INEOS Enterprises to sell sulfur dioxide business to Ecovyst

INEOS Enterprises has agreed to sell its shares in INEOS Calabrian, its ultra-pure sulfur dioxide and derivatives business, to Ecovyst Inc. (Malvern, Pa.).  INEOS Calabrian operates manufacturing sites in Port Neches, Texas, USA and Timmins, Ontario, Canada. Completion is expected…

GEA launches meVap® family to electrify industrial heat and accelerate decarbonization

In industrial plants, the biggest climate gains are often hidden in plain sight. Behind every evaporation step, every distillation column and every crystallization line lies a constant demand for heat — and with it, a major opportunity to cut emissions.…

Refiners Pursue Flexibility Amid Economic Headwinds

Petroleum refiners are taking steps to support and increase operational flexibility and business agility as logistical challenges and economic headwinds build, and policy certainty is difficult to find Amid the current economic climate, business agility and operational flexibility have emerged…

Fundamentals of Reactor and Vessel Design

This article provides an overview of the engineering, design and operational considerations associated with reactors and vessels, bridging the gap between theoretical design codes and applied process engineering Pressure vessels and reactors are critical components in chemical processes. Their design…

Customizing Bulk-Solids Mechanical Conveyors for the CPI

For effective mechanical conveying of bulk solids in the chemical process industries (CPI), equipment should be tailored to the specific needs of the solids-handling application The sheer diversity of bulk-solid materials encountered across the chemical process industries (CPI), including agricultural…

Editor’s page: From ‘automated’ to ‘autonomous’

The continued and expanding use of digitalization technologies in the process industries have pushed facility operations from “automated” — featuring distributed control systems, programmable logic controllers, safety instrumented systems and others — toward “autonomous” operations, where technologies like machine-learning, open-software-defined…

Rotating bioreactor scheme accelerates production of high-value products

A team of researchers at Iowa State University (ISU; Ames; www.iastate.edu) have developed a new bioreactor concept that streamlines production of value-added bioproducts at smaller scales by integrating three process steps (fermentation, product extraction and separation) into a single, compact…

Waterless technology uses supercritical CO2 to recycle textile waste

Textile waste is one of the fastest-growing waste streams globally, and there are limited options available to efficiently recycle end-of-life textiles into useful materials. A new recycling approach developed by Renasens (Stockholm, Sweden; www.renasens.com) utilizes supercritical CO2 to recover intact…

Modular, low-cost ammonia-production system is designed for intermittent energy

Ammonia is a critical input for agricultural fertilizers, but NH3 production is plagued by volatile prices, difficult global logistics and high CO2 emissions. A new NH3-production system from the startup TalusAg (Austin, Texas; www.talusag.com) addresses these challenges with a modular…

Molten-salt nuclear reactors take the next step toward industrial deployment

Over decades of experimentation, molten-salt nuclear reactors have been shown to deliver high-temperature heat and extremely efficient electricity at reduced pressures. However, these reactors have yet to make the leap into widespread industrial adoption. Terrestrial Energy Inc. (Charlotte, N.C.; www.terrestrialenergy.com)…
