Diagnose poor vacuum, size an ejector system and cut air in-leakage — steam jets, liquid ring pumps and condensers
What you'll learn
Diagnose poor vacuum using a systematic sequence that isolates the failing stage
Read an ejector performance curve to determine whether the fault is load, motive steam or the device
Size a multi-stage ejector system from process load, air in-leakage and non-condensables
Estimate air in-leakage by the standard methods and verify it by pressure rise testing
Run a leak hunt using helium or ultrasonic detection to locate a leak on an operating unit
Select between steam jet, liquid ring and dry vacuum technologies for a given duty
Design suction piping and barometric legs so pressure drop does not consume the vacuum
Specify inter-condensers and after-condensers and understand their effect on the stage downstream
Interpret a dry air performance test and know the limits of what it proves
Inspect ejector nozzles and diffusers and predict the performance effect of the damage found
Requirements
No prior vacuum system experience is required — the principles are built from first principles
Any engineering or technical background is enough to follow the course
Comfortable with basic algebra — every calculation is worked step by step
No software or licence needed
Helpful but not essential: familiarity with distillation or process plant operation
Description
This course contains the use of artificial intelligence.
A vacuum column that will not pull vacuum stops the unit. The ejector gets blamed, a new nozzle gets fitted, and six weeks later the same thing happens.
Almost every refinery has a vacuum system and almost nobody has been trained on one. It is treated as a black box until it fails, at which point the diagnosis is guesswork.
In this course you will learn how to size one, diagnose one and fix one.
WHAT YOU WILL LEARN TO DO
By the end of this course you will be able to
● Diagnose poor vacuum using a systematic sequence rather than replacing parts and hoping
● Read an ejector performance curve and identify whether the problem is load, motive steam or the ejector itself
● Size a multi-stage ejector system from the actual load, including air in-leakage and non-condensables
● Estimate and measure air in-leakage, and run a leak hunt that actually locates the leak
● Select between steam jet ejectors, liquid ring pumps and dry pumps for a given duty
● Design the suction piping and barometric legs that a vacuum system depends on
● Interpret a dry air performance test and know what it does and does not prove
● Identify ejector nozzle and diffuser damage from inspection and predict its effect
HOW THE COURSE IS TAUGHT
● Every sizing and load calculation is worked by hand so the method is visible
● No software needed — the approach transfers to any vendor's selection tool
● Built around real operating faults: wet motive steam, nozzle erosion, unstable operation and the break point
● Five section quizzes and a final exam
● Every presentation is included as a downloadable PDF, so you keep the slides as a desk reference after the course
● Includes the systematic diagnostic sequence used on operating vacuum units
WHAT IS COVERED
● Why vacuum is used, and the absolute pressure scales and conversions that cause most confusion
● Load determination — process vapour, air in-leakage, non-condensables and cracked gas
● Steam jet ejectors — the motive nozzle, mixing chamber and diffuser, and how the device actually works
● Ejector performance curves, the design point, the stable range and the break point
● Multi-stage systems, inter-condensers and after-condensers, and the hogging ejector
● Liquid ring vacuum pumps, seal liquid selection and the cavitation limit
● Dry pumps, mechanical boosters and hybrid systems
● Suction piping design, barometric legs and hotwell arrangement
● Air in-leakage — sources, estimation, helium and ultrasonic detection, and the leak hunt method
● Dry air performance testing to HEI and its interpretation
● Ejector fault signatures — nozzle erosion, diffuser fouling and unstable operation
● Energy improvement by replacing stages with mechanical pumps, and the payback
WHO THIS IS FOR
● Process engineers responsible for a vacuum column or vacuum unit
● Operations and technical engineers diagnosing a unit that has lost vacuum
● Mechanical and rotating equipment engineers specifying vacuum packages
● Maintenance engineers inspecting and replacing ejector internals
● Graduate engineers entering refining or chemical processing
ABOUT YOUR INSTRUCTOR
I am a Chartered Engineer (CEng MIMechE) with over fifteen years in oil and gas, energy and industrial infrastructure, across a range of projects and disciplines.
For more than five years I have also been teaching. Close to twenty thousand engineers have taken my courses, which hold an average rating of 4.26 across the catalogue.
I build these courses because I am genuinely interested in how engineering works and why it fails, and because most technical subjects are taught far worse than they need to be. My aim every time is to produce the course I would have wanted when I first met the subject — practical, honest about what actually matters, and free of the padding that wastes your time.
Requirements
No prior vacuum system experience is required — the principles are built from first principles. Any engineering or technical background is enough to follow it.
