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

Background In Bangladesh‚ natural gas is one of the important sources of energy that accounts 75% of commercial energy of the country. Again‚ Bangladesh is important to world energy markets because of its large potential natural gas reserves. This resource really reduces importing fuel from other countries and saving large number of foreign currencies. All power‚ fertilizer and today the transport sector of Bangladesh are by no means dependent on Natural Gas. From the beginning of this century

Molar Volume of a Gas Objective: The objective is to determine the volume‚ of one mole of hydrogen gas at STP using experimental data‚ known mathematical relationships‚ and a balanced chemical equation. Theory: The goal of this lab is to find the volume of one mole of hydrogen at STP. The experimenters will be working with hydrochloric acid and magnesium to find the objective. The acid in this lab will react to the magnesium and cause the water in the eudiometer to rise because of the reaction

Question 1 1.1 Silica gel chromatography: This is known as the stationary phase in column chromatography. Firstly‚ the tapered exit of the column is sealed using porous material. This porous material serves as support for the packing material‚ and prevents it from exiting the pipe. Thereafter‚ silica gel is compacted into the glass pipe to make the separating column. In finishing preparation of the column‚ the solvent which is used as the mobile phase is then passed through the dry column. Then the

What is the temperature at the end of the process in (a)? (d) What is the pressure at the end of process in (b)? (e) Show both processes in the p-V plane. Problem 2: The temperature of an ideal gas at an initial pressure p1 and volume V1 is increased at constant volume until the pressure is doubled. The gas is then expanded isothermally until the pressure drops to its original value‚ where it is compressed at constant pressure until the volume returns to its initial value. (a) Sketch these processes

1) Explain why alveolar gas has a different composition from air. Atmospheric (external) air contains a high percentage of oxygen and nitrogen whereas alveoli gas contains a lower percentage of oxygen and a higher percentage of carbon dioxide. The differences in composition are due to the fact that gaseous exchange is taking place within the alveoli in the lungs. Oxygen is diffusing from the alveoli into the pulmonary artery and carbon dioxide is diffusing back into the alveoli from the pulmonary

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 reason for having a car is to get you from point A to point B and that’s it‚ no pit stops or a last minute party that you herd was suppose to be bad ass from a person you met 5 minutes ago. Gas is one of the main key for transportations but the way gas prices are going up we should just sell our cars on other things like food‚ people
