the purpose of this research is to evaluate the effectiveness of implementation quality management system (iso 9001:2000) in gas processing plants of national iranian gas company using balanced scorecard approach. more specifically, we chose the balanced scorecard framework to examine five well-known gas processing plants in national iranian gas company from four different perspectives in order...
â performance and capacity of sulfur recovery unit (sru) are greatly affected by the h2s:co2 ratio of the acid gas stream. the acid gases in iran contain around 35 mol% h2s and 60 mol% co2. this low concentration of h2s calls for more complex sulfur plant, larger equipments, and higher costs. acid gas enrichment processes (age) is run to upgrade low quality acid gas collected from gas treating...

Our industry commonly expends a great deal of energy on determining the concentrations and how to remove CO2 and H2S from sour natural gas in the design of a gas treating and processing facility. Their presence normally drives the size and cost of much of the facility. However, troublesome trace contaminants such as mercury (Hg), carbonyl sulfide (COS), mercaptans (RSH), and aromatics (...
In the current work, a framework is presented for amine solvent selection in gas treating process. Since the appropriate decision making in this field affects the capital and operational costs, multi attribute decision making (MADM) techniques were used to rank alternatives. The determination of criteria and alternatives is the most important aspect in the MADM. Criteria were divided into two c...
two experiments were conducted to evaluate the crude protein fractionation, in vitro gas production and the biological effects of tannins in alfalfa silage treated with different levels of pistachio by-products (pb) extract. pb was soaked in water with a ratio of 1:5 (w/v) for 12 h. after filtering and concentrating, the crude extract was added to fresh alfalfa to a final concentration of 1%, 2...
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...

Hydrocarbons are sparingly soluble in aqueous solvents and to a first approximation their solubility can be described by the traditional Henry’s Law, which linearly relates the mole fraction in water to gas-phase partial pressure. The presence of amines in the aqueous phase increases hydrocarbon solubility over that in water, an effect referred to as “salting-in”. Commercial amine treating solu...
