Module 01 · LP Optimizer
LP Optimization, Connected to the Model
Native LP engine directly coupled to the process simulator. Yield vectors and quality correlations flow automatically from the model — eliminating the manual LP coefficient update gap that plagues every traditional planning workflow.
01.1 · Overview
Refinium Plan
Refinium Plan is the planning module of the Refinium platform. It runs LP optimization for crude slate selection and product mix the way it should be done — with coefficients sourced live from a calibrated process simulator instead of stale, hand-maintained spreadsheets. And because Plan is integrated with Refinium Finance, every plan automatically carries its full economic context: margin, contribution, sensitivity, and confidence.
01.2 · Why It Matters
Key Capabilities at a Glance
01
No More Stale LP Coefficients
Every yield vector and quality correlation is regenerated from the live process model. When the simulator updates, the LP updates. Automatically.
02
Plan with Real Economics
Plan calls Refinium Finance behind the scenes to attach margin, cost, and sensitivity data to every scenario — so planners see both the operational and the financial answer in one run.
03
Crude Slate Optimization
Evaluate opportunity crudes, blend ratios, and seasonal slate adjustments against current product demand and pricing — with full downstream constraint visibility.
04
Product Mix & Yield Vectors
Solve for the optimal product mix given specs, blending limits, and current pricing. LP yield vectors are sourced from the simulator, not approximated.
05
Full Constraint Visibility
Hydrogen network, sulfur balance, FCC capacity, hydrotreater capacity, blending pool limits — all enforced as live constraints in the LP.
06
Multi-Period Planning
Run weekly, monthly, and rolling-quarter plans with consistent model lineage. Compare scenarios side by side with full economic context.

01.4 · Use Cases
Refinium Plan in Action
Scenario
Should we process this lower-cost opportunity crude?
A planner identifies a crude priced $3/bbl below the current slate. Plan runs the optimization with live yield vectors from the simulator, calls Finance to attach margin and sensitivity, and delivers the complete answer — yield changes, hydrogen impact, sulfur load, blend quality, and net margin delta — in one run.
Scenario
What product mix maximizes margin next month?
Given forecast demand, contract obligations, and forward product prices, Plan solves for the optimal product slate. Constraints from the simulator (FCC capacity, blending pool limits, hydrogen availability) are enforced automatically.
Scenario
How do we update the LP after a process change?
After a unit modification or catalyst change, the simulator is recalibrated. Plan automatically picks up the new yield vectors and quality correlations — no manual LP coefficient update required.
01.5 · Integrated Platform
How Refinium Plan Connects
Refinium Plan is part of the integrated Refinium platform. Every module shares the same continuously calibrated refinery model.
Refinium Finance
Plan calls Finance to attach margin, contribution, and sensitivity to every scenario.
Refinium Process
LP yield vectors and quality correlations flow live from the Process simulator.
Refinium Twin
When Twin updates the calibrated model, Plan automatically refreshes its coefficients.
Refinium RTO
Plan establishes the daily target; RTO drives the plant toward it in real time.
