CTS30 Compression plate seal
Liquid mounted primary seals are the most effective seals with respect to emission reduction for external floating roof tanks. CTS supplies several types of liquid mounted primary seals such as shoe plate seals and liquid mounted foam seals. Liquid mounted seals however will have to deal with liquid exposure for the seal materials in contact with the liquid phase of the product. These materials are prone from getting damaged by this liquid exposure where materials just being exposed to the product vapours are less likely to get damaged. The liquid contacting seal materials is known to result in compatibility problems especially when the product stored has a high content of aromatic hydrocarbons such as Benzene or Toluene.
CTS30, liquid mounted compression plate seal:
Since more than a decade CTS supplies a seal based on stainless steel compression plates penetrating the liquid, being backed up by a vapour and liquid tight PTFE (Teflon®) vapour barrier. The main advantage of this seal is that all materials used are 100% resistant against all known aromatic hydrocarbons and chemicals while being liquid mounted.

Installation
CTS is capable of installing any seal on your
tank, but our extensive drawings and installation
manuals will facilitate you to have either your
own or contractor staff install the seal and, if
applicable, the integral foam dam as well. The
advantage of having your own (contractor) staff
installing the system could be significant, reducing
travelling and lodging costs. Experienced CTS supervision
is available upon request.
Materials, selection
Not just the design of the seal is
important for its performance. Correct material
selection might be even more important to
ensure a long term adequate performance for any
seal. In this respect one also has to realise
that fabrics will be difficult to inspect and
malfunctioning seals could represent a hazard,
while still mechanically sound. Materials have
to withstand the stored product, ozone, sun
exposure and rain water contact. CTS is able
to give you a profound advise on the optimal
combination of materials, resulting in an economic
seal design able to deal with the harshest
conditions. Seals can be manufactured in a wide
variety of materials, including different grades
of stainless steel and polymer materials. This will
make our seals suitable for processes with 100% aromatics or
aggressive chemicals. |
