Mechanical integrity storage tanks

The catalyst storage tank failed earlier than expected if the fireproofing insulation was in good condition and the relief valve was adequate for the fire case. Witnesses indicate that several sections of the insulation had either fallen off or heen removed from the tank 2-3 months ago. The insulation had not heen repaired. (Mechanical integrity)...

Mechanical Integrity Programs for Piping, Pressure Vessels, Storage Tanks, and Process Piping... 

The mechanical integrity focus of this section covers stationary existing chemical processing plant equipment and piping. Equipment includes storage tanks, pressure vessels, dryers, heat exchangers, reactors, incinerators, columns, filters, knock-out pots, and so forth. As previously stated, this section assumes the equipment is designed and fabricated to... 

The intent of the mechanical integrity section of the OSHA Process Safety Law is to prevent or reduce catastrophic releases. [1] An equipment classification system is a requirement of the law. Earlier in the chapter, a simple system involving three classes was previously defined. Here are the highlights of that section specifically for pressure vessels and storage tanks. 

Cast iron or steel pumps are recommended and can either be centrifugal, hermetic or those operating with solvent resistant mechanical seals. All vessels and intake lines, marked at the delivery point, should be clearly labelled with the name of the solvent. Regular, recorded inspection should be undertaken to ensure the integrity of the storage tank, pipes and pumps. 

Motiva did not have an adequate mechanical integrity management system to prevent and address safely and environmental hazards from the deterioration of H2SO4 storage tanks.
