Pharma Company Detecting Natural Gas Leaks in Boiler House A pharmaceutical client determined they needed a natural gas leak detection and isolation system for a utility building based on a PHA recommendation. aeSolutions installed a combustible gas leak detection system to shut off the gas supply to the boiler, bringing the facility into compliance with the safety program requirements. Challenge A global pharmaceutical company’s corporate standards mandated a local manufacturing site install a combustible gas leak detection system in its boiler house to mitigate risk to personnel and equipment. The client needed the ability to detect and isolate gas leaks within a utility building containing multiple large natural gas-fired boilers to lessen the risk to personnel and reduce the potential for extended production disruption due to significant equipment damage. Solution aeSolutions designed and provided an FM approved industrial fire alarm and gas detection system to automatically isolate the main natural gas feed to the building when a leak is detected. aeSolutions also provided detector placement consulting services based on the physical location of potential leak sources. Delivered: • FGS 1300 fire alarm and gas detection/isolation system • Automatic isolation valve installed in natural gas supply line • Eight point gas detectors • Detector placement services Results The client now has an industrial grade system for detecting and isolating a release of natural gas, reducing the risk to personnel and equipment, and complying with their corporate safety program requirements.

Achieving a High-Risk Systems Overhaul on an Accelerated Schedule When TGES America, Ltd. needed a critical overhaul of the complex control system and instrumentation for the central utilities plant (CUP) of a specialty materials manufacturing plant, they turned to aeSolutions, a Siemens Solution Partner. Subsequently, due to the need to complete the project four months early, the planned cold cutover to the new systems had to be done as a hot cutover without disrupting production. TGES America, aeSolutions, and Siemens made it happen, much to the delight of the customer. Challenge Unreliable, legacy controls disrupting production, undermining customer trust, and triggering financial penalties. Solution Engage an expert partner to design, engineer, and install fully modern and ultra-reliable systems for CUP controls and monitoring. Results Improved margins and a repeatable reference model for TGES America — with reliable plant utilities and customer trust restored. Previous Story Next Story

The architecture or voting arrangment used in the field instrument or final control element of a safety instrumented system (SIS) to reach a certain safety integrity level (SIL). Voting logics include one-out-of-one (1oo1), 1oo2, 2oo2, 2oo3, etc. For example, a 2oo2 voting logic indicates there are two protective devices/instruments in a system and both devices (two-out-of-two) are needed to properly shut down the system or mitigate the hazard. 1oo2 indicates that only one of the devices would be required to properly prevent the situation from occurring.

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.
