About This Presentation

Slide 1 - EVALUATION OF PROGRESSIVE DISTILLATION Dan Dobesh – Jesse Sandlin Dr. Miguel Bagajewicz 04.29.2008
Slide 2 - This presentation is not about this Insurance Company
Slide 3 - Not about this one either…
Slide 4 - Our Mission “Analyze progressive crude fractionation, a technology patented in 1987 that claims to be more energy efficient than conventional fractionaltion.”
Slide 5 - Punchline “Progressive Distillation can reduce the heat duty requirement of the distillation process by 17% for a heavy crude, and use 16% less furnace heat utility while producing more valuable products for a light crude.”
Slide 6 - Overview Background: Distillation Specifications Conventional Crude Distillation Progressive Crude Distillation Methodology Results Accuracy & Limitations

Slide 8 - Oil Refinery Schematic Over 2% of the energy content in a crude stream is used in distillation.* Distillation accounts for about 40% of energy use in a refinery.** * Bagajewicz, Miguel and Ji, Shuncheng. “Rigorous Procedure for the Design of Conventional Atmospheric Crude Fractionation Units.

Slide 10 - Light Crude Feed Petroleum crude component boiling points range from -161 C (CH3) to over 827 C (C40H82+)
Slide 11 - Heavy Crude Feed Petroleum crude component boiling points range from -161 C (CH3) to over 827 C (C40H82+)
Slide 12 - ASTM D86-07b, “D86 Point” American Society for Testing and Materials (ASTM): international organization that is a source for technical standards Rigorously developed method for quantitatively testing the boiling range of a petroleum product (1) Oil sample heated in glass flask using electric heater (2) Vapor is condensed and collected (3) Temperature versus amount collected is recorded Not applicable to products containing large amounts of residual

Slide 23 - Patent: Process for Distillation of Petroleum by Progressive Separations This is an expired patent for crude fractionation that is now being commercialized by Technip. Main idea is to heat components only as much as necessary. Several companies are excited by this concept that promises large energy savings. A new refinery is being built in central Germany using this concept.

Slide 34 - Simulation Development Method Build PRO/II progressive crude simulation Obtain correct D86 95% points Synchronize product gaps Mimimize heat duty Compare to conventional heat duty Determine areas for improvement
Slide 35 - Simulation Assumptions SRK is a valid thermodynamic model for hydrocarbon systems Pseudocomponents represent crude composition PRO/II provides a close representation of reality
Slide 36 - Basis of Comparison PRO/II Conventional Simulation, 260 ⁰C steam
Slide 37 - PRO/II Computer Model(s) Progressive Model – 4 column direct Furnace heat duty = 89 MW This is higher than 58.7 MW for conventional distillation Previous work suggested that this setup provided no furnace heat utility benefit over conventional distillation. Our results verify this.
Slide 38 - Initial Complex Simulation Unnecessarily complicated Too many products for conventional comparison
Slide 39 - PRO/II Computer Model Patent Vacuum distillation for residual product is not important for comparison
Slide 40 - Second Type Simulation Too much furnace heat utility: 200+ MW Each column has a reboiler
Slide 41 - Third Type Simulation Furnace utility is lower, but steam utility his very high All seven columns have steam input
Slide 42 - Heating Supply-Demand Temperature ⁰C F*Cp MW Demand Curve – dark line showing heat needed by system Supply boxes – heat utility able to be recovered from system Heat can be transferred down and left by second law Heat can only move right across pinch via a pumparound
