Abstract: The use of mixed amine system in gas treating processes is increasing today. For natural gas sweetening purposes, mixed amines are typically mixtures of MDEA and DEA or MEA that enhance CO2 removal while retaining desirable characteristics of MDEA such as reduced corrosion problems and low heats of reaction. In this work, a process simulator was used to predict the performance of an I...

Iran's proved natural gas reserves are the world's second largest reserves. Mainly, because of different climate changes and different reservoirs characterizations, studying the behavior of producing outcome fluids and their transportation, is of major interest. One of the main problems occur in the gas reservoirs is related to the hydrate formation while producing from a well, either in produc...

'Comice' is among the pear varieties most difficult to ripen after harvest. Ethylene, cold temperature, and intermediate (10 °C) temperature conditioning have been successfully used to stimulate the ability of 'Comice' pears to ripen. However, the sensory quality of pears stimulated to ripen by different conditioning treatments has not been evaluated. In this study, a descriptive sensory analys...

abstract sour cherry (prunus cerasus l.) is an important iranian-native fruit, considered highly perishable commodity which cannot be stored for any length of time. on this study, effect of three gas compositions (ambient, 5% o2+5% co2+90% n2 and 10% o2+15% co2+75% n2) and two storage temperatures (0 and 5 °c) on two sour cherry cultivars namely erdy jubileum and erdy botermo was studied in a c...

The peel components of Mandarin, Sour lemon and Sour orange were analyzed. Peel flavorcomponents were extracted using cold-press method and eluted using n-hexane. All compoundswere analyzed using GC-FID and GC-MS. Twenty-seven, Twenty-four and Twenty-nine peelcomponents were identified in Mandarin, Sour lemon and Sour orange respectively. They includealdehydes, alcohols, esters, monoterpenes an...

Natural gas is the most popular fossil fuel in the current era and future as well. Natural gas is existed in underground reservoirs so it may contain many of non-hydrocarbon components for instance, hydrogen sulfide, nitrogen and water vapor. These impurities are undesirable compounds and cause several technical problems for example, corrosion and environment pollution. Therefore, these impurit...

The research paper provides the results of investigation of “Sour-milk feed supplement” for piglets based on natural association of microorganisms Lactomyces tibeticus. It was found that probiotic microorganisms that compose sour-milk feed supplement withstand the adverse actions of gastrointestinal tract and can be easily acclimatized in the intestinal tract of piglets. Administration of sour-...

We used a next-generation high-throughput sequencing platform to resequence the Xinguowei and Shouxing melon cultivars, the parents of Fengwei melon. We found 84% of the reads (under a coverage rate of "13×") placed on the reference genome DHL92. There were 2,550,000 single-nucleotide polymorphisms and 140,000 structural variations in the two genomes. We also identified 1,290 polymorphic genes ...
