Contact usThe causticization process is a transformation from the sodium carbonate 'by-product' formed to caustic soda. The recovered sodium hydroxide is re-used in the process. The recalcification (conversion of limestone to lime) of the calcium carbonate produced achieves a lime yield of 90 to 97%. To compensate for the losses, a replenishment of high purity quicklime (from an external source) is required.

Features & Benefits
Features
- pH control: at a pH value of 12.6, lime has a high neutralization value, which ensures a suitable and correct pH increase.
- High purity: Carmeuse provides lime with a high CaO content and low impurities.
- Carmeuse Partner in experience: Carmeuse has more than 160 years of experience in the processing and transformation of lime-based products.
Benefits
- Unique pH neutralization: lime provides efficient hydroxide ions needed for the transformation of sodium carbonate to sodium hydroxide.
- Lower flush rate of lime: the high purity enables a lower replenishment of the lime and increase the recycling loop.
- TechPartner support: our technical support can help you optimize your processes and reduce unwanted process side effects.
- Evaluation circular economy projects: recovery and recycling of customer products.
