Under the present maintenance condition in petroleum refinery facilities.

Wireless Technologies for Condition-Based Maintenance (CBM) in Petroleum Plants

Wireless devices and systems have been deployed in many communication sectors but have not yet been adequately adapted to harsh industrial environments. Cost effective, reliable and scalable wireless technologies have yet to be introduced in industrial plants, including petroleum plants. At this time, there are very few, if any, cost-effective Commercial-Off-The-Shelf (COTS) radios available th...

Anaerobic Treatment of Petroleum Refinery Wastewater

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...

Supply Chain Optimization of Petroleum Refinery Complexes

Production planning is a very important step in managing the operation of a single refinery and their complexes. Despite its significance, few contributions have been found in literature and the existing ones rely on linear models. Pinto et al. (Comp. Chem. Engng. 24, 2259-2276, 2000), presented a superstructure that represents a general topology and allows the implementation of nonlinear proce...

An epidemiological study of petroleum refinery employees.

A cohort study of 14179 current and former Chevron USA employees at the Richmond and El Segundo, California, refineries was conducted. The cohort consisted of everyone working at either refinery for a minimum of one year. The observed mortality of the cohort, by cause, was compared with the expected based on the United States mortality rates, standardised for age, race, sex, and calendar time. ...
