F2 SATELLITE PLANT
Fluorine production
at client facilities
THE PROJECT. Solvay Fluor manufactures
elemental fl uorine (F2) at its sites in Bad Wimpfen
(Germany) and Onsan (Korea). For some time now
Solvay Fluor has been investigating the possibility
to replace NF3 by Solvay’s elemental fl uorine (F2)
for CVD (chemical vapour deposition), for use in
chamber cleaning in the fl at panel (LCD) and thin
fi lm photovoltaic industries. F2 has a higher
effi ciency than NF3 and a zero GWP (global
warming potential) compared with more than
10 000 GWP for NF3, making it a perfect fi t with
the Group’s sustainability strategy. If we are
successful, the market potential is enormous: a
single PV or LCD plant can consume several ten
to hundred tons per year of pure F2!
Based on this fact, Solvay Fluor developed the
only rational solution to offer to its customers:
a unique modular “F2 satellite” concept for
on-site F2 production, avoiding F2 transport while
ensuring continuous, uninterrupted F2 supply.
This allows the customers to achieve signifi cant
investment savings, while Solvay Fluor avoids
accumulating stocks at the customer sites,
investment in packaging and shipping costs.
Solvay Fluor, with its more than 35 years of
experience in the manufacturing and handling of
F2, is working on several fronts in close
cooperation with major CVD chamber suppliers
as well as end-users. The F2 satellite concept is
easily replicable on different sizes and is being
considered in various countries. A new high purity
F2 is available to serve the semiconductor
industry in addition to the fast growing PV and
LCD markets.

SILICATED SODIUM BICARBONATE AS
A NEW AND SAFE SOLUTION TO COMBAT
PARASITES
An end to parasites
THE PROJECT. Parasites such as lice in
children, red chicken mite in poultry farms
and insects in grain silos adapt and eventually
become unresponsive to conventional
insecticides.
The proposed solution, based on sodium
bicarbonate, has proved its effectiveness, and
its ‘physical’ means of operation rules out any
possible adaptation of parasites.
Mixing well-known products (sodium bicarbonate
and silica) that are harmless to humans and
animals gives a ‘silicated’ sodium bicarbonate
used in the form of powder or gel.
This mixture acts by physical effect: dehydrating
and / or suffocating the pests that have thus no
chance to mutate and adapt.
These new products are being manufactured
and developed in partnerships in Italy, France
and Spain. This approach to new markets through
partnership was presented and awarded during
the 2006 Solvay Innovation Trophy. Initial market
response is good.

APPLICATION OF THE ‘ZERO EFFLUENT’
CONCEPT TO THE WASTEWATER FROM
MEMBRANE ELECTROLYSIS AND VINYL
CHLORIDE PROCESSES IN RUSSIA
PVC: ultra-clean plant
THE PROJECT. Solvay has developed a
technology – unique in the world to our
knowledge – to treat effl uent from the vinyl chain
for recycling as raw material for the manufacture
of PVC.
This advanced technology demonstrates that
emissions into the environment can be further
reduced where a new vinyl production unit is set
up in a sensitive area where legislation is
particularly strict.
More precisely, the project is to treat an
electrolysis effl uent and another effl uent from
the production of vinyl chloride, the monomer
precursor of PVC. The nature of these treatments
remains confi dential at this stage, because
intellectual protection procedures are underway.
Pilot projects have been conducted successfully
at Rosignano (Italy) and Dombasle (France).
Industrial implementation is foreseen in the new
PVC production unit (330 000 tons / year) at
Kstovo in the region of Nizhny Novgorod (Russia).
