Manufacturers are making decisions all the time about what products to make and how best to make them. And, regardless of whether the products are chemicals, fuels, consumer products, or widgets, those decisions are incredibly important for the company’s bottom line and can make—or break—the business. For example, when manufacturing consumer electronics, planners continually search for the best deals on the different components, manage delivery times, and orchestrate their factories to...

The 28th MACC Meeting and Workshop was a huge success! Held at the Art Gallery of Hamilton from May 17-19, 2016, the workshop featured talks from industry member representatives, MACC professors, graduate students, and researchers from visiting companies and universities. This year's theme was "Addressing Uncertainty in Process Operation and Design" and featured keynote speaker Prof. Paul Stuart from École Polytechnique Montréal.

The chemical process industry is continually striving for greater efficiency, throughput and operability in their plant operations, all while adhering to safety and cost constraints. The processes considered are often on a plant-wide scale, involving several operating units, and involve a considerable amount of uncertainty in terms of the raw material quality, utility costs and product demand. Designing such plants to be flexible enough to quickly ramp up or down production in real-time to... [full story]
The air we breathe consists mainly of nitrogen, oxygen, and argon. These components have various applications in many industrial sectors from food/beverage to energy and healthcare. The separation of these components can be done at extreme cold temperatures, i.e. more than 100 oC lower than the coldest outside temperature ever recorded in the Canadian history. Although the raw material, air, is free and plentiful, such separation processes usually start with an energy intensive step –... [full story]
Synthetic diesel and gasoline have been important sources of transportation fuel since World War II, when Axis forces needed a way to power their fleets after the Allies cut off much of their access to petroleum. Traditionally, synthetic fuels are made from coal which is converted into synthesis gas—a mixture of hydrogen and carbon monoxide that can be produced in a device called a gasifier. Gasifiers are widely used today to produce syngas from not just coal, but biomass, petroleum coke,... [full story]
MACC researchers have developed a new chemical process system that will make it less expensive to produce biobutanol—a biofuel that may play an important role in reducing CO2 emissions by blending into ordinary gasoline along with or instead of bioethanol. For the past few years, MACC researchers have been developing a new process that can produce biobutanol using something called the thermochemical route. “The thermochemical route is different from most other biobutanol processing...

MACC Researchers have released 20 new example simulations for solvent-based CO2 and H2S capture processes in common commercial software packages such as Aspen Plus, Aspen HYSYS, Pro/II, and ProMax.
Solvent-based process for capturing CO2 from major energy conversion processes such as power plants and synthetic fuels processes have been in use for decades and are now experencing even greater interest due to their potential use in mitigating climate change. However, simulating these...[full story]
