Oil and Petrochemicals

Particle size is a very important parameter in the petrochemical industry.


And how particles are measured becomes a core issue here. Bettersize laser particle analyzer is a very professional instrument for the analysis of particle size. Laser particle size tester produced by Bettersize Instruments Ltd meets the international standard with high accuracy and repeatability.


Bettersize laser particle size analyzer wet dispersion system can help you to detect:
Catalysts: including the research and quality control of catalysts. This is its main application in oil refineries and catalyst plants.
Flue gas: it can analyze the particle content and distribution of flue gas in the front pipe of flue gas turbines, ensuring safe operation.
Carclazyte: lubricant additive.
Emulsified liquids: the particle size determines the stability of emulsified liquids.
PVC, phenylethylene and ABS: quality control and research of raw materials and products.
Chemical fibers: quality control and research of raw materials and products.


A fine example of particle size being used to good effect is in the manufacture of oil, water and synthetic based drilling muds. Drilling muds are complex suspensions whose formulation is manipulated in order to make them fit for purpose in the oil extraction process from new wells and maintaining oil well operation in established wells. Bettersize particle size testing equipment has perfect particle size distribution test procedure with excellent particle size test method and offers reliable particle size analysis report, which are widely used in the petrochemical industry.


Drilling muds were originally designed to lubricate and cool down the drill bit, which is still their primary role. These days a fit for purpose mud should prevent ingress of fluids and solids into the rock formation. It has to be borne in mind that a different particle size distribution will be required if a particular well has a different geology. In addition the mud should keep the well clear by transporting the cuttings from the production zone.


Finally the mud should stabilise the well and provide enough hydrostatic pressure to stop oil and/or gas escaping as it is being drilled.


Particles in the mud smaller than the pore size of the rock formation bridge the pores whilst they are circulating. This leads to the formation of a filter cake which stops fluids leaving the well during drilling thus stabilising the well. If the particles are too small, they may deeply penetrate the rock blocking the pores and permanently damage the production. In the 1970s Abram, suggested that the median particle size should be a bit bigger than 1/3 the pore size of the rock to prevent blockage. In the ‘90s, Hands subsequently recommended that the bridging properties of the fluid must be selected so that 90% of the particles are smaller than the pore size of the rock. A perfect match of the bridging agent's size would minimize the influx of fluid and particles into the rock. Currently, the ideal packing theory (IDT) originally used on pigment distributions in paint is gaining acceptance as all-encompassing theory. (IDT) can optimise the particle size distribution and indicate the ideal packing sequence which will further reduce fluid invasion and optimise sealing of the well, as opposed to the Abram's rule which only predicts the size of particle required to initiate a bridge.


Particle sizing systems such as the Bettersize products below are ideal to assist in this work.

    Functional redundancy as an indicator for evaluating functional diversity of macrobenthos under the mussel raft farm near Gouqi Island

    Biological traits analysis (BTA) helps to evaluate the effects of different environmental variables on the traits-based functional composition of macrobenthos. However, research on functional traits of macrobenthos under mussel farming is limited. We investigated the spatial and temporal response of the benthic system in terms of taxonomic and functional diversity to environmental variables of farming and natural stressors resulting from suspended mussel farming near Gouqi Island of eastern China Sea. The functional traits of macrobenthic assemblages under mussel farming were characterized by “medium adult body size”, “vermiform body form”, “high flexibility”, “infauna”, “semi-motile”, “gonochoristic”, “surface deposit-feeders”, “carnivores”, “semi-motile burrowers”, and “tube-dwellers”. Functional redundancy was stable in response to mussel farming stresses among seasons, whereas species diversity showed efficient to evaluate natural variables. Functional diversity was significantly affected by farming stressors rather than natural variables, Further analysis using multivariate methods together with continuous monitoring were highlighted to evaluate the impacts of mussel farming. Our results reinforce the importance of macrobenthic species and functional traits analysis to evaluate human stresses driven impacts in offshore ecosystems. By analysing the environmental variables with different sources, independently, we concluded the main effects of human pressures on macrobenthic community. Such distinction could be particularly effective to isolate variable environmental descriptors and evaluate their effects on functional diversity, making the current approach promising for the evaluation of ecological effects of anthropogenic stressors in aquaculture areas.

    Degradation characteristics and utilization strategies of a covalent bonded resin-based solid amine during capturing CO2 from flue gas

    DOI: 10.1016/j.seppur.2023.125621 Read Article Go logo
    China University of Petroleum | 2024

    In this study, various types of degradation as well as attrition which are possibly encountered in a circulating fluidized bed temperature swing adsorption (CFB-TSA) process, were conducted experimentally to evaluate the stability of a resin-based solid amine sorbent. Other characterizations methods, such as elemental analysis (EA), Fourier transform infrared spectroscopy (FTIR) etc. were applied to further reveal the degradation mechanisms. The results showed that thermal degradation occurs from 140–160 °C due to the decomposition of amine group. The CO2-induced degradation occurs from a higher temperature of 160–180 °C accompanied by the production of urea. Hydrothermal stability is good below 130 °C, but the ionic impurities in steam crystalized on particle surface can accelerate the degradation. Oxidative degradation is the most harmful, which starts at a lower temperature of 70–80 °C with the formation of aldehyde. The existence of H2O in atmosphere can alleviate the oxidative and CO2-induced degradations. The employed sorbent has a very low attrition index of 0.05, which is 1–2 orders lower than typical commercial fluidized bed catalysts. Based on the results of stability evaluation, some design suggestions for proper utilization of this sorbent or other similar resin-based sorbents have been provided in an industrial CFB-TSA process.

    De-branching of starch molecules enhanced the complexation with chitosan and its potential utilization for delivering hydrophobic compounds

    DOI: 10.1016/j.foodhyd.2023.109498 Read Article Go logo
    Shihezi University | 2024
    The current study aimed to prepare the complexes between debranched-waxy corn starch and chitosan polymers (DBS-CS), and then investigated their corresponding structural characteristics, rheological property and potent application in Pickering emulsion. The results indicated that the existence of chitosan significantly inhibited starch short-range molecular rearrangement for all DBS-CS samples, which was manipulated by both debranching treatment and chitosan content. Interestingly, this is the first study to reveal that the outstanding peak at 1.8 ppm in 1H NMR spectrum for sample DBS-CS was gradually shifted towards a lower-field region following an increased chitosan content. Moreover, the debranching treatment shifted the crystallinity pattern from A-type to B-type and the relative crystallinity of DBS-CS decreased gradually with the increased content of CS. All samples had a pseudoplastic fluid and shear-thinning behavior with an enhanced shear resistance following the complexation. The DBS-CS was applied in a Pickering emulsion for showing a greater emulsifying stability and a lower gel strength than native NS-CS prepared emulsion. Importantly, the encapsulation ability of curcumin in the DBS-CS emulsion was significantly improved, followed by an increase of 15.45% for its corresponding bioavailability compared to the control. Therefore, this study might highlight a potential carrier for delivering the bioactive substances in a green pattern.

    Heat-induced aggregation behavior of wheat gluten after adding citrus pectin with different esterification degree

    DOI: 10.1016/j.foodhyd.2023.109420 Read Article Go logo
    Gansu Agricultural University | 2024
    Wheat gluten aggregation during heat treatment is beneficial to the final quality of gluten-based products. Exogenous pectin can affect gluten aggregation. However, the effect of pectin with different degrees of esterification on the heat-induced aggregation behavior of gluten and its possible mechanism are still unclear. Thus, the heat-induced aggregation behavior of gluten after adding pectin with different esterification degree was studied in this study. When the temperature was raised from 25 °C to 95 °C, pectin affected gluten aggregation and was related to the degree of esterification. Specifically, the results of rheological properties and particle size indicated that low-ester pectin improved the viscoelasticity of gluten and promoted gluten aggregation. Thermal properties revealed that enthalpy of gluten added with low-ester pectin (37%) increased from 92.96 J/g to 95.40 J/g during heating process. Structurally, the fluorescence intensity and surface hydrophobicity of gluten added with low-ester pectin (37%) were lower than those added with high-ester pectin (73%). In addition, low-ester pectin (37%) significantly increased the disulfide bond content (from 15.31 μmol/g to 18.06 μmol/g) and maintained β-sheet content of gluten compared with gluten alone at 95 °C, indicating that low-ester pectin was more likely to induce gluten aggregation. However, scanning electron microscope showed that the gluten added with low-ester pectin (46%) exhibited a denser network structure at 95 °C than that added with low-ester pectin (37%). These results will provide a theoretical base for the regulation of gluten aggregation and the quality of gluten-based products by pectin with different esterification degree.
