More than 96% of Malawians relied on wood fuels for cooking and heating in 2018. About 4 million people now use charcoal urban areas; resulting environmental degradation, loss forests increased run off, siltation rivers depletion water resources lakes Malawi. This study assessed the potential adoption Liquefied Petroleum Gas (LPG) as an alternative fuel to firewood. A total 1200 households thre...

Reactor and reaction engineering play a vital role in petroleum and chemical processing. The aim of this article is to acquaint the reader with the interaction between reactor design=selection and the characteristics of the chemical reaction of interest. Reactor selection and design are the basis of economical and safe operation. Chemical reactions in petroleum refining include a huge spectrum ...

The prevailing treat to lives and property by the usage of gas for cooking, etc, rapidly increasing evolution in new technologies worldwide, a novel approach utilizing dual communication network providers is applied alert users event leakage Liquefied Petroleum Gas (LPG). In this work, prototype detector, based on dedicated Peripheral Interface Controller (PIC), sensitive MQ-6 sensor, GSM/GPRS ...

ZnO nanorods (diameters∼25 nmand lengths∼145-150 nm) were synthesized by using a simple solochemical method and their LPG sensing properties were investigated. The ZnO nanorods exhibited outstanding gas sensingcharacteristics such as, higher gas response (∼502 to 50ppm LPG at 300 ◦C), extremely rapid response(∼6-7 s), fast recovery (∼6–7 s), excellent reproducibility, good sensing selectivity a...

A rapid method has been developed for extracting neutral lipid from small samples of human adipose tissue, with a petroleum ether (“Skellysolve B”) as the extracting solvent. It is coupled with a simple method of transesterification, to convert the purified triglycerides to fatty acid methyl esters. Virtually no phospholipid is extracted by the petroleum ether. Analysis of the extracted lipid b...

BACKGROUND Propane, a major component of liquid petroleum gas (LPG) derived from fossil fuels, has widespread applications in vehicles, cooking, and ambient heating. Given the concerns about fossil fuel depletion and carbon emission, exploiting alternative and renewable source of propane have become attractive. In this study, we report the construction of a novel propane biosynthetic pathway in...

An explosion accident from a road tanker while carrying hazardous materials can have dangerous effect on users and the surrounding area through which passes. Based evidence of case involving reported, it shows that this cause death destruction to property. In Malaysia, several cases accidents tankers also occurred. Among methods used determine impact is use consequences analysis method. Current...

Introduction Petroleum refining utilize large quantities of water for desalting, distillation, thermal cracking, catalytic and treatment processes to produce useful products [liquefied petroleum gas (LPG), gasoline, jet fuel, diesel, asphalt and petrochemical feedstock] 1-3. Refining process generates wastewater (0.4-1.6 times the volume of crude oil processed)4. Discharge of untreated petroleu...
