Fields of Experience


Mr. Fulk has deep process simulation experience, including helping clients achieve simulation results that accurately represent their plant operations.  Mr. Fulk also has experience in both bench-scale and pilot-scale experimental work in CO2 capture using aqueous amine solvents and has done extensive work in developing custom and commercial numerical process modelling tools focusing on traditional and novel gas treating and sulfur recovery technologies. Specific experience includes:


  • Using simulation tools to reconcile or match plant data as well as troubleshoot mismatches in simulation/plant predictions, including use of proprietary solvents (e.g., alkanolamine mixtures)
  • Providing seminars, training, and client support covering basic process knowledge, detailed technical fundamentals, and simulation for gas treating and sulfur recovery
  • Rate-based modeling for gas absorption, heat transfer, and chemical/catalyst kinetics
  • Experience using AspenPlus®, ProTreat®, and SulphurPro® process simulation tools
  • Development and parameter fitting of thermodynamic and transport property frameworks for reactive aqueous liquids, hydrocarbons, sulfur, and gases
  • Custom model development in several programming languages
  • Modelling extractive distillation, e.g., of ethanol from biofuel fermentation liquors
  • Development and operation of analytical chemistry equipment for gases, liquids, and aerosols including in-situ sampling methods for mist/aerosol laden gases
  • Aerosol measurement, modelling, and control equipment/mitigation strategies
