摘要： Methods are provided for separating algae from an aqueous environment. An aqueous feed containing algae can be aged for a period of at least about 90 hours without purging or other aeration. The aging of the aqueous feed can result in formation of aggregated algae, which can then be filtered under pressure. Due to the larger size of the algae aggregates, the pressurized filtration can reduce/minimize the tendency to clog the filter, as the algae aggregates can generally be too large to fit within the pores of the filter. The filter can preferably be located at the bottom of the vessel holding the aqueous feed. This can assist in allowing the algae to remain in a cake above the filter, as opposed to having the algae dissolve back into the aqueous feed.

The alkyl acid surfactant has the general formula {R—X}, wherein R comprises at least one of linear and branched alkyl and alkyl aryl hydrocarbon chains and X comprises an acid, and X may comprise an acid selected from the group comprising sulfonic acids, carboxylic acids, phosphoric acids, and mixtures thereof. The alkyl acid may include an acid selected from the group consisting of alkyl or alkyl aryl acids. The operations fluid may be useful in treatment operations related to formation stimulation or mitigation of non-aqueous filter cakes (NAF) and/or formation invasion by NAF drilling fluids.

摘要： A novel composition is provided that incorporates the residual solids from solvent deasphalting to make a high value asphalt product. A process for making the asphalt composition is also provided. A first portion of heavy oil or another feedstock can be deasphalted using propane deasphalting or another suitable deasphalting process. This generates a solvated fraction and an insoluble deasphalting residue. The deasphalting residue is then added to a second portion of heavy oil, such as a second portion of the same type of heavy oil that was used as feedstock in the solvent deasphalting. The mixture of deasphalting residue and heavy oil results in a novel dispersion that is suitable for use as an asphalt. Optionally, an additive such as an alkyl substituted aromatic sulfonic acid can be added to the composition to further improve the asphalt properties.
摘要翻译： 提供了一种新的组合物，其包含来自溶剂脱沥青的残留固体以制备高价值沥青产品。 还提供了制备沥青组合物的方法。 重油或其他原料的第一部分可以使用丙烷脱沥青或其它合适的脱沥青方法脱沥青。 这产生溶剂化馏分和不溶性脱沥青残渣。 然后将脱沥青残渣加入重油的第二部分，例如在溶剂脱沥青中用作原料的相同类型重油的第二部分。 脱沥青残渣和重油的混合物产生适合用作沥青的新型分散体。 任选地，可将添加剂如烷基取代的芳族磺酸加入到组合物中以进一步改善沥青性能。
