment where fouling occurs. For example, one implementation includes a method of passivating heat exchangers in a SAGD process or system using the compositions and compounds of the present disclosure. The composition may be applied to a component prior to its first inclusion in an online system or following placing the system offline for maintenance. The composition may be used to treat metallic equipment surface(s), for example, via contacting them with a suspension or solution of the composition described herein, prior placing the system online. The method may further include treatment of the process fluid, for example, via injection or batch treatment of the composition with the compositions described herein into the process fluid.
