What conditions must be met before purifying the gas flow? Answer: ① The minimum circulating volume of methanol in the system operates stably. ②The temperature of methanol entering the washing tower is around -35°C. ③The regeneration system is now working properly. ④The methanol-water separation system is now operating normally. ⑤Methanol spraying and nitrogen stripping have been in operation for over half an hour.
1 The minimum circulation rate of methanol in the system is maintained for stable operation. The methanol temperature in the two-stage scrubber tower is around -35°C. 3 The regeneration system is now normal. The 4 methanol/water separation system is operating normally. The 5 methanol spray and nitrogen stripping systems have been in operation for over half an hour.
①The minimum system methanol circulation rate remains stable during operation. ②The temperature of methanol entering the washing tower is around -35°C. ③The regeneration system is now working properly. ④The methanol/water separation system is operating normally. ⑤Methanol spraying and nitrogen stripping have been in operation for over half an hour.
