Process, project and operations-support engineers
LNG Process Engineer
A process-engineering pathway spanning pretreatment, liquefaction, storage, BOG, regasification and the drawings and control relationships that connect them.
Role learning outcomes
A practical curriculum target for the role.
- Trace material and energy relationships across the LNG process.
- Connect process design intent to equipment and controls.
- Recognize process constraints that influence capacity, stability and protection.
- Use controlled engineering documents to support troubleshooting and change evaluation.
Possible evidence in a workplace program
- • Process calculations or approved analyses
- • Technical reviews
- • MOC or project-support evidence where applicable
- • Knowledge assessments
Employer authorization, site qualification and licensing remain separate from LNG University learning records.
Foundation
Build the technical language and system context needed before role-specific depth.
Foundational
LNG Properties, Cryogenics and Phase Behavior
Build the physical foundation needed to understand why LNG equipment, materials, operating limits and safeguards are different from conventional ambient-temperature hydrocarbon systems.
Foundational
Process Flow Diagrams (PFDs) for LNG Facilities
Learn to read an LNG process at system level by following major equipment, streams, operating conditions and material or energy flows on a PFD.
Intermediate
Piping & Instrumentation Diagrams (P&IDs)
Develop the ability to read the detailed relationship among process piping, valves, instruments, equipment, control loops and safeguards on LNG P&IDs.
Core role knowledge
The principal systems and technical subjects most directly connected to the role.
Intermediate
Acid Gas Removal in LNG Pretreatment
Study the removal of carbon dioxide and hydrogen sulfide from feed gas to meet LNG process specifications and protect cryogenic equipment.
Intermediate
Natural Gas Dehydration for LNG
Understand why water must be removed to very low levels before cryogenic liquefaction and how adsorption-based dehydration systems are operated and regenerated.
Intermediate
LNG Liquefaction and Refrigeration Systems
Understand how refrigeration cycles progressively remove heat from treated natural gas until it becomes LNG, and how compressors, refrigerants and cryogenic heat exchangers interact.
Advanced
Main Cryogenic Heat Exchanger (MCHE)
Study the role of the MCHE in cooling and liquefying treated natural gas through close thermal integration with one or more refrigerant circuits.
Intermediate
Boil-Off Gas Management
Understand the sources, collection, compression, recovery and disposition of BOG across storage, unloading, loading and regasification operations.
Foundational
LNG Regasification Process
Follow LNG from storage through pumping, BOG recovery, vaporization, metering and pipeline sendout.
Advanced & protection context
Deeper control, safeguard or specialist knowledge that strengthens decision-making and cross-functional understanding.
Intermediate
LNG Recondenser Systems
Study how a recondenser uses subcooled LNG to absorb and condense BOG while supporting stable suction conditions for high-pressure sendout pumps.
Advanced
Compressor Anti-Surge Control
Understand why surge is damaging, how an anti-surge controller protects the compressor and why recycle-valve response, instrumentation quality and operating margin matter.
Advanced
LNG Stratification and Rollover
Study how LNG layers with different density and composition can form, evolve and potentially mix rapidly, producing increased boil-off gas generation.
Intermediate
DCS, SIS and Emergency Shutdown Systems
Understand the different roles of the distributed control system, safety instrumented system and emergency shutdown functions in an LNG facility.
Advanced
Process Hazard Analysis: HAZOP and LOPA Concepts
Understand how structured process-hazard studies identify deviations, causes, consequences, safeguards and risk-reduction needs in LNG facilities.
