Why do I need a Pigging
System?
Historically this has been the main reason why process
companies required a pigging system.
When a
batch of product has finished transfer from a holding tank along a
pipe then into a filler, storage tank or tanker there is always
product residue remaining that the pump cannot evacuate. Even
gravity fed lines don’t evacuate all of the product.
Generally, more
viscous products leave more residue
behind.
Introducing a pig into the line enables this residue
to be pushed into the filler, storage tank, tanker or even the final
package. This residue is good product and can now be sold. This is
obviously good for company profits, but it also increases the
efficiency of that particular line and perhaps gives you that edge
over a competitor that you want.
Traditionally
many companies attempt to chase product residue down the pipe with
water or blow it with a gas medium. Each of these created other
issues with
the products concern, which were offsetting the
gains.
Using water to chase the product creates a
product/water interface and judging or measuring by eye or by a
sensing device is unreliable and risky. Longer and larger diameter
pipelines have greater interfaces to deal
with.
Pigging
the line after production removes this
issue when a
product transfer is complete. Also, water residue that remains after
CIP or washout creates a product/water interface which means running
of a great deal of valuable product before the quality is
acceptable. Pigging the line after CIP or washout again removes this
issue. It is
possible to start up with good product
immediately.
This is one of the hidden benefits with pigging
systems.
As water
usage is another environment issue it is
becoming expensive.
Normally the first part of any CIP cycle is to flush
out the product residue with water for a period of time before
actually proceeding with the cleaning process. If the product has
been evacuated with a pig then there is no requirement for a lengthy
flush out. This could be reduced to a minimum, saving valuable time
and money.
Faster
product change-overs
As
companies expand their product ranges and product variations there
is increasing pressure to accommodate this in previously dedicated
pipelines. Each variation of product has the effect of reducing
batch sizes and each change over of batch accounts for losses in
product and less productive man hours. Pigging resolves both of
these issues. As
explained earlier pigging allows you to pack the product residue
between batches, which significantly reduces losses. It also speeds
up product change-overs as you do not need to wash for as long. If
there is only a slight colour or perfume change it may be possible
to follow on immediately with the next
product.
Product
Separation
HPS pigs
can be used to separate one product from another eg dark chocolate
from milk chocolate. This is generally required where water cannot
come in contact with product or product line. It is also required
for extremely long pipelines that can carry more than one batch of
product at a time. An example of this was a recent HPS installation
for a large chocolate manufacturer in the
UK. This
client has a 5 inch diameter pipeline that runs 500 metres. HPS Pigs
are used to separate dark & milk chocolate batches that are in
transfer at the same time in one pipe.
