The objective of this HAZOP study review is to highlight the process hazardous deviations, their causes, consequences and safeguards against them. Corrective actions and recommendations are proposed based on this study in order to improve the operability and safety of the facilities. A formal systematic rigorous examination to the process and engineering facets of a production facility was carried out, which mainly emphasizes upon the operating integrity of a system, thereby leading methodically to most potential and detectable deviations which could conceivably arise in the course of normal operating routine,start-up or shut- down. It accommodates the status of recognized design standards and codes of practice but rightly questions the relevance of these in specific circumstances where hazards may remain undetected.  COMMON DEFINITIONS USED IN HAZOP STUDY: 1. CAUSE: The reason(s) why the DEVIATION could occur. More than one CAUSE can be identified for one DEVIATION. COMMENTS: Any remarks to be given to the RECOMMENDATIONS or which, in another way, showed up during the HAZOP study sessions. 2. CONSEQUENCE: The results of the DEVIATION, should it occur. CONSEQUENCES may comprise both process hazards and operability problems, e.g. plant shutdown. More than one CONSEQUENCE can follow from one cause and, one CONSEQUENCE can have several CAUSES. 3. DEVIATION: A way in which the process conditions may depart from their INTENTION. 4. INTENTION: Description of how the process is expected to behave at the STUDY LINE. This is qualitatively described as an activity (e.g. feed, reaction, sedimentation) and/or quantitatively in the process parameters, e.g. temperature, flow rate, pressure, composition, etc. 5. GUIDEWORD: A short word to create the image of a DEVIATION of the INTENTION. The most commonly used GUIDEWORDS are:  NO;  MORE;  LESS;  AS WELL AS;  PART OF;  OTHER THAN; and  REVERSE. The GUIDEWORDS are applied to all the PARAMETERS, in order to identify unexpected but credible DEVIATIONS from the INTENTION. 6. PARAMETER: The relevant parameter for the condition(s) of the process, e.g.:  Flow;  Temperature;  Pressure;  Composition;  Phase;  Level;  Sampling;  Corrosion/Erosion;  Maintenance;  Reaction;  Contamination;  Leakage;  Spillage;  Toxicity  Start-up / Shutdown; and  Others
