Optimal slot dimension for skirt support structure of coke drums

Edward WANG, Zihui XIA

Frontiers of Mechanical Engineering 2018, Volume 13, Issue 4,   Pages 554-562 doi: 10.1007/s11465-018-0513-y

Abstract:

The skirt-to-shell junction weld on coke drums is susceptible to fatigue failure due to severe thermal cyclic stresses. One method to decrease junction stress is to add slots near the top of the skirt, thereby reducing the local stiffness close to the weld. The most common skirt slot design is thin relative to its circumferential spacing. A new slot design, which is significantly wider, is proposed. In this study, thermal-mechanical elastoplastic 3-D finite element models of coke drums are created to analyze the effect of different skirt designs on the stress/strain field near the shell-to-skirt junction weld, as well as any other critical stress locations in the overall skirt design. The results confirm that the inclusion of the conventional slot design effectively reduces stress in the junction weld. However, it has also been found that the critical stress location migrates from the shell-to-skirt junction weld to the slot ends. A method is used to estimate the fatigue life near the critical areas of each skirt slot design. It is found that wider skirt slots provide a significant improvement on fatigue life in the weld and slot area.

Abstract:

In order to gain a deeper understanding of the significance of the Chinese Academy of Engineering's "China Intelligent Manufacturing Development Strategy Research Report Based on the New Generation of Artificial Intelligence", the author adopts the method of deconstruction and reconstruction, to analyze the Reference Architecture Model of Industrial 4.0 (RAMI 4.0) of Germany, and compared with the general architecture of intelligent manufacturing proposed in the report of the Chinese Academy of Engineering, and similarities and differences of each other are found. It is believed that the general architecture of the intelligent manufacturing in China is superior in intelligence. This is the Chinese contribution to the development of intelligent manufacturing. At the same time, the analysis deepens the understanding of the both architectures.

Frontiers of Chemical Science and Engineering 2013, Volume 7, Issue 1,   Pages 110-115 doi: 10.1007/s11705-013-1316-7

Abstract: In this work, the enthalpy of fusion and melting points of 2-( -butyl)-5-methylphenol (2B5MP) and 2-( -butyl)-4-methylphenol (2B4MP) were measured by differential scanning calorimetry (DSC). The binary solid-liquid equilibrium (SLE) of both compounds were predicted by integrated computer aided system (ICAS) and measured by DSC. The corresponding eutectic molar composition is 0.6998 and the eutectic temperature is 281.96 K. The quasi-static heat capacities of 2B5MP and 2B4MP were evaluated by stochastic temperature modulation DSC technique (TOPEM). The SLE experimental data were correlated using the Margules, Wilson, and non-random two liquid (NRTL) equations and a good agreement between measurement and calculation could be obtained.

Free radical scavenging window of infertile patients with polycystic ovary syndrome: correlation with

Bo Huang, Zhou Li, Xinling Ren, Jihui Ai, Lixia Zhu, Lei Jin

Frontiers of Medicine 2017, Volume 11, Issue 2,   Pages 247-252 doi: 10.1007/s11684-017-0519-6

Abstract:

The activity of free radicals in follicular fluid was related to ovarian responsiveness, in vitro fertilization (IVF), and embryo transfer success rate. However, studies analyzing the relationship between the free radical scavenging capacity and embryo quality of infertile women with polycystic ovarian syndrome (PCOS) were lacking. The aim of this study was to evaluate the relationship between the free radical scavenging window of women with PCOS and their embryo quality. The free radical scavenging capacity of follicular fluid from women with PCOS was determined by a,a-diphenyl-b-picrylhydrazyl (DPPH), 2,2-azinobis (3-ethylbenzthiazoline-6-sulphonic acid) assay, superoxide radical, and reactive oxygen species (ROS) assay. In the DPPH and ROS assays, the follicular fluid from grades I and II embryos was significantly higher than the follicular fluid from grades III and IV embryos. The lower control limit of DPPH radical scavenging capacity and upper control limit of ROS level were 13.2% and 109.0 cps, respectively. The calculated lower control limit and upper control limit were further confirmed in the follicular fluid of embryos of all grades. These cut-off values of free radical scavenging activity of follicular fluid could assist embryologists in choosing the development of embryos in PCOS patients undergoing IVF.
