摘要： Methods and compositions for suppressing fugitive dust are provided herein. To suppress fugitive dust, particulate materials, dust and or substrates can be treated with a mixture having a hydrophobizing agent and an oil. The hydrophobizing agent can be an organo- or halosilane, a tallow alkylamine, an amine-functionalized polysiloxane, or an amine-functionalized hydrophobic polymer.

摘要： A proppant slurry is formed by lifting dry proppant using one or more augers and distributing an additive to modify the dry proppant as it falls from the top of the augers into a blender tub. Water is added to the blender tub and the modified proppant for forming the proppant slurry. The additive hydrophobically modifies surfaces of the proppant, typically sand, to produce stable proppant/bubble aggregations for forming proppant packs when introduced into formation fractures. The additive is distributed using main spray nozzles directed downwardly onto the falling proppant in a direction of fall of the proppant. Auxiliary spray nozzles protrude upwards into the proppant and distribute additive within and beneath the falling proppant and in a direction of travel thereat. Spray orifices further distribute additive to the falling proppant.

摘要翻译： 通过使用一个或多个螺旋钻提升干支撑剂并分配添加剂来形成支撑剂浆料，以在干燥支撑剂从螺旋钻的顶部落入搅拌器桶中时改变干支撑剂。 向搅拌桶和改性支撑剂中加入水以形成支撑剂浆料。 添加剂疏水改性支撑剂的表面，通常是砂，以产生稳定的支撑剂/气泡聚集体，用于在引入地层裂缝时形成支撑剂组合物。 添加剂使用主喷雾喷嘴沿着支撑剂坠落的方向向下指向落下的支撑剂。 辅助喷嘴向上突出到支撑剂中，并将添加剂分布在落下的支撑剂内和下方，并沿其行进方向。 喷孔进一步将添加剂分散到落下的支撑剂中。
