The purpose of this study is to measure the levels quality control for some crude oil products in Iraqi refineries, and how they are close international standards, through application statistical methods refineries. Where answers sample were applied a group refinery employees (Al-Dora refinery, Al-Nasiriyah Al-Basra refinery) on principles management control, according different personal charac...

The vertical motion of air that enhances or restricts the atmospheric turbulence through boundary layer is known as "atmospheric stability", in which any movement components such water vapor, aerosols, etc. are affected by stability. aim this research to test effect stability on amount downward aersols flux at 10um (PM10) emission from stacks Daura refinery, and estimated deposition dust aeroso...

Debates surrounding the greenhouse gas (GHG) emissions from land use of biofuels production have created a need to quantify the relative land use GHG intensity of fossil fuels. When contrasting land use GHG intensity of fossil fuel and biofuel production, it is the energy yield that greatly distinguishes the two. Although emissions released from land disturbed by fossil fuels can be comparable ...

In the oil industry, different oil components are blended in a refinery to fuel products. These products are transported to different harbors by ship. Due to the limited storage capacity at the harbors and the undesirability of a stock-out, inventory levels at the harbors have to be taken into account during the construction of the ship routes. In this paper, we give a detailed description of t...

We study the structure and phase behavior of asphaltenes comprised of large polyaromatic molecules in blends of naturally occurring crude oils using small angle neutron scattering (SANS). When two compatible oils are blended together, the asphaltenes remain dispersed as colloidal nanoparticles; however, when two incompatible oils are blended together, these asphaltene nanoparticles can aggregat...

This paper presents results of investigations on physicochemical treatment of vegetable oil refinery wastewater (VORW), namely acid and technological wastewater. The study has shown that VORW has a varying high pollution load (organic matter, sulfates, phosphates and chlorides) and the removal of these pollutants from acid wastewater was more effective than that from technological wastewater; t...

This paper addresses the problem of developing an optimisation model to aid the operational decision-making process in pipeline systems. The model is applied on a real world pipeline oil distribution scenario, which connects an inland refinery to a harbour, conveying multiple types of commodities. The optimisation model was developed based on mixed integer linear programming (MILP) with uniform...

This research involves the design and analysis of pinch-based water/wastewater networks to minimize water utility in the petrochemical and petroleum industries. A study has been done on Tehran Oil Refinery to analyze feasibilities of regeneration, reuse and recycling of water network. COD is considered as a single key contaminant. Amount of freshwater was reduced about 149m/h (43.8%) regarding ...

The monitoring and performance evaluation studies were carried out for an effluent treatment plant of a refinery located in the western region of India. The samples from the inlet and outlet locations of ETP were collected at regular intervals and were analyzed for different parameters. The pH, oil & grease, BOD, COD, suspended solids were found to be reduced significantly, where as the pH of t...

Modeling the dependency between stock market returns is a difficult task when returns follow a complicated dynamics. It is not easy to specify the multivariate distribution relating two or more return series. In this paper, a methodology based on fitting ARIMA, GARCH and ARMA-GARCH models and copula functions is applied. In such methodology, the dependency parameter can easily be rendered condi...
