Abstract

The task of pressure reducing stations is to regulate the gas pressure in the standard range for different uses. The indirect water bath heater is used as part of the gas pressure transfer station to heat the gas before the pressure drops so that the condensate temperature in the gas does not reach the point of hydration formation during breaking and reducing the gas pressure. In this study, according to the characteristics of natural gas and heat transfer relations and mass survival and energy equations, an acceptable analysis of the thermal behavior of heaters has been done and the heater is modeled with appropriate accuracy and the effect of geometric parameters on the heat performance of the heater is investigated. By changing the heater geometry from cylindrical to cubic geometry, acceptable results were obtained by increasing efficiency and reducing fuel consumption.
