Civil/Structural Engineering for the New Cement Line, Moncada Project
FLSmidth Inc. (hereinafter FLS) is a global engineering and equipment supplier to the cement and mineral processing industries. SAXUM has been assigned to participate on the civil & structural designs for the new cement production line of Moncada, Cuba, of 3.500 TPD. The contract, dated in November 2018, agreed on granting SAXUM the engineering design for the Limestone Building (crusher), Filter Building, Raw Mill Building, Cyclone Building, Mill, Additive Intake, Coal Storage and other concrete and steel structures to be designed according to the Cuban and FLS standards.
SAXUM´s scope of work included the calculation and design of concrete foundations, concrete superstructure and primary/secondary steel structures with all their connection details for the buildings previously listed, to be entirely developed for the buildings previously listed, to be entirely developed in 3D models. These models were directly submitted by SAXUM to the steel workshops for their fabrications.
For the purpose of this project, SAXUM has assigned an experienced team of civil structural professionals and designers, related to both, the steel and concrete structures. SAXUM designs encompassed also the detailing of the concrete foundations as well as the overall integration of the structural designs with the General Arrangement drawings and existing buildings. As of November 2019, this project shows relevant progress, the most important milestones as defined by SAXUM client were fulfilled, and is very close to its completion.
Analysis of Pipe Stresses and Fracture/ Failure causes for Lithium Project in Salta,Argentina
LIVENT Corporation (LIVENT) is a leading company in lithium extraction and purification technologies. The company extracts lithium ore from el Salar del Hombre Muerto in Argentina, where the company has long-term mineral rights.
SAXUM’s scope of services in this project included the engineering for the accurate evaluation of the maximum stresses developed in the pipe during operation, the causes of the observed cracks, and the actions/reinforcements that need to be done for the appropriate operation of the pipe. The problem was based on the fact that during the operation the pipeline had a breaking point, observing deformations in the supports. Consequently, SAXUM had to study the cause of the problems and propose the optimal solution.
In this project for LIVENT, SAXUM is occurring out the following analyses and activities for accomplishing project objectives:
• Mathematical modeling of the pipe system under considering all thermal and mechanical loading. Accurate consideration of the real boundary conditions of the problem is of high importance. This analysis leads to the evaluation of the maximum stresses and deformations in the different portions of the pipe system.
• Computational Fluid Dynamical Model to determine the resulting stresses and deformations caused by the flux inside the pipe.
• Evaluation of maximum resulting stresses/deformations in the pipe system and comparison with admissible stresses of the pipe constitutive materials,
• For evaluating the maximum admissible stresses in the material that constitutes the pipe system of LIVENT in its Lithium plant, SAXUM is also performing experimental analysis based on the extension tests in both the circumferential and longitudinal directions of the pipes.
• Determine the causes of the cracks and fractures observed in the plant.
• Perform further computational analyses (static and dynamic) to identify the optimal reinforcement design of the pipe system.
• Issuing of the corresponding detailed engineering of the pipe reinforcements
• Assist LIVENT in the implementation of design solutions. As of November 2019, SAXUM has completed the activities in the four first items above. This project is planned to be completed in December 2019
Prefeasibility Study and CapEx for a New Cement Terminal
SAXUM recently undertook a project study for a client (confidential) for a new cement terminal design with a capacity of 30,000 tons of cement storage. This study required cement terminal design and operations experience including civil/structural, mechanical, and electrical engineering analysis.
The design included a comparative analysis from both technical and economical point of view, between different cement storage facilities, including silos (made of concrete and steel) and other options. The study also considered a cement unloading system from railcars, cement handling equipment, environmental controls, and all related equipment to handle, store, and distribute cement to customers. There were site-specific criteria and limitations considered including receiving and offloading of 20 cement loaded railcars per day.
The design was developed to be integrated into an existing site and operations, without disrupting those operations. This study and the subsequent design drawings showing all the cement terminal layout and structural options allowed the client to determine a site layout for optimum operations and cost-efficiency.
SAXUM will be present at the International Seminar of Gold & Silver Mining 2019
The thirteenth edition of the main metal mining symposium in Argentina will be held at the Hotel Panamericano in the City of Buenos Aires on November 26 and 27. The seminar, which takes place at a key moment at the political and economic level, will have a series of conferences and meetings for leaders and representatives of the sector where the projections of the industry and the country will be analyzed.
For this new edition of the International Seminar: Argentina Gold and Silver is expected an influx of more than 300 miners representatives, suppliers, entrepreneurs and large industries and officials from various agencies. During the event, transcendental information for the sector will be disseminated for the beginning of the new national management, as well as key data regarding the macroeconomic policies and topics that are of greatest interest to the mining sector.
