Part One of this paper (HE, March 2018, pp 101-108) discussed a methodology developed by the authors of this article series to benchmark a refinery’s fuel blending system. This methodology produces two indices, automation effectiveness, and operational efficiency, to assess the refinery’s blending infrastructure and execution practices. This methodology also creates a comparative ranking compared to other refineries’ blending systems.
It also gives a qualitative and quantitative criterion for the required investment to upgrade their fuel blending system to bring to par with other refineries in the world and to capture the lost benefits due to the sub-optimum blending system at the refinery. This part two of the series discusses how this methodology is executed by presenting the phased process in a case study for a 300KB/day refinery in south Texas, USA.
The refinery retained the services of the authors of this paper to assess the current state of their fuel blending and recommend the steps to upgrade/revamp their blending system, if found feasible, both technically and economically. An abridged version of this paper is published in “Bench-marking Fuel Blending Systems, Part-Two,” Hydrocarbon Engineering, March 2018, pp 67-72
