Distribution,
customer and
technical services
Praxair operates a 24 hour a day,
365 days a year delivery service.
Our CO2 is delivered in road
tankers carrying payloads of up to
24.5 tonnes.
Product knowledgeable Customer
Services Coordinators simplify
order processing, and a dedicated
Application Sales team offers help
and solutions in order to achieve
total service provision. We are
confident of the service we can
and do provide.
Many international, “blue-chip”
companies are listed amongst our
customers.
Praxair has a full technical and
engineering support service. We
supply and install a wide range of
CO2 storage vessels and
associated equipment, and offer a
comprehensive maintenance
service for those customers who
own their own equipment. By
installing telemetry onto the CO2
storage vessels, Praxair also helps
to manage CO2 stocks and
optimise customer’s deliveries.
Quality assurance /
CO2 specification
CO2 is a tasteless, colourless,
non-toxic, non-flammable,
liquefied gas. It is a very small
part of the atmospheric air around
us (approximately 0.03%) and can
exist in three states – as a gas, a
liquid and in solid form (Dry Ice).
Praxair operate a certified, fully
Integrated Management System
(IMS) for the following standards:
ISO - 9000:2000 Quality Standard
ISO - 14001 Environmental
Standards
ISO - 22000 Food Safety Systems
OHSAS - 18001 Health & Safety
Standard
Praxair’s CO2 is supplied to the
European Industrial Gases
Association (EIGA) Specification
DOC70/99, suitable for use in both
the food and beverage industries.
Praxair is flexible on meeting
customer’s quality requirements,
including certification by batch or
delivery.
CO2 specification and Material
Safety Data Sheets are available
on request.
Praxair – One of
Europe’s leading
producer of CO2
Praxair is one of Europe’s leading
producers of CO2. Praxair own and
operate CO2 production plants in
Holland, Norway, UK, Germany
and Italy. A key part of Praxair’s
supply strategy is its ability to
transport bulk CO2 between its
terminals across Northern Europe,
and British Isles using one of its
purpose built ships. The ability to
move CO2 quickly around Europe
provides Praxair with its very
strong “Security of Supply”
position.
Praxair’s CO2 for the UK and
Ireland markets is produced at our
plant in Wilton, Teesside, or from
the plant located in Billingham as
well as from our European
production sites, which is
imported throughout dedicated
import terminals on the Thames
estuary in the South, or Teesside
in the North. From our terminal in
Teesside we can also export from
the UK to the other European
terminals. Praxair is the only
company in the UK and Ireland
with this CO2 import capability,
giving us a huge advantage when
customers require secure
supplies.

Before Cleaning
Liquid CO2 is one of the most
versatile of all industrial gases,
with a wide range of applications
throughout the food and
beverage, water treatment,
firefighting and horticultural
industries. Some of the key
applications are:
Food Processing
CO2 is widely used in the food
industry for cooling during meat
processing, crust freezing,
packaging and temperature
controlled distribution. CO2 is
used in modified atmosphere
packaging (MAP) for a wide range
of convenience foods which
significantly extends their shelf life
owing to its unique bacteriostatic
properties.
CO2 can also be used as a more
humane method of anaesthesia
for poultry and pigs prior to
slaughter. Trials have shown that
better quality of meat is achieved
because the bird or animal’s
musculature is relaxed and less
meat goes to waste.
Solvent
Super and sub critical CO2 are
used as a solvent for various
processes, including flavour
extraction such as caffeine and
vanilla.
Horticulture
CO2 enrichment of greenhouses is
an efficient means of improving
the crop yield for fruit, vegetables
and flowers. CO2 can also be
used for the eradication and
control of pests on flowers and
crops.
Industrial
CO2 is used for a wide range of
industrial and safety applications,
for example: firefighting; welding;
tobacco leaf expansion; mould
hardening in the foundry industry;
PPC (precipitated calcium
carbonate) production; de-liming
in tannery operations and as a
carbon additive for lubricants.
Dry Ice production
CO2 is also used to produce
DrikoldTM
, this is Praxair’s trade
name for Dry Ice which is CO2 in
its solid state at -78oC. Drikold dry
ice has a wide variety of
applications, for example:
chilling or freezing food for the
airline catering industry; Dry Ice
Blast Cleaning; transportation of
medical and pharmaceutical
products; and as a “fog” effect in
theatres and nightclubs.
Beverages
CO2 is widely used for
carbonation, packaging and as a
process gas in the soft drinks,
brewing and mineral water
industries.
Significant increases in the use of
CO2 have been seen in the
packaging of beverages in cans
and PET bottles to meet the
growing demand for the “take
home” trade.
pH control for wastewater
CO2 is ideal for lowering the pH
value of alkaline waste water.
CO2 is a more cost effective and
safer alternative than mineral
acids traditionally used,
particularly where bulk CO2 is
already in use on a soft drinks or
brewery site. With CO2 being a
weak acid dosing is more gentle,
and maintaining the pH value at
the required level is also easier
than dosing with a strong mineral
acid. CO2 can also be used for pH
stabilisation in paper making
processes.
