Abstract:
While dismantling nuclear power plants, the reactor vessel internal is cut underwater using mechanical and thermal cutting. In laser thermal cutting, assist gas must be used to remove melted metal; consequently, a large number of radioactive aerosols can be generated. To reduce the generation of aerosols, the assist gas pressure should be lowered. However, below the pressure limit, the molten metal is not well-removed from the cut surface and fails to cut. In this study, an assist gas visualization experiment was performed to find a condition for the gas to flow well inside the cut surface, ev

It is this undesirability of Oil/Gas facilities to generate smoky flares that has endeared them to providing the most available flare assist systems in their facility. A gas processing fa

The present study is carried out to investigate the effect of the assist gas jet on the thermal integration due to repetitive pulsed laser heating.

A numerical scheme using the control volume approach is employed to solve the two-dimensional axisymmetric governing equations of flow and heat conduction.

Abstract For many laser machining applications, an assist gas is required. However, for applications with high pressure or temperature gradients, the density of the assist gas is not homogeneous.

This paper investigates the effects of using nitrogen gas on Mist cutting. In this study we tried to improve the cooling effect of mist on cutting by using N2 gas to assist cooling. As a result, tool breakage was prevented when using carbide tools and a large reduction in tool wear was confirmed when using cermet tools. Our conclusion is that N2 gas assisted mist cutting reduces oxidation wear, which means that the cutting characteristics are better than in conventional mist cutting.

A novel cooling mechanism based on evaporation of thin liquid films is presented for thermal management of confined heat sources, such as microprocessor hotspots.

The vapor generated by evaporation is continuously removed by using a dry sweeping gas keeping the membrane outlet dry. This thesis presents a detailed theoretical, computational and experimental

A new process of combining gas injection with compression moulding was developed and studied in this research work. The process is called Gas Assisted Compression Moulding (or GasComp). The principle is based on the injection of nitrogen gas during a conventional compression moulding cycle.

The gas assists in the flow by coring out the material, reducing the weight by up to 45 percent and increasing the dimensional stability of the component. Novel glas

Polymerised hexafluoropropene displayed increased fluorine contents at high powers; this is at odds with perfluorohexane which demonstrated lower fluorine contents. Differing reaction mechanisms between saturated and unsaturated perfluorocarbons were proposed to explain this. Both perfluorocarbons were found to give increa

Full text
Abstract:
The use of PEMS to meet monitoring requirements offers the potential for significant cost savings and reduced manpower needs for operation and maintenance over the use of traditional continuous emission monitoring systems (CEMS). However, a single source of pertinent information on available systems does not exist. The two main objectives for this study were to: evaluate and document the gas transmission industry's experience with PEMS for gas turbines, and provide a comprehensive information base to assist future industry user's decision-making regarding PEMS use.

Abstract:
This Final Report summarizes the results of a project to develop a preliminary screening process to assist reservoir engineers in evaluating various gas reservoir prospects. A gas reservoir screening program was developed during the project. Designed for use with desktop PCs, GMOD is an analytical gas well production model based on published theoretical reservoir models and is capable of generating well production data quickly and efficiently for horizontal, vertical, slant, and hydraulically-fractured vertical gas wells. A parametric study was performed to investigate the effects of numerous

Full text
Abstract:
To ensure proper operation and accuracy of Natural Gas meters, it is important that the meters and associated piping be maintained in a clean condition consistent with both manufacturer production and AGA report provisions. This can best be assured through a comprehensive diagnostic and in section program complete with efficient internal cleaning as required. The objective of this project was to provide a comparison between continuous chemical injection cleaning with the system remaining online and conventional manual disassembly and cleaning techniques with the system offline.

Gartland. L52079 Internal Corrosion in Dry Gas Pipelines During Upsets. Pipeline Research Council International, Inc. (PRCI), 2003. http://dx.doi.org/10.55274/r0011313.

Full text
Abstract:
The main objective of the present project has been to develop a computer program, named GasCor, that can be used to estimate the corrosion related risk of operating dry gas pipelines under conditions where upsets may occur. An upset is here considered as an event that may cause corrosive liquid water to be present in some part of the pipeline within a certain time period. The computer program is meant to be a screening tool that can assist in the evaluation of the severity of the corrosion rate as well as in the location of the positions where the most significant corrosion is to be expected.

Full text
Abstract:
This report addresses the need for reliable, validated models to assist gas companies in determining the minimum spacing between adjacent pipelines to help ensure safe and reliable operation in the event of a rupture. The objective is to evaluate the exposure of a pipeline due to the rupture and ignition of the escaping gas of an adjacent pipeline.

Full text
Abstract:
To maintain the integrity and reliability of natural gas transportation systems, system operators ensure that products in transit remain in the gas phase under foreseeable operating conditions. Compliance with pipeline hydrocarbon dew point (HCDP) specifications are demonstrated though in-situ testing or predictive models based on Equations of State (EOS) calculations. Numerical prediction of HCDP is a product of contributing elements, including gas chromatography, calibration gas quality, thermophysical science and the experimental data that underpins equations of state.

Abstract:
This report documents the development of a set of Guidelines for the use of subsurface safety valves in gas storage wells. The final version of the Guidelines is included in Appendix A at the end of the report. The Guidelines were formulated based on input from gas storage well operators and subsurface safety valve manufacturers. The Guidelines are a single source of information designed to assist the storage well operator in selecting, installing, operating, and maintaining subsurface safety valves in his wells. The information contained in the Guidelines should benefit both the first time us

Abstract:
This program developed a stress-corrosion cracking (SCC) protocol for use in assessing the likelihood of the conditions necessary for high pH SCC on individual pipeline segments and an SCC integrity management plan to assist operators in selecting appropriate remedial actions depending on whether SCC is located and the potential consequences. This protocol was developed as a conservative guideline based on existing knowledge at the time of development. This high pH SCC protocol was validated using data from 15 SCC service incidents collected during the conduct of this program and three test ca

Abstract:
This document presents a concept paper, intended to assist the Andean/Amazon Basin countries to develop proposals, in consultation with indigenous organizations, for 1) the financing of consultations with indigenous peoples and 2) the undertaking of a series of environmental, and socio-cultural activities prior to the governments' calls for bids on oil and gas exploration/development blocks. Although the Initiative is restricted to the hydrocarbon sector, it can be applied more broadly to bids on other similar activities such as mining and forestry resource concessions. Accordingly, it can be
