The difference between the process now and then is how advanced the technology has become and the many challenging criterias set.

Gas purification and seperation

4 key steps


Gas seperation and purification

  • absorption of gasses using liquids
  • each liquid absorbs a certain gas from the Grade B Syngas
  • liquid containing each gas are separated in different columns
  • Each column undergoes a reaction to produce pure CO, CO2
  • transferred to storage
  • "Grade C Syngas – raw Syngas that comes from the gasifier that contains approximately 30% hydrogen and carbon monoxide combined, 30% carbon dioxide, hydrocarbons and nitrogen.
  • Grade B Syngas – is the Syngas that has undergone some polishing to remove hydrocarbons and has been reformed increasing the combined amount of carbon monoxide and hydrogen to around 70% with carbon dioxide and nitrogen making up the rest.
  • Grade A Syngas – is further processing of the Grade B gas to increase the purity of the hydrogen to >98.0%"


SO2 catalyst

  • Sticks into "spiky" nickel particles

  • oxidation of waste metals
  • To insure metals are stable when returning to Canada. For safety and environmental reasons
metal + oxygen MO
  • CO addition
  • New CO added
  • Some CO recycled from pellet and powder plant
Ni + 4CO Ni(CO)4


  • Reduction equation
NiO + H2 Ni+ impurities + water
  • spins to ensure all the nickel is oxidized.
  • takes around two weeks

Main Nickel products

ValeProcess: Nickel carbonyl is produced through the reaction of nickel metal with carbon monoxide gas. This forms a volatile nickel carbonyl gas, which is then thermally decomposed to yield pure nickel metal. Purity: The nickel obtained through this process has 99.9% purity, comparable to electrode purification. Energy Consumption: The nickel carbonyl process is generally considered to be energy-efficient compared to some other refining methods.

NickelbergProcess: Nickel is refined through electrolysis. partially purified nickel ore is dissolved in a solution, and the nickel ions are then reduced and deposited onto a cathode. Purity: This method produces a 99.9% purity. Energy Consumption: Electrolysis requires alot of energy, making this method relatively energy-intensive.
