Abstract Bitumen contains approximately 5 wt% sulfur so it must be removed before being used as fuel. Herein, we performed oxidative desulfurization of bitumen at room temperature using n-pentane and ultrasound to reduce viscosity mix the bitumen-dissolved aqueous reaction solution physically. The states in ratio were investigated confirm process. Additionally, developed a novel method for sepa...

In order to improve the viscoelasticity of bitumen, several modifiers were compounded with it, including SBS, reclaimed rubber powder, tackifier, plasticizer, and oil stabilizer, produce High-viscosity High-elastic Modified Bitumen (HVE-MB). The various physical rheological properties bitumen evaluated using a number factors, such as dynamic viscosity at 60 °C, elastic recovery, penetration, so...

an efficient method was employed for the ash and pyrite sulphur removal from bitumen using column flotation process. the bitumen samples containing 9.6% sulphur (6.81% in the pyrite sulphur form) and 26.4% ash were successfully showed up to 75.20% of pyrite sulphur (e.g.; 51.66% of total sulphur) and 70.81% of ash removal. the box-behnken design (bbd) was employed to design the experiments, to ...

in petrochemical industry, the production of polyvinyl chloride (pvc) is accompanied by formation of heavy end wastes which consist of a mixture of di and multichloro compounds as kind of materials which are generated in ethylene dichloride (edc) purifcation. a high quantity of chloro compounds found in the heavy end waste allows it to be polymerized with alkaline polysulfdes to form polysulfde...

Exponential deterioration in pavement caused by heavy loads, temperature variations, and rainfall had led to failure. To overcome those failures, bitumen properties needed be enhanced an economical sustainable way. Researchers have used various modifiers enhance the of virgin bitumen, but end product still does not seem accepted asphalt industry at required level. On other hand, construction co...

Production of highly viscous tar sand bitumen using Steam Assisted Gravity Drainage (SAGD) with a pair of horizontal wells has advantages over conventional steam flooding. This paper explores the use of Artificial Neural Networks (ANNs) as an alternative to the traditional SAGD simulation approach. Feed forward, multi-layered neural network meta-models are trained through the Back-...
