Abstract: Example computer-implemented methods, media, and systems for isolating an emergency within process systems of a hydrocarbon processing facility are disclosed. One example method includes receiving a drawing of multiple process systems of a hydrocarbon processing facility. A respective identifier is assigned to each of multiple drawing vectors, where each of the multiple drawing vectors corresponds to a respective component of the multiple process systems. The multiple drawing vectors are coded based on the assigned identifiers. One or more drawing vectors connected to a location of the emergency are determined from the multiple coded drawing vectors. One or more connections between the one or more drawing vectors and the location of the emergency are identified. A first isolation valve for isolation of the emergency is determined from one or more isolation valves corresponding to the one or more connections. The first isolation valve is provided for the isolation of the emergency.
