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...
متن کاملSupply 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...

متن کاملWater Supply and Waste Disposal Systems for Arctic Communities
The special problems of providing adequate water supply and waste disposal systems for arctic settlements are examined at the community of Frobisher Bay, Northwest Territories. The two existing methods, a trucked and a piped system, are compared for adequacy, reliability and cost. A series of alternative improvements to upgrade community services is proposed. It was concluded that any of the su...
متن کاملCements in Radioactive Waste Disposal
The use of cement and concrete to immobilise radioactive waste is complicated by the wideranging nature of inorganic cementing agents available as well as the range of service environments in which cement is used and the different functions expected of cement. For example, Portland cement based concretes are widely used as structural materials for construction of vaults and tunnels. These const...
