Development of an automatic vacuum degassing system and parameters optimization for degassing process
Rapid tooling technology is regarded as an important method of reducing the cost and time to market in a new product development process. Silicone rubber mold is frequently used in indirect tooling. Automatic vacuum casting system is widely used to degas in the manufacturing of silicon rubber mold, but the cost of hardware is very expensive. A low-cost automatic vacuum degassing system is desig...

چکیده-پخش بار بهینه به عنوان یکی از ابزار زیر بنایی برای تحلیل سیستم های قدرت پیچیده ،برای مدت طولانی مورد بررسی قرار گرفته است.پخش بار بهینه توابع هدف یک سیستم قدرت از جمله تابع هزینه سوخت ،آلودگی ،تلفات را بهینه می کند،و هم زمان قیود سیستم قدرت را نیز برآورده می کند.در کلی ترین حالتopf یک مساله بهینه سازی غیر خطی ،غیر محدب،مقیاس بزرگ،و ایستا می باشد که می تواند شامل متغیرهای کنترلی پیوسته و گ...
Evaluating the Products Quality of the Vacuum Distillation Unit by Using MFCA Method
The distillation unit is one of the main units in refning companies, and it serves as the mother unit in any refnery with any degree of complexity. The optimization of this unit can increase productivity. In this study, the vacuum distillation unit of a refnery was selected as the case study. The shares of different expenses of this unit were clarifed using a novel material flow cost accoun...
متن کاملModeling and optimization of oil refinery wastewater chemical oxygen demand removal in dissolved air flotation system by response surface methodology
In this present study the dissolved air flotation (DAF) system was investigated for the treatment of Kermanshah Oil Refinery wastewater. The effect of three parameters on flotation efficiency including of flow rate (outflow from the flotation tank), saturation pressure and coagulant dosage on chemical oxygen demand (COD) removal was examined experimentally. All the experiments were done under a...
متن کاملRemoval of residual dissolved methane gas in an upflow anaerobic sludge blanket reactor treating low-strength wastewater at low temperature with degassing membrane.
In this study, we investigated the efficiency of dissolved methane (D-CH(4)) collection by degasification from the effluent of a bench-scale upflow anaerobic sludge blanket (UASB) reactor treating synthetic wastewater. A hollow-fiber degassing membrane module was used for degasification. This module was connected to the liquid outlet of the UASB reactor. After chemical oxygen demand (COD) remov...
