Level Measurement Solutions for Sulfur Pits

Elemental molten sulfur is removed as a by-product of desulfurization process in refineries. The collection tanks must be kept hot in order the keep the sulfur fluid. Semi-molten solid is kept hot and well insulated. The sulfur vapors can be heavy and will condense in cooler areas, so the challenge is to minimize the condensation. Use Rosemount 5408 with cone antenna or process seal antenna. If mounted on a nozzle, the nozzle should be well insulated, and heat traced to reduce sulfur condensation. Insulate and heat-trace the nozzle to reduce the amount of build-up. If possible tall nozzles should be avoided. A Rosemount 5408 with parabolic antenna may also be used. The antenna should be inside the vessel. This will minimize potential crystallization or build-up. Signal quality metrics may be used to monitor signal strength to determine if cleaning of antenna or probe is needed.
