HOW TO READ THIS MODEL

The system, explained.

In a conventional amine acid-gas-removal arrangement, rich solvent from an absorber is routed to a separate stripper or regenerator. The regenerated lean solvent returns toward the absorber, while an overhead acid-gas stream requires separate handling. NETL's conventional flow also shows an external reboiler, overhead condenser, rich/lean exchanger, cooler and pump. This original regenerator-only concept makes six boundary locations and five open contacting decks inspectable. The deck holes and partial rim markers are invented visual shapes, not a tray specification or calculation. Reboiler draw and vapor return name connections to equipment outside this vessel; no heater, condenser, solvent cycle or complete plant is included.

Model scope and limits

Original invented static regenerator-vessel geometry with 55 named mesh instances, hollow shell/heads, five separate perforated contacting-location decks, rich-feed and reflux boundaries, lean-solvent outlet, reboiler draw/return interfaces, top acid-gas passage, closed drilled access cover and support skirt. Forty-five deck perforations are geometric holes, not qualified tray openings. The poster alone removes a facing enclosure half after the complete Blender master and GLB are saved. No solvent chemistry, heat or mass balance, stripping efficiency, pressure drop, temperature, pressure, vapor/liquid distribution, control, relief, corrosion, material, emissions, foundation, flange/closure rating, H₂S handling, sulfur recovery, safe access or qualified installation. The actual reboiler, overhead condenser, reflux drum, exchanger, pump and acid-gas destination are outside this model.

GUIDED COMPONENT STUDY

Trace the system.

Read each explanation, then focus its component in the explorer. This is a learning route through the model, with no operating or maintenance sequence.

  1. Locate the rich-solvent feed

    An upper side passage identifies the rich-solvent entry from an absorber-side circuit. Feed composition, pressure, conditioning and actual line design are not represented.

  2. Find the upper distribution location

    An open ring and eight separate branch markers identify a possible distribution region. Their shapes establish no metered orifice pattern, wetting or vapor/liquid balance.

  3. Inspect a perforated contacting marker

    This highest deck has nine actual geometric holes and a free rim gap. It is a visual marker, not a qualified tray, selected downcomer or operating hydraulic design.

  4. Compare the lower contacting region

    Five decks are separate selectable objects. Their spacing and perforations do not predict stripping efficiency, pressure loss, foaming or required column height.

  5. Distinguish reflux return

    A separate upper boundary represents returned liquid from an external overhead system. No condenser, receiver, pump or reflux ratio is modeled.

  6. Trace the overhead acid-gas boundary

    The top passage is open in the complete GLB. The acid-gas destination and measured composition are outside this vessel.

  7. Separate two reboiler interfaces

    The lower withdrawal and vapor-return passages are independent. Their relationship is conceptual; no reboiler geometry, heat source or circulation calculation is included.

  8. Locate the lean-solvent return

    The opposite lower passage identifies a lean-solvent outlet toward the wider loop. The model does not establish solvent quality, cooling, pumping or reuse at an actual absorber.

  9. Respect the closed access boundary

    A solid cover closes the drilled access neck in the intact model. Revealing internals in 3D is no entry, opening or maintenance procedure.

  10. Separate vessel from complete plant

    The wall has a central void and drilled side openings. A real treatment system also requires external circulation, acid-gas handling and protection not supplied by this asset.
