Agitated Mixing Tank: the Cone-Bottom Light-Oil Agitator (Bell, 1923)
The refinery agitator for washing oil with acid, soda and water: a lead-lined riveted steel tank with a cone bottom, an air line that blows up through the charge to mix it, a spray header for wash water, and draw-offs at the tip of the cone for sludge and finished oil.
Variable: capacity, 160 to 5,000 barrels. Bell's Fig. 87 is 1,000 barrels: 25 ft inside diameter, 25 ft shell, 7 ft 6 in cone, 32 ft 6 in overall.
Source: H. S. Bell, American Petroleum Refining (1923), pp. 195-200. Unknown: plate thickness. Picture: Fig. 87 of the book.

Choose the capacity (160 to 5,000 barrels). Rest the tank on lugs on steel or concrete columns, fireproofing steel ones; the older way of extending the shell down with gussets under the cone is heavy. Fig. 87 stands on concrete footings with a tile drain under the cone tip.

Build the shell and cone
Build the shell and cone
Rivet a cylindrical shell (Fig. 87: 25 ft inside, 25 ft high) onto a cone bottom pitched no more than 4 in per foot from the horizontal for light oils; sludge still runs out at that slope. With a tight lead lining the shell need not be caulked; leave out an occasional rivet so lining leaks show. Not given: plate thickness.

Fit a low roof with relief
Fit a low roof with relief
Use a low globe roof, not the old hemispherical 'gas bag', with plenty of explosion hatches; even 10 % relief area has not always saved a roof. Bell's preferred form (Fig. 89) has two roof segments that lift in an explosion and fall back to smother the fire.

Pipe the air, spray and draw-offs
Pipe the air, spray and draw-offs
Run a 4 in air line down to the cone tip; the blast needs at least 200 to 250 cu ft of free air per minute per 1,000 barrels, at just enough pressure to beat the oil head. Across the top fit a 3 in header with 1 in spray pipes drilled with 1/8 in holes at 2 in centres. At the cone tip fit valved rundown, sludge and drain lines.

Line it with lead
Line it with lead
Weak acid from the washes eats steel, so line it with lead: 8 lb per sq ft on the shell, 10 lb on the cone, or 6 % antimony lead half a pound lighter. Don't just hang it from the top angle: agitation makes a loose lining creep and crack. Hold it with lead-covered steel straps about 8 ft apart, bolted through the shell, and bring the lining out through the draw-off neck.
