I think that this whole discussion should revolve around tank certification and re-use.
As we all know, corporations frequently re-use and reassign storage tank for a variety of petrochemical services. Of course, a tank that is perfectly acceptable for one liquid service may pose a very danger when used in another.
Supposedly, the acceptability of the method of storage is evaluated during the HAZOP evaluation that is required by law.
Anyone who has spent time on the Chemical Safety Board website knows that the process chemical industry does not update HAZOP studies and has a woeful record of fires and explosions because of this.
This screwed up federally mandated system of HAZOPs is better than nothing, but sometimes assumes everyone in the room is an expert on everything. Corporations love to fire anyone with more than five years of experience
A better method, IMHO, would be for the AIChE to get off thier dead asses and develop a new system of tankage design regulations for commonly stored chemicals. The new standards could group chemicals and require certain safe tank designs for that group. Safety, corrosion resistance and economy can be considered.
Will the industry do this....???
Can the indusrty make progress and actually develop clear and useful standards that everyone can benefit from ???
We will just hire more MBAs and newbies.....
Rather than having the MBA assign the poor newbie to take design responsibilities that are beyond hs range of experience, a set of AIChE reference standards for tanks would go a long way toward progress and safety for all
