Industrial production of NEREA® zeolitic products for the agricultural industry: alternatives for the curing-drying process
Abstract
NEREA® Substrate, NEREA®
Fertilizer and NEREA® Plus products are
registered to be used as a substrate, soil fertilizer and foliar fertilizer,
respectively, for the agricultural production. The NEREA®
production technology
does not generate waste and is adaptable to industry conditions, which lead to
that its implementation is in a constant improvement. The production process
includes, in a first stage, the modification of the mineral with aqueous solutions
of hydro-soluble NPK chemical fertilizers. In a next stage, called ―curing-drying‖,
the material is arranged in the bed form to develop the incorporation of nutrients
(N, P, K, etc.) into the zeolite matrix through ion-exchange and adsorption
processes. This research was carried out at NEREA® San Andrés Experimental
Plant, Cuba, to develop alternatives for the ―curing-drying‖ of these products in
order to increase the productive capacity and allow greater adaptability of the
technology. The zeolitic mineral from the San Andrés deposit was used, which
is a mixture of clinoptilolite-heulandite and mordenite type zeolites. It was
determined that the curing-drying of the product packaged directly in bags
increases productivity up to 0,83 t/h, which turns out to be 0,41 t/h higher than
the current process. NEREA® products turned out to be enriched with the
nutrient’s N, P, K and other micronutrients necessary for the proper
development of crops, which was evidenced by using XRD, SEM, FTIR and
other characterization techniques
