Bitumen Asphalt production

Bitumen Asphalt Production:

Material with a boiling point greater than around 500 °C we consider asphalt. Vacuum distillation separates it from other components in crude oil. The resulting material is typically further treated to extract small but valuable amounts of lubricants and to adjust the properties of the material to suit applications. In a de-asphalting unit, the crude asphalt is treated with either propane or butane in a supercritical phase to extract the lighter molecules, which are then separated. Further processing is possible by “blowing” the product: namely reacting it with oxygen. This step makes the product harder and more viscous.

we store Asphalt and transported at 150 °C. Sometimes diesel oil or kerosene we mixed in before shipping to retain liquidity. So before delivery, they must separate these out of mixture. This mixture we often call “bitumen feedstock” BFS.
The backs of tippers carrying asphalt, as well as some handling equipment, are also commonly sprayed with a releasing agent before filling to aid release. Because of environmental concerns Diesel oil not uses as a release agent.

Oil sands:

Naturally occurring crude bitumen impregnated in sedimentary rock is the prime feed stock for petroleum production from “oil sands”, currently under development in Alberta, Canada. Canada has most of the world’s supply of natural bitumen, covering 140,000 square kilometres, giving it second-largest proven oil reserves in the world. The Athabasca oil sands are the largest bitumen deposit in Canada and the only one accessible to surface mining, although recent technological breakthroughs have resulted in deeper deposits becoming producible by in situ methods.

Because of oil price increases after 2003, producing bitumen became highly profitable, but as a result of the decline after 2014 it became uneconomic to build new plants again. By 2014, Canadian crude bitumen production averaged about 2.3 million barrels (370,000 m3) per day and they projected to rise to 4.4 million barrels (700,000 m3) per day by 2020. The total amount of crude bitumen in Alberta that they could extract and they estimate to be about 310 billion barrels (50×109 m3), which at a rate of 4,400,000 barrels per day (700,000 m3/d) would last about 200 years.

Alternatives and bioasphalt:

Although un-competitive economically, asphalt can be made from non-petroleum-based renewable resources. Also can made from waste material by fractional distillation of used motor oil. That may cause premature cracking in colder climates, resulting in roads that need to be repaved more frequently.

Nonpetroleum-based asphalt binders we can made light-colored. Lighter-colored roads absorb less heat from solar radiation, reducing their contribution to the urban heat island effect. Parking lots that use asphalt alternatives are called green parking lots.

Albanian deposits
Selenizza is a naturally occurring solid hydrocarbon bitumen found in native deposits in Selenice, in Albania. The bitumen that we found in the form of veins, filling cracks in a more or less horizontal direction. Bitumen content varies from 83% to 92%, with penetration near to zero and

120 °C softening point. The insoluble matter, consisting mainly of silica ore, ranges from 8% to 17%.

Today mines exploited in open pit quarry. Many underground mines still remain viable. Selenizza produced in granular form, after melting bitumen pieces selected in mine.

Asphalt Oil & Technology of asphalt pavements by Asphalt oil started 170 years ago, with an experiment involving natural rubber. With bitumen in the 1840s , attempting to capture the flexible nature of rubber in a longer lasting paving surface. Now a days especially RPO use instead of natural rubber for bitumen rubber blend as asphalt-oil for pavement.

Nowadays the rubberize asphalt technology adopt in many other parts of the world. Taiwan is pioneer in asphalt mixtures for flexible pavement rehabilitation. Furthermore, rubberise asphalt-oil trial in Beijing and for use in new and maintenance work. As part of the preparation for the 2008 Olympics in China and it has also been used in EcoPark Project in Hong Kong.

Bitumen flux rubber blended oil

On the basis of first positive experiences also Brazil and Sudan are strongly investing in the application of this technology for road pavements. Modified bitumen increase viscosity of bitumen flux rubber blended oil should blend with penetration bitumen grades 60/70 or 80/100. In order to provide a product with a particular viscosity and other prescribed properties.

This product is well know as Extender Oil – Asphalt Oil – Bituminous Oil –  Bitumen Oil.  Modified Bitumen Oil – Asphalt Rubber Oil – Bitumen Blend Tyre Oil .

Bitumen Emulsion CSS-1

Bitumen Emulsion CSS-1

It is a emulsion Bitumen cationic slow setting asphalt emulsion produced by the patented SMEP process also bitumen emulsion is sutaible for road. However producer make The base asphalt for emulsification from specially  crude oils via carefully refining processes.  By the way Bitumen Emulsion CSS-1 components we carefully select and balance, according to formulations.

What is Bitumen Emulsion?

Emulsified Bitumen usually consists of bitumen droplets suspended in water. Moreover this dispersion under normal circumstances would not take place. Also everyone knows, oil and water don’t mix. But if an emulsifying agent added to water asphalt will remain dispersed. Most emulsions used for surface treatments. That`s enable using lower temperatures (45°C-70°C). This is much lower than 150-190°C used for hot mix asphalt cements. The lower application temperatures will not damage asphalt and are much safer for field personnel. In bitumen emulsion production, water treated with emulsifying agent and other chemicals. It pumped to colloid mill along with bitumen. The colloid mill breaks bitumen up to tiny droplets. Emulsifying agent migrates to asphalt-water interface and keeps droplets from coalescing. As a result Emulsion then pumped to storage tank.

We develop Bitumen Emulsion and exponentially increase sin that we created in 1900. Estimated presently at 20% of the global bitumen use and bitumen emulsions are basically an O/W – Oil on Water solution – A dispersion of bitumen particles on water, stabilized with the addiction of surfactants – Surface active agents – or most commonly known as emulsifiers, that will permit the bitumen to de diluted in water, however They primarily using for tack coats for use in between hot mix asphalt layers and prime coats for thin hot mix surfacing layers or a chip seal pavements.  any way Bitumen emulsion devid into 3 categories; 

Non_ionic with neutral globules 

cationic with positively charged globules

Anionic with positively charged globules

Bitumen 60-70

Bitumen 60-70:

bitumen penetration grade  is semi hard penetration grade bitumen using as paving grade bitumen suitable for road construction and repair also for the production of asphalt pavements with below technical specification. It also mainly used in the manufacture of hot mix asphalt for bases and wearing courses. Bitumen 60-70 is mostly used bitumen grade and basic material for all other bitumenious products.

Temperature vs stiffness relationship of bitumen is dependent on type of crude oil and its refining method. It used as a paving grade bitumen which is suitable for road construction and repair. It also used for production of asphalt pavements with below technical specification. This grade of bitumen is mainly used in manufacturing of hot mix asphalt for bases and wearing courses. It`s one of most used bitumen grades.

Softening point and penetration of bitumen 60/70:

Bitumen 60/70

 Globally Bitumen`s  Penetration Bitumen is pure petroleum product. It manufactured from vacuum bottom by passing hot air. Furthermore,  penetration between 60~70 desi-millimeter and softening point between 48 ~ 52C. It has a thermoplastic property which is like as synthetic resin material which gets softer with heating and hardens when cooled. This grade of bitumen 60-70 has very strong viscosity compare to other grades.

Bitumen ages:

Aging refers to changes at intervals virtues of bitumen 60/70 over time. These changes unit of measure visible as cracks or crumbling areas. Once hydrocarbon is exposed to 0.5 conditions. Bitumen 60/70 molecules react with gas, that amendment of the structure and composition of the organic compound. Mixing with gas, called-oxidation, causes it become brittle, arduous and to vary color from dark brown or black to gray. This ageing happens further oftentimes in hotter condition. Also in heat seasons, inflicting older pavements to crack further just. Condition could in addition occur wherever surface films of hydrocarbon unit of measure skinny, or if there has been inadequate compaction throughout construction.

Guaranty/warranty of Bitumen 60/70:
