Level Measurement Solutions for Acid Settling Tanks

acid settling tank level measurement

Alkylation is a combining process that creates alkylate, a premium, high-octane blending stock. Many refineries have alkylation units in order to increase their capacity for producing valuable end products. The reactor effluent flows to a large tank within the unit, which allows for separation of the acid/hydrocarbon emulsion created in the reactor. These devices are known as acid settling tanks. acid settling tanks

Magnetrol® has produced an applications brochure for the petroleum refining industry detailing level measurement challenges and solutions for each step of the refining process. This blog post is part of an occasional series exploring each application in detail.

Level Measurement Challenges and Considerations

Interface level control of an acid settling tank is required. Product/acid cross-contamination causes overall efficiency problems and can result in hazardous conditions. Inaccurate settler level indication is a frequent cause of physical acid carryover in the reactor effluent. Release of acid can cause extreme hazards to both process and personnel.

Sight glasses have traditionally measured level in acid settling tanks, but these are susceptible to plugging and require diligent flushing at regular intervals. More reliable instrumentation is needed to ensure safety and keep the unit running efficiently.
