Transporting chemical products across global supply chains is complex and challenging, but data-supported technologies are helping to improve efficiency, sustainability and reliability Materials produced by the chemical process industries (CPI) are used in nearly all global product chains. According to…
Alternating-current (a.c.) induction motors are widely used throughout the chemical process industries (CPI) and other manufacturing sectors to convert electrical energy into mechanical energy to power rotating equipment, such as centrifugal pumps, compressors and fans, as well as other industrial…
Henry Kister shares lessons learned from troubleshooting distillation towers On an assignment to troubleshoot a vacuum tower for a petroleum refinery, my team was tasked to “run simulations to determine why the heavy vacuum gas oil (HVGO) has a very…
Nickel alloys have long been the default choice for demanding applications in the chemical process industries (CPI). A new grade of stainless steel offers an alternative Demanding chemical engineering applications, such as plate heat exchangers (PHEs; Figure 1), tubing, pipes…
Cleaning equipment surfaces is critical for processes involving biological materials to prevent microbial contamination. Clean-in-place (CIP) systems play a key role. In addition to preventing contamination, CIP systems also remove grit, scale and organic matter, which may affect process performance.…
Henry Kister shares lessons learned from troubleshooting distillation towers Construction of new production units has an undesirable byproduct: trash. Sometimes the hard question is— Who will clean? The author was the startup superintendent on a new unit in an olefins…
The guidance provided here can help to mitigate problems occurring in pumping systems used for condensate recovery Condensate recovery is crucial to energy reduction and water conservation in a steam-using plant. It reduces effluent discharge and treatment requirements, as well…
