Sulfur Recovery

Application of processes commonly used in the gas processing industry, within refineries to augment the traditional sulfur recovery operations

  • Zero sulfur fuel gas, to facilitate low-level heat recovery as well as avoid acid gas dew point concerns.
  • Simpli-SWAATS – Combines H2S removal with ammonium thiosulfate production, with technology partner, Thiosolv.
  • Claus re-design with direct oxidation of sulfur in the tail gas treating units, avoiding subsequent amine capture and incineration.
  • SweetTreat™ system as redundant sulfur recovery unit required by new regulations.

 

Technology Licensing

Innovative Petrochemical Solutions

  • Hydrocarbon resin feedstock preparation and production. Licenses for high-end resin technology in cooperation with resin production partner, Neville Chemical Company. This includes all resin types, feedstock preparation, and optimization of raw material streams.
    • Steam cracker by-product upgrading for BTX and other products.
    • Mixed plastic recycling into fuels and petrochemicals.
    • Custom-formulated solvents for liquid-liquid extraction and extractive distillation operations.

GTC Vorro Technology for Reducing Octane Loss in an FCC Gasoline Stream

Another U.S. refiner has asked GTC Vorro to study using its catalytic adsorption technology for an FCC gasoline stream to reduce octane loss. The unit is currently losing more than 1 RON in the post-unit selective hydrogenation unit. Many units in the industry lose...

Zero Sulfur in Refineries

The refining industry is pressured. Environmental regulations dominate investment budgets, and often take the top priority in operating expenditures. Mandates on compliance rule over all else, and must be adhered as a license to operate regardless of the logic or cost/benefit analysis. The Gas Processing Industry faces some of the same challenges, and has found different ways to manage H2S that may be useful in the downstream refinery industry.

Zero Sulfur in Steam Cracker Plants

The petrochemical industry is pressured. Environmental regulations dominate investment budgets, and often take the top priority in operating expenditures. Mandates on compliance rule over all else, and must be adhered to as a license to operate regardless of the logic or cost/benefit analysis. The Gas Processing Industry faces some of the same challenges, and has found different ways for managing H2S that are prudent to consider in the downstream industry.
