Key Responsibilities and Required Skills for a Refinery Specialist

🎯 Role Definition

A Refinery Specialist is a senior technical authority responsible for a specific process unit or a set of related units within an oil refinery (e.g., Crude Distillation Unit, Fluid Catalytic Cracker, Hydrocracker, Alkylation Unit). This individual serves as the primary subject matter expert, providing in-depth engineering support and strategic oversight to the Operations, Maintenance, and Management teams. The core purpose of the role is to drive continuous improvement by optimizing unit performance, troubleshooting complex operational issues, and ensuring long-term reliability and profitability while upholding the highest standards of safety and environmental compliance. This is a hands-on, deeply analytical position that bridges the gap between daily operations and long-term engineering strategy.

Core Responsibilities

Primary Functions

Monitor, analyze, and optimize key process variables and unit performance on a daily basis to maximize yield, efficiency, and product quality against the production plan.
Provide expert-level technical troubleshooting and guidance to the Operations team to resolve process upsets, equipment malfunctions, and operational deviations in a timely and safe manner.
Lead or actively participate in Root Cause Analysis (RCA) investigations for safety incidents, environmental events, and significant production losses to identify underlying causes and implement effective corrective actions.
Develop, propose, and implement process improvement projects, including debottlenecking studies and technology upgrades, to enhance unit reliability, increase throughput, and reduce operating costs.
Act as the technical lead for the assigned unit during planned shutdowns, turnarounds, and startups, providing detailed engineering oversight and support for critical activities.
Create, review, and maintain critical operating procedures, standard operating conditions (SOCs), and process safety information to ensure they are accurate, effective, and compliant.
Manage the unit's catalyst and chemical programs, working closely with suppliers to monitor performance, optimize usage, and plan for catalyst change-outs.
Develop and utilize process simulation models (e.g., HYSYS, Pro/II) to evaluate process changes, test optimization hypotheses, and support MOC and PHA activities.
Serve as the technical authority for the Management of Change (MOC) process, rigorously reviewing proposed changes to ensure they are safe, well-engineered, and properly documented.
Conduct regular performance testing and health monitoring of critical equipment (e.g., reactors, columns, heat exchangers) to proactively identify potential issues and degradation.
Mentor, coach, and develop junior engineers and operations personnel, transferring critical knowledge and fostering technical excellence within the team.
Ensure the unit operates in strict compliance with all local, state, and federal environmental, health, and safety (EHS) regulations and internal company standards.
Prepare and present detailed technical reports, performance summaries, and project justifications to various levels of management.
Lead and facilitate Process Hazard Analyses (PHAs), such as HAZOP studies, for new projects and existing unit revalidations.
Collaborate with the Economics & Planning department to provide technical input for feedstock selection, production planning, and refinery-wide optimization models.
Evaluate emerging technologies, industry best practices, and innovative solutions, and assess their potential for application within the assigned process area.
Develop and track key performance indicators (KPIs) for the unit, providing regular analysis on trends, performance gaps, and improvement initiatives.
Serve as the primary technical point of contact for capital projects affecting the assigned unit, from conceptual design through to commissioning and startup.
Support the maintenance and reliability teams by providing process engineering expertise for equipment strategy development and failure analysis.
Participate in the site's emergency response organization, providing critical technical expertise during plant emergencies.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis to investigate complex performance trends or validate operational hypotheses.
Contribute to the organization's long-term technology and digitalization strategy and roadmap.
Collaborate with business units, such as Commercial and Supply Chain, to translate market needs and opportunities into engineering requirements.
Engage in industry forums, technical committees, and professional conferences to stay abreast of emerging trends and maintain a strong professional network.

Required Skills & Competencies
