abstract: there is always a need to increase a distillate output of solar still. if plates will be used inside solar still then distillate output of solar still are expected to increase. hence, an experimental study is conducted to improve distillate output of basin solar stills by increasing the effective surface area with the help of different plates. for the purpose of experiment, three sola...

A silicon-based microscale distillation chip was fabricated consisting of a micro-channel 600 μm in width and 40 cm in length. Micropillars were incorporated in the micro-channel to direct liquid flow from the cooled to the heated end by capillarity. A feed of a 19 mol% acetone-water mixture was separated to 95+ mol% acetone in the distillate and 11 mol% in the bottom stream. This distillation ...

For the purpose to reveal the substance as the source of offensive odor of the fish from the sea facing petroleum and petrochemical industries, analyses have been made on the sea water, industrial wastes, offensive odor fish meat and the eels kept in the sea or industrial waste for a certain period, by means of gas chromatography, infrared, and ultraviolet absorption spectrophotometries and mas...

Production of renewable commodity chemicals from bio-oil derived from fast pyrolysis of biomass has received considerable interests, but hindered by the presence of innumerable components in bio-oil. In present work, we proposed and experimentally demonstrated an innovative approach combining atmospheric distillation of bio-oil with co-pyrolysis for mass production of renewable chemicals from b...

The occurrence of blindness after drinking some herbaceous distillates is created some anxieties in Iran. In this study, the effectiveness of concentration of Khalvash distillate was studied on the function of the new modified suggested chromotropic acid method for qualitative detection of methanol. For this purpose, three samples of Khalvash distillate were purchased from vendors of Rasht. Acc...

Heavy vacuum gas oil (HVGO) is a complex and viscous hydrocarbon stream that is produced as the bottom side product from the vacuum distillation units in petroleum refineries. HVGO is conventionally treated with thermochemical process, which is costly and environmentally polluting. Here, we investigate two petroleum biotechnology applications, namely valorization and bioupgrading, as green appr...

Number of plants and animal derived materials were reported to have antioxidant and antimicrobial activity. The present study relates to such precious and holy animal derived material cow urine, which has these activities. Antioxidant activity was done using two in vitro models, DPPH radical scavenging activity and Superoxide scavenging activity. Ascorbic acid was used as the reference standard...

The repellent activity of methanol extracts from 23 aromatic medicinal plant species and a steam distillate against female blood-starved Aedes aegypti was examined in the laboratory by skin test and compared with that of N,N-diethyl-m-toluamide (deet). Responses varied according to plant species. At a dose of 0.1 mg/cm2, the repellency of extracts of Cinnamomum cassia bark (91%), Nardostachys c...

Topical application of certain petroleum middle distillates (PMD) to mice produces skin tumors after long latency, and initiation/promotion protocols indicate that this effect is associated with their tumor promoting activity. Since induction of sustained, potentiated epidermal hyperplasia is predictive of promoting activity, five compositionally distinct PMD [hydrodesulfurized kerosene (API 81...
