The more developing technology enhances the need for energy; this requires the maximization of the performance of power plant components and energy. Refinery Unit (RU) is currently one of the real applications. Reliable equipment is required in running a massive industry. In running the oil production process at Refinery Unit (RU), the thing that needs to be put into consideration is pumps. A pump is a device for distributing fluids from one place to another. In Refinery Unit (RU), the pump is not only for oil but also for other fluids. In this research at Refinery Unit, the pump that is to be discussed is a centrifugal pump 211-P-25A. The objective of this research is to analyze the damage of pump 211-P-25A, which indicated high vibration. This causes the pump not to work optimally, so it requires the right maintenance. The research is done by using an analytical method, visual observation towards impeller and shaft, and comparing the results in accordance to API 610. Afterwards, the right maintenance will be known for centrifugal pump 211-P-25A to reduce the high vibration that occurred in the pump. High vibration may be caused by cavitation and internal recirculation. The damage in pump 211-P-25A is caused by repeated internal circulation, which causes damage to the impeller and high-speed shaft. Pump 211-P- 25A experiences high vibration due to low flow. The flow produced is 2.67 m³/h, with a pump design minimum flow of 8.6 m³/h. This causes damage to pump components.

Due to this damage, the performance of the pump will not be optimal, and its efficiency will be reduced.

High Vibration; Internal Recirculation;

Cavitation; Centrifugal Pump

Smoke inhalation is a major cause of death in fire accident. Three quarters of building fire casualties were the result of excessive smoke inhalation, even with the presence of a control system. One of the main reasons to a high percentage of fatality is poor circulation and exhaustion of smoke. A proposed system, including an integrated ACMV exhaust with additional louver, will be simulated and compared with the current conventional approach, the fixed pressurization system. The purpose of this study is to determine the effectiveness of the newly proposed approach to smoke exhaustion.

Results showed that the path of obscuration for the conventional system in the room displayed a lowered value of 8.77 %, as compared to 9.71% for the integrated ACMV system, due to the greater propagation of smoke out of the room. The results are in agreement as there is a noticeably faster subsiding of hot air temperature at the corridor for the integrated ACMV system than that of the conventional system, after the peak temperature spread of 115 seconds. The current study concluded that the proposed integrated ACMV system with additional louver is more effective for smoke control than the conventional design.

1. Introduction

The United States Fire Administration estimated in 2016 that there were 364,300 residential building fire cases, causing 2,775 deaths, 11,025 injuries, and a total loss of $US5,726,300,000 in the United States. Out of the aforementioned cases, 375 deaths were due to smoke inhalation [1]. While advance research in the green building is paramount [2-5]; the safely egress for occupants during fire event is equally important. The purpose of a smoke control system is to trigger an emergency whereby toxic smoke or fire occurs inside an enclosed room; such a system reduces the chances of

The aim of this work is to investigate the forced convective heat transfer phenomena and fluid flows of water-based Al2O3 nanofluids in the baffled shell and tubes heat exchanger (STHE). Water as a hot fluid flows in the side of the tubes, and Al2O3

nanofluids as cooling fluid flow in the shell side. Numerical investigations have been carried out based on the continuity, momentum, and energy equations which are solved by using the finite element method with the help of the COMSOL 5.4 CFD software. The obtained results were presented by average Nusselt number, streamlines, isotherms, and various physical parameters which are a volumetric fraction of nanoparticles (1%≤ Cv ≤3%). The obtained results reveal an increase in the heat transfer with the rise of inlet velocity and volume fraction, where the Nusselt numbers are augmented by 0.1 %, 3.96 % and 7.62 % for Cv = 1%, 2% and 3%, and the friction factor are increased by 22.41 %, 24.14 % and 26.72 % for Cv = 1%, 2% and 3%

compared with base fluid respectively. In addition, the presence of baffles inside tubular heat exchangers can create a better mixture of fluids which is augmenting heat transfer execution. The choice of these parameters is important to get the maximum improvement of heat transfer with minimum entropy consumption.

1. Introduction

The shell-and-tube Heat exchangers (STHEs) are important equipment that are mostly used in many engineering processes such as electric power generation, air-conditioning, petroleum refineries, natural gas processing, refrigeration, and nuclear power systems [1-4]. The multi-function services and application options provided by the STHEs make this device an important element that plays an essential role in these industrial processes. In this field, the looking for their processes of
