Summary: Twelve crude oil blends were analyzed through TBP distillation and density tests. Four blends followed the additive blending rule, while the other eight showed deviations from the estimated values. Statistical correlations were found between the TBP yields of light and heavy naphtha, as well as vacuum residue, with the molar excess volume of the blends.

Summary: This paper investigates the impact of sodium dodecyl benzene sulfonate (SDBS) concentration on the stability of crude oil-mineral water interfacial film. By constructing different simulation systems and comparing with experimental results, it is found that the number of SDBS molecules per unit area of the film increases with concentration, leading to increased film thickness and interface formation energy. In addition, inorganic ions weaken the performance of SDBS and detrimentally affect the structural strength and stability of interfacial films.

Summary: Studies indicate that sulfur-containing compounds decompose at elevated temperatures, partly through a radical-induced mechanism, and the resulting intermediates exhibit limited stability in the presence of oxygen.

Summary: We enriched bacterial consortia from oilfield samples and found that they have potential for bio-catalytic upgrading of heavy crude oil. Treatment with one bacterial consortium resulted in an increase in saturates fraction, a decrease in aromatics fraction, a reduction in asphaltene content, and an increase in resins. The biotreated oil also showed better recovery of fractions compared to the non-treated oil. The bacterial consortia composition varied with the source and changed over time, with certain bacteria identified as key players in the bioupgrading process.

Summary: The study found that the influence of WTI crude oil price on its production capacity exhibits a non-linear relationship, with price changes depending on transformation variables. Moreover, there are complex relationships between the change rate of the US Dollar Index, the price change rate of WTI crude oil, and the production capacity change rate.

Summary: This work proposes a methodology to predict the interfacial tension of water/crude oils by modeling the composition of crude oil samples using a combined approach of experimental characterization, surrogate molecular representation, and mesoscopic simulations like dissipative particle dynamics (DPD). The study analyzes the influence of different variables on the models, proposes surrogates based on building units with different functional groups, and applies a thermodynamically consistent methodology to obtain the DPD interaction parameters of different chemical building units. The DPD simulations provide predictive values of the interfacial tension in good quantitative agreement with experimental data.

Summary: A series of novel carotenoid-derived non-thiadiamondoids cage organic sulfur compounds (OSCs) were identified from crude oil. Non-polar sulfur compounds were isolated using the methylation/demethylation method and characterized using FT-ICR MS and GC-MS. The cage OSCs were tentatively identified as 2-thiatricyclo[4.4.0.0<3.8>]decanes. These novel OSCs were found to be generated by biological sulfate reduction, providing new clues for the preservation of hydrocarbons in geological environments through sulfurization. The cage OSCs have the potential to be biomarkers for studying sedimentary environments.

Summary: This paper presents a grassroots design of cost-effective and low-CO2 emissions heat exchanger networks for crude oil distillation units (CDUs) to address high energy consumption. The proposed model and algorithm show robustness in solving the global optimization problem. Additionally, an active evolution strategy is proposed to promote structural evolution and improve the tradeoff between economic benefits and environmental impacts.

Summary: This article introduces a novel approach to achieve operational excellence for distillation units, particularly crude distillation units, through tight control of product quality estimated by inferential models. The use of True Dew Point (TDP) curve for model input simplifies calculations and shows potential for better results compared to traditional methods. Validation of inferences against different benchmarks and the application to real laboratory and plant data demonstrate the effectiveness of the proposed approach.

Summary: This study identified the functional compounds in crude oil that contribute to the low salinity water effect during water injection. Acidic compounds with aliphatic nature and asphaltene molecules were found to promote the formation of water-in-oil microdispersion at the interface, crucial for designing waterflood operations in oil reservoirs.
