We attempt to determine the impact of production decisions on the price of heating oil. A model for the production of distillate fuel oil is proposed. Its solution, obtained using stochastic dynamic programming, closely matches history. By perturbing the problem in a deliberate manner, we can determine the value of additional units of inventory by examining diierences in costs. Using these diie...

As is widely known, the issue of freshwater scarcity affects practically all people, and are looking for innovative workable ways to attempt solve this issue. In work, a novel method desalination proposed. The proposed system consists solar collector (PTSC), evacuated pipe (EP), condenser (CU), separation unit (SU). working principle heating feed saline water using PTSC EP controlling flow rate...

The aim of this research is to carry out the heat transfer analysis PVT hybrid active solar still (HASS) at different water depth obtain maximum output. Experimentation performed for validation thermal modeling with and without flowing water, having 0.15m in basin. During experimentation, flows above glass cover. Theoretically calculated values basin liner, temperature yield obtained using are ...

Balanced equations of a binary mixture for molecular distillation (MD) were derived on the basis of relation of heat and mass transfer in liquid films on both the evaporating and condensing surface. Effects of feed temperature and condenser temperature on film thickness, film surface temperature and concentration, degree of evaporation and concentration of distillate were analyzed for MD. The l...

A new triangular shape solar distillation system is fabricated using locally available materials by integrating with PV panel connected to DC water heater. It designed for the first time distill saline or seawater heat energy directly (to sample water) and indirectly (through heater water). The trough made of Plexiglass painted in black color which placed inside frame UPVC pipe. performance sti...

Biodiesel produced from vegetable oils, animal fats and algae oil is a renewable, environmentally friendly and clean alternative fuel that reduces pollutants and greenhouse gas emissions in marine applications. This study investigates the influence of biodiesel blend on the characteristics of residual and distillate marine fuels. Adequate correlation equations are applied to calculate the fuel ...

To examine the toxicity of cyclosiloxanes (CSs), the predominant low molecular weight cyclic silicones found in breast implants, we injected female CD-1 mice intraperitoneally with different doses of distillate (3.5-35 g/kg body weight) containing cyclosiloxane D3 (hexamethylcyclotrisiloxane; CS-D3), cyclosiloxane D4 (octamethylcyclotetrasiloxane; CS-D4), cyclosiloxane D5 (decamethylcyclopentas...

background  apnea is one of the most common problems in preterm neonates. this study aimed to evaluate the effectiveness of aromatherapy on the reduction of apnea, bradycardia, and pulse oximetry (spo2) in premature infants. materials and methods in a clinical trial study, 60 preterm neonates randomly divided in two groups and exposed to aromatherapy with rosa damascenes distillate or distilled...

12 Some guidelines to evaluate distillation columns, considering only basic 13 thermodynamic data and principles, are provided in this paper. The method allows a 14 first insight to the problem by simple calculations, without requiring column variables 15 to ensure rational use of energy and low environmental impact. The separation system is 16 approached by two complementary ways: minimum and ...
