Why headers matter
Mixing low-salinity stormwater with high-TDS process drains inflates pumping, chemical, and thermal costs. Separate collection for oily water, sour water stripper bottoms, and brine keeps each treatment train right-sized.
Oil recovery, VOC controls, and biological polishing must precede membrane concentration for most petrochemical effluents. Organics and sulfide species are operational risks for evaporative systems if they slip through.
Once a clean, compatible brine line is established, reject can be concentrated mechanically. Non-thermal evaporation may fit parcels of the flow when steam balancing is tight or seasonal.
Materials selection—gaskets, alloys, and coatings—should reflect chlorides, aromatics, and temperature. Foaming and carryover deserve dedicated instrumentation and operator training.
Document safety interlocks for tank venting, H2S monitors, and confined-space protocols whenever concentrators are added beside tank farms.
