Advanced Process Control (APC) solutions are recognized as a process industry best practice and proven investment opportunity in many industries, including oil refining, petrochemicals, chemicals, plastics, polymers, air separation, pulp and paper, solids and drying, building products, life...

The standard way of testing a process causes the configuration and tuning of the PID control system for the process to be embedded in the model developed for the Model Predictive Controller (MPC). New technology has become available that can be used to interchange the independent variables with the...

The cracked gas compressor (CGC) is still the most critical unit in the entire ethylene production facility. Its energy demand and potential plant run length, linked to its volumetric flow, molecular weight, pressure ratio and associated contaminant removal, is a major design element within the...

Significant improvement in product quality, energy savings and profitability of operations in current day process industry can largely be attributed to the model-based control. Key component in such model-based control algorithms is fidelity of the process model. However, along with the time,...

Please note: sound does not begin until approximately 30 seconds into the presentation. Typically mathematical models of physical and chemical processes are large and complex because of complications and nonlinearities of physical processes. The importance of mathematical models is evident for...

Magnetic bearings in turboexpander have become the standard for the installation in gas processing and ethylene plants; there are areas of the design that are challenging to the designer for each application. This paper begins with a review of magnetic bearings, the components and how they operate...

A battery design is being evaluated which is particularly useful for larger battery applications such as in PHEV and electrical grid applications. Preliminary studies validate the approach. Parametric studies are discussed which define performance curve.

Introduction Environmental concerns and dwindling world petroleum reserves have generated great interest in producing transportation fuels from bio-renewable resources. In this work, we investigate catalytic deoxygenation of free fatty acids (FFAs) [1] to produce linear hydrocarbons for second-...
