Plant Solvent Recovery Unit and Chemical Tanker Loading Station Upgrade

Trainer, Pennsylvania

Roux Associates performed an options analysis, detailed design, and permitting support for upgrading an under-performing 1960s era solvent recovery unit (SRU) associated with a plant-wide vapor recovery system (VRS). Options analysis tasks included: identifying feasible SRU upgrade or replacement options; investigating possible SRU and process upgrades to reduce VOC loading; and detailed engineering economic analysis.

Roux Associates recommended abandoning the existing SRU and modifications to the VRS were proposed to accommodate a vapor compression storage/nitrogen blanketing system that eliminated VOC emissions, saving the client tens of thousands of dollars annually in solvent replacement and compliance costs. VOC banking credits (80 tons per year), were proposed to finance a significant portion of the upgrade.

Roux Associates also performed conceptual, detailed design and construction management services for a nine (9) station chemical tanker truck and railcar loading/unloading station upgrade project as required to meet OSHA HAZOPs requirements. Tasks included: detailed site surveying; defining station functional requirements; coordination of clearances with the railroad utility; and preparation of detailed plans and specifications for loading station upgrade. Detailed design activities included: specification of retractable loading platforms, design of foundations, piping, pumps, loading arms, controls and instrumentation.
