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...
Liquid effluents have been treated by electrocoagulation (EC), obtaining encouraging results in the removal of contaminants. The aim of this study was the application of the EC for the treatment of acid whey with reduced organic loading . Whey were analyzed for their pH, pZ, isoelectric point and COD. We used a batch-type electrochemical reactor of 2 L and a study volta and...
This work takes place in the Siboney Company in the province of Camagüey, in order to analyze the termoenergetic system of it and determine the efficiency of investments. Was evaluated the generation steam area through energetic and exergetic balances expressing their current behavior. Thermoenergetyc system was study by simulation, obtaining results of many indicators. In...
With the purpose of extracting pectin starting from the dry orange husk, to laboratory scale, for medical uses, were carried drying experiments in a solar dryer of type cabinet built in the Center of Investigations of Solar Energy. The experiments were carried in the time of crop of the orange (November - April) of the year 2009 - 2010, with the purpose of determining the...
The importance of pH mensuration during product liquor distillation coming from ammonium carbonates leaching of nickel Was studied. The evaluation Was carried out in a column of industrial distillation, operated by means of Supervisory Control and Data Acquisition EROS. The range of fed liquor Was 25 m3/h and of temperature at the top, 10 ºC. The ammonia concentration Was...
The department is conducting the study to obtain activated carbon from biomass and coconut shell charcoal from coconut shells to later be used in environmental remediation processes. This work aims to analyze the behavior of the adsorption of nickel and cobalt ions using pyrolyzed coal and coconut shell sulfate solutions of both metals to different conditions of pH and initial...
In this paper the chemical refining of Jatropha Curcas L vegetable oil before the tranesterification process to obtain biodiesel and base oil to the formulation of the lubricants oil was developed. The objective is to determinate physic-chemistry properties of Jatropha curcas L. vegetable oil (degumming and neutralized). The characterization analysis, include tests of parameters...
Presently work is carried out the mathematical model to simulate the thermal behavior of a solar distiller of tray by means of a system of three ordinary differential equations of which its solution is obtained, the one that allows to know the values of the temperature in the cover, the water to distill and the distiller’s tray through the day, as well as you can also determine...
In the initial studies of a strategy of environmental technology assessment of the project of a technology for Urea production in the region of Calicito, at Cienfuegos bay; the contamination for CO2, caused by the emission of a considerable surplus of the gas the main is identified as the main environmental impact. The result of the technological assessment is a project for the...
This work deals with a preliminary study about sedimentation step in sugar mill production process effects in Siboney enterprise molasses, Sibanicú municipality, Camaguey province, when secondary juice is used for obtaining animal foods, and sugar is obtaining by using primary juice. Sedimentation studies in different kinds of juices (mixing, primary, and secondary juices) were...
Integration tools are applied to the process of sugar production, identifying the losses of thermal energy. Energy integration is carried out of the evaporators system and pans. It is obtained that in this process there are an inefficient use of the energy, as well as there is not an appropriate use of currents with thermal quality. Energy balanced scheme and with a minimum...
In front of a dynamic and competitive environment, today’s Industrial development its headed more than never to a sustainable development demanding this way from the productive point of view the use of cleaner technologies or alternatives that improve the quality of the processes. The use of procedures for handling residual liquids is avariation that allows to achieve...
Acid treatment in oil wells is one of the most corrosive technologic process for metallic installations, since it involves concentrated acid solutions, high temperature under long exposure periods amongst others. It is imperative the use of corrosion control methods, being the most adequate and common the use and addition of inhibitors in the acid environment, the world over...
