Facility siting studies are used to ascertain location based risks for a plant and ensure that occupied buildings are located at a safe distance from process units. A Facility Siting Analysis is intended to evaluate the potential hazards and consequences of uncontrolled releases of flammable and toxic substances; to assess their potential for injuring the occupants of fixed and temporary structures on or offsite; to identify existing safeguards; and to determine measures to reduce the risk posed by these potential events. aeSolutions has trained facilitators to execute the hazard recognition and risk reduction process and experienced modelers that apply the appropriate methodology in line with API 752/753 and industry best management practices for Facility Siting. We provide results that allow your site leadership team to allocate resources more effectively to minimize facility siting risks.

Safety Instrumented System is a system of hardware and software controls engineered to perform "specific control functions" in order to prevent or mitigate hazardous events by taking a process to a safe state when predetermined conditions are violated. What and how the system should perform may be determined via HAZOPS (Hazard and operability studies) or LOPA (layers of protection analysis). aeSolutions' engineering specialists will design, configure, test, and install documented Safety Instrumented Systems that verifiably meet the client's Safety Requirements Specifications.

Process Hazard Analysis (PHA) is a process for analyzing hazards with hazardous chemicals. The goal is to recognize potential causes and evaluate the consequences of hazardous chemical releases. PHA studies are the core of process safety and risk management programs. They help companies identify hazard scenarios that could lead to a release of highly hazardous chemicals that can cause negative impact on people, the environment, and property. PHA also is required by OSHA's PSM (29 CFR 1910.119) and EPA's RMP (40 CFR 68) regulations in the US and process safety and risk management regulations around the world. Types of PHAs include: - Hazard and Operability (HAZOP) - What if - What-If/Checklist Analysis - Failure Modes and Effects Analysis (FMEA) - Dust Hazard Assessment - Control System Hazard and Operability (CHAZOP) Acronyms & Terms Glossary <- More Definitions PHA Process Hazard Analysis (PHA) is a process for analyzing hazards with hazardous chemicals.

Enlisting More Variables 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
