Electromagnetic Flowmeters for Oil Wastewater Treatment
Effective treatment of oil production wastewater pollution and the usage of wastewater resources has become a core issue for oilfield development.
The first factor in wastewater treatment is to correctly measure the wastewater produced.
Onsite challenges:
1. Oil manufacturing wastewater includes a lot of suspended solids, and the blades in the turbine flowmeter are prone to jamming and require being disassembled and maintained regularly.
2. Turbine flowmeters utilized in various pipelines and process links are not universal, and field device maintenance is difficult.
3. The 2-inch pipeline flow is less than 70 m3 / day, and the turbine flowmeter can't measure the micro-flow precisely.
4. It is simple to accumulate impurities at the lower end of the coupling device, which reduces the measurement precision, and even the small flow of some stations cannot be measured
5. The temperature of oil manufacturing wastewater is excessive and contains various salts and other impurities, which easily corrode the turbine flowmeter.
According to the actual working environment of the customer's site, the current difficulties are excessive maintenance frequency and intensive workload for single maintenance. Special electromagnetic flowmeters are designed for field use. Their traits are as follows:
1. Custom-developed circuits and software based on the field can ensure the detection of small flow rates.
2. The special structural design of the sensor resists high pressure and high temperature.
1. The measuring pipe of the electromagnetic flowmeter has a through the diameter, and there aren't any flow-blocking parts inside. It will not block and eliminate the work of everyday disassembly and maintenance.
2. The purchaser can select anti-corrosive electrodes and lining materials to ensure long-term use of the device.
3. The communication software and communication interface are changed based on the purchaser’s requirements, and compatible with the purchaser’s current system, decreasing the price of changing the tool.
Some sites in the oil field can't fulfill the installation needs of 5D in front of the flow meter and 3D behind it (D is the inner diameter of the chosen device) in the straight pipe sections.
The electromagnetic flowmeter can be used to ensure stable performance in the field. The metering process is stable and reliable.
