Anaerobic treatment has many advantages over other biological method particularly when used to treat complex wastewater such as petroleum refinery wastewater. In this study two Up-flow Anaerobic Sludge Blanket (UASB) reactors were operated in parallel to treat six volumetric organic loads (0.58, 1.21, 0.89, 2.34, 1.47 and 4.14 kg COD/m·d) to evaluate the chemical oxygen demand (COD) removal eff...

The objective of this paper is the development and solution of nonlinear and mixed-integer (MIP) optimization models for real-world planning and scheduling problems in petroleum refineries. Firstly, we present a nonlinear planning model that represents a general refinery topology and allows implementation of nonlinear process models as well as blending relations. The optimization model is able ...

Wireless telemetry systems are now becoming a relevant topic in the field of critical process control in industrial plants and oil/gas refineries. In contrast to wire line communication, wireless links are inherently unreliable. This unreliability depends critically on the propagation environment of the radio-links as the layout of scattering objects (pipes and metallic structures) influences t...

The current paper’s aim is to determine the influence magnitude of organizational wisdom in achieving strategic foresight for Daura Refinery plant Iraqi Midland Refineries Company (MRC) through research hypothesis that suggests a lack impact on foresight. was tested using analytical descriptive method coupled with questionnaire as main tool. 59-article distributed leaders company comprised stud...

Abstract Life cycle assessments can help inform decision-making about greenhouse gas (GHG) emission reduction opportunities but are often not embraced by stakeholders associated with industries where study results highly scrutinized and contentious. This project was motivated stakeholder interest in understanding open source life models (the Oil Production Greenhouse Gas Emissions Estimator, OP...

In spite of large and increasing efforts to control major accident risk, a number of serious accidents over the last few years have shown that control still is not sufficient in some cases. Examples of such accidents within the chemical process and oil and gas industries are Flixborough Disaster, Bhopal Disaster, Piper Alpha Disaster, Phillips 66 Disaster, Sodegaura Refinery Disaster, DSM Chemi...

A model developed for multicomponent gas separation using hollow-fiber contactors permits simulation of cocurrent, countercurrent, and crossflow contacting patterns with permeate purging (or sweep). The numerical approach proposed permits simulation to much higher stage cuts than previously published work and provides rapid and stable solutions for cases with many components, with widely varyin...

the purpose of this study was to explore the impacts of: knowledge management, senior managers, staff, technology, consensus, service customization, and integration, as the factors effecting customer relationship management (crm) implementation in parsian international hotels. in this study the population was composed of parsian hotels managers and experts. due to their small number (n=53), cen...
