Abstract: Termal oxidation and mechanical stability of polyisobutylenes (PIB) with molecular weights of 30 000 and 60 000 in petroleum base (industrial and isoparaffin) and synthetic (polyalphaolifin) oils is investigated. Thermaloxidative stability of PIB solutions was studied using PAPOK-R at the STO Gazprom 2-2.4-134-2007 and PIB solutions stability to mechanical stress was measured by ultrasonic treatment using UZDN-2T. It is found that PIB with molecular weights of 30 000 and 60 000 in the I-20A industrial oil in concentrations of 3,5-9,0 % by weight have high thermal oxidation stability. PIB in PAO-10 oil show minimum thermal oxidation stability. Аn anomaly of viscosity and thermal oxidation stability of the 20A oil and PAO-10 oil mixture containing PIB with molecular weight of 30 000 and 60 000 at concentration of 9 % by weight with PAO concentration of 10 — 30-40 % by weight is revealed. Sonicated PIB solutions stability depending on the composition of the base oil are arranged in series: oil-20A < PAO-10 oil < oil VHVI-4

Abstract: The article considers the possibility of using ΙΙΙ and ΙV group oils of (API) as a basis for the protective liquids for tanks-accumulators of hot water supply in energy companies. The influence of this basis on the thermo-oxidative ability of protective liquids was estimated by the relative change of dynamic viscosity of the compositions after oxidation at the temperature of 80 to 90 ° C and the shear rate of 15-100 s-1. It is found that the protective liquids based on (isoparaffin oil VHVI-4) have the maximum thermal oxidative stability. The influence of the resinous compounds of industrial oil I-20A on the destruction of polyisobutylene in protective liquid is examined. It is shown that the thermooxidative stability of the protective liquid on mixed basis consisting of industrial oils I-20A and PAOM-10 is between those of the protective fluids based on mineral oil and synthetic oi

Abstract: This paper considers the possibility of improving thermal oxidative stability of protective liquids for hot water storage tanks of energy providers by application of anti-oxidant additives. The influence of antioxidant additives on thermo-oxidative stability was evaluated using Folder P device at 140 °C for 6 h by measuring the relative change in dynamic viscosity (at temperatures of 80 and 90 °C). It was found that alkilaminodifenilamin (6PPD) and pentagidroksiflavanon (DHA), reduce the speed of oxidative degradation of PIB in the composition of protective liquid. 0,5 % by weight of these compounds reduce the degree of destruction of the PIB by 68-69 %. A synergetic composition was developed including an antioxidant additive and amine-type alkyl phenol (0,3 % wt. Agidol-1 and 0,2 % by weight. MDS-5), which can increase the thermal oxidative stability of the protective liquid on petroleum basis more than 1,5 times, while maintaining its high antiaerational and anticorrosive properties

Abstract: Protective fluids are widely used in systems of hot water supply to protect from corrosion tanks and batteries, as well as to prevent water from aeration. Modern protective fluids possess high anti-aeration properties but do not meet the increasing requirements to anti-corrosion properties. Effective way to improve anti-corrosion properties of protective fluids is to use corrosion inhibitors. This paper examines the possibility of improving anti-corrosion properties of protective fluids by adding corrosion inhibitors into their composition. Basing on the study of surface properties of protective fluids, the dependence of the sealing properties of inhibited protective fluids from adhesion of their films to the surface of a metal has been defined. The influence of corrosion inhibitors on thermo-oxidative stability of the protective fluid has been studied. The authors recommend to increase thermo-oxidative stability of inhibited protective fluids by using antioxidant additives that allow to obtain a high-performance anti-corrosion material.

Abstract: Industrial oils are the foundation for commercial oils used in industrial machinery, which operating in areas with ambient temperatures -40 °C and lower. Depressants, in particular polymethacrylates, are applied to improve the low temperature properties in lubricating oil. Purpose of this work is to study the possibility of modifying the structure of additives by means of preliminary heat and ultra-sound treatment of polymethacrylates for improvement of their depressant and viscosity properties. Ultrasound treatment was performed at frequency 22 kHz within 10 min, heat-treatment — at a temperature of 80±2 °C within 60 min. Evaluation of the results pretreatment of oil samples with additives after their oxidation was conducted by the method of SRT „Gazprom” 2-2.4-134-2007. Physico-chemical properties of the oils were determined by standard methods. It is shown that additives reduce the pour point of the base oil at 5-7 °C and a kinematic viscosity was increased on average by 10-15 % under optimum processing conditions. Reduction of the additives consumption with pretreatment for increasing the viscosity of the oil and reducing the pour point to the established norms has high practical significance

Abstract: There are no qualified applications of the extracts oil distillate selective treatment, wherein the extracts contain surface active agents, which show antiwear, antioxidant and adhesive properties. The possibility of using solvent refining extracts oil distillate selective treatment as a component of lubricants dispersion medium was investigated. Rheological, low-temperature, oxidation and surface properties of solvent-refined extracts oil distillate selective treatment and its mixtures of mineral base oils were determined. It was established that at concentration 40 % by weight of the extract in a mixture of industrial oil tensile strength, oil separation characteristic, oxidation stability, low temperature properties, adhesion to metal surfaces and lubricity are increased. Greases based on the extracts have a lower cost in comparison with conventional lubricants based on oil mixtures

Abstract: Due to the stringent requirements imposed on diesel fuel, the authors of this paper proposed a method to improve environmental and performance properties of diesel fuels. The paper presents the results of the study of naturally occurring glycerides as detergent-dispersant additives for diesel fuels. The authors have developed a rapid method of determining the effectiveness of antioxidant additives for fuels and lubricants, which is based on the measurement of the optical density of the sample during oxidation in the given experimental conditions. A rapid method of evaluating the detergent-dispersant properties of the fuel based on the determination of the changes of optical density during sedimentation of the pollutant model based on colloidal graphite of grade P-1 (1 wt. % strong). The results showed that the designed additive shows unique surfactant properties at concentrations of 0,001–0,005 % by weight. The additive improves both thermal-oxidative, detergent-dispersant and environmental performance of fuels, because additive molecules contain optimally combined functional groups which creates internal synergies.

Abstract: Protective liquids are applied at power plants to protect the hot water storage tanks against corrosion, as well as to prevent the saturation of deaerated water with oxygen from the environment and its evaporation. Viscosity properties and their dependence on temperature, concentration and molecular weight of the polymer, which is part of the protective liquid are studied. The possibility of using low molecular weight polymers instead of high polyisobutylene as a thickener component is considered. A technique to assess the status of the protective liquid during operation and determine the feasibility of increasing the lifetime of the battery is developed. Options for recycling the discharge protective liquids using adsorbents and selective solvents, as well as by their use as components of lubricants and conservation materials are considered.
