The oil refining industry is an with high requirements for process control. Nowadays, important problem the creation of concept control systems companies and enterprises. Oil one Earth's most resources. Its extraction processing have become relevant mankind. However, in modern environment, tasks extracting latest equipment, as well use cleaning minimal losses, important. This paper discusses in...

Almost all oleaginous microorganisms are available for biodiesel production, and for the mechanism of oil accumulation, which is what makes a microbial approach economically competitive. This study investigated the potential that the yeast Candida lipolytica UCP0988, in an anamorphous state, has to produce simultaneously a bioemulsifier and to accumulate lipids using inexpensive and alternative...

The increasing vehicular population causing consumption of petroleum fuels at a faster rate and causes increase in the danger of petroleum fuels depletion and the remarkable increase in high crude oil prices. The increasing consumption of petroleum products has been a matter of great concern for the country for the financial growth as well as environmental pollution abatement. The situation off...

Biodiesel has attracted increasing interest and has proved to be a good substitute for fossil-based fuels due to its environmental advantages and availability from renewable resources such as refined and waste vegetable oils. Several studies have shown that biodiesel is a better fuel than the fossil-derived diesel in terms of engine performance, emissions reduction, lubricity and environmental ...

In Brazil, and mainly in the State of Bahia, crude vegetable oils are widely used in the preparation of food. Street stalls, restaurants and canteens make a great use of palm oil and soybean oil. There is also some use of castor oil, which is widely cultivated in the Sertão Region (within the State of Bahia), and widely applied in industry. This massive use in food preparation leads to a huge a...

Waste fat produced by tanneries during the processes in which raw hide is transformed into leather represents a very important raw material for biodiesel production. However, the acid number of this feedstock usually exceeds 2 mg KOH/g, which makes it unsuitable for direct processing into biodiesel via alkali-catalyzed transesterification. An effective and economically viable pre-treatment meth...

Of the 12 billion tons of waste generated annually in the United States; less than 10% is defined as hazardous under the provisions of RCRA. This paper summarizes the data available on some of the wastes that are defined as non-hazardous. These wastes include industrial non-hazardous waste, and several types of wastes that are currently exempted from hazardous waste regulations, such as oil and...
