The present invention is Claim a positive control system (1) for container closure integrity (CCI) testing comprising a container and an adapter. The container (3) has a hollow interior (31), an opening (35) and an edge (331) surrounding the opening (35). The adapter (2) has a first coupling structure (21) configured to be connected to a flow reduction holder (4), and a second coupling structure (22). The second coupling structure (22) of the adapter (2) is vacuum tightly glued to the edge (331) of the container (3). The adapter (2) is configured such that the interior (31) of the container (3) is accessible from the first coupling structure (21).

A system and method for training a machine learning gas detection model that monitors gas sensors located at an industrial site. The system and method uses a digital twin arranged to execute simulations of gas leaks using a virtual representation of the physical industrial site and varying simulated wind patterns, gas leak locations and leak rates. The simulations executed by the digital twin train a machine learning gas detection model with time-series gas sensor responses for the simulated gas leaks executed by the digital twin. The trained gas detection model is used in a gas detection system to monitor for gas leaks at the physical industrial site.

A system for monitoring a petrochemical installation is disclosed. The system can include an optical imaging system comprising an array of optical detectors. The system can comprise processing electronics configured to process image data detected by the optical imaging system. The processing electronics can be configured to detect a target species based at least in part on the processed image data. The processing electronics can further be configured to, based on a detected amount of the target species, transmit an alarm notification to an external computing device over a communications network indicating that the target species has been detected at the petrochemical installation.
