Once natural gas is extracted and separated, it usually must be injected with chemicals before moving on to the rest of the treatment and refining process. These chemicals help prevent problems that can arise downstream and might affect production and processing.
Chemical agents employed in natural gas processing include drilling fluid additives, methanol injection for freeze protection, glycol injection for hydrate inhibition, produced water treatment chemicals, foam and corrosion inhibitors, de-emulsifiers, desalting chemicals and drag reduction agents. Chemicals are frequently administered by way of chemical injection skids.
In this blog, part of the Magnetrol® blog series on natural gas processing, we will explore level measurement solutions for chemical injection skids and mechanisms and the specific challenges that make this application difficult to measure.
Level Measurement Challenges and Considerations
Level monitoring controls chemical inventory and determines when the tanks require filling. The careful selection and application of level controls to chemical injection systems can effectively protect against tanks running out of chemicals or overfilling. Without reliable, consistent level measurement, accidents and spillage can occur.
