01 Overview

Process reference built for the unit floor

Standards-cited. Visual-first. Deployable anywhere.

The OEG Refinery Reference Series gives operations teams a durable, structured reference for every major process unit and critical equipment type in a refinery. Each module is authored against applicable API, ASME, NFPA, and ISA standards and designed to be deployed as a standalone HTML file — no LMS, no network, no login required.

  • Standalone HTML files that run offline in any browser.
  • Technical values, design parameters, and operating limits are standards-cited.
  • Visual, structured layout built for fast lookup at the point of work.
  • Deploy on an intranet, LMS, control-room workstation, or field device.

02 Why it matters

What changes when crews have the reference

Faster paths to unit-ready

New operators spend their first months building a mental model of the unit. The series hands them one — the why behind every line-up and limit, not just the steps.

Answers at the point of work

Every module is a standalone HTML file that runs in any browser — control room console, field laptop, or phone — with no install, login, or network between a question and its answer.

Earlier recognition, fewer upsets

Crews who understand cause and effect spot abnormal conditions while they are still trends — the difference between a logged deviation and a unit trip.

Cracking does not stop at the riser outlet. Without rapid separation, catalyst and vapour continue to react in the dilute phase — destroying selectivity and generating dry gas.

Open Riser Residence
3–8 s
Post-riser cracking window
Closed Cyclone Residence
<0.5 s
Cracking effectively terminated
Primary Cyclone Efficiency
95–99%
Catalyst recovered per pass
Dilute Phase ΔT Target
<5 °C
Above ROT — overcracking signal
Post-Riser Overcracking
Thermal and catalytic cracking continues in the dilute phase. Every additional second drives unwanted dry gas at the expense of valuable liquid products.
Signal: Rising dry gas rate, falling liquid yield at constant ROT
Catalyst Carryover
Entrained catalyst reaching the fractionator plugs exchanger tubes, erodes pump impellers, and forces frequent slurry circuit shutdowns.
Signal: Slurry catalyst content >2 g/L, fractionator ΔP rising
Selectivity Loss
The RTD design sets a hard selectivity ceiling. An open riser end imposes a physical limit that no operating change can overcome.
Signal: C3/C4 yield increasing, gasoline yield falling vs. design
