Performance assessment of a power-to-gas process based on reversible solid oxide cell

Hanaâ Er-rbib, Nouaamane Kezibri, Chakib Bouallou

Frontiers of Chemical Science and Engineering 2018, Volume 12, Issue 4,   Pages 697-707 doi: 10.1007/s11705-018-1774-z

Abstract:

Due to the foreseen growth of sustainable energy utilization in the upcoming years, storage of the excess production is becoming a rather serious matter. In this work, a promising solution to this issue is investigated using one of the most emerging technologies of electricity conversion: reversible solid oxide cells (RSOC). A detailed model was created so as to study the RSOC performance before implementing it in the global co-electrolysis Aspen PlusTM model. The model was compared to experimental results and showed good agreement with the available data under steady state conditions. The system was then scaled up to a 10 MW co-electrolysis unit operating at 1073 K and 3 bar. The produced syngas is subsequently directed to a methanation unit to produce a synthetic natural gas (SNG) with an equivalent chemical power of 8.3 MWth. Additionally, as a result of a heat integration analysis, the methanation process provides steam and electricity to operate the rest of the units in the process. A final CO2 capture step is added to ensure the required specifications of the produced SNG for gas network injection. Lastly, the overall performance of the power-to-gas process was evaluated taking into account the energy consumption of each unit.

Status and Prospect of Remanufacturing Technology for Tubing and Sucker Rods

He Liu,Tao Li,Wei-ye Han,Qiang Chen,Shou-zhi Huang,Er-yang Ming,Qiang Sun

Frontiers of Engineering Management 2016, Volume 3, Issue 3,   Pages 258-263 doi: 10.15302/J-FEM-2016031

Abstract: As the main consumables, huge amount of tubing and sucker rods are abandoned annually. The current remediation technology could only enable part of abandoned tubing and sucker rod to be reused in a degraded way, leading to a big resource waste. The production, use and remediation methods of tubing and sucker rod are analyzed here. Remanufacturing technology of abandoned tubing based on self-propagating high temperature synthesis (SHS) is proposed. Economic, environmental and social benefits of large scale application of this technology are evaluated. And then various factors that restrict the popularization of remanufacturing technology in the petroleum industry are studied and suggestions are given in the end. The results indicate that unlike conventional remediation methods, remanufacturing technology can extend the service life of abandoned tubing to reach or even exceed that of a new one. Meanwhile it can also reduce the cost effectively, and achieve significant economic and social benefits. We should expand remanufacturing technology areas in the petroleum industry and achieve stable, healthy development in the low oil price situation. The scientific standards for remanufactured products should be enacted, and new management mode of the remanufactured products should be developed.

Type 2 diabetic patients with non-alcoholic fatty liver disease exhibit significant haemorheological abnormalities

Hui Dong, Fu’er Lu, Nan Wang, Xin Zou, Jingjing Rao

Frontiers of Medicine 2011, Volume 5, Issue 3,   Pages 288-293 doi: 10.1007/s11684-011-0127-9

Abstract: Haemorheological abnormalities have been described in diabetes mellitus, as well as in non-alcoholic fatty liver disease (NAFLD). However, the relationship between the changes in liver fat content and haemorheology is unknown. The current study aims to show the correlation between haemorheological parameters and intrahepatic lipid content (IHLC) in patients with type 2 diabetes. The serum biochemical markers, such as fasting plasma glucose (FPG), haemoglobin A1c (HbA1c), liver enzymes, lipid profiles, and haemorheological properties, were examined. IHLC was quantified using proton magnetic resonance spectroscopy ( H-MRS) scanning of the liver. A significant correlation was observed between IHLC and whole blood viscosity at high, middle, and low shear rates. IHLC also positively correlated with haematocrit, the reduced whole blood viscosity at low and middle shear rates, and the erythrocyte aggregation index. Diabetic patients with NAFLD exhibited significant haemorheological abnormalities compared with patients without NAFLD. In summary, haemorheological disorders are linked to non-alcoholic fatty liver in type 2 diabetes.

Anefficient data layout scheme for better I/O balancing inRAID-6 storage systems

Ping XIE,Jian-zhong HUANG,Er-wei DAI,Qiang CAO,Chang-sheng XIE

Frontiers of Information Technology & Electronic Engineering 2015, Volume 16, Issue 5,   Pages 335-345 doi: 10.1631/FITEE.1400362

Abstract: Among redundant arrays of independent disks (RAID)-6 codes, maximum distance separable (MDS) based RAID-6 codes are popular because they have the optimal storage efficiency. Although vertical MDS codes exhibit better load balancing compared to horizontal MDS codes in partial stripes, an I/O unbalancing problem still exists in some vertical codes. To address this issue, we propose a novel efficient data layout, uniform P-code (UPC), to support highly balanced I/Os among P-coded disk arrays (i.e., PC). In UPC, the nonuniformly distributed information symbols in each parity chain of P-code are moved along their columns to other rows, thus enabling the parity chain to keep original parity relationships and tolerate double disk failures. The UPC scheme not only achieves optimal storage efficiency, computational complexity, and update complexity, but also supports better I/O balancing in the context of large-scale storage systems. We also conduct a performance study on reconstruction algorithms using an analytical model. Besides extensive theoretical analysis, comparative performance experiments are conducted by replaying real-world workloads under various configurations. Experimental results illustrate that our UPC scheme significantly outperforms the PC scheme in terms of average user response time. In particular, in the case of a 12-disk array, the UPC scheme can improve the access performance of the RAID-6 storage system by 29.9% compared to the PC scheme.

A comprehensive study of hydrogen production from ammonia borane via PdCoAg/AC nanoparticles and anodic current in alkaline medium: experimental design with response surface methodology

Hilal ÇELİK KAZICI, Şakir YILMAZ, Tekin ŞAHAN, Fikret YILDIZ, Ömer Faruk ER, Hilal

Frontiers in Energy 2020, Volume 14, Issue 3,   Pages 578-589 doi: 10.1007/s11708-020-0808-7

Abstract: In this paper, the optimization of hydrogen (H ) production by ammonia borane (NH BH ) over PdCoAg/AC was investigated using the response surface methodology. Besides, the electro-oxidation of NH BH was determined and optimized using the same method to measure its potential use in the direct ammonium boran fuel cells. Moreover, the ternary alloyed catalyst was synthesized using the chemical reduction method. The synergistic effect between Pd, Co and Ag plays an important role in enhancement of NH BH hydrolysis. In addition, the support effect could also efficiently improve the catalytic performance. Furthermore, the effects of NH BH concentration (0.1–50 mmol/5 mL), catalyst amount (1–30 mg) and temperature (20°C–50°C) on the rate of H production and the effects of temperature (20°C–50°C), NH BH concentration (0.05–1 mol/L) and catalyst amount (0.5–5 µL) on the electro-oxidation reaction of NH BH were investigated using the central composite design experimental design. The implementation of the response surface methodology resulted in the formulation of four models out of which the quadratic model was adjudged to efficiently appropriate the experimental data. A further statistical analysis of the quadratic model demonstrated the significance of the model with a p-value far less than 0.05 for each model and coefficient of determination ( ) of 0.85 and 0.95 for H production rate and NH BH electrroxidation peak current, respectively.
