Isentropic effects: Application and simulation
A process safety risk in industry is having unknown problems that are not accounted for.
Quantum leap in chemical plant safety and reliability through mobile technology
The human factor has played a significant role in chemical plant accidents and production loss incidents over the past 60 yr.
Stability evaluation of hot spots in the RDS process reactor
During the end-of-run (EOR) period of the authors’ company’s residue hydrodesulfurization (RDS) process in early February 2019, some hot spots occurred in the catalysts of the reactors.
Ensuring safety in dynamic chemical manufacturing environments
As with all industries, chemical manufacturing is evolving in response to technical innovations, new customer requirements and increased global competition.
Engineering Case Histories: Case 112: Remote failure analysis consulting
An article on “Remote training of personnel”1 is interesting and appropriate at this time of COVID-19. It outlines the difficulties in presenting remote training courses and suggests methods that can help.
Improved measurement of water content in natural gas
Consumers likely imagine natural gas as a stream of pure methane. Those who are closer to the energy industry know that methane is the major component, but there can easily be dozens of other substances making up a sizeable portion of the total volume.
Reliability: Pushing the limit can have unexpected consequences
A prominent manufacturer rediscovered the old axiom, “pushing the limit can have unexpected consequences,” after experiencing many bearing failures in its 40-hp air blowers. These lifetime-lubricated (sealed) bearings had been properly installed on 20-mm shafts, and it can be assumed that premium greases were being used.
Editorial Comment: Maintenance and reliability—A cornerstone of safe and efficient plant operation
Refineries and petrochemical plants are comprised of a series of crucial processes to produce transportation fuels, products and chemicals demanded by the global market. These processes consist of capital-intensive units that must be maintained to provide reliable performance. Failure to adequately maintain these assets can have a detrimental effect to not only operations and profit, but also to worker safety.
Cleaning distillation column and heat exchangers through cutter stock circulation
The Tüpraş İzmit refinery’s largest crude distillation unit (CDU) is designed with a preflash column prior to the atmospheric distillation column.
