Kurita provides tailored treatment concepts for refinery applications

Fouling inhibitors prevent operational failures.

Fouling is a serious problem at oil refineries, which may lead to insecure operating conditions with high production losses. Shortened runtime is a drawback, which requires cleaning procedures and in some cases material exchange. Process conditions, feed qualities and mechanical designs influence the fouling potential and operation. Typical fouling components are waxes, asphaltenes, coke, stable emulsions, inorganic solids or polymers.

Kurita adapts the treatment concepts to your needs to prevent fouling and operational limitations. Our fouling inhibitors have a good thermal stability and can be used as well at higher temperatures, where precipitation, polymerization or coke formation would occur. Asphaltenes are stabilized which avoids precipitation and coke formation. The excellent dispersing power allows you to optimize the heat recovery of the heat exchangers. The viscosity of “varnish-type” viscous polynuclear aromatics and waxes is lowered to keep them in a liquid phase.

Small amounts of oxygen can cause or accelerate polymerisation. Our antioxidants terminate the peroxide radicals which are formed, when oxygen reacts with hydrocarbons. This prevents gum formation derived from thermal and catalytic cracking operations. The antioxidants act as chain-stoppers and stop the initiation or propagation reactions of the radical reaction process.

Kurita provides a complete range of programs consisting of dispersants, oxygen scavengers, stabilizers, antioxidants and metal deactivators. We blend the products, according to your requirements.
