Abstract The present work focuses on understanding the impact of varying thickness SnO 2 thin films its gas-sensing response. Systematic studies were conducted by X-ray diffraction (XRD) and atomic force microscopy (AFM) structural morphological properties films, which thereafter correlated for a deeper sensing phenomenon. found to be highly dependent film thickness. 90 nm exhibits maximum resp...

Abstract. Ambient volatile organic compounds (VOCs) were measured continuously from January 2018 to December 2020 at an urban site in Zhengzhou (China) investigate their characteristics, sources, atmospheric oxidation capacity (AOC), and chemical reactivity. During the sampling period, total concentration of observed VOCs was 94.3±53.1 µg m?3, alkanes major VOC species, accounting for 58 % tota...

The depletion rate of conventional petroleum fuels is very fast. Gasoline used as fuel in the SI engine. Emissions from this cause environmental pollution because it produces harmful emissions for environment such CO2, CO, HC, and NOx. Liquefied gas (LPG) has physical chemical properties that make a favorable IC engines. It can be alone or combined with gasoline some minor engine modifications....

he oil and natural gas sector is a that used with great importance for Indonesia's national development. An interesting commodity to watch out in the industry liquefied petroleum (LPG). LPG hydrocarbon has been under pressure facilitate storage, transportation, handling main ingredients consist of propane/C3, butane/C4 or can be mixed produce LPG..At this time PT. BLORA MUSTIKA does not focus o...

The world is advancing technologically in all sectors including the use gas as cooking energy. Liquefied Petroleum Gas (LPG) one of gases used for cooking. LPG by protects environment against deforestation and air pollution. But people are not very comfortable using it due to some issues related manual frame regulation that sometimes cause fire sparks, switch cylinder explosion causing many acc...

During the Deepwater Horizon disaster, a substantial fraction of the 600,000-900,000 tons of released petroleum liquid and natural gas became entrapped below the sea surface, but the quantity entrapped and the sequestration mechanisms have remained unclear. We modeled the buoyant jet of petroleum liquid droplets, gas bubbles, and entrained seawater, using 279 simulated chemical components, for ...

Building fires have become a major growing concern over time. Liquefied Petroleum Gas (LPG) is commonly used for cooking and heating, which considered fast flammable gas. The most important damage to LPG lies in its large quantities of leakage inside halls closed rooms particular. are rapid spread into very areas. In this paper, early detection the addressed by relying on technology internet th...

Refrigeration systems are common in the natural gas processing industry and processes related to the petroleum refining, petrochemical, and chemical industries. Several applications for refrigeration include natural gas liquids (NGL) recovery, liquefied petroleum gas (LPG) recovery, hydrocarbon dew point control, reflux condensation for light hydrocarbon fractionators, and liquefied natural gas...

Liquefied Petroleum Gas (LPG) or more commonly known as LPG gas is a stove fuel that comes from the results of liquefied petroleum and then put into tube, one which 3-kilogram tube. The behavior dependence on consumption cylinders people Banggai Regency can be seen use non-subsidized 3 kilogram gas, namely (±) 32. 002 people/group, second rate subsidies non-subsidies, 38. 864 units total users,...
