From what I have studied previously HAZOP basically deals with process related hazards whereas HAZID deals with non or other than process related hazards like facility hazards etc. HAZOP is mainly equipments or pipelines, whereas HAZID takes the facility as a node. HAZOP is on the internal of equipments and HAZID is on the external. Hope that helps.

Kasri,

HAZOP (Hazard and Operability Study) is a risk analysis tool which is used to identify abnormalities and its causes and consequences in more complicated or comprehensive processes or operations or in simple words, to avoid hazardous unwanted incidents which may give rise to operability problems and may be significant in terms of damage to life, environment or property.

HAZID (Hazard Identification) is a general risk analysis tool for early identification of hazards or threats, where the purpose is to identify possible unwanted incidents within a discipline, operation or area. These possible incidents are classified with respect to consequences and probability. Measures are then implemented in order to reduce the risk to an acceptable level.
