| dc.description.abstract | Bubble generator is an alternative technology for bubble
producers. One of many other functions of bubble
generator is as a purification tool. Type of bubble
generator that's used in this research is Jet Column
bubble generator. The diameter of the bubble hole
generator affects the length of bubble life, the length of
the bubble trajectory, the bubble shape, and the
purification process absorption of CO2. The methods
used in the purification process are making a solution 4
KOH molar, making purification tool, installating the
output holes, gas purification process and gas testing
performed repeated three times in each test process.
The output bubble generator hole diameters are 0.08
mm, 0.12 mm and 0.16 mm. The result shows that the
greater the diameter of the bubble hole generator of 0.12
mm makes the length of bubble life shorter, the time is
1,77 s and for the smallest hole diameter of 0.08 mm
makes the length of the bubble life af about 3.21 s. The
hole diameter of 0.08 mm results in the length of bubble
trajectory of 1554.289 mm that is longer than that of the
hole diameter of 0.16 mm. The smaller hole diameter
produces bubbles with an average length of 6.441 mm
and bubble diameter of 1.237 mm. CO2 gas content
decreased from 26.8% to 0.00%, and levels of
hydrocarbon content increased by 5540 ppm. | en_US |
