Scheduling of crude oil operations is an important and complex routine task in a refinery. It involves crude oil unloading, tank allocation, storage and blending of crudes, and CDU charging. Optimal crude oil scheduling can increase profits by exploiting cheaper but poor quality crudes, minimizing crude changeovers, avoiding ship demurrage, and managing crude inventory optimally. In our previou...

The new Kennecott Utah Copper smelter, started in 1995, was designed to be the cleanest smelter environmentally in the world. The plant is operating at production rates above the original design capacity. Copper concentrate is smelted in an Outokumpu flash smelting furnace. Matte is granulated and processed using Kennecott-Outokumpu flash converting. Copper anodes are processed in a modernized ...

Use of gasification based on dirty fuels in markets other than syngas production for downstream chemical processes is emerging due to market changes associated with improved gas turbines, deregulation of electric power generation, as well as more and more stringent environmental regulations. Especially for the increasing quantities of opportunity fuels such as refinery residues, biomass and som...

The course of 20-year studies on the health of the population of Ptock and its neighbourhood has been discussed as regards environmental pollution generated by refinery-petrochemical plant. Analysis of environmental factors and general principles of health-promoting phenomena were of particular concern. This paper demonstrates an increase in options of environmental factors in studies on health...
