Product Description

Vane Type Demister Introduction
The DynaVane^TM style of mist eliminators is a sophisticated assembly of expertly engineered vanes. These vanes are designed to deftly separate liquid droplets from a vapor stream through inertial impaction as droplets collide with the vane surfaces. During this process, the gas skillfully navigates a zigzag pathway between the vanes, ensuring optimal separation. Over time, several foundational styles have emerged, setting the industry standard for various specialized applications.

Rhine Ruhr proudly designs and manufactures the following standard DynaVane^TM styles:

1. The VC single pocket range, featuring chevron vanes without drainage channels, provides a streamlined solution.
2. The VDC double pocket range is intelligently designed with enclosed drainage channels for superior efficiency.
3. The HC single pocket range offers open drainage for effective liquid removal.
4. The HDC double pocket range boasts enclosed drainage channels, enhancing overall functionality.

 

Droplet Removal Efficiency:
The level of droplet removal for any specific droplet size can be accurately calculated using centrifugal forces and Stokes Law. Rhine Ruhr has developed advanced computer models to estimate droplet removal efficiencies, allowing for the precise optimization of vane geometry tailored to any specific duty.
The liquid removal efficiency of DynaVane^TM series is an impressive 99.9% for droplets ranging from 10µ⁺ to 30µ⁺
In general, droplet removal efficiency is enhanced with the following conditions:

1. Increasing Gas Velocity, which propels droplets more forcefully against the vanes.
2. Increasing Gas and Liquid density difference, promoting a more substantial separation.
3. Decreasing Gas Viscosity, allowing droplets to more readily be captured.
4. Increase Vane Angle, optimizing the impact and capture rate.
5. Decreasing Vane Pitch, improving the thoroughness of separation.

Mechanical Design:
DynaVane^TM Mist Eliminators are meticulously custom-manufactured to seamlessly integrate with the specific vessel arrangements required. The installation, whether comprising loose segments supported by annular rings and/or beams secured with retainer bars, or vane packs designed for integration with a sealed gas box, is engineered for both efficacy and ease.

1. Loose segments supported on annular rings and/or beams secured with either retainer bars.
2. Vane Packs designed for fixing to a sealed gas box.

In each scenario, the complete assembly is thoughtfully designed and supplied in sections, each crafted to fit through access manways for manageable installation within the vessel.
While every component is constructed from lightweight materials to facilitate installation and assembly, the overall build is robust enough to endure a wide range of service conditions, including vibrations and slugging, within a suitably designed and sized vessel arrangement.

Note: Actual droplet removal size range will vary according to system properties. Mechanical Design: DynaVane^TM  Mist  Eliminators  are  custom  manufactured  to  be compatible  with  the  required  vessel  arrangement.  Installation can be either:- ·     Loose   segments   supported   on   annular   rings   and/or beams secured with either retainer bars. ·     Vane Packs designed for fixing to a sealed gas box. In each case, the complete assembly is designed and supplied in sections which are sized to fit through access manways and are able to be man handled inside the vessel. Vane  Packs  consist  of  DynaVane^TM  elements  fully  enclosed  in housings  with  built  in  drainage  sump.  Although  all  parts  are constructed from lightweight material to assist installation and assembly,   the   overall   construction   is   sufficiently   robust   to withstand   most   service   conditions   including   vibration   and slugging in a suitably designed and sized vessel arrangement.
