“…Yazarlar çalışmalarında, kondenstopların efektif çalışamaması sonucunda bazı endüstriyel tesislerde buharın %55'inin kaybedildiğini de gözlemlemişlerdir. Bir petrol rafinerisindeki buhar dağıtım hatlarının enerji verimliliğini inceleyen Singh ve arkadaşları [10] kazanda üretilen buharın %20 civarının kondestoplarda kaybedildiğini tespit etmişlerdir.…”

Steam traps are critical equipment for energy efficiency in various industrial facilities that use steam and steam lines intensively. Our study explains the types of steam traps, usage features, and issues in applications (such as montage, sizing, material compatibility, and working conditions) that lead to some common steam trap problems. The general causes of steam trap problems, methods of maintenance and fixing with where to pay attention are explained in detail. With the leakage measurements of steam lines of an industrial facility, the energy loss cost of steam traps and their fixing and maintenance costs are calculated, illustrating their economic importance. As a result of the analysis, one-year energy loss cost from the steam traps of the factory with 105 steam traps was determined to be 375,842 USD.

“…Most plants' managers are unaware that appropriate steam trap testing and maintenance may lower their fuel costs. According to the findings of the numerous programs used to analyze the operation of steam traps, the distribution network's steam traps cause around 20% of the steam exiting a boiler to be lost [6]. Vigorous steam traps would reduce steam losses considerably [7].…”

Steam, which is primarily employed as a heat transfer medium in process plants, is one of the most widely utilized energy carriers in the industrial sector. One of the factors that affects the cost of steam is how well the condensate collection, steam supply, and return systems of industrial steam systems perform. In a case study, the steam systems of a natural gas processing plant were simulated. The amount of demineralized water loss and, consequently, the identification of various solutions to improve the system were analyzed. The whole steam system was simulated using the MEASUR software platform (v 1.2), and by placing the operational information of the steam system, it was possible to create a baseline for the system, model saving solutions, and finally, provide a technical and economic evaluation of the solutions. Due to the high loss of steam condensate in the SRU steam system (more than 3000 kg per hour), solutions to improve the energy efficiency of the SRU steam system in the form of a maximum recovery of steam condensate (replacement of defective steam traps, redesign of the low-pressure condensate collection network, and high-pressure waste condensate collection) were evaluated with two price assumptions of current energy prices and real prices (the energy saving value of one cubic meter of natural gas is equal to 13 cents). The results show that, for current prices, the investment return period will be between 11.8 and 3.8 months. Moreover, in the main steam system of the refinery (unit 9200), there are three solutions: replacing and repairing defective steam traps, installing an expansion turbine instead of a steam pressure relief valve (PRV), and other solutions (including increasing boiler efficiency, automatic control of the boiler, and energy recovery boiler blowdown) under two price assumptions, the current and real prices of natural gas and demineralized water, were evaluated, and the modeling results show that the investment return period for each of the above solutions at the current prices is 10.2, 186, and 13.3, respectively. The investment return period is based on assuming real fuel and BFW prices are equal to 2.0, 37.6, and 1.7, respectively.
