Zhengyuan supplies complete skid-mounted crude oil dehydration and desalting packages for offshore platforms, FPSOs and onshore facilities. Each package is configured around crude oil properties, throughput, required outlet quality and site conditions. Electrostatic coalescence helps dispersed water droplets combine and separate from crude oil. Desalting removes salts carried in the water phase, with wash-water mixing and treatment stages selected for each project. Our EPCIC services cover engineering, procurement, construction, installation and commissioning, including offshore work. We also provide training and ongoing after-sales technical support. Send your project RFQ or available operating data to discuss your requirements.

The fresh water must be exchanged with the electric desalination drainage to 80-90 ℃ and then used as the electric desalination water injection.
The injection points of water injection for electric desalination are set to 3, one injection point in front of the primary and secondary mixing systems, and a new injection point in front of the heat exchanger. The water injection volume is about 1% (if necessary). The mixed effect of the pipeline, so that the salt in the crude oil is dissolved in the water, and it acts together with the demulsifier, which is beneficial to the desalination of the crude oil.
The secondary electric desalination tank is injected with fresh water, and the secondary electric desalination drainage is used as the primary electric desalination water injection. Considering the actual operation situation, both primary and secondary lines need to have double lines that can be injected with fresh water, and secondary drainage also needs to have double lines to drain directly to the sewage pipeline outside the tank.
The two-stage electric desalination process is adopted, one tank is one stage, and the desalination process flow is shown in the following figure:
Electrostatics Ccoalescence Technology
Most advancedtechnology in the world, which belongs only to us except that Norseland has the similar technology.We work with China's top petrochemical research institute, it has spent us more than 10years for research and practical application.Norseland used this technology in 10 places in the world, we used 4places about.Appropriate working condition:high water content of crude oil with high denseness.Working effect: High efficiency dehydration.
