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...
The aim of this study was evaluated the anaerobic degradation of acid whey and the whey obtained from the elaboration of cottage cheese, for the methane production with UASB reactors operated to 1 day of HRT. Two reactors of 2,5 L were inoculated with sludge from a wastewater treatment plant of a cheeses factory. The reactors were operated during 84 days (whey of cottage cheese...
The combined industrial Hatuey Brewery, Cuba Ron is the land-based point source with the highest organic loading contributes to the Santiago Bay (41,55 %) by the river kharaj, according to research conducted by various researchers and specialists supported by CITMA causing damages to the water quality of both receiving bodies. 4 alternatives are proposed for the minimization of...
During a year of mining and industrial operations in which instabilities occurred in both links of the process, at a nickel plant with Caron technology; efficiency problems occurred, the origin of this situation was not known clearly and there were doubts about the quality materials supplied, it was estimated that the introduction of atypical minerals were the cause of the...
This work was carried out in the Provincial Company of Metal Forming and Materials of Construction (METALCONF), located in the municipality of Placetas, Villa Clara province, in collaboration with its Research and Development department, consists of a detailed study of the dangers involving the manipulation and storage of raw materials used in the process of obtaining aluminum...
This project is based on the current situation of the water treatment plant analysis at the Rum Caney Factory in Santiago de Cuba city, doing algorithms and automatic programming that will controlled the process of this plant, in ladder contact language. Due to the existing operational situation of the plant and the current tendencies in the world on the topic, this work will end...
The objective of the work has been to evaluate technical, economical and environmentally, the stock preparation investment project at the Pulpa Cuba Paper Mill. To reach this objective a comprehensive methodology of technology assessment is applied, in which, methods are used for equipment and ancillary systems design control. By economic evaluation, benefits in energy and water...
On the base of a two-dimensional mathematical model and software based on him, conceived to simulate the operation of the reactors used in the production of Hydrogen, by the catalytic steam reforming of LPG, several simulation studies they have been developed, using as source of information the data of the industrial operation. In this work the results are presented of one of the...
In this paper it is showed the industrial evaluation of yeasts Saccharomyces cerevisiae HB, S. cerevisiae C3 and S. cerevisiae Santa Cruz in the George Washington distillery. It is reported the average values of the alcoholic percentage in fermented liquor, efficiency of the fermentation and yield alcohol-substrate. The best results are archieved with the use of the Saccharomyces...
A preliminary quantitative estimation of biomass microalgae index production it is presented in this paper, for which the stoichiometric coefficients of photosynthesis reaction were calculated under different considerations. Nine alternative of equations were evaluated, where the CO2 is used as sole carbon source; the ammoniac (NH3) and the ammonia nitrate (NH4NO3) as nitrogen...
This work was done with the aim of developing a methodology to study the kinetics of flocculation, the floc properties and the predominant mechanism of flocculation in suspensions of lateritic minerals. Were used synthetic organic flocculants, marketed by the company CIBA, and was applied Smoluchowski kinetic model to study the processes of flocculation, deflocculation and...
Industrial scale Fix Bed Bioreactor performance simulations, that establish a base for the proteic sugar cane bagasse enrichment, employing a phenomenological model, is the main objective of this investigation. The product selected as study case is the same was developed by Ramos ENT#091;1ENT#093; in his doctoral thesis, named BAGAMES, mainly compose by Siboney Sugar Industry...
The chemical engineer main objective is produce chemical and biochemical products with the require quality, the cheaper price, security the most and the less ecological impact. Taking into account, the labor-research relations have been a necessity by the work characteristics: the professional always study the process like the hole, however, until the National Career Direction...
