Verdis GTD technology

VERDIS GTD IS A STATE-OF-THE-ART, SCALABLE, MODULAR, 100% CLEAN TECHNOLOGY

The patented Verdis GTD technology captures and converts 100% of the free associated natural gas into ultra clean diesel, producing 0% emissions.

The Verdis modular design is fully scalable, ranging from micro GTL units to large scale petrochemical plants.

VERDIS GTD PROCESS SCHEMATIC

  • Fischer-Tropsch based Gas to Liquids (GTL) process: key differentiation is patented catalyst
  • Only product converting gas directly to ultra-clean diesel in single pass, at low-pressure, no hydro-cracking
  • Significant savings in capital & operational cost
  • By-products: water, surplus electricity. Units are self-powering (excellent for remote, desert or arctic use)
  • Process reviewed & endorsed by the World Bank Global Gas-Flaring Reduction Partnership

STEP 1 – INPUT GAS SCRUBBING

  • Higher combustibles (ethane, propane, etc.) improve diesel production
  • Inerts have no effect
  • H2S degrades catalyst performance and must be removed, to a level >1 PPM
  • This requires a standard gas scrubber (SulfaTreat or zinc oxide possible)
  • OR: Canada Chemical Corporation has a proprietary Batch Oxidation technology to convert H2S to elemental sulfur

STEP 2 – VERDIS GTD UNIT STARTUP

  • A small amount of hydrocarbon raw gas is burned in the reformer
  • This is used to pre-heat the entire train.
  • As delivered, the Fischer-Tropsch catalyst contains cobalt oxide (the metallic form is pyrophoric when exposed to air and would be dangerous to handle).
  • To activate the catalyst for FT syngas conversion: catalyst reduced to metallic cobalt inside  FT reactor using hydrogen

STEP 3 – SYNGAS PRODUCTION

  • Feed gas moves into a highly-advanced plasma-based Syngas Reformer
  • Required temperature and pressure (50PSI) is achieved
  • Gas fully prepared for conversion in next stage: H2:CO ratio sought 2.0
  • (Includes compressor, coolers, water knockout, piping to storage)

STEP 4 – ULSD DIESEL PRODUCTION

  • High capacity Fischer-Tropsch  reactor comprised of 4 inch catalyst tubes
  • Pressure <200PSI, cobalt catalyst crystallite size 16NM
  • Syngas converted into diesel, water, naptha, tail gasses
  • (Includes FT reactor, Dowtherm ® coolant condenser, coolant circulation equipment, synthesis gas recycle loop)

STEP 5 – ULSD COLLECTION

  • FT Reactor products are separated and captured in one ‘cold trap’ and one ‘hot trap’
  • They are then directed to different storage tanks on site, waiting tanker trucks, or possibly pipelines, for further distribution to end-users
  • The process continues once started. 350 days of uptime per year is anticipated
