This research thesis validates the potential of tall oil as a renewable feedstock for the production of base-chemicals, especially olefins, as conceived in the thermo-chemical bio-refinery concept. The focus was on the use of hydrotreating and steam cracking technologies with different tall oil feedstocks. Particular advances were accomplished in terms of technology development for high yield o...

Xylanase (EC 3. 2. 1. 8), hydrolyzes xylo-oligosaccharides into D-xylose and required for complete hydrolysis of native cellulose and biomass conversion. It has broad range of applications in the pulp and paper, pharmaceutical and Agri-food industries. Fifty fungal species were isolated from the fouled soil around an oil refinery and screened for the production of xylanase enzyme by enrichment ...

Oil terminals are widely used to store various liquids and gases. The refinery scheduling problem is one of the most challenging problems in operational research due to the complexity of the refinery scheduling operations and the corresponding process models. In this paper, we present a model by which a decision maker should be able to choose the optimal number of tanks, tank size and truck arr...

In this paper, we demonstrate the functionality and functionalisation of waste particles as an emulsifier for oil-in-water (o/w) and water-in-oil (w/o) emulsions. Ground coffee waste was chosen as a candidate waste material due to its naturally high content of lignin, a chemical component imparting emulsifying ability. The waste coffee particles readily stabilised o/w emulsions and following hy...

A potential degrader of paraffinic and aromatic hydrocarbons was isolated from oil-contaminated soil from steel plant effluent area in Burnpur, India. The strain was investigated for degradation of waste lubricants (waste engine oil and waste transformer oil) that often contain EPA (Environmental Protection Agency, USA) classified priority pollutants and was identified as Ochrobactrum sp. C1 by...

The effects of the energy crisis and rising demand have sparked development to improve efficiency in using fuel oil. According Indonesia's oil resources, increasing refinery capacity building mini refineries is essential secure local production. It more effective cost-effective construct a small with configuration starting flash unit or pre-fractionator, an atmospheric distillation unit, vacuum...

The research was carried out to assess heavy metal presence in borehole water used eleme Port Harcourt Refinery host communities Rivers State. physicochemical parameters determined include: Temperature, pH, turbidity, alkalinity, and total dissolved solid (TDS) using conventional equipment standard laboratory procedures, also the concentration of Pb, Hg, Fe, CD, SO4, SO3, CO3 Cl-, were Atomic A...

The environmental performance of industrial anaerobic digestion (AD), pyrolysis, and integrated system (AD sequence with pyrolysis) on food waste treatment were evaluated using life cycle assessment. The integrated treatment system indicated similar environmental benefits to AD with the highest benefits in climate change and water depletion in addition to the increased energy generation potenti...
