Dosing of oxidant agents in the collectors to
minimise the hydrogen sulphide generation
problems:
• Installation of a gauge to measure hydro-
gen sulphide in order to determine the
levels and the profile of the hours at the
point where the problems were detec-
ted.
• Retrieval of data and dosing proposal.
•Testing begins, controlled dosing by
means of a regulated pump.
• Removal of the hydrogen sulphide mea-
suring gauge and verification of its effi-
cacy or extension of the test after the
necessary corrections to control the
concentrations.
Dosing devices were installed and in some
plants, the water exits and the aspirations
of the air extraction system were modified
in a localised manner and in the drying area.
For safety purposes, ancillary equipment
was installed for the comfortable and safe
handling of chemical solutions, such as
girders and hoists that make it possible to
transfer the hoppers of the product to their
location over the dosing machine. Dilution
water valves, eye-wash solutions, and a sa-
fety shower were also installed.
