The Course Content

Gas, contaminants and treating fundamentals

  • Natural gas and refinery fuel gas overview; where sweetening and sulphur recovery units fit in the value chain.
  • Sour gas contaminants: H₂S, CO₂, COS, CS₂, mercaptans, water and other trace components; impact on materials, safety and environment.
  • Product specifications for sales gas, LPG and sulphur; sulphur, CO₂ and dew‑point limits; emission and flaring constraints.
  • Overview of treating options: chemical and physical solvents, hybrid systems, solid adsorbents and membranes – when and why amine systems are preferred.
  • Role and scope of amine treating units and sulphur recovery units in integrated gas processing schemes.
  • Case discussion: mapping the delegates’ facilities – position of amine and SRU units, key bottlenecks and performance drivers.

Amine sweetening chemistry, solvents and configuration

  • Acid gas absorption and regeneration principles: mass transfer, equilibrium and reaction kinetics in contactors and regenerators.
  • Amine solvent families: MEA, DEA, MDEA, DIPA, DGA and formulated/activated amines; selectivity, capacity, energy demand and typical applications.
  • Chemistry of degradation: oxidative and thermal degradation, carbamate formation, heat stable salts; impact on corrosion and performance.
  • Process configurations: single‑stage, split‑flow, selective H₂S removal, CO₂ co‑capture and bulk vs polishing applications.
  • Supporting systems: filtration, carbon beds, coalescers, reclaiming; solution quality monitoring and key laboratory tests.
  • Interaction with upstream and downstream units: dehydration, NGL recovery, compression and SRU feed requirements.
  • Exercise: solvent selection and basic flow configuration for different sour gas compositions and product specifications.

Amine unit design, operation and troubleshooting

  • Typical amine unit flow scheme: contactor, flash drum, exchangers, regenerator, reboiler, overhead condenser, accumulator and surge drum.
  • Key design and operating parameters: circulation rate, lean/rich loading, approach to equilibrium, column internals (trays vs packing), hydraulics and controls.
  • Materials of construction and corrosion control in rich and lean amine circuits; monitoring and mitigation approaches.
  • Common operational problems: foaming, flooding, weeping, excessive amine losses, off‑spec treated gas, high reboiler duty, high corrosion rates.
  • Systematic troubleshooting and optimisation: data gathering, KPIs, use of simulation tools, hydraulic checks and root‑cause analysis.
  • Field‑oriented recommendations: start‑up and shutdown considerations, load changes, solvent changeover and interfacing with operations and maintenance teams.
  • Group case study: diagnosing and resolving a chronic foaming/off‑spec gas problem in an existing amine unit.

Sulphur recovery fundamentals and Claus technologies

  • Drivers for sulphur recovery: sulphur balance, recovery targets, emission requirements and environmental constraints.
  • Claus process chemistry: thermal and catalytic stages; H₂S/SO₂ ratio control; effect of contaminants such as hydrocarbons, ammonia and BTEX.
  • Process flow and equipment of a modified Claus SRU: reaction furnace, waste heat boiler, condensers, catalytic reactors, reheaters, sulphur condensers and degassing.
  • Design and operating considerations: air/fuel control, oxygen enrichment, refractory performance, steam generation and overall heat integration.
  • Catalyst behaviour: types of Claus catalysts, deactivation mechanisms and management of pressure drop and activity.
  • Enhanced sulphur recovery schemes: EUROCLAUS, Super Claus and other variants to increase recovery and efficiency.
