Droplet Break-up in Valves and Pumps
Understanding the effects that different levels of shear have on the separation of oil and water is vital when designing an efficient and compact production and processing facility.
The location and type of valves and pumps used in the processing facility have a direct impact on the separation efficiency and profitability. Utilizing low shear technologies reduces the number and size of the separation stages required, and reduces the need for heating and chemicals.
Removing high intensity shear zones by using low shear alternatives, and applying technologies that cause droplet coalescence, has a direct impact on CAPEX and OPEX.
What is droplet shearing and why is it important?
Low droplet shearing is important for optimizing the downstream separation efficiency.
The droplet shearing is related to turbulence in pipes and equipment. A good way of illustrating high and low shear is by shaking two bottles, where one is shaken intensely and the other lightly. The lightly shaken bottle illustrates a low shear flow regime, where the droplets remain large and separate easily in downstream separation equipment.
Droplet shearing and coalescence
In Typhonix coalescing valves and pumps, the concept of low shear is taken a step further, where the turbulence is used in a constructive way to form larger droplets.
These technologies are designed with an optimal turbulence intensity. This optimal level of turbulence is large enough to bring droplets and promote coalescence, while at the same time maintaining the large droplets.
Which low shear technologies are available?
Typhonix low shear valves, low shear pumps and coalescing pumps are available today, and have been adapted by several of the major companies all over the world. The equipment is tailored for each specific application, offering the best possible low shear performance.
