MinPlus B.V.

MinPlus is produced in the patented “Controlled Thermal Conversion” process (CTC) from the otherwise discarded mineral fraction of paper recycling. The process is CO2 neutral. Small particulate lime and clay minerals are re-used in a wide-pore layered highly reactive mineral mixture with a melting point of more than 1.300 °C. The powdery MinPlus additive is pneumatically dispersed into the empty drafts of waste incinerators at typical flue-gas temperatures of 800 – 1.100 °C, where it binds HCl, SO2 and HF upstream of the boiler superheater parts, simultaneously preventing the formation of hard deposits and high-temperature melting corrosion of downstream boiler parts. Dosage rates of typically 1,5 g MinPlus per Nm3 of flue-gas result in significantly increased availability and increased interval length between planned stops, while simultaneously reducing the amounts of traditionally applied flue-gas cleaning additives like lime, sodium hydroxide, or sodium bicarbonate.
