When the crude temperature is lowered, the wax crystallises gradually in the form of needles and thin plates. As more wax crystallises, these needles and thin plates turn into 3-D networks causing solidification of the crude; particularly if the crude is very waxy.

Pour point depressant:

Specific 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.

 

Paraffin dispersant:

Additives 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.

Anticor Chimie 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.

Anticor Chimie has designed a specific paraffins dispersant with anti-sticking properties: Anticor PA 500.

Laboratory tests (including flow loop tests) and field applications have proven that Anticor PA 500 is effective in significantly reducing the paraffin deposition.

Anticor 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.
