ABOUT BUSINESS


ABOUT BUSINESS
Ben Tre was known as land of coconut trees, the largest coconut area and production in the country, there are now about 49,000 hectares of coconut yields on bonds 360 million coconut per year. Processing industry, production of coconut products is quite diverse, including dried coconut is one of the main products are high production value. At present Ben Tre province has about 20 enterprises producing dried coconut meat, and reached over 40,000 tons in 2009, generating production value about 750 billion, creating jobs for over 600 employees directly and over 2,000 workers for started processed coconut. However, like many other industries, the manufacturing process also consumption, loss of energy and raw materials, production processes are also not really fair to be operated to maximize raw material, energy and labor. Beacause of these reasons, costs of production constitutes high product cost, restricting the competitiveness of the product compared with other countries in the region. At the same time, the problem of environmental pollution as smoke fun, wastewater, solid wastes from the production process is a problem as well as other community agencies are interesting in.

With support of UBND in Giong Trom, the study for treatment of coal oven exhaust by coconut shells have recently been applied in the coal furnace sintering of Tran Huyen Khuong, private industry Huyen Khuong in Luong Phu , Giong Trom, Ben Tre. Emissions are taken from different basement of furnace coal gas through pipes into the treatment lake. Lake area can handle 4x2x1, 5m, lime water is below the water level near the exhaust hole. Spray direct rays of lime Ca(OH)2 micro escape from countless tiny holes on the water pipe located within the perimeter of the lake and emission came out from these exhaust exit. After misting systems, exhaust gas is led into the limestone blocks are humidity beneath about 10 m high exhaust pipes located at the bottom of the lake and released outside.
After processing, the emission is so little that you feel comfortable than before treatment. In terms of science, based on measurement data of toxic gases emitted from smokestacks are standard results for the construction of 100%.

Coconut Shell Charcoal

Introduction

Shell Charcoal is an important product obtained from coconut shell. Shell charcoal is used widely as domestic and industrial fuel. It is also used by blacksmiths and goldsmiths and in laundries. Shell Charcoal is also used to produce activated carbon. Activated Carbon produced from coconut shell has certain specific advantages as the raw material can adsorb certain molecular species. Shell is carbonized by using methods like pit method, drum method, destructive distillation etc. The shell charcoal is the raw material required for the manufacture of activated carbon. The shell charcoal is manufactured by burning shells of fully matured nuts in limited supply of air sufficient only for carbonisation, but not for complete destruction. The output of charcoal in the traditional pith method is just below 30 per cent of the weight of the original shells. In VietNam the average output in the traditional method has been found to be 35kg of charcoal from 1000 whole shells or about 30,000 whole shells yield 1 tonne of charcoal. Sometimes, especially when the processing is defective, the output is still lower and nearly 50,000 shells are required to produce one tonne of charcoal. To obtain good quality charcoal, fully dried, clean, mature shells should be used. Now several modern methods are in vogue for the production of charcoal. In the modern waste heat recovery unit the heat generated by the burning of coconut shells is used for drying copra and shell charcoal is obtained as by-product. A simple and efficient method adopted for the production of charcoal on cottage scale is given below.

Process (Drum Method)

A M.S. Drum kiln is used for carbonization of shells. The drum consists of three sets of six 1" dia holes provided at its bottom, middle and upper layers and a lid. A detachable chimney is provided which is installed on the lid after closing the drum. The manufacture of charcoal requires optimum carbonization of raw shells in a limited supply of air so that there is neither unburnt shell nor ash due to complete combustion. The steel drum is filled with raw shells after placing temporarily a four inch diameter wooden pole in the centre of the drum. The wooden pole is then removed, leaving a hollow space in the centre which allows the flow of smoke during carbonization. To start carbonization, a piece of burning rag is dropped to the bottom of the drum through the hollow space in the centre. When the fire is well underway, the lid with the chimney is placed into position and the upper and the middle sets of holes are closed. Carbonization which starts at the bottom progresses as it goes up as well as radially from the hollow space. When carbonization is complete in a particular zone, a persistent glow can be seen in all the six holes of a set. When the bottom most set of holes indicate this situation, the middle set of holes is opened and the bottom set closed. The stoppage of air flowing into the bottom region avoids over-carbonization in that region. The progressive carbonization results in reduction in volume of contents and therefore more shells are added from the top. When the middle region is carbonized well, the top set of holes is opened while the middle set is now closed. A further addition of raw shells is done to fill the volume reduction to maximize capacity for burning. When the top region is well carbonized, the top set of holes is also closed, resulting in complete stoppage of air inflow to the drum. The drum is then cooled for about eight hours after which the product is ready for discharge.

Noix de coco charbon de bois

Introduction

Shell charbon de bois est un produit important obtenu à partir de coquilles de noix de coco. Shell charbon est largement utilisé comme combustible domestique et industriel. Il est également utilisé par les forgerons et les orfèvres et dans les blanchisseries. Shell charbon de bois est aussi utilisé pour produire du charbon actif. Charbon actif produit à partir de noix de coco a certains avantages spécifiques comme la matière première peuvent adsorber certaines espèces moléculaires. Shell est carbonisé en utilisant des méthodes comme la méthode de fosse, tambour méthode, etc distillation destructive du charbon de bois La coquille est la matière première nécessaire à la fabrication de charbon actif. Le charbon de bois shell est fabriqué par la combustion des coquilles de noix en pleine maturité de l'offre limitée d'air suffisant que pour la carbonisation, mais pas pour la destruction complète. La production de charbon de bois dans la méthode traditionnelle est la moelle juste en dessous de 30 pour cent du poids de la coquille d'origine. En VietNam, la production moyenne de la méthode traditionnelle a été constaté que 35 kg de charbon de bois à partir de 1000 coquilles entières ou environ 30.000 coquilles entières donnent 1 tonne de charbon de bois. Parfois, surtout lorsque le traitement est défectueux, la sortie est encore plus bas et près de 50.000 obus sont nécessaires pour produire une tonne de charbon de bois. Pour obtenir du charbon de bois de bonne qualité, complètement desséchées, la coquille est propre maturité doit être utilisé. Maintenant, plusieurs méthodes modernes sont à la mode pour la production de charbon de bois. Dans l'unité de récupération de la chaleur modernes, la chaleur produite par la combustion des coquilles de noix de coco est utilisée pour le séchage de coprah et de charbon shell est obtenu comme sous-produit. Une méthode simple et efficace adoptée pour la production de charbon de bois à l'échelle chalet est donnée ci-dessous.

Processus (Drum Méthode)

Un M.S. four à tambour est utilisé pour la carbonisation des coques. Le tambour se compose de trois séries de six trous 1 dia "fourni à sa partie inférieure, les couches moyennes et supérieures, et un couvercle. Une cheminée amovible est fourni, qui est installé sur le couvercle après la fermeture du tambour. La fabrication de charbon de bois nécessite la carbonisation optimale des matières premières coquilles dans une quantité limitée d'air afin qu'il n'y ait ni shell imbrûlés, ni de cendres à cause de la combustion complète. Le steel drum est remplie de coquillages crus après avoir placé temporairement un diamètre de quatre pouces pôle bois dans le centre du tambour. Le poteau en bois est ensuite retiré, laissant un espace creux au centre qui permet l'écoulement de la fumée lors de la carbonisation. Pour démarrer la carbonisation, un morceau de chiffon de combustion est reporté au bas du tambour à travers l'espace creux au centre. Quand le feu est bien en cours, le couvercle avec la cheminée est placée en position et la partie supérieure et les jeux de milieu de trous sont fermés. carbonisation qui commence au bas progresse comme il monte ainsi que radialement à partir de l'espace creux. Lorsque la carbonisation est terminée dans une zone particulière, une lueur persistante peut être observée dans tous les six trous d'un ensemble. Lorsque le fond la plupart des série de trous d'indiquer cette situation, le Moyen-série de trous est ouvert et le jeu à fond fermé. L'arrêt d'air circulant dans la région du bas permet d'éviter plus coquillages-carbonisation dans cette région. Les résultats de carbonisation progressive dans la réduction du volume de contenu et donc plus sont ajoutés par le haut. Lorsque la région du Moyen-est carbonisé bien, l'ensemble haut de trous est ouvert tout l'ensemble du milieu est maintenant fermé. A Outre plus de coquillages crus est fait pour combler la réduction du volume de maximiser la capacité pour la gravure. Lorsque la première région est bien carbonisé, l'ensemble haut de trous est également fermé, ce qui entraîne un arrêt complet du flux d'air sur le tambour. Le tambour est ensuite refroidie pendant environ huit heures, après quoi le produit est prêt pour la décharge.
