Refiners can improve the economics of their gasoline-blending operations and octane and volatility analyses by using in-line blending procedures and on-line specification analysis. The Environmental Protection agency's current lead content rules have decreased refiners' blend options to meet octane specifications, and tighter vapor pressure controls that may be imposed nationwide and in force in some areas, will restrict refiners' use of butane to control Rvp. In-line blending operations allow refiners to blend gasoline components closer to the specification, reducing the excess amount of high octane material needed to ensure proper octane level of the finished gasoline. If gasoline Rvp is restricted, refiners will want to blend as much low-cost butane without exceeding the Rvp limits. Improvements in blending and analysis equipment have decreased the relative costs and improved the performance of the equipment. And although, during the last 20 years inline blending systems have been installed in about 100 refineries in the U.S. and Canada, some of these refineries are not making full use of the economic advantages offered. Refiners that do not have in-line blending should consider making a serious evaluation even though a project may have been turned down in the past. Refiners who already have in-line blending might want to reevaluate their equipment and procedures.
