INTRODUCTION:
From super cruise control that allows hands-free driving of a vehicle to smart watches that tell us how much sleep we get, monitor
our health statistics and track our exercise, we are becoming more connected every day. So is chemistry! With this evolution Buckman is
stepping up the mill visibility of our monochloramine chemical systems with cloud connection and actionable insights responding to the
ever-changing mill processes.
Monochloramine Overview
Monochloramines (MCA) are formed in situ by mixing the
monochloramine precursor (MCAP) with industrial grade sodium
hypochlorite in water. The general chemical equation is:
NH3 NaOCl → NH2Cl NaOH
This reaction must occur at the proper pH (>7) and at the
proper molar ratio of MCAP to sodium hypochlorite. If the sodium
hypochlorite is overfed, the reaction is pushed to the formation of
dichloramines.
NaOCl NH2Cl → NHCl2 NaOH
Monochloramines are considered weak oxidizers when
compared to the other oxidizers used in the paper manufacturing
process such as chlorine dioxide, hypochlorous acid, hypobromous
acid, and peracetic acid. Because they are considered to be a
“combined” form of chlorine, monochloramines react to a much
less degree or not at all with other wet-end additives such as dyes,
optical brighteners, starch, retention aids, and sizing agents. They
are highly specific to the microbial contamination in a process.
Because of these attributes, MCA chemistry has become one of the
major oxidant biocides used in the paper industry.
Taking Your MCA Program to the Next Level
Reducing freshwater usage, increased use of and rising
contamination in recycled furnish and greater reliance on anaerobic
digesters for effluent treatment can mean adding more chemistries
to supplement final product specifications and effluent efficiency.
This can lead to increased process variability, unscheduled
shutdowns, lower quality product and additional costs. In response
to these challenges, Buckman offers a new monochloramine
program called Ackumen™ MCA-i™, a breakthrough chemicaldigital solution that uses artificial intelligence with actionable insights
that automatically and promptly stabilize your process.
MCA-i™ combines Buckman’s best-in-class
monochloramine chemistry with state-of-the-art sensing technology,
cloud-based data analytics, 24/7 expert monitoring and analysis,
and accurate predictive modeling to take the work – and the
guesswork – out of you managing your paper machine microbicide
programs and their impact on your effluent system. One significant
feature of the MCA-i unit is a hypochlorite sensor which measures
the activity of the sodium hypochlorite. It is well known that sodium
hypochlorite’s stability is greatly impacted by storage temperature,
storage time and exposure to sunlight. As noted above, to produce
a stable MCA molecule, the sodium hypochlorite and MCAP must be
mixed in water at a precise molar ratio. The hypo sensor measures
the sodium hypochlorite concentration continuously, adjusting the
sodium hypochlorite flow rate to maintain that precise molar ratio.
MCA-i is Buckman’s newest MCA generator that utilizes data
to produce actionable insights. It is capable of monitoring multiple
sensor data, combining them with mill process data to automatically
adjust your treatment program. Your microbiological control
program is pro-actively managed. The generator adds significant
safety features, including Buckman’s patented reaction temperature
technology. Its improvements in automation and technology allow
usage reductions of not only the microbial control chemistries; you
will also benefit from better system/process performance, leading
to significant savings in functional chemistry, improved machine
runnability and improved final product quality. As mill personnel,
you can view key operational parameters of the unit and Key
Performance Indicators (KPIs) from your computer or smart phone.
To prevent disruptions to your process, the MCA-i unit
will alert the Buckman representative of routine maintenance and
potential problems with the unit or the treatment program. The unit
can “learn” to change dosage rates as your process experiences
changes or system upsets, such as high freshwater usage at startup or increased broke usage after a break. This learned insight can
lead to better control and chemical cost savings to you.
MCA-i connects to the cloud and allows Buckman’s Remote
Services Innovation (RSI) lab and global subject matter experts to
remotely monitor the unit and hundreds of process parameters –
nearly 1000 data points – and notifies the Buckman representative
of significant changes to mill processes, such as increased biocide
demand. It works with edge computing and cloud storage to securely
collect and store data, which can then be used to develop historical
patterns. This allows the quick detection of process anomalies.
Benchmarking data with context can be used to help you plan
continuous improvement projects or your new machine/mill. Critical
to achieving the best-in-class performance is linking the “what,
where, when and how”.
