Abstract Natural gas production occurs in specific regions of the US, after which it is processed and transported via an interconnected network high-pressure interstate pipelines. While presence hazardous air pollutants (HAPs) unprocessed, upstream natural has been documented, little published on their midstream supply. We systematically evaluated publicly available, industry-disclosed HAP comp...

Aqila Wash Station is a micro business that washes motorcycles, mats and carpet in Deli Tua, sub-district North Sumatra province. Washing motorcycle may consume large amount of time this decreases customers’ satisfaction. The whole process performed manually using very simple tools tires the workers quickly, which results decrease their work quality. most common problem face soap depletion. nex...

Interest in compressed air energy storage (CAES) technology has been renewed driven by the need to manage variability form rapidly growing wind and solar capacity. Distributed CAES (D-CAES) design aims to improve the efficiency of conventional CAES through locating the compressor near concentrated heating loads so capturing additional revenue through sales of compression waste heat. A pipeline ...

Generation of coherent short-wavelength radiation across a plasma column is dramatically improved under traveling-wave excitation (TWE). The latter is optimized when its propagation is close to the speed of light, which implies small-angle target-irradiation. Yet, short-wavelength lasing needs large irradiation angles in order to increase the optical penetration of the pump into the plasma core...

A better understanding of turbulent unsteady flows is a necessary step towards a breakthrough in the design of modern compressors. Owing to high Reynolds numbers and very complex geometry, the flow that develops in such industrial machines is extremely hard to predict. At this time, the most popular method to simulate these flows is still based on a Reynolds-averaged Navier-Stokes approach. How...

In a hydrogen station that operates with direct fueling through the use of 700 bar boost compressor, outlet temperature can significantly increase, stressing chiller system. This paper evaluates improvements be made to auxiliary cooling system integrated compressor. Both theoretical modeling and experiments were performed at Cal State LA Hydrogen Research Fueling Facility. The findings suggest ...

Design models of multi- stage, axial flow compressor are developed for gas turbine engines. Axial flow compressor is one of the most important parts of gas turbine units. Therefore, its design and performance prediction are very important. One-dimensional modeling is a simple, fast and accurate method for performance prediction of any type of compressors with different geometries. In this appro...

Pipe line inspection is an important task where robotics could be applied extensively. Robotic pipeline inspection devices reported in literature are primarily of internal type, requiring special preparation of pipelines for their deployment and retrieval. In this context, robotic systems which can traverse along the external surface of the pipeline structure have the advantage of being able to...

Pipeline networks are the safest transportation of oil and gas-related products that may be susceptible to failures. These kinds failures due reason manufacturing defects, degradation material, environmental interference third party. issues addressed through Internet Things (IoT) based solutions give promising outcomes in predicting monitoring. The IoT can combine sensor technologies monitor ga...
