A tank was vented via a lute pot arrangement. The lute pot was originally filled with low viscosity mineral oil but due to a misunderstanding was topped up with water. The water froze in the bottom of the lute thus sealing the main vent line and the tank roof seam ruptured when liquid was pumped in. GENERAL RELIEF DESIGN PHILOSOPHY
Thus, a relief device is required. Typical pressure relief devices are either lute pots or pV Valves. Lutes have generally fallen out of favour because of the inherent problems of maintaining the liquid seal and the attendant pollution problems. See diagram .

It is usual to use an inert gas pad in combination with either a Pressure/Vacuum Valve (PVV) or lute pot system to prevent unrestricted losses of the pad gas. The padding system is set to maintain the tank pressure between the pressure and …

2014年11月20日 · If you can make the lute / pot deep enough so that it always has more liquid column than your max gas pressure even when empty then you should be able to say it will never vent. However if you can't do that then then you could have gas blow by.

Lute (material) - Wikipedia
In pottery, luting is a technique for joining pieces of unfired leather-hard clay together, using a wet clay slip or slurry as adhesive. The complete object is then fired. Large objects are often built up in this way, for example the figures of the Terracotta Army in ancient China.

The importance of seal pot level measurement
2018年9月24日 · Seal pot with with top-mounted guided wave radar transmitter. In terms of level measurement, seal pots have a site glass level gauge or magnetic level indicator (MLI) for local viewing. However, automation is necessary to provide alarm capabilities for the sealing system.

2024年11月24日 · A U-shaped loop in a pipe or tube in which a liquid is trapped and used to provide a seal for gas flow. For example, the pipe from a gravity-fed reflux from the condenser of a distillation column contains a lute. The distillation column has a higher pressure than the condenser and the lute prevents vapour entering from the wrong direction.
