Hydrocarbon Processing Managing complexity in engineering and construction projects It is widely accepted that new management methods are needed to curb the frequent delays and cost overruns observed in engineering and construction projects. Sustainable refinery of the future: Versatile, efficient and smart Greenhouse gas emissions occur alongside an inflection point for global refined product consumption. Since the 1850s—when the first oil refineries were constructed—the world has changed dramatically as refined product demand has continued inexorably upward. Sensitivity analysis of a plug flow reactor A sensitivity analysis study evaluates uncertainties in a model’s output based on the changes in the input parameters of the model. Save energy and reduce CO<sub>2</sub> emissions with closed-loop optimization of utilities networks Oil and gas, petrochemical and chemical companies face the difficult challenge of maximizing profitability while achieving aggressive decarbonization objectives set for 2030 and beyond. HP Flashback: Excerpts from the 1960s: Petrochemicals rise in prominence and new know-how in refining processes Petrochemicals rise in prominence and new know-how in refining processes CO<sub>2</sub> energy recycling approach in the petrochemical industries Many industrial processes can generate carbon dioxide from fossil fuels. Recently, these processes have contributed to an average annual release of more than 30 Btpy of carbon dioxide into the environment. Overview of decarbonization pathways for the oil and gas and petrochemical industries—Part 1 This two-part article will cover the seven pathways to decarbonizing the oil and gas and petrochemical industries. Business Trends: Insights from the <i>2020 Worldwide Fuels Refinery Performance Analysis</i> The author’s company recently completed its data analysis for the 2020 Worldwide Fuels Refinery Performance Analysis (Fuels Study). Executive Viewpoint: Maire Tecnimont and the second wave of the circular economy The circular economy has already entered the public’s consciousness, and consumers are increasingly aware of the urgent need to recycle plastic, with the practice becoming more widespread than ever. Circular Economy: Innovative recycling, driving circularity while decarbonizing the petrochemical industry Plastic pollution’s environmental challenges, as well as new government legislation, are having a significant impact on the plastics industry.
