High performance cold flow improvers

Cold temperature can be a serious threat to the trouble-free use of middle distillates. BASF's KEROFLUX^® series offers tailor-made solutions to improve the low temperature performance of diesel, heating oils and marine distillate fuels helping to ensure the continued operation of equipment when temperature drops.

Middle Distillate Flow Improvers (MDFIs)

MDFIs enhance the basic cold flow properties like CFPP (Cold Filter Plugging Point) and PP (Pour Point) of diesel, heating oil and marine distillate fuels. MDFIs are low-molecular weight olefin copolymers in organic solvents. The copolymers have a hydrocarbon backbone, allowing co-crystallization with the n-paraffins, and polar side chains which block further crystal growth.

Wax Anti Settling Additives (WASA)

WASAs reduce settling of n-paraffins during storage at low temperatures. WASAs are always used in combination with MDFIs and often also improve the efficiency of an MDFI leading in reduced overall additive costs.

Wax Anti Settling Flow Improvers (WAFIs)

WAFIs are finished formulations of MDFI and WASA. They are an optimal solution for customers with limited number of additive tanks and/or injection equipment.

Lubricity Additives

Diesel fuels with sulfur levels below 500ppm may exhibit insufficient lubricating properties, causing increased wear and injection pump failures. KEROKORR LA^® lubricity additives improve the lubricity of low and ultra-low sulfur diesel fuels.

Antistatics

KEROSTAT^® antistatics (metal-free) increase electrical conductivity of fuels. They can be used in storage tanks, pipelines and during switch-loading to improve safety when handling flammable liquids.

_{Cetane Number Improvers}

KEROBRISOL^® cetane number improvers improve the combustion of diesel fuel. The treat rate depends on the cetane number of the unadditized fuel and the cetane number increase to be achieved.

H₂S-Scavengers

KEROFINE^® H₂S scavengers irreversibly reduce the H₂S-content in liquid fuels to a level that allows safe handling and transportation.

Antioxidants for Middle Distillates

KEROBIT^® grades increase the oxidation stability of liquid fuels. Specially adjusted grades to improve the stability of biodiesel (e.g., FAME: fatty acid methyl esters) are also available.

Metal Deactivators

KEROMET^® metal deactivators are used to bind traces of metals in fuels and prevent fuel oxidation, polymerization reactions and gum formation.

Multifunctional Stability Improvers

KEROPON^® stability improvers prevent gum formation, sedimentation and discoloration in diesel fuels containing unstable components.
