Due to the lack of natural water resources and high consumption in industries, desalination systems are good options supply demands, especially regions with a crisis. If these wastes used thermal cycles, addition improving efficiency reducing energy consumption, production environmental pollutants can also be reduced. In this paper, multi-stage flash brine recirculation (MSF-BR) system Abadan r...

Reasons for Blending Crude Oils at a Refinery Oil refineries, and especially their on-process units that process the primary crude feed stocks, are not uniform in either design or operation. The refinery process units and the combination of units built and in service at a given refinery location are part of a plan to accommodate a certain slate of crudes based on their properties. These decisio...

BACKGROUND Toxocariasis is one of the most important zoonotic diseases caused by Toxocara larva stage in humans. One of the major transmission routes of infection, especially in children is pica. The aim of this topic was study the contamination of Abadan public parks with Toxocara eggs. MATERIALS AND METHODS Two hundred and ninety one samples of soil were collected from 31 parks. The samples...

The operational stability and continuity are key production characteristics of actual refinery processing units, which plays important role to safe and efficient production. While few literatures have given a sufficient and comprehensive expression of such characteristics. In view of the problem, this paper discussed refinery operations optimization based on operational stability and continuity...

The accuracy of using linear models for crude distillation unit (CDU), fluidize-bed catalytic cracker (FCC) and product blending in refinery planning has been debated for decades. Inaccuracy caused by nonrigorous linear models may reduce the overall profitability or sacrifice product quality. On the other hand, using rigorous process models for refinery planning imposes unnecessary complication...
