| Project |
Offsite Units for "S-Zorb"
GDU |
| Duration |
3Q 2006- 1Q 2007 |
| Scope |
For Offsite units did
Front-End Loading 2 ("Select" Stage) OSBL Engineering,
plus FEL3 ("Design" Stage) with Procurement |
| Role |
Design Engineer for Scrubber-Oxidation, Cooling Tower & Flare |
| Tasks |
SO2 Scrubber with Sulfite Oxidation
- Developed full engineering and procurement
specification from process data requirements to scrub SO2 by >99.5%
- Issued RFQ to three vendors and conducted
Technical Bid Evaluation of performance parameters, vendor materials
of construction, utilities consumption, and modular design.
- Selected least cost vendor, with
substantially lower cost than vendor who had built all previous S-Zorb
scrubbers
- Value achieved using standard vs. custom
components,
stack height no greater than needed for sampling ,while achieving
twice the oxidation volume for minimum COD
Package Three-Cell Cooling Tower
- Developed full engineering and procurement
specification from exchanger thermal loads to cool 4,250 gpm of C.W.
- Developed sole source justification for
modular, factory-built, road-haulable cooling tower, in just three
cells
- Designed CW sump & basin per
Hydraulic
Inst. Standards
Flare Header Condensation Study
- Analysis of flare header for condensation
in cold weather, using AspenTech's
FlareNet & SimSci's
PRO/II
simulation
- For debutanizer loss of reflux case,
calculated that multi-component vapor would not condense in long
flare header before central knockout drum, even on a cold, wet day
