Sentech - Level Profiler
While DP and guided wave radar level transmitters – and even mechanical floaters and visual gauges – serve their purpose in light, sweet crudes and generally when water separates easily from oil, heavier and more viscous crude oils introduce much more complex layers and less defined levels in production separators.
With tight emulsions, long settling times and severe foaming, operators need better information to optimize separator throughput, and still avoid excess water on the oil outlet and liquid carry-over on the gas outlet.
The Sentech Level Profiler is the only technology on the market able to provide this level of detail and seamless representation of complex separator layers without any nuclear sources.
The Sentech Level Profiler employs a series of SeCaP sensors allowing operators to "see through the walls" of the separator:
- Accurate location of water, emulsion, oil, foam and free gas layers relative to top of weir plate
- Seamless gradient color for varying water cut across emulsion layer
- Customization of vertical resolution to customer requirements (1 cm resolution possible)
- Optimization of resolution at critical levels in separator (e.g. just below top of weir plate)
- Optional flushing capability for effective cleaning of sensors without affecting production
Beyond conventional production separators, other useful applications for the Sentech Level Profiler include:
- Horizontal and vertical Free Water Knockout drums/vessels
- Mechanical and electrical coalescers – to optimize process and throughput
- Heater treaters – the Sentech Level Profiler can be supplied for temperatures up to 225°C
- Storage tanks – to determine level of residual water gathered at the bottom of the tank
