Oily and Produced Water Treatment:

Produced water treatment for water injection or reinjection improves the recoverable reserves from a reservoir by establishing an external water drive and by maintaining reservoir pressure. This process can often double the recoverable reserve from oil production. To achieve this level of production performance, special injection water quality is required. The injection water must be free of oxygen that will cause corrosion of the injection well piping, and particles that will cause plugging of the reservoir. Oil in particular must be removed, and TSS are brought to a minimum level.

Whatever your produced water treatment needs, Extol Hydro has the experience and systems to meet your water quality requirements, enhance oil production and protect your reservoir. We have supplied water injection process systems for onshore installations and for fixed and floating facilities offshore. We are treating well water, river water, seawater and produced water for injection or reinjection.

Flue Gas Desulfurization:

One of the most commonly used FGD technologies for scrubbing pollutants from power plant gas emissions is a limestone forced oxidation (LSFO) scrubber system. In this process, many pollutants end up in the circulating water in the scrubber. To maintain appropriate operating conditions, a constant purge stream is discharged from the scrubber system, and the purge stream contains contaminants from coal, limestone, and make-up water. The purge is acidic and supersaturated with gypsum, with high concentrations of TDS, TSS, heavy metals, chlorides and occasionally, dissolved organic compounds.

Flue gas desulfurization (FGD) scrubber effluent from coal-fired power generation requires varying degrees of treatment dependent on the type of coal, water sources, and environmental regulations.

FGD purge / blowdown contains toxic constituents such as heavy metals as well as chloride and sulfate salts of calcium, magnesium, and sodium. Conventional treatment involves physical and chemical processes that remove the undesirable components to meet effluent discharge limits.

Physical, chemical, and even biological treatment methods may not be able to reduce pollutant concentrations to the part per trillion levels required for discharge of some chemical species as discharge limits become more stringent. These processes also do not address reduction of the volume of liquid effluent nor its salinity. They also do not recover water for re-use within the plant while generating large amounts of sludge which require off-site disposal.

Extol Hydro Tech provides various treatment options that offer volume reduction, recycling of valuable water, and reuse within the facility as often times water resources are extremely limited. Evaporation provides an effective alternative to standard treatment processes that allows for reclamation of process water in addition to minimizing the overall wastewater volume up to zero liquid discharge (ZLD).
