Due to the gently curved nature of the vane surfaces and diffuser-type area changes within our proprietary ZP-Vane Type Inlet Device, the flow velocity reduces steadily from inlet to outlet; in turn, this lessens the potential for droplet shatter.
The ZP-Vane Type Inlet Device distributes the fluids evenly across the separator, to minimise mal-distribution effects which may lead to excessive liquid carryover in the demisting device, caused by a combination of localised elevated gas velocity levels and high liquid loading at the inlet face of the demisting device. Uniformity of the flow will also minimise any re-entrainment from the liquid surface, and minimise flow control problems.
Advantages of the ZP-Vane Type Inlet Device:
- Separates the bulk liquids present within the inlet stream
- Reduces the momentum of the inlet stream, thus minimising the potential for droplet shatter
- Distributes the gas flow evenly over the downstream demisting equipment
- Minimises the effect of channelling through the downstream demisting equipment
- Wide operational range – typically, providing 100% turndown
- Reduces the likelihood of re-entrainment of liquid from the liquid surface
- Reduces any turbulence and re-circulation within the liquid section
- Provides a minimal pressure drop
- Reduces the size of the inlet nozzle on a new build project
- Allows a greater fluid throughput for a set nozzle size on a revamp project
- Easy to install in new and existing separators
- No moving parts, thus no maintenance.
Applications of the ZP-Vane Type Inlet Device:
- Gas Scrubbers
- Production Separators
- Gas Knock-Out Drums
- Distillation, Absorption & GDU Columns
- Flare Knock-Out Drums
- Floating Production Units (FPUs).
