Exhaust Gas Cleaning System
| Item | ContiOcean Product | Other Product | |
|---|---|---|---|
| 1 | Material of Scrubber tower | Alloy 31 is chosen as the main material due to the excellent heat resistance and corrosion resistance. | SMO 254, the main material may lead to the corrosion of the scrubber tower after a long period of use. |
| 2 | Scrubber tower structure and installation | Scrubber tower chooses welded or bolted connection instead of flange to avoid leakage. | Scrubber tower uses flange connection which may cause water leakage. Scrubber tower higher than 10m is supported by 4 I-beams. |
| 3 | Scrubber tower connection and interface | Scrubber tower will be customized designed during engineering design process to achieve the best effect of . Allinlets are designed with 10-degree angle of inclination to avoid accumulated water. | Scrubber tower design is fixed and engineering design company can only conduct retrofitting according to designed pipeline. In this case, best retrofitting design can not be guaranteed. |
| 4 | Water draining | Drain water outlet diameter is 1.5 times bigger than inlet and cone angle for draining at the bottom is 65°, which can avoid accumulated water. | Drain water outlet diameter is 1.3 times bigger than inlet and cone angle for draining at the bottom is 70-75°, which may cause accumulated water. |
| 5 | Packing | Packing has random inclined structure with 20%back pressure. |
|
| 6 | Spray nozzle | No movable parts. | In some designs, there're rotating blades installed inside spraynozzle. |
| 7 | Hardware-in-the-loop test (HIL test) | ContiOcean cooperates with DNV-GL to conduct HILtest. HIL test can simulate working conditions of the workshop before installation and ensure the reliability of electrical control system, which can greatly save the commissioning time. |
