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.
TotalEnergies studies Moroccan project to export green ammonia to Europe
TotalEnergies will study plans for a renewable energy project to produce hydrogen and ammonia in Morocco for delivery to Europe, which is seeking to increase use of the fuels as part of its energy transition.
Sumitomo Chemical begins study to optimize operations at Keiyo Ethylene
Sumitomo Chemical has made a proposal to Maruzen Petrochemical Co., Ltd., its JV partner in Keiyo Ethylene Co., to reduce offtake quotas for Sumitomo Chemical products at Keiyo Ethylene.
BASF invests in increasing production capacity of Neopor® at Ludwigshafen site
BASF is strengthening its styrene value chain at its Ludwigshafen site by expanding the production capacity of Neopor® by 50,000 tpy. This increase is aimed at meeting the growing market demand for the grey insulation material. The start-up of the new production facilities is scheduled for early 2027.
Vopak Energy Park Antwerp starts market consultation for ammonia storage
Vopak is launching a market consultation for the storage of ammonia at its Vopak Energy Park Antwerp site in Belgium. The market consultation aims to gauge market interest and to gather detailed insight into customer demand. Vopak Energy Park Antwerp intends to finish the currently ongoing pre-FEED study by the end of 2024. Subject to market interest and a positive FID the start of operations is currently foreseen in 2029.
