Oil Assay - Methanol Analysis

Methanol in crude oil impacts water treatment systems in refineries because bacteria involved in cleansing the water preferentially break down methanol, leaving hydrocarbons and toxins untreated. Methanol is miscible in water, so is present in the desalter effluent. Refineries often choose to cut crude runs rather than risk a "bug kill" - a large upset that would require major remediation and could cause violation of environmental legislation, permit excursions or future penalties.

The current analytical GC method for crude assays, ASTM D7059, requires a specialist operator and has a run time of 30-45 mins. Online NMR and NIR have detection limits of percent levels.
