Analysis and Treatment of Large Differential Pressure at the Inlet of Expander and Large Temperature Difference at the Hot End of Dirty Nitrogen Channel of the the Main Heat Exchanger
In view of the anomaly that the main coolant level could not be maintained for normal production due to the increased differential pressure at the inlet of the expander and the large temperature difference at the hot end of the main heat exchanger dirty nitro-gen channel,the operating process of the molecular sieve purifier and the operating status of the booster cooler were judged,it was confirmed that the decline in adsorption perfor-mance of adsorbent of the purifier as well as leakage of the booster cooler were the main causes for the occurrence of the anomaly.The problem was effectively solved by temporary shutdown of the air separation to heat the air passages and strengthening the adsorption per-formance of the purifier adsorbent.
