In 1817, Francisco Cros installed his
first chemical plant in Badalona
(Spain). In 1904 Amadeo Cros founded
the Company S.A. Cros, which
became a pioneer in the chemical
industry.
Intecsa was one of Spain’s biggest
engineering companies. It belonged to
Dragados, the Spain’s leading
construction company.

In 1990 Krupp Uhde acquires 50% of

The full merger of S.A. Cros and ERT in
1988 led to the formation of the Ercros
Group, whose agrochemical division
was called FESA-ENFERSA.
In addition to INCRO’s manpower,
FERTIBERIA & INTECSA-UHDE large
experience allows INCRO to count with
additional specialized engineers and
operators in fertilizer plants design & start-
up for the development of any project,
regardless of its size & scope.
Two pilot plants are installed in
FERTIBERIA to test new products /
processes.
More than 70 references have been
successfully completed on the fertilizer
field.

PROCESS DESCRIPTION
Atmospheric Evaporation Technology
INCRO has developed an Atmospheric Evaporation Technology specially
recommended to treat any kind of liquid effluent. The process has been
patented and homologated in several countries.
The process is based on the capacity of non-saturated air of absorbing
water if a suitable interchange surface is provided. INCRO has developed
an Evaporation packing (AEP) to provide the required air - liquid effluent
interface. It has the following main features:
Ambient Air
EffluentsSpraying System
Concentrate
Saturated Air
Original systems
They use renewable energies, sun and wind, for evaporation.
They require power only for the wastewater circulation.

Technology Advantages
OPERATION AND MAINTENANCE
• Fully automatic units, without any personnel
ENVIRONMENT
• Elimination of liquid effluents
CAPACITY
• Modular design allows easy adaptation for any capacity
INCRO’s Atmospheric Evaporation Technology
• Concentrate is reused in granulation section
• Clean gas effluent. It could be even eliminated in ECO
• ECO system allows pure water recovery
INCRO owns three portable pilot plants: one for evaporation and two
flexible plants for evaporation or evaporation-condensation.
RESEARCH & DEVELOPMENT
INCRO’s Atmospheric Evaporation Technology
INCRO’s Atmospheric Evaporation Technology References
1998 FERTIBERIA – Spain
10,000 m3/y water evaporated
The Evaporation plant was designed to
treat the liquid effluent from two identical
NPK plants, which were not able to recover
into the granulation section all the water
employed in the scrubbing system.
The 2 m3/h liquid effluent from the
scrubbing system was concentrated to 0.5-
1 m3/h, using an E-system (based on
natural evaporation)
Due to the distance to the granulation
plant the concentrate was sent to a pond,
being recovered at different rate
depending on the manufactured NPK.
INCRO’s Atmospheric Evaporation Technology References
1998 UEE – Spain
4,500 m3/y water evaporated
The Evaporation plant was designed to
treat the liquid effluent from an explosive
plant. The concentration of AN is 5%.
The 0.60 m3/h liquid effluent from the plant
is concentrated to 0.06 m3/h, using an EM-
system (based on mechanized
evaporation).
The concentrate produce is sold as a
fertilizer.

2001 PETRONAS / NAFAS – Malaysia
22,000 m3/y water evaporated
The Evaporation plant was
designed to treat the liquid effluent
from a steam granulation plant.
The 5 m3/h liquid effluent from the
scrubbing system is concentrated
to 2.5 m3/h, using an EMC-system
(based on heated mechanized
evaporation).
The evaporation plant is located
within the NPK production
building.
