Venturi Jet (Atomizer)-Type Burner for Determining Sulfur in Light Petroleum Products

Abstract

ASTM procedure for determining Jsmall percentages of sulfur (1 to 10 p.p.m.) in light petroleum products is not completely suitable, mainly because sufficient sample for accurate measurement cannot be burned in a reasonable time. Work in this laboratory resulted in the development of a better burner, shown in Figure 1, in which air or carbon dioxide-oxygen mixtures may be used to produce a blue Bunsen burner type of flame. It burns approximately 60.0 grams of fuel per hour; a similar type 2.0 mm. greater in diameter burned fuel iy2 times as fast. Highly aromatic materials such as benzene are completely burned. Figure 2 shows the assembly in which the burner is used.Determination of Operating Conditions.Remove the re-igniter-grid assembly and mount the burner in a vertical position with the fuel stopcock closed.
