Acronyms & Terms Glossary <- More Definitions Lower Flammability Limit (LFL) The concentration of a combustible material in air below which ignition will not occur. Mixtures below this limit are said to be "too lean". It is often referred to as the Lower Explosive Limit (LEL). Lower Flammability Limit (LFL) concentrations are considered for endpoint distances during facility siting studies or consequence modeling conducted by aeSolutions' experienced modelers. Modeling helps companies identify the flammable and/or toxic consequences and impacts to receptors due to a chemical release.

Advanced Regulatory Control - ARC Enlisting More Variables aeSolutions process control specialists solve problems with Advanced Regulatory Control (ARC) when single variable PID control is not adequate. Cascade, feed forward, ratio, Smith predictor, and override controls are standard methods to include an additional process variable in PID loops to compensate for process dead time, or non-linearity. Multivariable and model-based controls are employed for more complex process automation challenges encountered in chemical plants and refineries. aeSolutions helps the client's process engineers take advantage of the multivariable control capabilities found in the latest generation of DCS systems. These offer real time performance with multivariable models available at the controller's function library level. Automation Services Previous Next
