Vegetable Oils

There are three classical divisions of the general subject of oils, fats, and waxes will be retained: vegetable oils, animal oils and fats, and waxes. Under each of these headings the general methods of manufacture will discribe for the most important of the illustrative individual members.

The list below are indicates the yields of vegetable oils from some of the usual sources. The two general methods employed in obtaining vegetable fats and oils are expression in use. Solvent extraction has assumed importance in virtually all vegetable oil recovery plants, alone or in combination with pre-pressing. For high oil content seeds, such as cottonseed and safflower seed, usually both expression and extraction are utilized in the recovery systems for higher yields. Obtaining crude vegetable and animal oils involves primarily physical changes or unit operations, but chemical conversion are concerned in the refining and further processing of such oils.

Approximates Oil Yields of Certain Vegetable Oil Materials:
Babassu kernels: 63%
Castor beans: 45%
Corn kernels: 4%
Copra: 63%
Cottonseed: 15%
Flaxseed: 34%
Hempseed: 24%
Kapok Seed: 18%
Palm kernels: 45%
Peanuts in the shell: 30-35%
Peanuts shelled: 45-50%
Perilla seed: 37%
Rapeseed: 35%
Sesame Seed: 47%
Soybeans: 18%
Tung nuts: 50-55%

Viscose Fiber Production Process

Viscose fiber is a base material for textile industry. The first production of this kind product is in Indian than spread over the Europe and United States also in South Asia Country like in Indonesia. Viscose fiber is produced to anticipate the shortage of natural yarn for raw material to produce yarn in textile industries, beside synthetic yarn as replace natural cotton to produce fabric. This one is a simple drawing of viscose fiber production process . Viscose fiber is used to substitute the using of cotton as raw material for textile industry. Beside of cotton availability will not enough to supply market demand in the future, also cotton just available on harvesting season. If people just depend on cotton to produce textile then people will shortage of raw material to produce textile. Using viscose fiber to fulfill of textile industry will not any shortage raw material, beside the price is lower than cotton, viscose fiber also have better quality compare with synthetic fiber fo...

Sulfur

Sulfur or sulphur is a naturally occurring, yellow, water insoluble solid element. Its chemical symbol is S , its atomic number is 16 and its atomic weight is 32.064 sulfur is nonmetal and a member of the oxygen family of elements, which constitutes Group VIA of the periodic table. The discovery of sulfur predates recorded history, and the element has been used since ancient times. The early medical books of Dioscorides of Greece and Pliny the Elder mention sulfur, and fumes from burning sulfur were used in religious ceremonies and for fumigation. Alchemists recognized sulfur as a mineral substance that can be melted and burned. It was first classified as an element by Antonie Lavoisier in 1777. Sulfur Occurrence On earth, sulfur is widely distributed in its elemental state as a secondary mineral or as a volcanic deposit, as well as in combination with a number of metals. Large sedimentary deposits of the almost pure element, mainly of Tertiary age, are found in the coastal r...

Chemicals Hazard Symbol

Chemical Hazard Symbol is regulate by government and International standard to indicate the content of any container that transport that material. The regulation of chemical hazard symbol in Indonesia is made by Ministry of Environment and become update if any changes. Some of symbol of chemical hazard is shown on the picture below. Basic Shape, Size, Materials: The length of the lines making the points should be 1/3 of the height of the diamond and the width of the base should be 1/2 the length of the diamond side. Explosives, Hazardous and Toxic Chemicals Flammable Chemicals: There are two kind of these symbol type, Flammable liquid and Flammable Solid. Symbol of Reactive Hazardous Chemicals: Symbol for Toxic Waste: This is symbol that using International standard, every symbol in the plant should follow the regulation of the above size and dimension already stated by regulation. There are small symbol and big symbol of each chemical characteristic alre...
