The Industry at a Glance
Cement manufacturing accounts for approximately 8% of global CO₂ emissions, with kiln fuel costs representing over 50% of total production costs. Regulatory pressure on carbon reduction and energy efficiency is intensifying worldwide. Oxygen-enriched combustion and oxy-fuel carbon capture are emerging as essential technologies for cement producers to meet decarbonization targets while improving profitability.
Where Our Products Are Used
-
1
Kiln Oxygen-Enriched Combustion
VPSA-O₂ plants supply enriched oxygen to rotary kilns, increasing flame temperature by 100–300°C for faster, more complete fuel combustion.
-
2
Alternative Fuel Enablement
Higher oxygen concentration enables co-firing of plastic waste, refuse-derived fuel (RDF), and biomass — reducing coal dependency by up to 20%.
-
3
Oxy-Fuel Combustion for Carbon Capture
VPSA oxygen feeds oxy-fuel combustion systems, producing flue gas with 75%+ CO₂ concentration for efficient capture and utilization.
-
4
Clinker Quality Enhancement
Stabilized high-temperature combustion reduces free calcium oxide (f-CaO) content and increases clinker liter weight and strength.
-
5
Multi-Kiln Centralized Oxygen Supply
A single VPSA plant distributes oxygen to multiple kiln lines and gas consumption points, maximizing system efficiency.
