“…The cells fixed by 2.5 per cent GA and 4 per cent paraformaldehyde were preserved better than those treated with ethanol/acetic acid. This could be caused by the alcohols in the fixation solutions, which could dissolve the membrane lipids, form large pores in the cell, causing corrosion (Vekemans et al, 2004;Zi ołkowska and Wardzi nska, 2015). The fixation methods applying aldehydes showed medium preservation ability for cell morphology judging from the images in Figure 2.…”

“…- Corrosion of carbon steel used in the petroleum industry for pipelines or tanks is mainly caused by the presence of water, corrosive gases (H 2 S, CO 2 and O 2 ), chlorides and microorganisms. The most common form of corrosion occurs when carbon steel comes in contact with an aqueous solution, for instance, when CO 2 is dissolved in water, corrosive carbonic acid is formed [43][44][45][46][47][48][49]. Sulfolane in the presence of water and air also forms an aqueous solution of sulphurous acid [24][25][26].…”

“…For example, an iron carbonate protective layer can be formed on the surface of carbon steel and low-alloy steels (to 9 wt.% Cr) used in the petroleum industry. However, note that fluid movement or the temperature often break down the FeCO 3 layer accelerating corrosion process [46][47][48][49]. It was found that for the water concentration in the range from 1 to 4 vol.%, a protective layer stabilizes the corrosion rate of AISI 1010 steel in sulfolane at a certain level.…”

Water-Induced Corrosion Damage of Carbon Steel in Sulfolane

Sulfolane in contact with water and oxygen forms acidic (by-) products that are major factors in accelerating the corrosion of carbon/stainless steel. In consequence, water-induced corrosion damage can be a serious problem in industrial systems. Hence, the determination of the corrosion resistance of AISI 1010 steel immersed in sulfolane containing 0 to 6 vol.% water was the principal objective of the study. Evaluation of the corrosion resistance of steel electrodes was performed using a potentiodynamic technique and scanning Kelvin probe microscopy. It was observed that the corrosion products layer that formed on the surface of AISI 1010 steel partially protects it against corrosion in sulfolane with a water concentration in the range from 1 vol.% to 4 vol.%. Interestingly, amounts of water above 4 vol.% cause a break-down of the corrosion products layer and deteriorate the corrosion resistance of AISI 1010 steel as well. Moreover, the relationship between the fractal dimension, corrosion degree of the steel surface and water concentration in sulfolane was investigated. The fractal dimension was determined using 2D grayscale images of AISI 1010 steel registered through a scanning electron microscope. It was noticed that both the fractal dimension and the corrosion degree rose with the increased water concentration in sulfolane.

“…Chemical stability, when used in the technical sense, means the thermodynamic stability of a chemical system. Thus, chemical stability can be defined in closed chemical systems, referred to as internal stability, or in open systems that are in contact with the environment [ 46 , 47 ].…”

Automotive Diesel Fuel Internal Stability Testing with the Use of UV and Temperature as Degradation Factors

2022

Diesel fuel stability can be considered from many points of view, of which the two considered most important are stability in contact with the environment and internal stability. Fuel stability in touch with the environment is often defined as oxidation stability, of which measurement procedures are well developed. The presented paper shows that fuel’s internal stability can also be important. The internal stability of diesel fuel with the local use of thermal and ultraviolet radiation (UV) as degradation factors and fluorescence signals as a probe is presented in this paper. We show that the internal degradation of fuel with temperature use differs from that with UV and simultaneous both factors use. Our study shows that using temperature as a degradation factor introduces significant fluorescence fading. Moreover, the fluorescence signal restores significantly later than the sample stabilizes at room temperature. The novelty proposed based on examination is hybrid degradation and an examination cycle that enables the simultaneous use of degradation factors and fluorescence reading. For this purpose, a dedicated measurement setup of signal control and processing was constructed and programmed. The measurement procedure of the data series for specific wavelength enables calculation of signal shifts that allow the internal stability classification of diesel fuel samples in less than 30 min with the cost of a single disposable capillary probe and one polymer plug. Premium and regular fuel examination results show that internal fuel stability can be related to polycyclic aromatic hydrocarbons (PAH) concentrations and can be modified with dedicated additives.
