Additive dosing for fuels

Cleaning, corrosion protection, stable lubrication, or temperature resistance–additives can be fed to fuels such as gasoline, diesel, or kerosene. They ensure fluidity, improve knock resistance, optimize combustion, or modify cold properties. The fuels are thus expanded and can, among other things, also meet the ever-growing environmental requirements. In addition, these additives can also have a positive effect on the performance and the maintenance of the vehicle. Their use can also reduce fuel consumption and save on expensive repairs.

Benefits of LEWA pumps in the dosing of fuel additives:

LEWA supplies both diaphragm metering pumps and process diaphragm pumps for additive dosing in fuels. These have the following advantages:

  • Hermetically tight: No leakage to the outside, contamination of the highly sensitive additives is thus prevented.
  • Safety: Worldwide ex-protection regulations can be met
  • Use of stainless steel: Non-filterable chloride content in the fuel requires stainless steel, as any other material would be destroyed.
  • High metering accuracy: The flow can be precisely adjusted to the required flow rate and thus guarantees a high metering accuracy according to the specifications.
  • Wide product portfolio: LEWA offers a variety of different pumps suitable for fuel additive dosing. This means that the optimal solution can be found for every application..

Background

Additives - indispensable in everyday life.

Since Euronorm 4, fuels must be environmentally friendly. Additives for fuels are an optimal solution. The main focus is on gasoline, whereby additives also play a role in kerosene for aircraft. Up to 150 different additives can be dosed to the fuels.

One of these additives is the flow aid vinyl acetate. It is often used for biofuels E5 or E10. Its ethanol content has an increased viscosity due to esterification. This must be considered especially in the case of external temperature influences. In winter, the viscosity of the fuel may become too high and vinyl acetate must be added to ensure the engine's running characteristics even in cold temperatures.

Another example of additives are anti-knocking agents. These reduce the knocking of a fuel-air mixture, which can occur in the event of premature ignition. The anti-knocking agent increases the amount of product necessary to ignite a fuel-air mixture and thus prevents premature ignition and thus the overheating and destruction of the engine.

A relatively new additive is urea, which is intended for low-emission diesel engines. The aqueous solution consists of a mixture of high-purity urea and demineralized water and can reduce the emission of nitrogen oxides in diesel engines by up to 90 percent. Nitrogen oxides are produced during combustion in the engine at high pressure, temperature, and an excess of oxygen.

Industries

Pumps and Metering Systems for Distillation Plants and Applications in Refineries

Crude oil must be cleaned, separated, and converted (refined) until the final products suitable for sale are made (e.g., gas, diesel, heating oil, lubricants, propane, butane). LEWA supports you with pumps and metering systems, which are used in the refining process during chemical metering. Application with our products are distillation plants, coker, cracker, or visbreaker, for example. Ask our experts for more information!
