Pressure vessel towers used in the petrochemical and chemical industry are designed to accommodate numbers of internals including trays and beds resulting in tall vertical structures. Transportation of tall towers from the fabrication shop to the construction site presents challenges that can result in high transportation costs or a logistically impossible task of moving the vessel. One of the solutions to this problem is to shorten the tower for transport by cutting part of the tower skirt and welding it in the field. Depending on the location, welding on site can be expensive, labour intensive and may cause problems in the quality of the weld and the tower being out of level. Using a flanged skirt connection will reduce the field labour spent on connecting the bottom part of the skirt to the rest of the vessel. The challenge that lies in front of designers is that the current codes and available literature do not give a specific design and calculation guidance for implementing such a solution. This paper looks at different analytical methods to be used for the design of a skirt splice. Methods provided by Jawad and Farr, the Canadian Institute of Steel Construction, the American Institute of Steel Construction, and the Peterson Method from the European Commission's High-Strength Tower in Steel for Wind Turbines (HISTWIN) are analyzed. Based on this analysis, the most optimal and safe design and fabrication methodology for implementing a Flanged Skirt Connection is proposed. Copyright © 2014 by ASME.

A laser-stripe system for the automation of welding processes in heavy industries is presented. Conventional methods use human intervention. A new solution using only common usage computer components has been developed, offering at least the same quality of performance at a low price, making laser systems without human intervention attractive for cost sensitive applications in heavy industries. A new system that guarantees satisfactory tracking results even when the welding gap geometry varies strongly or is distorted by noise has been developed. © 2011 IEEE.

This paper describes the changes made to existing version of the Structural Design Criteria for In-vessel Components (SDC-IC) within the ITER project, as a result of the revision and update process carried out recently. Several ITER components, referred to as In-vessel Components, are located inside the ITER Vacuum Vessel. © 2011 by ASME.

The components located inside the ITER vacuum chamber (in-vessel components - IC), due to their specific nature and the environments they are exposed to (neutron radiation, high heat fluxes, electromagnetic forces, etc.), have specific design criteria which are, in this paper, referred as Structural Design Criteria for In-vessel Components (SDC-IC). The development of these criteria started in the very early phase of the ITER design and followed closely the criteria of the RCC-MR code. Specific rules to include the effect of neutron irradiation were implemented. In 2008 the need of an update of the SDC-IC was identified to add missing specifications, to implement improvements, to modernise rules including recent evolutions in international codes and regulations (i.e. PED). Collaboration was set up between ITER Organization (IO), European (EUDA) and Russian Federation (RFDA) Domestic Agencies to generate a new version of SDC-IC. A Peer Review Group (PRG) composed by members of the ITER Organization and all ITER Domestic Agencies and code experts was set-up to review the proposed modifications, to provide comments, contributions and recommendations. © 2013 Elsevier B.V.

ESSEN, 23-Feb-2017 — /EuropaWire/ — The new CyPlus Idesa sodium cyanide production plant was officially opened with an inauguration ceremony in Coatzacoalcos (Veracruz, Mexico) in the presence of Dr. Klaus Engel, Chairman of the Excecutive Board of Evonik Industries and Patricio Gutiérrez Fernandez, Chairman of CyPlus Idesa. CyPlus Idesa is a joint venture between German Evonik and Mexican Grupo IDESA. The new sodium cyanide plant has a capacity of 40,000 metric tons and uses state-of-the-art hydrocyanic acid and cyanide technologies. Special attention was dedicated to the compliance of all environmental and safety regulations ensuring that production of sodium cyanide complies with the provisions of the “International Cyanide Management Code” (ICMC). Mining operations in the gold and silver mining industry use sodium cyanide to extract precious metals from the mineral. Mexico is the number one producer of silver in the world and ranks among the top 15 producers of gold worldwide. “The new local production facility will make us an even better and more flexible supplier for our customers in the region. The facility represents another important step in the growth strategy of Evonik,” said Klaus Engel. In addition to representatives of both companies’ top management, the inauguration ceremony was attended by high-ranking representatives of the Federal government, the state of Veracruz and the city of Coatzacoalcos. Further invitees included customers and suppliers. CyPlus Idesa started up production in close and trustful collaboration with the joint venture partner, who already operates chemical plants in Coatzacoalcos. Evonik has brought production technology and process know how to the joint project, while Grupo IDESA made key contributions based on its more than sixty years of experience in the Mexican chemical sector. CyPlus Idesa S.A.P.I de C.V., Mexico, is a 50:50 joint venture of Grupo Idesa, Mexico and Evonik, Germany, duly incorporated in June 2013. Evonik, the creative industrial group from Germany, is one of the world leaders in specialty chemicals. Profitable growth and a sustained increase in the value of the company form the heart of Evonik’s corporate strategy. Its activities focus on the key megatrends health, nutrition, resource efficiency and globalization. Evonik benefits specifically from its innovative prowess and integrated technology platforms. Evonik is active in over 100 countries around the world. In fiscal 2015 more than 33,500 employees generated sales of around €13.5 billion and an operating profit (adjusted EBITDA) of about €2.47 billion. CyPlus is a globally established company in cyanides. The Evonik subsidiary provides innovative products, technologies and services to customers in the mining, chemical, pharmaceutical, and surface treatment industries. The company meets the extensive and strict requirements of the international mining industry as a supplier of cyanides in accordance with the provisions of the “International Cyanide Management Code” (ICMC). Production sites in Europe as well as sales and distribution offices on all continents provide customers swift and reliable service. CyPlus regards itself as a pacesetter of progress and sustainability.

CALGARY, ALBERTA--(Marketwired - Nov. 21, 2016) - International Frontier Resources Corporation ("IFR" or the "Company") (TSX VENTURE:IFR)(OTCQB:IFRTF) is pleased to announce that its jointly owned Mexican company Tonalli Energia ("Tonalli") has identified high interest development targets at its onshore oil and gas development block, Tecolutla. Upon signing the License Contract on August 25th, 2016, Tonalli acquired additional 3-D seismic covering an extended area including and offsetting the Tecolutla block. We have subsequently reprocessed this high quality data and continue to analyze results. Tecolutla was originally drilled without the benefit of modern seismic. After review of the reprocessed 3D seismic, we have identified areas of the reservoir which we believe, are significantly higher and thicker than previously reported and which have not been penetrated by existing wells. Tonalli will formally assume operatorship of the Tecolutla Block from PEMEX on November 23rd, 2016. Regulatory processes are underway and we expect to initiate our operations program in the first half of next year. We are pleased by our progress in the Mexican government's regulatory processes. Tonalli has already initiated oil field services contracting and we have found service providers to be readily available and competitive in their pricing. Existing drill sites and extensions of existing drill sites will be utilized to execute our operations program. Tonalli plans to drill its first well in H1 2017. We intend to engage our partner, Grupo IDESA, to truck production to under-utilized PEMEX midstream facilities in the region, taking advantage of 12-month surface access at Tecolutla using existing roads, which require only minimal upgrades. The Tecolutla Block was awarded to Tonalli as part of the first round and third call of Mexico's oil and natural gas "mature fields" bid round ("Round 1.3"), the first in almost 80 years. Each of the blocks offered in Round 1.3 attracted multiple bids. Please see IFR's news release of August 26, 2016.
