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...
For their high content of fermentable sugars and their extraordinary readiness, among other many reasons, is the biomass lignocelulósica the matter excellence cousin for the production of ethanol fuel, which is considered as a cleaner alternative to the fossil fuels. In this work are treated some of the challenges that faces the production of this renewable fuel, derived of the...
The present research paper studies the rheological properties of limonitic suspensions in the ore feed to the Pressure Acid Leach (PAL) process in Moa. Two ore samples with significantly different chemical characteristics were selected. The samples were collected in Moa Oriental ore body (Area #30) and Moa Occidental ore body (Area # 12) in order to prepare the required ore...
The use of conceptual maps constitutes a valuable didactic tool, being able to apply in all the phases of the educative process; they have showed to be an effective instrument in learning and evaluation context. However, there are some issues to resolve to achieve the correct use of the concept maps, since many buildings tend to be more descriptive than explanatory. In order to...
In this work the mathematical modelling of the equipment of heaters area of a sugar factory is presented, that was used for the elaboration of a computation program that allows the design of this equipment, the simulation of the operations that happen in them, as well as, to analyze the influence of the variables involved in the process. The results calculated by the program with...
The anaerobic digestive process is a natural biological process in which an interlaced community of bacteria cooperates to obtain stable and auto-regulated fermentation, transforming the residual organic matter into biogas. In the process four main groups of bacteria coexist, being the most important methanogenics, which have like habitual means the stomach of the ruminant. In...
This work consist of the identification of an interval of trust, starting from the data of the operation of a process that it allows to predict the pH values obtained in a sequence of continuous reactors with agitation connected in series, in the one that non catalytic liquid-solid reaction systems, used for the neutralization of sour liquors in the Company "Comandante Pedro...
In this work the results of the study of characterization of the serum of Santiago´s White Cheese are presented. To know their properties they were carried out different sensorial and physical-chemical analysis according to the norms settled down in the rehearsal methods. The carried out determinations were: content of proteins, fat, density, acidity and total solids; these...
Nowadays, the concepts of sustainability have received a great deal of emphasis within the scientific world. This article explores one aspect of sustainability in the context of industrial ammonia refrigeration systems. In this paper evaluate one heat exchanger operate as heat recovery in refrigeration industry. Heat recovery as gathering and using thermal energy that normally...
This work is in the Production Plant of Chemical Bioactive Center, which plays an important role in producing active pharmaceutical ingredients and additives for culture media for use in drug production and agriculture respectively. Cleaner Production and Environmental Management System allowed the implementation of environmental policies and standards, reduce operating costs...
The biomass gasification is one way energy conventions which maintain in phase the investigation and development with some application in the electrical generation. The scientific investigation activity about theme hit the center away improvement a design; modelation and evaluation of different type the gasifiers, the practical applications carry out through small and middle...
The influence of formulation’s sustrates of coffee pulp with cedar chip, coconut and cocoa shells in the edible mushrooms production was investigated, using two strains of Pleurotus ostreatus and solid-state fermentation (SSF) techniques as an efficient biotechnological process for Pleurotus cultivation, because this technique every day is more used for agricultural wastes...
We analyze the results achieved using a pre-leaching stage in the preparation of carbonized coconut shell, to obtain activated carbon by physical activation method with carbon dioxide as activating agent at different times of activation. The leaching step included the magnetic treatment of the leaching solution of sodium hydroxide used. The results showed that the leaching stage...
