ABLE Nucleonics picked for Level Measurement on Suncor HANZE F2A Platform

Suncor (formerly Petro-Canada) has recently installed a new desander skid for their gas well on the Hanze Platform, in the Dutch sector of the North Sea, approx 200 km North-West of Den Helder. Suncor has already utilised the ABLE Nucleonic equipment on another platform and therefore specified the same equipment for Hanze, maintaining continuity. The desander skid duty is to prevent sand being carried over in to the process lines. On the Hanze gas well, the gas flow comes in to the desander vessel and any sand entrained in the flow would fall out of the flow and fill up the desander vessel. The nucleonic level detector has been installed as a high level trip/alarm on this vessel.
Fast flowing gas with entrained sand results in a highly abrasive medium, so the life expectancy of any level instruments which require exposure to the medium would be severely limited due to the harsh nature of the process.
The ABLE nucleonic system gives a non-contact measurement, which not only reduces potential leak paths, but is also unaffected by the abrasive process in the vessel. It is also extremely useful on a gas well where vessels often run at high pressures.
The measurement is extremely important to the process as any carry over of sand to the downstream equipment in a gas plant, which is expecting low density material devoid of solids, could be fatal for the instrumentation. Sand carry over can damage valves, valve seals and, if carried over into the compressors, can cause catastrophic failures.
The point level trip will provide a reliable indication of the amount of sand in the desander allowing it to be removed well in advance of carry over, thus preventing any potential damage. This also reduces down time and maintenance of the downstream equipment.
