Abstract:

The study aimed at availability of petroleum products in Nigeria through the operation of enhanced modular refinery process due to inefficient conventional major refineries. The enhanced modular refinery converts or processes residue product from conventional modular refinery as feedstock to the hydrocracker reactor for viable and desired products such as liquefied petroleum gas, naphtha and diesel. Therefore, twenty Nigerian crude oil types were classified as sweet, light and medium crude oil, and these crude oil types were categorized based on their recovery volume at true boiling point of 3

Abstract:

The vacuum distillation unit (VDU) is the key unit to produce vacuum gas oil and vacuum residue, which has a very important impact on the downstream secondary processing units. The optimization of deep-cut vacuum distillation seeks to improve the yield of heavy vacuum gas oil (HVGO) and its dry point temperature, which is related to the economic benefits of the refinery. In this study, we first established a simple model of a VDU by using the Aspen HYSYS Process simulation software. Then, we built a rigorous model with fast convergence by using the initial values obtained by the simple model.

Abstract:

AbstractTo ensure the optimum performance of downstream processes in a petrochemical refinery, the operation of a vacuum distillation unit (VDU) is critical. It needs to satisfy the yield and quality requirements of the downstream process. Otherwise, it will result in a loss of profitability in the refinery. Hence, it is important to optimise the operation of the VDU to ensure optimum performance. Traditionally, VDU is operated within the design envelope, and its operation condition is fine-tuned based on the operator’s experience. However, such action does not guarantee the optimum performanc

Abstract:

With increasing global energy demand and lower energy efficiency for inverted energy (EROEI) for crude oil, global energy consumption by the O&G industry has increased dramatically in recent years. Moreover, this increased energy has led to an increase in greenhouse gas emissions, which has had negative environmental impacts. On the other hand, generating electricity through renewable resources has become a relatively competitive cost for fossil energy sources in a "cleaner" way. In this study, renewable energy is optimally combined into the refinery, taking into account costs and carbon d

Abstract:

AbstractHydrocarbon processing from extraction to the final product is an important aspect that needs an optimised technology for consumption-led market growth. This study investigated real data from the oil processing facility and analysed the simulation model for the entire crude oil processing unit based on the process system engineering aspect using Aspen HYSYS. The study mainly emphasises the process optimisation in processing the hydrocarbon for the maximum yield of the product with less energy consumption. The investigation also includes a thorough economic analysis of the processing fa

Abstract:

AbstractHardware‐based sensing frameworks such as cooperative fuel research engines are conventionally used to monitor research octane number (RON) in the petroleum refining industry. Machine learning techniques are employed to predict the RON of integrated naphtha reforming and isomerisation processes. A dynamic Aspen HYSYS model was used to generate data by introducing artificial uncertainties in the range of ±5% in process conditions, such as temperature, flow rates, etc. The generated data was used to train support vector machines (SVM), Gaussian process regression (GPR), artificial neural

Abstract:

Abstract This study addresses a critical gap in research on integrated compressed natural gas (CNG) production processes in Nigeria, despite the country’s abundant natural gas reserves and governmental push for CNG adoption. A detailed parametric analysis was conducted on a 25 MMcuft/d modular gas plant using the Aspen HYSYS sensitivity analysis tool to assess the effects of pressure, temperature, and flow rate across the dehydration, sweetening, and compression zones on critical performance indicators. Maintaining feed gas temperatures between 25 and 30 °C in the dehydration zone optimized wa

Abstract This work aims at analyzing the performance of a double-pipe heat exchanger (DPHE) using low concentrated (0.02–0.06 vol%) water, methanol, castor oil and silicon oil based Cu-MXene hybrid nanofluids. Convective heat transfer experiments were successfully performed in fabricated modular double pipe heat exchanger without using any twisted tapes, surfaces and effectively measured various heat transfer parameters such as Nusselt number (Nu), heat transfer coefficient (h), rate of heat transfer (Q), overall heat transfer coefficient (U), friction factor (f), pressure drop (∆P), and the t

AbstractSulfur recovery units (SRU) have an important role in the industrial production of elemental sulfur from hydrogen sulfide, whereas the generated acidic gas emissions must be controlled and treated based on local and international environmental regulations.
