| Abstract: |
| The ethylene glycol injection inhibitors and outside refrigeration technology have been used in dehydration and dehydrocarbon device of Moshen No.1 Well with the capacity of 500×103 m3/d. Owing to the lack of experience in the dosage of glycol, the scraper film evaporator used in alcohol recovery process is one of the difficulties in trial run. Based on the theoretical calculation through analyzing the character of the alcohol recovery processes and calculating the theoretical addition amount of ethylene glycol inhibitors, the optimal operating parameters were explored in the actual operation, which would provide technical support for successful production. |
