Such a problem results in a breakdown of machinery, low efficiency, and very high maintenance costs. Accordingly, herein the nano-ceramic coatings were investigated as a means of protection solution for carbon steel pipes. The coating consists of polyphosphate and silicate co-polymers, deposited using a cold spray atomization process to form a chemically bonded ceramic layer, using a locally developed sol-gel process. SEM and EDXS analyses showed homogeneous coverage of the nanoparticles and a thickness of 100 to 150 µm. Corrosion performances were evaluated in crude oil media for one week, two weeks, and one month, before and after desalting. The coated samples exhibited significantly reduced corrosion rates ranging from 0.08 to 1.66 mm/y, compared to 0.33–3.50 mm/y for uncoated steel, while hardness increased from 130 to 366 Brinell hardness (HB) and adhesion strength exceeded 27 MPa.","PeriodicalId":725,"journal":{"name":"Petroleum Chemistry","volume":"66 8","pages":"947 - 952"},"PeriodicalIF":1.1,"publicationDate":"2026-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149176864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research demonstrates that industrial waste treatment necessitates resource recovery systems based on circular economy principles to achieve sustainable waste management solutions. This approach comprises converting waste materials into valued products, thereby protecting the environment and promoting sustainable practices across industrial operations. The study investigates three separate waste groups resulting from oil and gas industry operations. The research aims to identify the different characteristics of these wastes while exploring their treatment methods, current obstacles, and future potential for treatment improvements. The research explores these waste streams to determine which resources could be recovered and reused.

In a single-stage conversion of carbon dioxide mixed with hydrogen the selectivity toward target liquid products did not exceed 40–55%, with high methane selectivity observed as a competing reaction. When studying the efficiency of the intermediate reaction of CO conversion formed from CO2, it was found that in the temperature range of 260–300°C the process proceeds with the highest yield of liquid hydrocarbons and amines (41–44 g per cubic meter of syngas) with product selectivity reaching up to 75%. At 30 bar, selectivity toward liquid hydrocarbons and amines was nearly insensitive to feed gas flow rate, suggesting that mass transfer limitations play a significant role under these conditions. The reaction produced amines with carbon numbers up to 17, consisting primarily of 1- and 2-alkylamines. Additionally, N-methylalkylamines and N,N-dimethylalkylamines were formed, presumably via hydrocarbon chain growth resulting from CO incorporation into the N–C bond of surface intermediates.","PeriodicalId":725,"journal":{"name":"Petroleum Chemistry","volume":"66 7","pages":"846 - 855"},"PeriodicalIF":1.1,"publicationDate":"2026-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1134/S0965544125602030.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148981328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Emulsification was achieved by mixing distilled water with toluene and heptol solutions of asphaltenes. This asphaltene fraction was found to be enriched in ester fragments and monoaromatic compounds. During standard crude oil deasphaltenization, heptane-soluble compounds became trapped in—or adsorbed onto—the asphaltenes. These compounds were subsequently isolated from the asphaltenes through repeated dissolution of the asphaltenes in toluene and washing in n-heptane, and then characterized. They accounted for up to 20 wt % of the asphaltene mass and consisted predominantly of resins (60–80 wt %). Their structural group composition closely resembled that of the asphaltene fraction responsible for the emulsifying properties of crude oil. We suggest that the surface-active behavior of crude oil arises from resin-like monoaromatic compounds enriched in ester groups, which exhibit a strong affinity for asphaltenes.","PeriodicalId":725,"journal":{"name":"Petroleum Chemistry","volume":"66 6","pages":"612 - 621"},"PeriodicalIF":1.1,"publicationDate":"2026-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148965325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to its good catalytic performance during 1-hexanol oxidation in this study, the 15-VMgO catalyst was doped with different amounts of barium. The prepared catalysts were characterized by inductively coupled plasma optical emission spectroscopy (ICP-OES), infrared spectroscopy, ultraviolet–visible spectroscopy (UV–Vis), and powder X-ray diffraction (XRD). The prepared VMgO and barium-doped (BaVMgO) catalysts were tested for the oxidation of 1-hexanol in the liquid phase using hydrogen peroxide as an oxidant and acetonitrile as a solvent. Within the range of the vanadium loadings studied, the 15-VMgO catalyst showed the highest catalytic activity and hexanal selectivity. Adding barium as a dopant to the 15-VMgO catalyst improved 1-hexanol conversion, with the 2-BaVMgO catalyst showing the best catalytic performance (1-hexanol conversion and hexanal selectivity of 35 and 98%, respectively). Different 1-hexanol to H2O2 molar ratios were studied over the 2-BaVMgO catalyst, and hexanal selectivity was found to be very sensitive to the changes in the molar ratio; the molar ratio of 1.0 was found to be the optimal one. The results indicated that the good catalytic performance was probably related to the synergistic coexistence of pyro- and orthovanadate phases. Moreover, the catalyst was stable for about 5 hours on stream.","PeriodicalId":725,"journal":{"name":"Petroleum Chemistry","volume":"66 7","pages":"869 - 880"},"PeriodicalIF":1.1,"publicationDate":"2026-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148981254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The integration of asphaltene precipitation and deposition is necessary for an accurate forecast of asphaltene blockage throughout the wellbore due to the complexity of asphaltene deposition, which involves many processes operating simultaneously. By creating an integrated model for asphaltene deposition, this study examines the process of asphaltene deposition in an oil well that produces from a Mishrif reservoir in Iraq. The aim of this research is to create an integrated model that combines a thermal-hydrodynamic mechanistic model with asphaltene thermodynamic precipitation and transportation models. The proposed model predicted the asphaltene deposition profile along the wellbore (asphaltene deposition thickness and depth). A sensitivity analysis was performed to examine factors including wellhead pressure, tubing diameter, reservoir pressure, water cut and GOR that influence how severe the blockage is. The suggested model has a notable degree of sensitivity to wellhead pressure, tubing diameter and reservoir pressure (maximum reduction in asphaltene deposition is 1 mm by reservoir pressure reduction) and a lesser degree of sensitivity to water cut and GOR (minimum reduction in asphaltene deposition is 0.1 mm by GOR increasing). Additionally, sensitivity analysis showed that the deposition thickness of asphaltene reduces with decreasing wellhead pressure, tubing diameter and water cut and the thickness increases with decreasing reservoir pressure and GOR. The simulation method presented in this study offers a thorough comprehension of the problems with wellbore flow assurance brought on by asphaltene deposition, which in turn offers helpful insights for enhancing production performance estimates.","PeriodicalId":725,"journal":{"name":"Petroleum Chemistry","volume":"66 8","pages":"940 - 946"},"PeriodicalIF":1.1,"publicationDate":"2026-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149176677","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective: the research seeks to assess KL concentrations that influence oil-displacing effectiveness and additional oil recovery from ranges of sandpack samples. FTIR spectroscopy was used to study the KL chemical composition. The quantities measured are oil recovery factor (RF), total volume of displaced oil (DO2), and the difference between recovery with NaOH and NaOH + KL (RF2–RF1). The experimental method is to prepare aqueous solutions of different NaOH concentrations and KL ratios and inject them into sandpacks at different flooding stages, including primary, secondary, and tertiary flooding stages. The outcomes show that KL ratio up to 0.2 and 1.0 wt %. This leads to a substantial enhancement in oil recovery, where the complete entirety of oils, RF2 increases from 68.85 to 76.78%. Furthermore, the presence of KL facilitated an additional oil recovery (RF2–RF1) of 16.97 to 23.78% on top of that achieved by conventional means. These results indicate the feasibility of using lignin-based surfactants as sustainable and low-cost alternatives in enhanced oil recovery.","PeriodicalId":725,"journal":{"name":"Petroleum Chemistry","volume":"66 8","pages":"933 - 939"},"PeriodicalIF":1.1,"publicationDate":"2026-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149176676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
