KEMWorks offers process technology for a range of fertilizer products. These technologies are well proven with dozens of reference plants in South America.
Granular MAP/DAP/TSP
Features of the technology:
- JPipe reactor techniques commercialized since 1986. The JPipe reactor functions alone for MAP and in conjunction with a preneutralizer for DAP at high capacities.
- Single train plant up to 200 tonnes/hour DAP or MAP.
- Optimization of water balance provides flexibility of acid strength and source.
- An Advanced Recycle Control System (ARCS) reduces the recycle ratio by about 30% compared with conventional processes resulting in lower capital cost.
- Fuel and electricity consumption reduced by about 25% compared with conventional processes.
- Simplicity in operation leads to lower maintenance costs.
With increasing fuel and raw material prices, the economics of producing granulation products has been adversely affected. We can also offer a number of proven methods to modify granulation plants to reduce energy costs, including warm-air recycle, waste heat ammonia vaporizers, and bulk flow cooling.
Powder (ROP) SSP/TSP
Features of the technology:
- Designs are available from 10 to 130 t/h using Belt-Den technology.
- Operations since 1984 with direct dilution of the 98% H2SO4 with either water or H2SiF6.
- No liquid effluents when diluting with H2SiF6. • The turbine mixer-belt den combination produces a low density, porous product that is easy to granulate.
- For SSP permits operation with rock slimes or ground phosphate rock in the form of slurry with H2SiF6 from the scrubbing system.
Granular NPKS with micronutrients
Features of the technology:
- Standard designs available from 10 to 100 t/h.
- Flexibility in raw material source: ROP SSP and TSP, DAP, MAP, Urea, Ammonium Sulfate, and Potash.
- An improvement method to accurate fortify the fertilizer with micronutrients, including: Zinc, Boron, Copper, and Manganese. • Addition of elemental sulphur for high S grades.
- An Advanced Recycle Control System (ARCS) minimizes recycle ratio for lower capital cost.
- No Propriety Equipment for a more competitively priced plant.
