Today’s tools are often specialized for a certain type of task; however, they often lack the connectivity that would enable the easy comparison and cross-reference of asset information. Engineering tools are well suited for design and build phases, but may be less suited for use in operations and maintenance.
Gas processing, liquefaction, oil refining, bulk petrochemicals and chemicals plants represent a large population of frontline engineers and technical managers. Their professional lives will become increasingly impacted by the growing adoption of disruptive digital technologies and digital platforms.
Since the 1970s, Brazil has been a world reference in automotive biofuels, especially bioethanol produced from sugarcane. In 1973, the Organization of the Petroleum Exporting Countries (OPEC) forced a sharp rise in oil prices, triggering a massive slowdown in the country’s economic growth, which had been going through what was dubbed the “economic miracle,” with growth at an average of 12% of GDP. This study gives an overview of the biofuel sector in Brazil, along with the main business challenges and opportunities in this area.
Significant change is coming to the hydrocarbons industry. Up to 43% of the global conventional polymer production expected by 2040 may disappear due to circular economy (CE) initiatives. In addition, due to the growth in wind turbines and solar panels, and in lightweight composite materials in cars and planes, advanced materials waste is just beginning.
The state of the global engineering, procurement and construction (EPC) industry can accurately be described as “challenging.” Operating in an environment of volatile, uncertain, complex and ambiguous conditions, EPC firms are facing unsustainable levels of stress.

In a typical xylene loop, C8 aromatics are fractionated out of a heavy reformate C8+ aromatics stream and collected in the xylene column overhead. Then, paraxylene (PX) from the C8 aromatics stream is recovered as product—usually by an adsorption or crystallization process—in the PX recovery section.
Ammonia is well known as a fertilizer. However, it is also a potential carbon-free fuel and an excellent solution for storage of renewable electricity, especially if the syngas needed for producing the ammonia is made by electrolysis.
Achieving effective catalyst regeneration requires a process that produces a very high level of heat in a very efficient manner. Over the years, several different approaches have been taken to create this required heat. Traditional steam has been a popular choice, as has heated transfer media. However, these methods have limitations.
