Caustic soda is used in the manufacture of plastic wrap, soap and paper and is the major ingredient in most oven cleaners and liquid drain cleaners. In chemical manufacturing, it is used in chemical processing, oil refining and water treatment. Commercially, Caustic is generally used as either a solid, a 50-percent aqueous solution. Caustic soda should be used with caution, as it is an alkaline corrosive that can be hazardous. When it reacts with moisture in the air, it dissolves, generating heat. This heat may cause nearby flammable materials to ignite, resulting in a fire. It should be safely stored in a dry, cool and well-ventilated place, away from oxidizing or organic materials. It should not be allowed to come into contact with metal powders or acids.
Worldwide, the major users of caustic soda are the aluminum industry, pulp & paper and the chemical industry. The main challenge of applications are water treatment and water purification, as cleaning agent, or a wide range of uses in chemical industry like starch production or for the de-sulphurization in the petrochemical industry.Three production methods are in use. While the mercury cell method produces chlorine-free sodium hydroxide, the use of several tonnes of mercury leads to serious environmental problems. In a normal production cycle a few hundred pounds of mercury per year are emitted, which accumulate in the environment.
Modern cell technology is a relatively recent innovation of Caustic. This technology differs from diaphragm cell technology in that the solutions surrounding each electrode are separated by a membrane rather than a diaphragm. The membrane is very selective and primarily allows the migration of sodium ions from the anode chamber to the cathode chamber. Saturated brine enters the anode compartment of the cell where chlorine gas is liberated. Since only sodium ions can pass through the membrane to the cathode, the cell effluent contains substantially less sodium chloride. There is no salt removal capabilities are required as in the diaphragm cell process
By product chlorine is widely used in making many everyday products and essential for a healthy human life. It is vital for water disinfection for producing safe drinking water all over the world. Chlorine is an important chemical for water purification in water treatment plants. Eighty-five percent of medicines either contain chlorine or use chlorine in the production process.Chlorine is also extensively used in the production of paper products, textiles, petroleum products, antiseptics, insecticides, food, solvents, paints, plastics, and many other consumer products.
Sodium hypochlorite is also commonly used in the pre-treatment of cooling water to prevent bio-fouling in a cooling water system which involves piping, heat exchangers, cooling towers, etc. Hydrochloric acid is a co-product in the process of cracking. Some of hydrochloric acid is used in Oxy-Chlorination process to produce Ethylene dichloride while the rest is delivered to customers in the form of 33% solution.

Charcoal making is an old and honorable trade. Its origins are lost in prehistory and the traditional methods of making it have changed surprisingly little -from ancient times till now. The only new factors are that the simple methodologies have been rationalized and that science has verified the basic processes which take place during carbonation and spelled out the quantitative and qualitative laws which govern the process.
New methods which have been introduced by royal in some parts of the developed have supplanted the old technology. Their newness does not reside in the principle of carbonation itself but in the rationalization of the use of heat, materials handling and labor and in some instances the recovery of by-products from the smoke given off during carbonisation.
New in the world of advertising is automatically assumed to mean ‘better’ it is not surprising that there has been an upsurge of interest in these new technologies by the developing world in attempting to increase the availability of charcoal and wood fuels. This Forestry Paper tries to supply a rational answer to the question:- “How can the industrial making systems make a useful contribution to charcoal production in the developing world?”
If one elects to make charcoal using one or other of the methods in this paper it will still be necessary to make use of the information in, because with the Industrial technologies about 90% of the process from the growing and harvesting of the wood to the distribution and sale of the finished charcoal is still the same as with the traditional methods. The newness resides in the carbonisation step and the replacement of labour intensive methods of materials handling with capital intensive methods.
– The yield of charcoal from the wood is higher.
– Carbonisation is more rapid.
– Charcoal can be made -from raw materials that cannot be processed by traditional methods.
– Industrial chemicals and heat energy can be recovered from the smoke given off during carbonisation.
– By recovering by-products from the smoke there is less pollution of the environment.
– The yield of charcoal is higher.
In traditional charcoal making part of the wood is burned to dry out and carbonise the remainder. During carbonisation there is also an exothermic production of heat as the wood structure decomposes to form charcoal and this supplements the heat derived from burning part of the charge. The most efficient of the retort systems described later is capable of giving yields of about one ton of charcoal from about 3.5 tons of wood providing the wood is well dried and the retort operated properly. The best that can be achieved by brick kilns is about one ton from 4.5 tons of well dried wood.

A royal tile is a manufactured piece of hard-wearing material such as ceramic, stone, metal, or even glass, generally used for covering roofs, floors, walls, showers, …Appropriate refined clay is formed to the desired shape. It is placed in a kiln, and then fired. The typical firing temperature is around 1,000 °C, though it may be as low as 600 °C. The iron content, reacting with oxygen during firing, gives the fired body a reddish color or brown. White-colored terracotta is known as pipe clay, as such clays were later preferred for tobacco pipes.

Pyrolysis differs from other processes like combustion and hydrolysis in that it usually does not involve reactions with oxygen, water, or any other reagents. In practice, it is not possible to achieve a completely oxygen-free atmosphere. Because some oxygen is present in any it’s system, a small amount of oxidation occurs. It occurs whenever food is exposed to high enough temperatures in a dry environment, such as roasting, baking, toasting, or grilling. It is the chemical process responsible for the formation of the golden-brown crust in foods prepared by those methods.
Pyrolysis offers the possibility of de-coupling (time, place and scale), easy handling of the liquids and a more consistent quality compared to any solid biomass. With fast its a clean liquid is produced as an intermediate suitable for a wide variety of applications.
Fast pyrolysis is a process in which organic materials are rapidly heated to 450 – 600 °C in the absence of air. Under these conditions, organic vapors, it gases and charcoal are produced. The vapors are condensed to bio-oil. Typically, 60-75 wt.% of the feedstock is converted into oil.
Micro credit is the extension of very small loans to impoverished borrowers who typically lack collateral, steady employment and a verifiable credit history.
Micro credit is part of micro finance, which provides a wider range of financial services, especially savings accounts, to the poor. Modern micro credit is generally considered to have originated with the Grameen Bank founded in Bangladesh in 1983. Many traditional banks subsequently introduced micro credit despite initial misgivings. The United Nations declared the International Year of Micro credit. As of 2012, micro credit is widely used in developing countries and is presented as having “enormous potential as a tool for poverty alleviation.
The origins of microcredit in its current practical incarnation can be linked to several organizations founded in Bangladesh, especially the Grameen Bank. The Grameen Bank, which is generally considered the first modern microcredit institution, was founded in 1983 by Muhammad Yunus. Yunus began the project in a small town called Jobra, using his own money to deliver small loans at low-interest rates to the rural poor. Grameen Bank was followed by organizations such as BRAC in 1972 and ASA in 1978. Microcredit reached Latin America with the establishment of PRODEM in Bolivia in 1986; a bank that later transformed into the for-profit BancoSol. Microcredit quickly became a popular tool for economic development, with hundreds of institutions emerging throughout the third world. Though the Grameen Bank was formed initially as a non-profit organization dependent upon government subsidies, it later became a corporate entity and was renamed Grameen II in 2002. Muhammad Yunus was awarded the Nobel Peace Prize in 2006 for his work providing microcredit services to the poor.
Though lending to groups has long been a key part of microcredit, microcredit initially began with the principle of lending to individuals. Despite the use of solidarity circles in 1970s Jobra, and other early microcredit institutions initially focused on individual lending. A solidarity circle is a group of borrowers that provide mutual encouragement, information, and assistance in times of need, though loans remain the responsibility of individuals.
Indeed, Muhammad Yunus propagated the notion that every person has the potential to become an entrepreneur. The use of group-lending was motivated by Economics of scale, as the costs associated with monitoring loans and enforcing repayment are significantly lower when credit is distributed to groups rather than individuals.
Many times the loan to one participant in group-lending depends upon the successful repayment from another member, thus transferring repayment responsibility off of micro credit institutions to loan recipients.
