CONSTRUCTION OF LARGE-SCALE ABSORPTION PLANT.
The returns are large. At a cost of $1.50 per 1,000 cubic feet of
plant capacity, a plant to handle 60 million cubic feet per day would
cost $90,000. If only 1 pint of gasoline were extracted from each
1,000 cubic feet of gas the yield per day from 60 million cubic feet
would be 7,500 gallons. The gross income at 20 cents per gallon for
gasoline would be $1,500 per day.
CONSTRUCTION OF LARGE-SCALE ABSORPTION PLANT.
As a result of the experimental work with the plant shown in
figures 7 to 13 a large plant, having a capacity of approximately
60,000,000 cubic feet of natural gas per day, was constructed. This
plant is operating successfully and producing 1.2 pints of gasoline
per 1,000 cubic feet of gas. The gas used in this plant is treated at a
pressure of about 235 pounds per square inch.
Ten absorbers of the vertical type are used in parallel; each one is
30 feet high and 30 inches in diameter. Hollow tile is used as filling
to distribute the oil as it falls through the absorber and comes in con-
tact with the gas. Fourteen vertical heat exchangers are connected
in series with piping so arranged that any one of them can be cut
out of service. Each exchanger consists of an 18-inch pipe, 18 feet
long, containing thirty-one 2-inch tubes. The cold oil passes through
the 2-inch tubes, and the hot oil, traveling in the other direction,
passes around the tubes, thereby providing for an exchange of heat
between the hot and the cold oil. The still consists of a sheet-iron
boiler shell 8 feet in diameter and 26 feet long, with a stone tower
26 feet high. Six pipe connections arranged in T form introduce
live steam into the still.
A view of the absorbers is shown in Plate I, B; the stills, con-
densers, and heat exchangers are shown in Plate I, A. A general
view of the plant is shown in Plate II, A.
At a plant other than the one described above the absorbers con-
sist of 20-inch pipe, 20 feet high, with a flange tapped for 8-inch
pipe at the top and a 20-inch by 6-inch swedge at the bottom, welded
on. One foot above the welded joint of the swedge nipple an 8-inch
collar is welded to the side of tower for a gas inlet. The gas outlet
is through the 8-inch opening in the flange at the top of the tower.
Two feet below this flange six openings are tapped in a ring around the
20-inch tower and in these openings are screwed spray nozzles
pointing downward, their center lines forming an angle about of 300
with the center line of the tower. These nozzles have --inch open-
ings behind ,which are inserted twist drills. The fresh oil is pumped
through the nozzles at a pressure 100 pounds higher than the gas
pressure, resulting in a fine spray or fog of fresh oil being directed
downward against the upward stream of gas through the tower.45
