[appy1]

Hi there,

I am new to plant design area and I have been assigned task of risk analysis of one of the dryer in our chemical complex. anybody has idea or familiar with risk analysis subject? Is there any free software availbale to perform this task, if it is can you send me link.

Thanks

First you should ask the one who assigned you this task what he expects from you, preferably by providing example studies. You should also indicate that you have no experience with this.

You can only meet the expectations of your client (your boss in this case...) when you know what the expectations are. A good boss would provide you the necessary tools and training to do your job well.

Risk assessments consists of different steps: hazard identification, followed by estimation of consequences and probabilities of the different hazardous event scenarios.

One of the questions would be whether risk assessment should be quantitative or qualitative.

I wish you good luck on finding free software...

I agree with Guidoo that the first question is "quantitative or qualitative". If qualitative, HAZOP or What If Analysis is probably your best bet. If quantitative there are more questions to ask concerning techniques, complexity of the study, and the number of incidents to consider. For qualitative you need "Guidelines for Hazard Evaluation Procedures, Second Edition with Worked Examples. For quantitative you need "Guidelines for Chemical Process Quantitative Risk Analysis, Second Edition, both from the Center for Chemical Process Safety, of the American Institute of Chemical Engineers.

A risk analysis is a matter of life and death and cannot be carried out solely by someone new to the world of process design with only a good book to guide him. The book is just a start. You need to be able to ask the right questions to cover every contingency (risk, if you like). Please ask an experienced process engineer to help you.
