Hydrocarbon Processing 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. 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. 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. Sustainability: Staying ahead of environmental, social and governance goals Investing in firms that champion environmental, social and governance (ESG) issues (TABLE 1) has been discussed for decades but is now moving to the forefront of corporate initiatives. Process Controls, Instrumentation and Automation: Reduce maintenance costs by optimizing pressure transmitter calibration intervals Pressure instrumentation is crucial for the functionality and safety of hydrocarbon processing facilities worldwide. Impact of biofeed retrofits, coprocessing on refinery amine units, SWSs and SRUs—Part 1 Diesel with a portion of biologically sourced carbon is being produced at an increasing number of conventional crude oil refineries. Tips to avoid pitfalls in CO<sub>2</sub> capture projects In recent years, growing concern about increasing atmospheric carbon dioxide (CO2) levels has put mounting pressure on governments and on processing industries to curb carbon emissions. Comparing green fuels for marine engines—Part 1 The marine shipping industry, which accounts for 80% of global trade and 3% of annual global carbon emissions,1 must adhere to stringent International Maritime Organization (IMO) goals of reducing total annual greenhouse gas (GHG) emissions by at least 50% below 2008 levels by 2050.2 Sustainability through efficiency: A plan for the refining industry The U.S. Energy Information Administration projects that carbon dioxide (CO2) emissions will decrease through 2050 in Organization for Economic Co-operation and Development countries (OECD), which includes the U.S.1 Safe and sustainable alkylation for the forward-looking refiner In a post-pandemic economy, global governments and industry participants are increasingly committing to meeting climate action targets.
