Requisition ID: 66481
This job is part of a team that uses complex mathematical models of petroleum refineries (called “linear programs”) as well as economic pricing and product-demand forecasts to select raw materials and to determine the optimal product mix for a crude oil refinery and its associated geographic region. The job focuses specifically on review and improvement of the models of catalytic processes. The application of catalysts is the most prevalent type of technology used to change the chemical composition of oil in a refinery, as catalysts directly affect product yield, relative crude value, and cost of production. The job also provides engineering advice on processing techniques or operating changes to improve refinery efficiency, increase yield of higher valued products, and expand the range of raw material options. This includes analyzing and preparing for major maintenance projects (“turnarounds”) as well as designing operating changes to remove identified limitations or to realize increased performance, and working with the maintenance team to implement the changes during turnarounds.
- Provides technical support for developing and updating the individual “unit models” in the regional refining Linear Programs (“LP”) computer software models for all Andeavor refineries. Works with other Business Optimization Advisors (“BOAs”), the Refining Linear Programming Technology group, the refining technology subject matter experts, and refinery operations and process engineering teams to conduct test runs, evaluate catalyst performance and unit yields, and improve the accuracy of the individual unit models in the LP. Uses mathematical modeling of the catalysts (i.e., unit kinetic models) to evaluate the economics of different raw materials (input oils or feed streams) and different operating modes, including inputs sources from other Andeavor refineries and third party sources purchased in the global market. Uses the regional refinery LPs to identify opportunities for commercial value improvement. Leverages multi-refinery technical and operating experience to work with the refinery engineering and operating teams to implement operating changes. Works with the regional refinery economics and planning teams to identify and resolve yield deficiencies in the Aspen Petroleum Scheduling (APS) software. APS serves a critical function for the regional refinery planning teams as the platform used to plan detailed refinery operation and to develop and communicate the projected charge and yield to Scheduling and Trading groups. Provides back-fill for the BOAs in other assigned regions, as needed. Works with and supports the Supply Coordinators, as needed; provides back-fill as needed and available.
- Bachelor of Science in Chemical Engineering or Mechanical Engineering required
- College-level course work in chemical reaction kinetics and in catalysis including preparation, characterization, and structure modifications required
Minimum of 6 years of petroleum refining work experience, with assignments in at least two different full conversion refineries (full conversion includes coking, fluidized catalytic cracking, hydrocracking, and gas oil hydrotreating) is required. Minimum of 5 years (inclusive) of Operations Support Engineering experience on multiple refinery units—including high-pressure hydroprocessing—is required. OSE experience to include leading turnaround technical support, including supervising full unit catalyst changes on at least each of the following types of units: naphtha hydrotreating, distillate hydrotreating, high pressure (greater than 1500 psig) gas oil hydrotreating, and hydrocracking. Minimum of 1 year (inclusive) of Operations Supervision experience in hydrocracking and distillate hydroprocessing is required. OSE responsibilities in this role must have included the following: driving optimization and coordinating cross-functional teams to implement process and/or procedural change. Minimum of 1 year (inclusive) of experience analyzing pilot plant test results for hydrocarbon processing catalysts to support catalyst selection for commercial high pressure hytrotreating units is required.
- Experience is required in at least three projects on specific types of refining processes that improved throughput and on-stream factor. During these projects, specific focus on changing catalyst loading plan in existing reactor vessels and on identifying and resolving deficiencies in existing heat recovery and fired heater equipment during unit shutdowns for maintenance (turnarounds) versus installation of new or larger equipment is required.
- Domestic travel up to 25% of the time required.
