Best practice guidelines for selecting types of compressors
This article discusses the best practices for selecting compressors for different applications in refining, petrochemical, chemical and carbon capture plants.
Prompt engineering: Extracting operational excellence knowledge from AI—Part 2
Prompt engineering elaborates precise instructions to guide large language models towards generating specific, desired outputs, and offers significant potential for optimizing processes, solving complex problems and improving operational efficiency in refineries and petrochemical plants. In Part 2, the practical applications of these advanced prompt engineering techniques in various aspects of refinery operations will be explored. Examples include key areas where RAG implementation with specific plant information would be highly beneficial.
Utilize a process simulation digital twin to optimize condensate yield
With the aim to maximize profit, and contribute to sustainability targets by reducing greenhouse gas emissions, ADNOC Sour Gas has optimized condensate hydrotreater operation by adjusting Reid vapor pressure, which resulted in maximizing condensate yield. This article is a case study on using a process digital twin to optimize condensate yield.
Consortium to launch world's first commercialized PET bottle using bio-paraxylene
A partnership consisting of Indorama Ventures, Suntory, ENEOS Corporation, Mitsubishi Corporation, Iwatani and Neste will launch the world’s first bio-PET bottle for commercial scale, made from ISCC+ certified bio-paraxylene.
Consortium introduces world's first pharmaceutical bottle partially made with wood-based plastics
UPM Biochemicals, Selenis and Bormioli Pharma have partnered to produce the world’s first pharmaceutical bottles made from partially wood-based polyethylene terephthalate (PET).
Thermal decomposition of particulate mercury sulfides in petroleum—Part 2
Traces of particulate mercury sulfide (HgS) in stabilized crude oils transform to elemental mercury below 400°C in refinery distillation units. The authors evaluated this transformation and measured reaction rates and activation energies in crude oil and Hg-spiked mineral oil, using glass vessels at atmospheric pressure and a microunit at 1,000 psig.
Needle coke and synthetic graphite: Advance performance through technology application
This article looks at the global graphite market and future demand. In turn, it details the author's company's proven delayed coking technology through conventional and two-step processes to produce carbon precursors for synthetic graphite and needle coke for graphite electrodes.
Examination of design temperature allowance on creep range piping
This article delves into the effects of providing standard design temperature allowances for piping systems operating in the creep range. The aim of examining this practice is to enhance the understanding of its implications for pipe engineering.
SMR feed effluent hairpin exchanger: Once upon a time—An unusual thermal mix-point failure—Part 1
This article presents a review of a failure that happened in a hairpin heat exchanger type on the shell side in a hydrogen (H2) reformer unit. This mechanism was not identified during the design phase and led to a failure after only two years of operation. This article also reviews the situations encountered during the design stage and how they affected the material selection.
Refinery/petrochemical makeup water treatment: A general guide for technical personnel—Part 3
A very important—and sometimes overlooked—unit operation within hydrocarbon processing facilities is makeup water treatment for steam generators and other processes. Many cases have been documented in which makeup system upsets have led to boiler tube failures that partially or completely shut down unit processes. The three parts of this article (August, September and October 2024) serve as a guide for those employees who may be on a steep learning curve when it comes to makeup system understanding.
