Saudi Gas Plant Chemical Store: Class 8 Corrosive and DG Containers

A gas processing operator in Saudi Arabia needed a chemical storage compound for a mixed inventory: Class 8 corrosives alongside other reagents. Corrosive storage and the wider inventory each carry their own segregation requirements, and the hard part is segregation: incompatible classes cannot share a containment system, so the compound had to be laid out so a spill in one store could not reach an incompatible class. On top of that, the Gulf's high-ambient heat and high salinity attack a store that is not engineered for it. On a processing plant, a store that fails inspection sits on the safety case and the environmental approvals.

SCS built the compound from two configurations: corrosive storage for the Class 8 substances and chemical storage for the wider inventory. Each store had chemical-resistant bunding sized for spill containment, ventilation calculated for its contents, IEC 60364 electrical with hazardous-area provisions where the classification required, and a placarding schedule to the operator's hazardous-materials standard and the IMDG and UN class system. The enclosures were corrosion-coated for the Gulf environment. The layout was the engineering: incompatible classes sat on separate containment with the required segregation distances. Built to the QA in our manufacturing process, each store shipped with its compliance pack and was positioned to the segregation layout on site.

The compound was signed off on the first inspection, entered against the plant's DG register and safety case on the strength of the factory compliance packs. Because segregation was engineered into the layout rather than negotiated at inspection, there were no remediation lots and no repositioning after delivery. The chemical-resistant bunding and calculated ventilation matched each store to its contents rather than a generic rating, and the corrosion system was specified for the Gulf rather than retrofitted. The result is a containment system that is defensible on the safety case, delivered on one compliance envelope.
