节流器下游碳氢化合物处理和分离设备中固体的存在会对工艺可操作性、资产风险和流量保证产生重大影响，从而影响运营经济性。在整篇论文中，研究了固体颗粒对油/水（O/W）分离器（即乳液稳定性）和采出水处理的影响。
在本研究中，选择了六种不同的固体，其中三种代表储层固体（砂、伊利石和高岭石），三种代表水垢和腐蚀固体[碳酸钙 (CaCO 3 )、硫酸钡 (BaSO 4 ) 和硫化铁 (FeS) ]。所有使用的固体都在成分和尺寸方面进行了表征；对于改性固体，还测量了它们的润湿性。砂样完全被水润湿，而CaCO 3和BaSO 4的润湿性无法测量。对于其余颗粒，接触角低于90°显示出水润湿特性。

The presence of solids in hydrocarbon treatment and separation equipment downstream of the choke can have a significant effect on process operability, assets risks, and flow assurance, therefore affecting operational economics. In the complete paper, the effect of solid particles on oil/water (O/W) separators (i.e., emulsion stability) and on produced-water treatment has been studied.
In this study, six different solids were chosen, three representing reservoir solids (sand, illite, and kaolinite) and three for scale and corrosion solids [calcium carbonate (CaCO3), barium sulfate (BaSO4), and iron sulfide (FeS)]. All solids used were characterized in terms of composition and size; for modified solids, their wettability also was measured. The sand sample was fully water-wet, while the wettability of the CaCO3 and the BaSO4 could not be measured. For the rest of the particles, contact angles lower than 90° showed water-wet properties.
A crude oil from offshore Brazil was used.
