Mercer Stendal has implemented a new gas combustion project, significantly reducing emissions and boosting energy efficiency in its pulp production.
The initiative involves co-combusting rich gas in the caustic boiler, addressing the challenges of traditional rich gas combustion.
Traditionally, rich gas, a byproduct of chemical recovery, was burned in sensitive boilers, leading to flaring and environmental issues during process fluctuations. The new "Lean Gas Combustion at the Lye Boiler" project, led by Stephanie Stein, introduces a stable and continuous combustion system.
By equipping the lye boiler with a new burner port, Mercer Stendal can now directly feed up to 10.5 megawatts of thermal energy into the boiler, ensuring stable combustion and reducing flaring. The system also improves energy efficiency by producing higher-value steam and reusing chemicals.
"With the lean gas co-combustion project, we have not only improved our environmental balance, but also increased our energy and resource efficiency," said Stein.
The project demonstrates Mercer Stendal's commitment to sustainable practices and sets a precedent for future efficiency-driven upgrades.
