Economic modeling of carbon dioxide integrated pipeline network for enhanced oil recovery and geologic sequestration in the Texas Gulf Coast region

Naturally occurring CO2 is transported via pipelines to oil fields in West Texas to enhance production. A similar pipeline system is proposed for the Gulf Coast region of Texas. The CO2 would come from anthropogenic sources. Using GIS data, oil fields and CO2 sources are selected and a pipeline route is designed, taking into consideration rights of way and environmental sensitivities. We modified several pipeline cost models from the literature to capture recent construction cost escalations. Our resulting cost estimates agree with mid-to-high range cost quotes for pipelines reported to the Federal Energy Regulatory Commission by the companies.Bureau of Economic Geolog

Economic analysis of an integrated anthropogenic carbon dioxide network for capture and enhanced oil recovery along the Texas Gulf Coast

This paper explains the system economics of an example integrated network that uses anthropogenic CO2 from Texas Gulf Coast fossil power plants for enhanced oil recovery (EOR). These CO2 sources and sinks are connected via a pipeline network. A discounted cash flow model indicates that for all candidate oil fields that require less than an estimated $10/BBL in EOR capital expenditure, all three entities (CO2 capture, pipelines, and EOR operators) can have 20$55 per tonne of CO2 and $56 per barrel of oil. These results include no existing or future tax incentives, and there are some costs not yet included. However, a Monte Carlo analysis shows insight by indicating that the total system rate of return is most sensitive to oil production parameters. Oil price and estimated amount of recoverable oil are the most positively influential factors while the EOR capital cost is the most negatively sensitive factor. The capital costs of capture and CO2 price are less sensitive, both negatively affecting rate of return.Bureau of Economic Geolog

A Personalized Fractional Produce Maker For Superfluous Double Multipliers

In this RBMPPG (modified component product) generator is recommended; it removes the additional ECW and thus provides a single step for RBPP collection. Due to this high portability and no additional load, redundant binary (RB) can be used to create high performance servo. The traditional RB extension requires one line extension to the selected RB product (RBPP), because the error correction voice (ECW) is made up of both Radiated Radix-4 root recording (MBE) and RB code. This occurs during one additional RBPP component of the MBE expansion component.  Therefore, the planned RBMPPG produces fewer production products compared to the standard RB MBE multiplier. The results show that the proposed RBMPPG-based design significantly improves the space and power consumption or voice length of each parliamentary in this extension is approximately thirty-three; this reduction over previous NB servo leads to a slight increase in delay (approximately 6%). The power of the product delay can be reduced to ninety-five percent using the selected Serb rib compared to the existing RB servo

Mesoscale modeling of the martensitic transformations coupled with plasticity in engineering materials

The martensitic transformation (MT) that occurs in several engineering materials, such as steels, Zirconium (Zr) alloys and Titanium (Ti) alloys leads to some interesting material properties. In thisstudy, a physically based 3D elastoplastic phase-field model is developed to study the MT under various thermo-mechanical conditions in single crystals of steel and Zr-alloys. The input data for the model is acquired from different sources, such as CALPHAD, ab initio calculations and experimental measurements. The simulation results clearly show some of the typical characteristics of MT, such as: twinned microstructure formation, autocatalysis, Magee effect (variant selection mechanism under different stress-states), and transformation induced plasticity effect. The study of structure–property relations shows that the stress-states, strain rate as well as the temperature affect the mechanical behavior of steels, giving rise to different yield stresses and hardening behavior. The w phase formation in Zr and the coevolution of mechanical properties are also studied using this model

Microstructure and Mechanical Properties of Steel and Ni-Based Superalloy Joints for Rotors of High-Speed Electric Motors

High-speed electric motors, e.g., axially laminated anisotropic synchronous reluctance motors (ALA-SynRM), use a solid rotor manufactured by joining alternating layers of magnetic and non-magnetic metallic sheets. The strength of the dissimilar metallic joints is critical for the rotor's ability to withstand the operating conditions of the high-speed electrical machine. In this work, various dissimilar metallic joint configurations that can be used in high-speed ALA-SynRM rotors are studied by analyzing the shear strength, microstructure, hardness, and composition of the joints. Metallic joints of structural steels and Inconel (R) alloys fabricated by vacuum brazing and hot isostatic pressing (HIP) are studied. Finite element analysis (FEA) was performed to calculate the maximum shear stress of the joints that were subjected to various high speed operating conditions. The shear strength of the test specimens was measured and compared with FEA results. The microstructure and chemical composition of the joints were studied by using optical microscopy, scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) on SEM. The results show that the hot isostatic pressed S1100MC-IN718 joint achieved the highest ultimate shear strength (233.3 MPa) followed by vacuum brazed S355MC-IN600 joint (230.1 MPa) and HIP S355-IN718 (203.5 MPa), thereby showing that vacuum brazing and HIP can be viable manufacturing methods to fabricate a high-speed ALA-SynRM rotor

<i>In situ</i> observation of strain and phase transformation in plastically deformed 301 austenitic stainless steel

To inform the design of superior transformation-induced plasticity (TRIP) steels, it is important to understand what happens at the microstructural length scales. In this study, strain-induced martensitic transformation is studied by in situ digital image correlation (DIC) in a scanning electron microscope. Digital image correlation at submicron length scales enables mapping of transformation strains with high confidence. These are correlated with electron backscatter diffraction (EBSD) prior to and post deformation process to get a comprehensive understanding of the strain-induced transformation mechanism. The results are compared with mathematical models for enhanced prediction of strain-induced martensitic phase transformation
