Acknowledgment

The authors would like to thank the board of directors of Sazeh Engineering Consultants Co. for its support.

Notes

1Note 1: Maximum gas velocity in each bottle is 1 m/s. During normal operation, each bottle receives more than 20% ofthe distribution rate.

2Note 2: Maximum gas velocity in each splitter is 2 m/s.
