Electromagnetic Flow Meter Applied in Oilfield Wastewater

Wastewater accurate measurement and control of the volume of discharged wastewater, chemical additives, and sludge are crucial in the wastewater treatment process. For this purpose, it is essential to measure the flow rate of the wastewater, including oilfield wastewater.

Site Situation

Detailed composition analysis is a necessary step prior to wastewater treatment. In an oilfield setting, there is both regular wastewater and drilling well wastewater.

• Ordinary Wastewater

The main composition consists of water, secondary clay minerals, RSH, RSR, RSSR, etc.

As the ordinary wastewater contains many impurities and strong acidity/alkaline, the electromagnetic flowmeter chosen shall be made with rubber or PTFE lining, together with stainless steel electrodes.

• Drilling Well Wastewater

The main composition consists of well-drilling liquid and well-cleaning liquid. The main contaminants are drilling cuttings, petroleum, viscosity control agent (like clay), weighting agent, clay stabilizer, corrodent, preservative, bactericide, lubricant, stratigraphic affinity, defoamer, etc., and other elements like heavy metals in the drilling well wastewater as well.

Considering the complex composition, strong acidity or alkalinity, corrosiveness, and presence of heavy metal ions in drilling well wastewater, it is crucial to select an electromagnetic flow meter with appropriate materials for optimum stability and performance. Preferred choices include a flow meter with PU or PFA lining, along with Tantalum or Hastelloy electrodes.

Solutions

Oilfield wastewater, whether ordinary or from drilling wells, exhibits varying ranges, impurities, and weak corrosiveness. Both types contain many ions with high electrical conductivity and are not influenced by factors like temperature, pressure, and viscosity. Due to these considerations, an electromagnetic flow meter is an ideal solution for accurately measuring the flow rate of oilfield wastewater. For large-diameter wastewater measurements, the flow meters are typically of the separate type, with the sensing part installed underground and the electrical part installed above ground. Conversely, smaller-diameter flow meters are predominantly of the integrated type. Electromagnetic flow meters, especially those with larger diameters, offer significant advantages in applications related to water supply, drainage, and wastewater treatment industries.

The MFE600 Electromagnetic Flow Meter is available in separate and integrated types to accommodate site-specific requirements for measuring or drilling well wastewater.

MFE600 Electromagnetic Flow Meter

The instrument has the advantages of simple and reliable construction, with no movable parts, and long service life.

• There is no flow blocking or resisting components, hence no pressure loss or fluid blocking will occur.

• There is no mechanical inertia. With a quick response and good stability, it is applicable for automatic testing, adjusting, and program control systems.

• The measuring accuracy will not be affected by the media and their physical properties like temperature, viscosity, density, and pressure, etc.

• Using PTFE, rubber, PU lining and Hc, Hb, 316L, Ti electrodes, it is applicable for different media.

• Various wastewater measuring methods like pipe-type and plug-in-type are applied in the chemical industry.

• The EEPROM storage unit is applied for safely storing and maintaining of the measured data.

• Integrated and separate types are available.
