Working as a process engineer for a new sulfur derivatives project. The project consists of four processes; Linear Alkyl Benzene Sulfonic Acid (LABSA), ethoxy alcohol sulfonate (AES), Bentonite Pastilles, and Sulfur Pastilles as an intermediate feed for Micronized Sulfur unit. My responsibilities are to oversee, review and assist the basic and detailed engineering work to be undertaken by the EPC contractor PegasusTSI, Inc. It also includes project planning and coordination of technical matters.

My engineering experience with TASWIA sulfur derivatives project:

- Review of site plot plan and equipment location drawings.
- Worked closely with process licensors to generate process Flow Diagrams, Utility Flow Diagrams.
- Review mechanical datasheets and equipment specifications.
- Review instrument specifications and interlock matrix.
- Participated in P&IDs, constructability and HAZOP meetings.
- Performed hydraulic calculations & verified valves design.

Project Management experience with TASWIA:

- Conducting commercial & technical bids evaluation for quotations.
- Review of scope of work and contract terms and conditions
- Coordination between EPC contractor and Royal Commission RC
- Coordination between EPC contractor and Saudi Electricity Company

Worked as a process engineer in the US$1 billion upgrade project at SAMIR Refinery. My responsibilities included process units calculations to verify design specifications are met during test run. Also, performed process optimization for Hydrogen production unit, Diesel Hydrotreater and Fuel Hydrocracker unit. I was also heavily involved in the precomissioning and commissioning activities of the upgrade project units.

Technical Experience:

Hydrogen Production Unit:

- Use of ProII model to monitor the performance of HPU during test run
- Primary steam reformer efficiency verification.
- Calculation of Zinc Oxide bed life and evaluation of pre-reformers' catalyst activity, temperature profile and life.

Diesel Hydrotreater Unit:

- Development of overall process monitoring tool
- Evaluation of catalyst performance, which includes WABT, LHSV and deactivation calculations.
- Calculations of feed exchangers duty and fouling rate.
- New piping system project to introduce Light Straight Run Naphtha from Merox unit to DHT that involved; pipelines sizing, pressure drop calculations and control valves preliminary design.

Fuels Hydrocracker Unit:

- Feed pumps performance calculations.
- Determination of 1st stage and 2nd stage reactors conversion.
- Evaluation of 1st and 2nd stages catalyst performance that includes
Catalyst Average Temperature CAT, 1st and 2nd order kinetics
normalization and rate of deactivation.
- Calculation of fractionator Recycle Cut Point and products yields.

Operation Experience:

- Pre-commissioning & commissioning of upgrade project units: Hydro-testing, chemical cleaning, leak tests, tightening tests, inspection and dry-outs of heaters, columns and reactors, mechanical test runs for compressors and pumps, catalyst loadings and sulfiding.
- Overall Performance Test Run for upgrade process units.
- Performance monitoring, Debottlenecking and Optimisation.

I had an internship with Preem Petroleum AB, Gothenburg Refinery. I was working as a process engineer trainee in the Technical Department and my responsibilities were primarily focused on providing technical services for refinery crude unit: \n \n- Monitoring of crude preheat exchangers fouling, \n- Determination of crude furnace efficiency \n- Air-cooler pressure drop calculation \n- Laboratory test related to green diesel project.
