使用交叉流过滤处理原油的方法及系统;METHODS AND SYSTEMS FOR PROCESSING CRUDE OIL USING CROSS-FLOW FILTRATION

摘要

用于处理原油之方法及系统包含：将水添加至该原油，以产生包含盐水及油以及固体之乳液；自盐水分离油，此操作包括产生包含一石油乳化样品层之盐水；将该石油乳化样品层分离成具有较细固体之烃乳液及包含较大固体之盐水；及沿着一交叉流过滤器传递该烃乳液，以产生包含盐水及固体之保留物及包含烃之渗透物。; separating oil from brine including producing brine comprising a rag layer; separating the rag layer into a hydrocarbon emulsion having finer solids and brine comprising larger solids; and passing the hydrocarbon emulsion along a cross-flow filter to produce a retentate comprising brine and solids and a permeate comprising hydrocarbon.
