The oil and gas industry is taking a renewed approach to tackling its water management challenges. Produced water streams must often be treated prior to disposal, reinjection, or reuse. These streams, found at onshore drilling sites, offshore production platforms and salt water disposal wells, are generally high in salt content, and typically, have required large filter systems comprised of exotic metals (viz., super duplex stainless steel). The capital and operating costs associated with most conventional treatment systems can be very high.
The need for economic management of produced water is critical.
HRT® affords proven solids controls and hydrocarbon recovery performance while eliminating the need for expensive excess processing, chemical additives, and storage tank capacity. With hydrocarbon recovery efficiencies of 99.98%, HRT® produces a sellable product, balancing or even outweighing operating costs and capital investment.
Clients using HRT® on produced water systems have experienced operational, environmental and economic benefits, including:
- Operational flexibility
- Reduction of lost energy
- Savings on chemical additives
- Lower maintenance costs associated with fouling
- Elimination of excursions
Why is HRT® better than conventional solutions?
Most produced water systems experience either periodic or continuous hydrocarbon and/or solids upsets, leading to:
- diminished capacity
- loss of valuable product
- damage to disposal wells and other equipment
- harm to producing formations
- and in extreme cases, shut down due to environmental emissions.
Residence tanks are ineffective at separating emulsified hydrocarbon from aqueous streams, allowing essentially all dispersed hydrocarbon to pass through.
Likewise, hydrocyclones, walnut shell filters, or induced gas/dissolved air flotation (IGF or DAF) are limited to applications with less than 200-300 ppm oil and under the best of circumstances are typically 90% - 95% effective.
HRT® was developed to remove solids as fine as ½ micron to 99.98% efficiency if desired. It will intercept and recover even stable emulsified hydrocarbons, allowing essentially zero free hydrocarbons to pass through. Consequently, HRT® provides vast improvements in the treated water quality.
HRT’s robust design is scalable and modular for both new capital projects as well as placement in existing operating units. Each system is designed to address the specific operational constraints of the application.
HRT® assists in maintaining a balanced system which provides:
- higher process reliability
- energy efficiency
- reduced potential for emissions
- reduced product loss
- significantly reduced system maintenance
