Production planning

Crude Slate Design™, an add-on module to Hexxcell Studio™ dedicated to oil refineries, provides a data-driven, predictive approach to evaluating the effect that the selection of oils have on fouling behaviour on the crude distillation unit.

Problem
Oil blending in oil refineries defines not just production yields but also fouling behavior in the crude pre-heat train and the atmospheric the furnace. While some guidelines for incompatibility exist, it is very difficult to predict the impact of blending decisions on the fouling behaviour together with the operating conditions, heat exchanger configuration and current state of the equipment. As a result, it is not possible to assess at the production planning stage the impact on energy consumption and CO2 emissions of the blending choices.
Crude Slate Design™
Crude Slate Design™, an add-on module to Hexxcell Studio™ dedicated to oil refineries, provides a data-driven, predictive approach to evaluating the effect that the selection of oils have on fouling behaviour on the crude distillation unit. As a result, oil planners can use this tool to assess, in a simple way and ahead of time how their blending decisions are going to impact operations (e.g. hitting furnace or hydraulic limits etc.) and to quantify the costs of processing specific slates both in economic and environmental terms. This information can also be fed back to operators and used to further optimise plant performance and maintenance actions.
Key Benefits
1.Assess crude blending decisions in advance to prevent furnace andhydraulic constraints.
2. Provide feedback for feedstock purchasing and production planning basedon KPIs:
- Processing cost
- CO2 emissionsc)Operational constraints
- Optimal blending strategy
3. Determine optimal blending strategy
