fall 2015 final presentation
TRANSCRIPT
About Me
From Dublin, OhioFourth Co-op with Marathon
– Canton Fall 2013– Canton Summer 2014– Cincinnati Spring 2015
Education– Fourth year at the University of Cincinnati– Bachelor’s in Chemical Engineering– Graduate Spring of 2017
2
Goals for the Fall
My GoalsPersonal Goals
– Take on as many unit engineer responsibilities as I can
– Get the chance to learn a new unit and understand how it is integrated with the rest of the refinery
Professional Goals – Strengthen communication skills – Strengthen technical knowledge on
unit/tower design
3
Projects and Responsibilities
CFU Max Rate Test – Field data collection– Mass and Energy Balance– Post Audit Memo
Deepcut TAR – Deepcut PI Graphics
CFU/LEP FOE MetricsSpring 2015 Bundle Cleaning Program Memo
4
CFU Max Rate Test
Scope of WorkComplete CFU Max Rate test
– Assisted operations with temperature and pressure surveys around all heat exchangers and pumps
– Collected routine and non-routine samples during varying step test rates
Results Mass and Energy Balance
– CFU Charge Rate: 40 MBPD– CFU Charge Rate: 46.2 MBPD
Recommendations for future process improvement
Post-rate test memo
5
Deepcut TAR: South End
Scope of WorkInternal vessel and tower inspections
– Mechanical damage & Cleanliness FCO & PSSR Walk-downsTracking Heat Exchanger bundle cleaning & collecting samplesMic’d and verified orifice plate installationPI Graphics
– Update graphics to show new equipment and circuits
6
CFU/LEP FOE (Focused on Energy) Metrics
9
Scope of Work: Identify energy metric points within the unit to trackDevelop FOE metrics and implement in UPM and Optimization Envelope
ResultsWorked with Design Engineer and Energy Technologist to determine energy
targets on the identified metric pointsDeveloped five metrics within the CFU
– Steam to Feed Ratios: Dehex, Debut and Deprop Towers– Absorbed Duty to Feed Ratio: Naphtha Splitter – Excess %O2: Naphtha Fired Reboiler
Developed two metrics within the LEP– Absorbed Duty to Feed Ratio: Dehex – Excess %O2: Dehex Fired Reboiler
Drafted memo
Bundle Cleaning Program-Spring 2015
Scope of WorkAnalyze pre and post-cleaning data on all exchangers cleaned in the Spring
2015 Determine the economic/operational benefit of cleaning each bundle
– Heater duty gains– Reducing hydraulic limitations– Avoiding NTE limit
Results Developed justifications and incentives for bundles that were cleaned Drafted post-audit memo

My Experience
My ExperienceReceived the opportunity to take on
greater responsibility– TAR – CFU Rate Test– FOE Metrics
Lessons Learned – Challenging my assumptions prior to
drawing a conclusionTake Away
– Greater understanding on unit integration and tower design
– Greater confidence as an engineer
