A HAZOP study is a highly disciplined procedure aimed at identifying how a process may deviate from its design intention. This method is able to distinguish between hazard (any operation, that could cause a catastrophic release or that could result in harm to workers) and operability (any operation within the project that could cause a plant ...

We at Kawasaki have proposed a "CO 2 free H 2 chain" using the abundant brown coal of Australia as a hydrogen source. We developed the basic design package and finished the Front End Engineering Design (FEED) in 2014. There are not only the hazards of the processing plant system, but also the characteristic hazards of a hydrogen plant system.

In a HAZOP (Hazard and Operability) study, a package (or a facility) is broken down into 'nodes' on a 'PID'. Each node will be examined under the direction of a number of guidewords such as high pressure, low pressure, low flow, high flow, no flow, reverse flow, etc. Some guidewords will become specific to each system or team.
