Conclusions
-
1.
It is necessary to completely exclude the use of bubble-cap plates in planning.
-
2.
In gas-fractionating units intended for preparing hydrocarbon fractions of high purity (97.0–98.0%), it is necessary to use only disk-valve plates.
-
3.
In gas-fractionating plants intended for preparation of hydrocarbon fractions of purity up to 95%, it is necessary to use grid plates.
The use of grid plates reduces the cost of fractionating columns approximately by 30% compared with the cost of fractionating columns with valved plates, which permits a whole gas-separating unit to be made 12–15% more cheaply.
