SmartProcess® Fractionator
Oil fractionator columns are often highly constrained, with significant controller interactions and long time constants. Advanced Process Control (APC) is an ideal method for optimizing fractionator performance. Emerson's SmartProcess® Fractionator Optimizer takes the effort of implementing APC on these units to a new level of ease and cost effectiveness.

Even smallcapacity units can capture the benefits of APC that larger refiners have been enjoying for years:
- 3-5% higher throughput
- 30-80% reduction in product quality variability
- 2-5% improvement in distillate yields
- 2-5% reduction in energy costs
Emerson's industry consultants are available to assist with any stage of a Fractionator APC project. The methodology typically includes:
- Evaluation of existing plant operations and objectives
- Pre-step tests to ID preliminary dynamics & issues with regulatory control loops
- Functional Design Spec to outline how SmartProcess will be configured
- Configuration and installation
- Process step-testing where online data is analyzed
- Models developed to match observed responses
- Controller generated and tested in the off-line simulation
- Downloading tested controller to the control system
