abstract
during natural gas processing, water in natural gas may cause to hydrates formation in pipelines which may lead to serious damages to process equipments. given the problems raised by present of water in natural gas, glycol solvent uses to remove water.in contact of glycol with gas always an amount of btex and voc absorb along with water, which on glycol recovery process, these substances separate and release in the atmosphere. btex and voc compounds cause many hazard for human and environment. in addition, these substances have diverted effect on glycol processing function and decrease the absorbance rate. therefore we studied methods for removing btex and voc and preventing of their release on atmosphere and also methods for increasing glycol purification and finally increase hydration overall efficiency. after assessment of technical, economical and environmental perspectives, among all available methods and processes one efficient process for hydration of natural gas has been proposed which was free from mentioned problems.

Safety assessment of glycol recovery unit in a gas refinery by failure mode and effects analysis technique
Background: The reliability and safety of gas refineries are strongly associated with the reliability of other parts of the system. Defect and failure in one part of a system can cause total system breakdown or accident. The failure and damage in these equipment such as transformers and boilers results in not only the equipment damage and human injuries but also productivity reduction. The purp...
