Rising prices of diesel fuel are creating a market for alternative sources. One of those sources is diesel fuel derived from vegetable oil. Diesel fuel made from plants has the potential to contain glycerols in the form of free glycerin, mono, di and tri glycerides. These compounds have been found to be detrimental to diesel engines so must be removed prior to use. This application note describes a turn-key system for the analysis and automated reporting of free and total glycerines in biodiesel fuel.
ASTM-6584 requires a two internal standard, fi ve-point calibration curve be generated for free Glycerine, Monoglycerides, Diglycerides and Triglycerides achieving a linearity of 0.99 r2. Standards are available from Chromatography supply vendors such as Supelco, Belfont, PA. The analytical standards must be derivatized from the free acid form to a methyl ester form so that they will move through a gas chromatographic column prior to analysis.
Products & Services
Power generation systems are power generators and related systems that are used in power plants or large-scale power generation facilities.
Electrical power generators transform mechanical energy into electrical energy, typically for backup or emergency power. Generators can produce either AC or DC power and are typically powered by a fuel engine.
Injection pumps are designed to inject measured amounts of fluid into a reservoir or production system.
Engines and components are used to convert energy into mechanical force and motion for automotive and industrial applications.
Trash pumps are designed to pump large amounts of water that contains hard and soft solids such as mud, leaves, twigs, sand, and sludge. Most devices are portable, heavy-duty centrifugal pumps that feature deeper impeller vanes and larger discharge openings than other pumps.
