HOW TO READ THIS MODEL

The system, explained.

Produced oil can contain dispersed water that gravity alone may not readily separate. EPA describes electrical treatment as one possible emulsion-breaking approach in field oil processing, distinct from heat treatment. This original static vessel makes broad roles inspectable: an open oil-emulsion feed and three real feed-tube side passages, two open unelectrified grid-region decks, a closed electrical-entry location, an upper treated-oil destination and a lower produced-water destination. Six fixed blue marks suggest a droplet-reading area; they are not moving water or a computed electric field. The browser retains a complete bored shell and closed covers; the poster alone opens its facing wall. No wash-water mixing is illustrated: compare the separate crude-desalter lesson for that refinery role.

Model scope and limits

Original 75-part static upstream oil-dehydration role scene with six actual shell openings, a bored feed closure, open feed tube with three drilled side passages, 28 independent open grid rods, six fixed droplet-reading marks, closed electrical and inspection covers, and four bored display feet. The invented arrangement, spacing, colours and proportions are not a vendor design. No energized grids, electric field, power supply, insulation, voltage, droplet motion, coalescence, water or oil quality, emulsion chemistry, flow, temperature, pressure, capacity, controls, relief, rated vessel or joint, foundation, safe electrical work, vessel entry or service qualification is supplied.

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.

Enter through the bored feed end
The emulsion boundary meets a real end-closure bore. Neither fluid composition nor operating flow is selected.
Inspect the complete vessel
The delivered model keeps inner and outer shell surfaces, six real openings and closed covers. Only the poster sections the facing wall.
Look through the feed tube
Three drilled transverse passages and an open axis make arrival visible. They do not establish balanced distribution.
Compare the lower grid region
One of 28 separate open rods locates a possible coalescence region. It is static and unelectrified.
Compare the upper grid region
The second open deck helps distinguish location and spacing. Its invented pattern does not describe a product or electric field.
Read a fixed droplet cue
This blue mark is fixed in the scene. It is not a droplet trajectory, collision, or water-removal calculation.
Find the closed electrical location
The outside penetration stays covered. No cable, transformer, energized conductor, voltage or safe electrical procedure is shown.
Locate separate oil handling
The upper neck ends openly after a real shell bore. It does not prove outlet quality or a destination train.
Locate separate water handling
The lower neck marks further handling outside the scene, without a level-control or water-treatment design.
Keep access closed
The actual side opening has a separate solid cover; the cutaway is a visual study, not vessel-entry guidance.
