Oil and Gas Removal with Electro Water Separation

Electro Water Separation (EWS)

OriginClear’s proprietary Electro Water Separation™ (EWS) technology is particularly effective in the treatment of produced and frack flowback water from the oil & gas market.

EWS is a continuous, chemical-free, low-energy oil gas water separator process. Exhaustive testing has indicated that Specific Energy Consumption averages 5.1 kWh/kgal of processed water. Assuming an energy cost of $0.15 per kWh, the energy cost of operating the EWS technology is estimated at $0.03 per barrel of water treated.

An Oil Gas Water Separator

The EWS process efficiently removes non-soluble organics and inorganics, such as free & dispersed oil and suspended solids, through sequential stages of electro-coagulation and electro-flotation.

The electro-coagulation process breaks the oil/water emulsion and causes the oil and suspended particles to coagulate into larger particles. EWS targets the one to twenty-five-micron size oil droplets and suspended particles for coagulation and flotation that is too time intensive to remove with standard gravity-based separation technologies.

Electro-flotation creates a high-density concentration of micron size bubbles which lift the coagulated particles to the surface for separation. The result is a better-pretreated water, to enable high-quality downstream processes that would not have been possible with conventional pretreatment.

In addition, the EWS technology platform offers a third, synergistic function of electro-oxidation, which is effective in removing bacteria, and certain ions that are capable of being precipitated from solution. The electro-oxidation stage has shown value when used as a stand-alone equipment for water and wastewater treatment.

Electro-Oxidation (EO) Toolkit

Now available, the electro-oxidation stage can be used singularly to effectively treat produced water for bacteria and hydrogen sulfide (H2S), without requiring chemicals. The process is also very energy efficient.

Recent field testing within the Eagle Ford formation in South Texas showed biological activity was reduced by 96%, and hydrogen sulfide (H2S) reduced by 97%. (See Application Note.)

OriginClear’s EO Toolkit is available for licensing and to end-users interested in showcase applications. Contact us now.

How Is EWS Different?

The designs incorporated in EWS technology are unlike other electro-coagulation (EC) systems tried over the years.

Other EC Approaches

Earlier EC generations have historically used heavy plates as the anode and cathode, with wide gap separation. The wide separation requires high power to achieve the dosage rates required for effective coagulation.

Typical EC systems have been stand-alone systems with separate pieces of equipment for gravity separation and disinfection. EWS integrates these functions into one stand-alone piece of equipment with SCADA control over all three technologies.

Our EC Approach

Instead, the EWS electro-coagulation reactors use an outer tube and an inner rod as the cathode and anode with the water flowing through the annular space.

The resultant narrow annular gap and high mass transfer rate minimizes the power necessary to achieve effective coagulation. The high mass transfer rates also inhibit scaling and anode passivation.

As a result of the above designs, the EWS EC reactors require far less power with an estimated Selective Energy Consumption of 0.28kWh per barrel of water.

Less anode consumption is seen, and the anodes are far easier to replace and maintain.

Our Electro-Flotation Approach

EWS electro-flotation technology utilizes non-donating anodes and cathodes to generate micro-bubbles over the complete volume of water in the flotation chamber. These microbubbles are small enough to embed or attach themselves to the coalesced oil and suspended solid particles.

The flotation chamber itself is also specifically designed to separate a larger percentage of the oil and solids, leaving progressively clearer water.

Licensing

Equipment suppliers who have technology that would benefit from EWS’s pretreatment technology, and system integrators who want to utilize EWS’s pretreatment technology, can license EWS on a private label basis.

SCADA Controls

EWS systems have been designed to include a common SCADA control system with touch screen which will allow automatic control of the process as well as remote monitoring and alarms.

The Results

In The Field

EWS has been successfully tested in a wide range of produced and frac flowback waters in the gas fields of Western Colorado, West Texas intermediate oil fields and the San Joaquin heavy oil fields of California.

Each of these waters has been unique, but EWS technology has proven flexible and robust enough to handle these widely varying challenges within the oil and gas industry.

In San Joaquin, third party lab results confirmed that EWS reduced all measures of treated water's non-soluble contamination to very low, or undetectable levels.

The client, a regional water treatment entity, commissioned the 60-day test, which began in July, 2016. View or download the report here.
