Analysis of the co-movement between Chinese and international crude oil price
Crude oil price has an important effect on national economic production and safety-stock. In this paper, we analysed the trends of Chinese and international crude oil prices and their fluctuations by testing the Granger causality and the dynamic effects to its counterpart. Results show that from 1997, the trends of Chinese and international crude oil prices are almost identical. The fluctuation ...

Biodegradation of crude oil in soil using chicken manure
To investigate enhancement of crude oil biodegradation by adding microbes to the contaminated soil, chicken manure was put into oil-polluted soil (at 10% v/w pollution level). In the soil amended with chicken manure, 72.5% of the crude oil was degraded, whereas only 52.7% of same oil was degraded in the unamended soil. The remedied soil contains 1.4 × 106 CFU g−1 crude oil-degrading bacteria, and ...

Non-linear cointegration between crude oil and stock markets: evidence from Asia-Pacific countries
This paper aims to investigate the possible linkage and non-linear interaction between crude oil and stock markets using cointegration and causality tests. Daily data on world crude oil prices and the stock indices of Japan, Taiwan, South Korea, Australia, Indonesia, India, Singapore and Malaysia are selected for this study. Unlike the previous literature, by conducting a non-linear ...

Viscosity correlations for light Omani crude using artificial neural networks
Predicting the crude oil viscosity is very crucial to the oil industry. Accurate prediction of the viscosity will lead to a better design of an energy efficient transportation system and helps in determining the enhanced oil recovery method. There has been intensive work in generating viscosity empirical correlations for under–saturated, saturated and deal oil. Due to the rapid growth in ...

The crude oil distillation unit
The crude oil distillation unit (CDU) is the first processing unit in virtually all petroleum refineries. The CDU distills the incoming crude oil into various fractions of different boiling ranges, each of which are then processed further in the other refinery processing units. The CDU is often referred to as the atmospheric distillation unitbecause it operates at slightly above atmospheric ...

Dispersant and salinity effects on weathering and acute toxicity of South Louisiana crude oil
Chemical dispersants are an important technology in the remediation of oil spills in the aquatic environment, facilitating degradation of crude oil and salinity is an important factor in dispersant effectiveness. The aim of the current study was to explore the role of salinity on the degradation chemistry of crude oil polycyclic aromatic hydrocarbons (PAH) and acute toxicity of the water ...

Techno-economic assessment of heavy crude oil desalting plant
Electrostatic desalting is the industrial standard method for removing salt from crude oil. In this study a techno-economic analysis of a crude oil desalting plant is presented. A complete process simulation was conducted using Aspen HYSYS in parallel with a simulation in Microsoft Excel in order to account for salt concentrations. An economic assessment of the proposed design was performed to ...

Crude Oil in Soil
For many good reasons are there in the moment high focus on cleaning up soil do to varies contamination over the years from example oil production or wars. One of the major cleaning projects is on the way in Kuwait, caused by the oil well fires happened during the Iraq war I 1991. Photos from the U.S. Space Shuttles (nasa.gov), show oil wells set on fire along the Persian Gulf in June 1991. ...

Impact–based cost–benefit analysis model for management of crude oil contaminated agricultural soil
Evaluating the compensation payable to farmers whose farms/farmlands have been rendered unproductive due to oil spill requires adequate scientific research and improved decision–making. This work proposes a bacterial–based mathematical framework as a decision–support system for evaluating crude oil spill impact on agricultural soil. The rate of 'in situ' biodegradation of the crude oil predicts ...

Comparative effects of biological and chemical dispersants on the bioavailability and toxicity of crude oil to early life stages of marine medaka (Oryzias melastigma)
We assessed the bioavailability and chronic toxicity of water‐accommodated fractions of crude oil (WAFs) and two dispersants plus dispersed crude oil (chemical dispersant + crude oil, CE‐WAF, and biological dispersant + crude oil, BE‐WAF) on the early life stages of marine medaka, Oryzias melastigma. Results showed that the addition of the two dispersants caused a three‐ and four‐fold increase ...

Technical note: An estimate of the effects of associated gas on the EROEI for an oil well
Previous work by the present author, cited herein, has provided estimates of the EROEI for crude oil as a function of well depth. Clearly, a factor in EROEI is well pressure due to associated gas and it is when such gas is depleted that a beam pump becomes necessary. This has been widely known since the early days of the industry and features in the 'Law of Capture'. Accordingly, in this article ...

ROAD//STABILIZR Alleviates Gravel Shortage for Syncrude - Case Study
When Base Plant Projects realized Syncrude’s road building material was in short supply, they teamed with Mildred Lake Mining to seek a solution. Did you know that the Alberta oil sands are the third-largest known source of crude oils in the world, next to Saudi Arabia and Venezuela? One of the largest producers of crude oil in Alberta is Syncrude. In 2011, Syncrude produced a considerable ...

Surface Decontamination of Crude Oil by DeconGel 1101 and 1102
ABSTRACT Surface decontamination efficacy determination of DeconGelTM 1101 and 1102 on aluminum, stainless steel, and concrete surfaces contaminated with Crude Oil (polyaromatic hydrocarbons fraction) was performed with LC/MS (Liquid Chromatography/Mass Spectrometry) according to Environmental Protection Agency (EPA) SW-846 Methods: 3500C (sampling), 8321B (analysis), and 1654A (Analysis of PAH ...

The impact of rising international crude oil price on China's economy: an empirical analysis with CGE model
Many studies, as well as historical events, indicate that oil price shocks affect the macro economy of a country. In this paper we build a Chinese Computable General Equilibrium (CGE) model, with which we simulate the impact on the Chinese economy of international crude oil price when it rises by 5%, 10%, 20%, 40%, 50% and 100%. Simulation also identifies the effects of low/medium/high ...

Is it clean or contaminated soil? Using petrogenic versus biogenic GC‐FID chromatogram patterns to mathematically resolve false petroleum hydrocarbon detections in clean organic soils: A crude oil spiked peat microcosm experiment
The Canadian Council of Ministers of the Environment (CCME) Reference Method for the Canada‐Wide Standard (CWS) for Petroleum Hydrocarbons (PHC) in Soil provides chemistry analysis standards and toxicity guidelines for the remediation of contaminated sites. However, these methods can co‐extract natural biogenic organic compounds (BOCs) from organic soils, causing false exceedences of toxicity ...

The world needs storage space for crude-oil glut
Today we are surprising with this new published in the Wall Street Journal. The crude oil storage space in U.S., Europe, South Korea, Southafrica and Japan would be expected to hit the maximum capacity due to a crude-oil production glut. For this reason, in U.S. there are spaces where crude-oil storage tanks are building, like the storage hub in Cushing, Oklahoma. Also groundwater saltmines and ...
