Lessons learned from past failures provide insight and know-how needed toinspect and operate storage tanks reliably Storage tanks are a common sight at many facilities of the chemical process industries (CPI). Tanks are part of our everyday life and they…
After four years of project development and execution, the new PolyFuel unit at Petrobrazi petroleum refinery in Romania has been started-up and is fully functional since April 2019. Based on the PolyFuel technology licensed by Axens (Rueil-Malmaison, France; www.axens.net), the…
The pitfalls in cost estimating that cause project overruns have been well known for decades, yet they continue to plague the CPI When I first started writing this article, I set out to summarize the mechanics of project cost estimation.…
This methodology can be used not only for laminar flow, but also for the complete turbulent flow region In recent decades, the impact of energy costs on the transport of fluids has led to a significant reduction in fluid velocity…
A much-anticipated report by the United Nation’s Intergovernmental Panel on Climate Change (www.ipcc.org) shows there is still a long way to go if we want to limit global temperature rise to 1.5°C and prevent dangerous warming. But the report also…
