Measuring the percentage of water in crude oil (BS&W) is an important need in many applications throughout the production and transportation process. It is particularly important in marine and truck custody transfer applications where small inaccuracies can equate to large financial loss... Traditional methods for both site and laboratory measurement include centrifuge and distillation measurement. However, these methods are slow (between 30 minutes and several hours) and prone to inaccuracies. A company in Houston, Texas called KAM CONTROLS pioneered the usage of Karl Fischer titration to detect moisture in crude oils... In 1993, a joint standard (API MPMS Chapter 10.9, ASTM D4928, ISO 12937, IP 386) was issued for measuring water in crude oil by coulometric Karl Fischer titration. This method is considerably faster (less than 5 minutes) and more accurate (up to 10 times more accurate than centrifuge and 5 times more accurate than distillation).
