In plant of synthesis of a nitro aromatic compound highly dangerous are obtained waste waters that contain fundamentally nitric acid. In this work is carried out the project of an efficient installation to treat this water, as much from the point of view of the personal security of the workers like of the no contamination of environment. In the work is performed a technical...
The energetic efficiency can get for oneself intervening the application of Energetic Management System (SGEn), than just like another normalized systems of management, he establishes a group of requirements to implement, to maintain and to improve continuously, with the younger investment of resources, in the younger time and the bigger efficacy. The International Organization...
"Francisco Morazán" Power Station, since it started to work, had not been object of a general inspection into the internal side of pipelines system. Metallic parts of the installation, exposed to the atmosphere, have corrosion process evidences. A study of general corrosion problems is carried out to propose adequate solutions. During a general parade of the power station...
The operation of a bioreactor requires an appropriate inoculum. So in this work were evaluate three inocula for the biotreatment of wastewater from the meat processing industry (COMCAR) "Álvaro Barba Machado": the sludge stabilization pond (L), cow manure, which is a pattern (E) and a mixture thereof 1:1 (v: v) (EL). This methanogenic activity was determined in Visser modified...
The use of ethanol as fuel is a well-known experience in the world from the same beginning of the motor cycle OTTO. In the last years the mixtures gasoline/alcohol have been developed vertiginously and Cuba studies the advantages of introducing them, applying appropriate forms of obtaining of alcohol that don't not only affect the readiness of foods, but rather it produces...
The agricultural and industrial residue management through anaerobic digestion has increased due to their growing production, low costs and high carbon content. Some fermentation technologies for solids wastes have been developed, but they are too expensive for developing countries. That is why this paper consists in assessing the application of an anaerobic digestion process for...
The following work was carried out in the Pasteurizadora belonging to the Company Products Milky River Zaza, Sancti Spíritus. Operation conditions settled down in the production to obtain a robust product, that is to say that was able to maintain their quality under you not condition favorable during their storage and it was carried out a factorial design to determine the...
This work presents the proposal of a technology able to recover the dioxide of carbon generated during the productive process of obtaining of beers in the company Brewery Hatuey of Santiago from Cuba. For the development of this work the following stages were continued: firstly, knowing the characteristics of the productive process and the antecedents of the plant installed...
This work shows the results reached in the environmental impact reduction caused by the technological stream called Slurry Preparation Plant Reject that is obtained from the limonitic mineral extracted from the lateritic orebody in Moa, Holguin, Cuba, after the installation of the Reject Circuit for the treatment of that stream. With the installation of this Reject Circuit, for...
This work deals with the technical, economical and environmental evaluation In Water Treatment Plant of the Power Generation Plant "10 de Octubre" of Nuevitas in order to have so much element of their operation and to give some alternatives for improving its behaviour. Principal results are: Process Water Chemical treatment is effective, with removal percents in range in pre...
Given the great quantity of aspects that is necessary to keep in consideration for the development of a batch process, and the complexity of this, in presently work a wide theoretical study is presented, this study allows later to develop a procedure to synthesis and optimal design of this systems. Starting from an analyzing the main characteristics; giving continuity to the...
A packed column of height 1970 mm, packing height 1200 mm and diameter 75 mm was designed. The packing were placed at random, it is of Raschig rings, ceramic and diameter 16 mm. For the selection of the packing and to fabricate the internal constituents, recommendations of the literature were considered, and the dimensions were compared with similar installations. The...
Four main groups of bacteria coexist in the anaerobic digestive process, being the most important the methanogenics, which have like habitual means the stomach of the ruminants. An originating methanogenics microbial partnership of the bovine ruminal fluid was used to investigate the influence in the characteristics of the feeding on a digester anaerobic in the depuration of...
Were characterized environmentally production processes of beers and spirits in the industry combined Hatuey Brewery - Cuba Ron, A critical analysis of the technology used currently considering the most efficient and effective way to solve environmental pollution problems associated with prevention. The characterization also included auxiliary processes essential to the...
Magnetic field extremely low frequency (60 Hz) and density 60, 70 and 80 Gauss was applied to 700 ml of fresh waterfire to 60, 67 and 74 ºGL content in fracs PET with 3 g/L chip toasted American oak (Quercus alba) obtained from the staves barrels used. The samples were treated 3 times per week (12 treatments per month) for 60 minutes, during 3 months of study of aging. The...
