“…In this study, the multiphase mixture model as a kind of Euler–Euler approaches was used. In line with previous simulations of complex geometries, such as SRU furnace 22 and finned channel heat exchangers, 23 in the present study the SST k- ω turbulence model was used as an efficient turbulent model. Following Zargoushi et al, 20 the dispersed and the continuous phases were considered by gas and liquid, respectively.…”

The cold box heat exchangers are used in petrochemical and gas refinery industries. Here, an industrial complex cold box equipped with a number of plate-fins is simulated by computational fluid dynamics. The model predicts the outlet vapor fraction, pressure drop, and outlet temperature with average absolute relative deviations of 0.17%, 3.3%, and 12.89% for all streams, respectively. The influence of obstruction in streams B and C on the computational fluid dynamics results are studied. When stream B or C is blocked, the remaining open streams experience an increase in pressure drop, temperature, and vapor fraction, which negatively affects the heat exchanger's performance over a long time. Finally, the computational fluid dynamics results of the cold box are compared with those of commercial software Aspen-EDR. Even though Aspen-EDR predicts an acceptable mean temperature and vapor fraction (phase change) along channels, it calculates pressure drop incorrectly. So, Aspen-EDR, computationally efficient software, can be used for modeling of mean temperature and phase change of flow in an industrial multi-stream cold box.

This work presents a comprehensive study of the combustion performance of an industrial furnace in an olefin plant using computational fluid dynamics (CFD) simulations. The focus was on analyzing the heat release pattern of bottom burners to optimize the furnace efficiency in steam-cracking processes. The study developed an accurate computational fluid dynamics (CFD) model for predicting combustion behavior in a cracking furnace. The computational model was validated by comparing the simulation results with industrial data and was used to investigate the impact of burner clogging and the importance of small holes in the body of burners in the furnace. The results also provided insights into the influence of excess air, temperature distribution, fluid behavior, composition of combustion products, and thermal efficiency of the furnace. The presented results contributed to a better understanding of parameters controlling combustion performance in steam-cracking furnaces.

“…These units play a crucial role in the overall operation of the refinery and facilitate the production of various valuable products. In the furnace chamber, almost one-third of hydrogen sulfide is burned by the process of oxidation, which results in the formation of sulfur dioxide and water [4]. Then, at temperatures above 1000 C, the residual portion of hydrogen sulfide interacts with sulfur dioxide to form sulfur and water in accordance with the overall equilibrium Claus reaction [4].…”

PT X is an Indonesian oil and gas processing industry. Recognizing the potential harm posed by gas emissions from oil and natural gas processing, PT X is actively working to control air pollution. One of their initiatives involves the construction of a Sulfur Recovery Unit (SRU) refinery to reduce sulfur gas emissions, particularly from H2S, by converting them into liquid sulfur products. The SRU refinery effectively processes approximately 73% of the H2S gas emitted during production. In January 2023, air quality measurements were conducted on stack 94-F-403 SRU, revealing the following results: the average concentration of SO2 emissions was 14.69 mg/m3, and the average concentration of NO2 emissions was 3.04 mg/m3. These measurements indicate that both parameters fall below the quality standards set by the Indonesian Minister of Environment Regulation No. 13 of 2009, which defines acceptable emission limits for the oil and gas industry. Based on these findings, it can be concluded that the emissions from stack 94-F-403 SRU are classified as non-polluting, adhering to the Indonesian government's quality standards. PT X's commitment to environmental responsibility is evident through their implementation of the SRU refinery, which significantly reduces gas emissions and ensures compliance with regulatory requirements.
