Improvement of Liquid Organic Fuel Oils Operational Characteristics with Additives

Abstract

The results of experimental studies into the viscosity of heavy fuel oils mixed with a liquid additive Diproksamin-157 and a solid additive based on dehydrated carbonate water treatment sludge with a concentration of 0.5 wt. % are presented. Experimentally it has been found out that the viscosity characteristics of fuel oil at the addition of Diproksamin-157 showed nearly 20 % improvement, and at addition the carbonate slurry –7 – 10% improvement. In the case of water-fuel emulsion comprising carbon nanotubes the improvement of the rheology oil characteristics to 10 – 25% by introduction of carbon nanotubes water suspension containing 0.82 wt. % into fuel has been observed. However this result at the moment has only basic value as it is not economically reasonable to use carbon nanotubes in such concentration.

The scheme of dosing additives to fuel oil and evaluation of the effectiveness of its implementation at the enterprises of the fuel and energy complex

“…The use of mixers (paddle, propeller, turbine, etc.) makes it possible to most effectively solve the problems of averaging the characteristics of products in tanks and preventing bottom sediments [13][14][15].…”

Methods and Materials of Nanotechnologies for Improving the Boiler Fuel Properties

“…This is due to the fact that there are only two main factors for the existence of additional structure formation: the very fact of introducing nanoparticles with excess surface energy into the dispersed system and the possibility of moving and associating molecules around them due to the liquid aggregate state of the system. The effect of adding small amounts of nanoparticles (including together with other additives that have already proved their effectiveness) can be used to improve the rheological properties of various types of hydrocarbon fuels, contributing to a decrease in energy intensity and production costs in technological processes [15][16][17]. However, the practical use of this effect requires solving two questions.…”

Influence of Nanoadditives on Rheological Properties of Fuel Oil

“…The choice of carbonate sludge as another additive, which the authors investigated, was dictated by their earlier good results on improving the rheological properties of fuel oil in its use [11]. Carbonate sludge is formed in the process of coagulation and liming of natural waters at thermal power plants and, from the production point of view, it is a waste.…”

“…In this paper [11], it was shown that a nonionic surfactant, diproxamine, can be used as an additive to a heavy fuel oil and for dispersing nanoparticles. It is generally used in the petroleum and petroleum refining industry as a non-ionic demulsifier and a paraffin deposition inhibitor or as a demulsifying additive for lubricants, particularly turbine oils [12].…”
