Hydrocarbon Processing Xylene-loop scheme for minimized GHG emissions and PX production cost Molecular management, energy efficiency and carbon dioxide (CO2) emissions have become major focuses for petrochemical complexes, including aromatics plants. Investigations of high pressure drop observed in ASU columns The measured pressure drop of columns in air separation units (ASUs) is often reported as being higher than the predicted pressure drop. Advanced cleaner technology: Leveraging tailored solutions for reliability goals Operators at refineries, petrochemical plants and power generation companies are under constant pressure to reduce maintenance and operational costs, boost productivity, minimize risk of unplanned outages and maximize time between overhaul periods. Hydroprocessing catalyst selection—Part 2: Considerations and best practices for catalyst testing Hydroprocessing catalysts are an essential part of the refinery involved in the treatment/conversion of most petroleum fractions, ranging from naphtha to residue. Overcome inflation and supply chain issues in construction Inflation and supply chain disruptions are not new to the construction industry, but the severe combination of these factors and the rapid pace of change driven by the COVID-19 pandemic are unprecedented. Prevent corrosion failures at each stage of design, construction and normal operation Each year, significant economic losses due to corrosion failures occur in the refining and petrochemical industries; unfortunately, many of these losses could have been prevented. History of the HPI: The 1970s: Crises, clean air, plastic bottles and the DCS The 1970s were marked by several historical events that affected not only the hydrocarbon processing industry (HPI) but nations around the world. HP Flashback: Excerpts from the 1970s: Maintenance, optimization, safety and digital technologies Maintenance, optimization, safety and digital technologies Industry Pioneers: Catalysts, polymer processing technology, synthetic lube oils, control systems Catalysts, polymer processing technology, synthetic lube oils, control systems Overview of decarbonization pathways for the oil and gas and petrochemical industries—Part 2 This article is the continuation of an article detailing the seven pathways to decarbonizing the oil and gas and petrochemical industries. Part 1, published in the May issue of Hydrocarbon Processing, covered sustainability and reviewed the following three pathways: green and blue hydrogen (H2); biofuels, renewable fuels and e-fuels; and the circular carbon cycle. Sophisticated analytics build sustainability for renewable diesel projects Anyone studying the development of the hydrocarbon processing industry over the last century will likely admire how far technologies have advanced, particularly considering the tools that were available in the industry’s early years. Uncommon lessons: Shell-and-tube heat exchangers—Part 2 Shell-and-tube heat exchangers (STHEs) are the most common heat transfer process equipment in all types of industrial plants. Editorial Comment The hydrocarbon processing industry (HPI) is filled with unique and innovative people that stive to provide technologies, processes and services to better the industry in which they work. Reliability: Screw compressor volume control options During their careers, most rotating machinery experts have dealt with the selection of advanced screw compressors. Supply Chain: Strategic cost management: Uncover supply chain inefficiencies Controlling costs is critical for any energy company. Firms may spend to grow through acquisition, develop new business, gain market share or invest in new opportunities. Process Control, Instrumentation and Automation: Distillation column DCS control configuration Is there a consensus about a distillation column distributed control system (DCS) control strategy? Much has been written about this topic, covering configuration possibilities, constraints and interacting control considerations. Industry Perspectives: <i>Hydrocarbon Processing’s</i> Mid-Year Update webcast to be held in late June Over the past several years, the hydrocarbon processing industry (HPI) has been engaged in a whirlwind of peaks and valleys. Business Trends: The acceleration of industrial autonomy and its impact on sustainable manufacturing In 2020, the author’s company published the results of a survey that highlighted a significant shift to industrial autonomy, with as many as 89% of companies planning to increase the level of autonomy in their operations. Innovations In a continued effort to serve the corrosion industry, Carboline has launched CarboNext, a program to educate, connect, support and engage with the next generation of engineers and professionals.
