Abstract:
Water in petrochemical and refinery streams can cause problems for processors. Freezing of pipe lines and valves and also poisoning of expensive catalysts are just a few examples. Monitoring water in petroleum from an upstream source to the downstream processing plant is critical to insure uninterrupted operation. Unlike the Karl Fischer analysis, the GC water analyzer does not suffer from the adverse effects of the petroleum matrix which can skew the KF results. GC methods can bypass the undesirable chemical interference that would otherwise be present like “Sulfur interaction” and acetone. The use of the LUMA™ VUV detector and Supelco’s water analysis column “Watercol” are combined to separate and measure the water in a propane, propylene and butane streams. The VUV LUMA detector provides sensitive and accurate results using hydrogen as carrier gas. Measurements can be made down to water levels of less than 1 ppm.
