Biogas as used in two different systems: an instant‚ gas water-heater used to generate hot water for farm use‚ and a modified piston engine driving an electrical generator of one phase‚ I kW output‚ fuelled directed by the gas. Operation of both systems was satisfactory. The unit is being used to demonstrate the technology for potential users (mostly farm owners). Key

Greenhouse gas Greenhouse effect schematic showing energy flows between space‚ the atmosphere‚ and Earth’s surface. Energy exchanges are expressed in watts per square meter (W/m2). A greenhouse gas (sometimes abbreviated GHG) is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect.[1] The primary greenhouse gases in the Earth’s atmosphere are water vapor‚ carbon dioxide‚ methane‚ nitrous oxide‚

Gas Price Elasticity The Energy Information Administration of the Department of Energy began tracking weekly gasoline prices in 1990 by means of a survey of 800 service stations around the country. The average retail price for unleaded gasoline posted its fourth record high during the week of June 12‚ 2000‚ increasing 5 cents a gallon to an average of $1.681. The price at the pump is higher than the same period last year by 56 cents and has risen 16.2 cents over the past month (Anonymous‚ 2000)

The oil and gas industry is one of the world’s largest‚ complex‚ and expensive industry. The prices of oil and gas are probably the most closely plotted products in the global economy. In this industry there are three main segment of value chain: upstream‚ midstream‚ and downstream. It is evident that energy source play vital input to human activities‚ development‚ and growth of the economy. Hence‚ it is believed that after the industrial revolution‚ accessed clean‚ inexpensive and reliable energy

Bangladesh has always been considered a natural gas rich country. It is largely available in the eastern part of the country extending from greater Sylhet down to greater Comilla‚ Noakhali and Chittagong. It has also been discovered offshore in the Bay of Bengal. Natural gas plays an important role in the country ’s economy. It is an environment friendly fuel‚ which undergoes clean and odorless combustion. It is widely used as fuel for domestic (cooking and heating)‚ industrial (metallurgical‚ ceramic

INTRODUCTION For this experiment we studied an oxidation-reduction reaction of magnesium and hydrochloric acid solution. We compared the experimental measured amount of a product and the amount predicted by the theoretical calculation of a balanced equation: Mg (s) + 2HCl (aq) → MgCl2 (aq) + H2 (g) PROCEDURE First we obtained a strip of pre-cut magnesium ribbon‚ cleaned it with steel wool to remove any signs of oxidation from the strip (which would alter our results)‚ and then weighed it (individual

Borneol; An Oxidation-Reduction Scheme Nicolas Gibson Lab Time: Tuesday 11:30 am Abstract: In this experiment‚ the main objective was to synthesize a ketone from borneol via an oxidation reaction and secondly‚ to produce a secondary alcohol from camphor via a reduction reaction. Therefore‚ the hypothesis of this lab is that camphor will be produced in the oxidation reaction and isoborneol will be the product of the reduction reaction because of steric hindrance. For the oxidation
