![عکس صفحه اول مقاله: Estimation of maximum steam pressure by a mathematical linear technique Estimation of maximum steam pressure by a mathematical linear technique](/preview/png/1734472.png)
This paper presents a method for estimating the maximum pressure of steam which can be generated in recovering heat from individual processes, by partial linearization of the grand-composite curve. The technique is based on the pinch-analysis method by using a grand-composite curve (GCC), which can be approximated by using a mathematical function. The mathematical linear technique is composed of two steps:
• First step – Analyzing the possibility of additionally-available heat flow rate integration from different processes into one basic process
• Second step – Estimating the maximum possible steam-pressure to be generated.This linear technique was applied in an existing silver and oxide formalin process, resulting in generation of more steam with higher steam-pressure, thus producing an additional profit of 183900 EUR/a.
► The mathematical technique can determine the real mass flow rate for steam production.
► The mathematical technique can be easily and quickly selected for the best pressure steam generation.
► This method is applicable for new or retrofitted designs.
► With this method was modified the existing process.
