during natural gas processing, water in natural gas may cause to hydrates formation in pipelines which may lead to serious damages to process equipments. given the problems raised by present of water in natural gas, glycol solvent uses to remove water.in contact of glycol with gas always an amount of btex and voc absorb along with water, which on glycol recovery process, these substances separa...
In the present study, an investigation was carried out on Parvadeh coal mine in Tabas, Iran, to survey the effect of fractures on unusual methane gas emission in coal mines. This coal mine was chosen for investigating because of its high methane gas content in the coal body and available data from sensors in desired locations. Gas concentration monitoring programs were carried out at the mine s...
Background : Chronic Obstructive Pulmonary Disease (COPD) represents a major public health problem. The course of COPD is characterized by episodic periods of worsening symptoms, termed exacerbations. Supplemental oxygen should be given to patients with COPD exacerbation without causing CO2 retention. Arterial blood gas sampling is the gold standard for monitoring adequate oxygenation and for...
The requirement to monitor blood halothane levels during anaesthesia demands a method of analysis which can be completed within a matter of minutes. This is particularly true when a digital computer monitoring system is in use on-line. For this purpose the method of choice is gas chromatography. During recent years die engineering of commercial chromatographs has improved significandy and they ...
A gas chromatographic method for the analysis of 10 organochlorine pesticides in 0.5 mL of whole blood is described. Sample preparation involved an ethyl ether and hexane extraction, followed by a silica solid phase extraction cleanup. The pesticides are quantified by gas chromatography/electron capture detection. Method limits of detection ranged from 1.1 to 5.2 microg/L. The mean and standard...
