polymers and surfactants can prevent formation of these networks
by retarding the growth of waxy crystals, thereby producing
numerous tiny crystals. Change
in crystal shape diminishes the ability of waxy aggregates to
intergrow and interlock, resulting in lowering the pour point
of the crude.
can provide a fine coating (single monolayers) and change the
wax crystal surface by adsorption; keeping the entire system
dispersed. This predominately results in an improvement in the
waxes deposition behaviour in the crude oil.
has developed such a range of wax dispersant chemistry, which
has proved very effective in interacting with the wax crystal
formation mechanism. The chemicals work by interfering with
the wax crystallisation process.
has designed a specific paraffins dispersant with anti-sticking
properties: Anticor PA 500.
tests (including flow
loop tests) and
applications have proven that Anticor
PA 500 is effective in significantly reducing
the paraffin deposition.
PA 500 is a synergistic blend of ionic
surfactants, which has an ability to absorb onto bare surfaces
of tubings and equipment making them oleophobic.
