Fluid Catalytic Cracking

Fluid catalytic cracking (FCC) plants are used to convert heavy distillates into lighter ones like gasoline and diesel. The feedstock is primarily vacuum gas oil, often mixed with refinery residues.

FCC units produce sulphur dioxide and nitrogen oxides (NOx) and these particulates are tightly regulated. This places refinery operators under pressure to manage NOx emissions and ensure they do not impair air quality.

We offer various solutions to enrich air regeneration with oxygen and to boost capacity. These include LoTOx technologies to help control particulates, sulphur dioxide and NOx emissions from the FCC.

LoTOx technology is a patented innovation that uses ozone to selectively oxidize insoluble NOx to highly soluble species that can be easily removed in a wet scrubber. The benefits include increased capacity, greater flexibility in the choice of feeds, increased conversion rates and reduced emissions.

Partial Oxidation

Partial Oxidation Plants are used to form hydrogen, carbon monoxide, carbon dioxide and water from the residues (liquids, highly viscous hydrocarbons) of the refining process.

The products can be used as synthetic gas, fuel gas or feed for hydrogen recovery. With tailored oxygen supply for Partial Oxidation (POX) we can offer you the following benefits:

  • Cleaner and better reuse of residues
  • Broader economic base of the refinery
  • Higher flexibility through a wider range of products
  • Handling of refinery feed compositions within a wide range
