Produced water can contain both soluble and insoluble organic compounds. Discharge of some of the materials in both classes are regulated as pollutants. What is regulated and how it is measured varies by jurisdiction. In most of the waters of the Western Hemisphere, discharge of oil in water is governed by the U.S. standard as measured by U.S. EPA Method 1664 Revision B: n-Hexane Extractable Material and Silica Gel Treated n-Hexane Extractable Material by Extraction and Gravimetry (EPA 1664B). The “Hexane Extractable Material” (HEM) is the residue of compounds which extract into n-hexane from water at pH < 2 after evaporating the solvent. This is also known as the Total Oil & Grease (TOG). This extract is limited to a 29 mg/L yearly average. It includes polar components of crude oil which are not strictly hydrocarbons. Some of these polar compounds are soluble in the produced water at its native pH and can’t be removed with simple separation of the immiscible oil and water phases. The natively water-soluble portion of the TOG is referred to as “Water-Soluble Organics” (WSO). Removing WSO to meet TOG specifications requires desolubilizing them with special reagents. The measurement, regulation, and removal of WSO in produced water will be addressed in detail in this webinar.
