Dynamic simulation of chemical processes
… provides a means for the analysis and design of chemical processes. Industrial interest in dynamic simulation has increased due to the recent increase in concern over plant operability, resiliency and safety. DASPII is an equation oriented simulation package which allows solution of dynamic and …

Intelligent Parameter Adaptation for Chemical Processes
Reducing the operating costs of chemical processes is very beneficial in decreasing a company's bottom line numbers. Since chemical processes are usually run in steady-state for long periods of time, saving a few dollars an hour can have significant long term effects. However, the complexity …

Physical Conditions and Chemical Processes During Single-Bubble Sonoluminescence
… to gain insight into the physical conditions and chemical processes associated with single-bubble sonoluminescence (SBSL), nonvolatile liquids such as concentrated sulfuric acid (H2SO 4) were explored. The SBSL radiant powers from H2SO 4 aqueous solutions were found to be over 103 times larger …

Modelling of physical and chemical processes in the small intestine
Chemical and physical processing in the small intestine is an important step for food digestion and absorption. Having reviewed the literature, a relevant model has been developed which enabled investigation into the fluid flow, mixing mechanisms and delivery of nutrients to the wall of the model …

Automated microreactor system for reaction development and online optimization of chemical processes
Developing the optimal conditions for chemical reactions that are common in fine chemical and pharmaceutics is a difficult and expensive task. Because syntheses in these fields have multiple reaction pathways, a significant number of experiments are required to determine the conditions that …

Theoretical and experimental studies of heterogeneous chemical processes leading to stratospheric ozone depletion
The microscopic chemical mechanisms of heterogeneous reactions involving HC on crystalline ice and nitric acid trihydrate (NAT) are of fundamental interest to physical chemists, because such reactions yield "active" chlorine compounds that are readily photolyzed to yield radicals responsible for …
