Enhancing Fractional Distillation of Petroleum Through Computational Modeling and Automation

2025-09-01T11:19:37+00:00

The fractional distillation of petroleum is a crucial process in the oil and gas industry, enabling the separation of various hydrocarbon components for use in various applications, such as fuel production, chemicals, and lubricants. Traditional distillation processes are highly energy-intensive, and their efficiency depends largely on the precise control of various parameters such as temperature, pressure, and flow rates. This article explores the application of computer science in optimizing fractional distillation processes through modeling, simulation, control systems, and data analytics. The integration of machine learning, artificial intelligence, and real-time process control offers significant improvements in operational efficiency, safety, and product quality. The article also highlights the future directions and challenges in applying computer science to improve the fractional distillation of petroleum.

Synthesis And Properties Of Kafn-2024 Corrosion Inhibitor For The Oil And Gas Industry

2025-09-26T02:35:05+00:00

The article presents the synthesis, physicochemical properties, and anticorrosion efficiency of the KAFN-2024 inhibitor, developed for protecting equipment in the oil and gas industry from hydrogen sulfide corrosion. The inhibitor is based on urea, formalin, sodium tripolyphosphate, and acrylic acid. Experimental studies include pH measurements at various temperatures, gelation time, density, and gravimetric tests on steels (36G2S, 17GS, St.3) at 120-250°C. Results show 93-98% inhibition efficiency at 100 mg/L concentration. Economic analysis compares KAFN-2024 (25.44 million UZS/ton) with analogs, demonstrating cost-effectiveness. Tables and graphs illustrate the data.

Morphological And Phenological Characteristics Of Fraxinus And Populus Plant Pollens (On The Example Of Navoi City Area)

2025-09-18T20:09:37+00:00

This study investigates the morphological and phenological characteristics of pollen grains from Fraxinus (ash) and Populus (poplar) species in the Navoi city area, Uzbekistan. The research was conducted during the flowering seasons of 2023-2024, examining pollen morphology using light and scanning electron microscopy, alongside phenological observations of flowering patterns. Fraxinus pollen grains demonstrated tricolporate aperture type with reticulate exine ornamentation, measuring 28-32 μm in polar diameter. Populus pollen exhibited inaperturate characteristics with granulate surface texture, measuring 35-40 μm. Phenological observations revealed that Populus flowering occurred earlier (March 15-April 10) compared to Fraxinus (April 5-May 5), with temperature accumulation playing a crucial role in flowering initiation. The study provides essential data for aerobiological monitoring, allergological assessments, and understanding plant adaptation strategies in the arid conditions of Central Asia. These findings contribute to the development of regional pollen calendars and support urban green space planning in Navoi city.

Laboratory tests (gravimetric method at 120-250°C) show KAFN-2024 achieving 93-98% efficiency, comparable or superior to analogs, while costing 37-155% less (25.44 million UZS/ton). Tables and graphs highlight performance differences, demonstrating KAFN-2024's advantages for Uzbekistan's oil and gas sector.

How 3d Printing Is Transforming Architecture: From Complex Forms To Personalized Housing

2025-09-21T21:27:56+00:00

The rapid development of 3D printing technologies is reshaping architecture by offering new opportunities in design, construction, and housing adaptation to individual needs. Additive manufacturing enables the creation of complex forms that were previously difficult or impossible to achieve with traditional methods, while at the same time opening possibilities for the production of personalized housing that reflects specific cultural, climatic, and social contexts. In addition to the freedom of form, this technology provides tangible advantages such as faster construction times, lower material and labor costs, and greater accessibility to innovative housing solutions, making it especially relevant for addressing global housing shortages and urban expansion. Another significant aspect is sustainability, as 3D printing allows the use of recycled or locally available materials, minimizes waste, and reduces the overall carbon footprint of the construction industry. The scientific value of this research lies in demonstrating how additive technologies can transform architectural practice by combining design innovation with economic efficiency and ecological responsibility, offering a comprehensive framework for the future of sustainable architecture while highlighting the remaining challenges of regulation, standardization, and professional training.
