Analysis of the modified vacuum drying process in industrial heat exchanger

Modified vacuum drying process has become most prominent and cost effective technique to eliminate the redundant elements like moisture from the piping equipment in modern oil, natural gas, petro-chemical and fertilizer industries. Heat exchanger is one of them. It is essential to remove the moisture from the heat exchanger and other piping equipment to avoid the formation hydrates, corrosion etc. Presence of moisture inside of the pipes causes of hydrate formation and corrosion within the piping equipment. The research work provides the experimental data of modified vacuum drying process, which has been carried out on industrial heat exchanger. The estimated time for evacuation process is verified by experimental data received from Hydratight. Initially, major influencing factors that are associated with the piping equipment have been monitored using data logger. Controls of these factors are also important to accomplish the dryness measurement. Finally, phase wise moisture properties that change during the vacuum drying process based on field experiment and the effects of these factors also explained in this work.
