SUMMARYKnovel helps engineers tackle chemical manufacturing
challenges such as corro-sion prevention, process hazard analysis,
EHS compliance, industrial hygiene, and energy efficiency. This
solution story illustrates a practical example of how Knovel can be
used to ensure food safety in chemical processing.

ADVANTAGES OF USING KNOVEL
• Contains the information necessary to compare the efficacy of
numerous sanitizers based on their application.
• Interactive content features allow engineers to quickly
identify and compare corrosion and resistance data for metals in
the presence of chemicals, and easily export this data for lab
comparison.
• Includes coverage of hazardous chemical permissible use limits
and handling guidelines, which allows engineers to understand both
the practical and regulatory implications of design and chemical
choices in the same platform.
KNOVEL SOLUTION STORY: Food Safety in Chemical Processing
BUSINESS NEED Ensure Safety in Sanitizer Selection for Food
Additive Processing
A chemical manufacturer primarily uses stainless steel for its
food additives processing equipment. The company needs to find a
chemical which will be used for sanitizing the equipment as well as
rinse water treatment.
An engineer for the manufacturing plant is asked by his manager
to recommend a sanitizer for the equipment and rinse water
treatment. The engineer is also asked to evaluate the storage
requirements, human health hazards, disposal methods of the
selected sanitizer.
USER CHALLENGE Recommend a sanitizer that is safe, effective and
avoids equipment corrosion
The engineer must identify a sanitizer to clean a stainless
steel tank that is being used in the production of additives for
the food industry. The sanitizer will be used to clean the tank and
for rinse water treatment.
The engineer must find a sanitizer than can be used effectively
within legal limits, as well as identify toxicity, storage,
handling and disposal guidelines. Considering the frequency of use
for the sanitizer, the engineer must also find a sanitizer that
avoids equipment corrosion for the stainless steel tanks.

for stainless steel tanks

KNOVEL SOLUTION STORY: Food Safety in Chemical Processing
The engineer begins by searching for “stainless steel vessel
sanitizer” in Knovel, and after scanning the text section snippets
in the search results, clicks on a text section from Food Plant
Sanitation – Design, Maintenance, and Good Manufacturing Practices
(2nd Edition).
FPO OR GRAPHIC DEVICE
Within the section, the engineer finds a table that lists
several main groups of industrial sanitizers such as active
chlorine, iodophores, quaternaries, acid sanitizers and chlorine
dioxide. Based on the reported attributes including organism
control, residue, and stability, chlorine dioxide appears to be the
best candidate (and it’s environmentally friendly!) The section
also has information on effective disinfection concentration
levels. Though each of the sanitizers can hypothetically be used
with stainless steel equipment, the engineer decides to
double-check the corrosiveness of chlorine dioxide.

Good Manufacturing Practices (2nd Edition).

KNOVEL SOLUTION STORY: Food Safety in Chemical Processing
Within the interactive table, the engineer finds multiple
experimental data points for the corrosion of stainless steel in
the presence of chlorine dioxide. The data is available for
multiple stainless steel alloys, and reports mills per year
corrosion rates with associated concentration levels and
temperatures.
The engineer chooses to export this data into Excel, so that
they can assess the impact the effect of chlorine dioxide on their
own equipment.
The engineer returns to the Knovel search query and enters
“chlorine dioxide steel corrosion.” From the results pane, the
engineer selects the Interactive Tables facet on the left, which
yields a result on chlorine dioxide corrosion data for metals from
the Corrosion Survey Database (COR-SUR)
Now that the candidate sanitizer has been selected, the engineer
needs to find out detailed toxicity information about chlorine
dioxide. The engineer returns to Knovel search, and enters
“chlorine dioxide toxicity.” The engineer then clicks on the
chlorine dioxide text section from the Sittig’s Handbook of Toxic
and Hazardous Chemicals and Carcinogens (5th Edition).

Within the resource, the engineer finds a wealth of information
about the handling guidelines and toxicity concerns for chlorine
dioxide, as well as air exposure limits, human health
effects/symptoms, storage guidelines and disposal methods.

CONCLUSION
Having used Knovel to performed a full assessment of available
sanitizer options for stainless steel equipment, the engineer has
decided that chlorine dioxide is the best sanitizer candidate.
Armed with corrosion information, permissible use guidelines
(maximum residue, water concentration, air concentration), as well
as safe handling and disposal guidelines, the engineer can now
return to the plant and test the efficacy of this option on their
processing equipment.
Using Knovel, the engineer has identified a sanitizer candidate
and is equipped with the information he needs to test the
option.
