Nordkalk Corporation products

Nordkalk SL powder is suitable for many uses, but the main use is for neutralization.

Nordkalk Filtra G is a granulated slaked lime product. It is mainly used to absorb the sulphur compounds in flue gases but also in other environmental applications such as water purification. Nordkalk Filtra G is in the form of granules, which makes the product easy to handle and minimises dusting. The marine modification is adapted from proven land-based applications.

Marine SO_x scrubbers have been developed to abate the sulphur emissions from shipping. Nordkalk`s desulphurisation concept is based on a dry scrubber where granules made from Nordkalk slaked lime (calcium hydroxide) absorb sulphur from the flue gas of the ship. The benefit of the dry scrubber is the absence of emissions to both air and sea, as the process does not generate any scrubbing waters to be discharged into the sea. Furthermore, the structure of the dry scrubber is simple in comparison to other scrubbers.

Through liming the pH level and buffer capacity of acidic water can be raised to a level where the normal ecosystem survives or recovers. In order to achieve this goal, the pH level of the water must exceed 6 and the buffer capacity must exceed 0.1 mekv/l. Fine limestone powders or magnesium-rich limestone powders should be used for all water liming. The best result is achieved with extra fine products.

As a result of the draining of forests and peatlands and peat production, acidic surface runoff waters can develop at production sites. Depending on the situation of the receiving watercourse, the amount of water and the acidic burden, these waters must sometimes be neutralised before conducting them into the watercourse. In addition to the acidic burden, the runoff water may contain harmful amounts of metals such as aluminium, iron and manganese.

Nordkalk Terra products have been developed especially for soil stabilisation. Lime-based stabilisation products can help achieve a strong and durable foundation cost-effectively with all soil types, even in demanding conditions.

The Nordkalk C-Series product family consists of three products: Nordkalk C2, Nordkalk C5 and Nordkalk C7. The specific characteristics of Nordkalk C-Series products are presented in the table below. The products are available in large and small sacks and in bulk.

Nordkalk offers high-quality concentrated and fine-ground calcium calcite for GCC-production.
