When to apply a low shear valve

There are a number of reasons to apply the low shear Typhoon Valve System:

1. Improve downstream separation

Shear in control or choke valves reduces the efficiency of downstream separation equipment, like 2- or 3-phase separators and produced water treatment equipment. Replacing the choke or control valve with a Typhoon Valve System improves separation efficiency.

2. Debottleneck separation systems or produced water treatment systems

The enhanced separation efficiency obtained with the use of the Typhoon Valve System requires less retention time in separators, settling tanks and flotation units enabling increased production / flow rates. This is a very cost efficient way to debottleneck the separation system as no additional new equipment or expensive modifications to the separator internals are required.

3. Reduce energy or chemical consumption

The larger droplets in the outlet stream of the Typhoon Valve System reduces the emulsification of liquids enabling the separation of oil and water at lower temperatures or with less chemicals.

4. Improve the Environmental Impact Factor (EIF) of your process

All above arguments have a positive effect on your EIF. Implementation of Typhoon Valve System is a simple and efficient solution to improve oil-water separation and achieve compliance to corporate goals for sustainable energy production in an environmentally sound manner.

5. Improve system robustness

The mechanical solution incorporated in the Typhoon Valve System to reduce shear forces exerted on the fluid improves the overall robustness of the separation system to upsets and changes in the production profile.

6. Longer life of mature fields

Water production in excess of the capacity of the produced water treatment facility may reduce overall production capacity. Especially in mature fields this can be a major bottleneck in production capacity. Typhoon Valve System provides a more efficient handling of the produced water and contributes to a longer production lifetime of the field.

Where to Apply Typhoon Valve System

In general, the further upstream a low shear Typhoon Valve System is used, the higher the potential. Prime targets for use of the Typhoon Valve System are therefore oil production choke valves and separator level control valves.

It is important to realize that the creation of emulsions normally does not require a high pressure drop (ref. doc.  SPE 18204 and SPE 56643). Significant improved separation with Typhoon Valve System compared to conventional valves has already be tested down to 1 bar (14,5 psi) pressure drop. 

Recorded improvements in OiW are as high as 40-60% in comparison to conventional valves, as demonstrated in the successful offshore installation of Typhoon® System on Statoil’s Troll C.

For produced water applications, pressure drop, inlet droplet size and oil concentration are more important. Recorded improvement in OiW are as high as 20-25% in comparison to conventional valves, as presented in this business case about meeting environmental targets with a low shear Typhoon Valve System.
