GC Calibration78 Experiment Have been carried out
Standard Gas Cylinder( around 40 exp)
• Real Gas Percentage(±2%):CO2: 74.48%; O2: 17.65%; N2: 7.88%
• Experiment results:CO2: 80; O2: 14; N2: 6
Questions and suggestion:• According to approximation:
O2, N2 are acceptable But CO2 is not!
• Accept this Calibration (which work for us)
• Buying new standard cylinder• Changing method which is not recommended

GC Calibration78 Experiment Have been carried out
Entrance Mix gas( around 40 exp.)
• The exact gases amount in mixture are obtained, BUT:
Questions and suggestion:• The time of sweeping is changed
variously from 3min to 40min (Based on the mixture and the flowrate)
• →Vacuum pump could solve the major part of this problem.Detector’s solid substance need to be sweeping. So the time consumption is inescapable.

Cryogenic Carbon Capture2 Experiment Have been carried out
The experiment took about 1hour.This time consume for:• Chiller cooling• Compressor
pressurizing
Pros:• No leakage have been
recorded in the system.• No water have been
observed after the third condenser.
• Process controller system correctly worked
• Steam generator worked well in the system
Cons and bottlenecks:• Liquid CO2 have been
obtained BUT the separation faced a problem.
• The compressor oil vomiting have been happened in both case.

Cons and bottlenecks:
• Presence of CO2 is completely visible in the purge line:(The intense temperature drop is an evidence as well as GC recordings)

Cons and bottlenecks (Bottleneck):The milestone picture
![Page 7: first short report.pptx](https://reader035.vdocuments.site/reader035/viewer/2022062520/5695d3b81a28ab9b029eed8d/html5/thumbnails/7.jpg)
Cons and bottlenecks (Bottleneck):
The Milestone Picture:• The left gauge presented the outlet flow pressure, this is not
demanded!!• The outlet pressure must be equal to the liquefaction
conditions(P>80bar)• After a while from the beginning of the experiment this pressure is
applied to the first drum and that is the reason of compressor oil vomiting!
• What is the difference between CO2 cylinder and ours?

Extra Suggestion:
Starting to learn Aspen Hysys for modelling the system required.
