Nowadays, increased attention has been focused on internal combustion engine fuels. Regarding environmental effects of internal combustion engines particularly as sources of pollution and depletion of fossil fuels, compressed natural gas has been introduced as an alternative to gasoline and diesel fuels in many applications. A high research octane number which allows combustion at higher co...

Given the critical role played by natural gas in providing electricity, heat, and other essential services, better models are needed to understand dynamics of networks during extreme events. This paper aims at establishing appropriate fast simulation capture slow linepack depletion for ideal isothermal pipeline networks. Instead solving partial differential equations (PDE) on a large scale, thr...

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...

We test for long-term damages from precipitation shocks in rural Brazil by observing wages of households that have permanently migrated from rural to urban areas. We find that large short-term precipitation shocks damage migrants’ long-term wages. We offer an analytical explanation for this outcome: credit-constrained households may be willing to accept lower wages in urban areas following the ...
