Level Measurement Solutions for Chemical Storage and Feed

The process that transforms crude oil into petroleum and other valuable commodities owes much of its effectiveness to chemicals. At every step of the refining process, chemical treatment and reactions help remove impurities, create feedstocks and improve the quality of byproducts. Chemicals such as sulfuric and hydrochloric acid, sodium hydroxide, liquid catalysts, blending additives and water treatment chemicals are essential to a refinery’s day-to-day operation.

From acids to water treatment additives, a wide array of chemicals are stored at a refinery in vessels that range in size from plastic totes to large steel tanks. As with all chemical storage, there is significant risk to employees and equipment if chemicals are not secured and stored properly. This is especially true in a petroleum refining plant, which has a variety of hazardous process conditions that could be intensified through improper chemical interaction.

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

Liquid solution storage and day tanks require stringent level monitoring to ensure ongoing chemical processing. The nature of the chemical, the geometry of the holding vessel, and the presence of mixers or other hardware will determine the most suitable level technology for the chemical storage or feed application. In addition, level instrumentation must be able to withstand corrosive chemicals and deliver precise, reliable measurement to prevent accidents and spills.
