Production of hydrogen from purge gases of ammonia plants in a catalytic hydrogen-permselective membrane reactor

Effect of methanol treatment on gas sorption and transport behavior of intrinsically microporous polyimide membranes incorporating Tröger׳s base

“…On the other hand, the H 2 solubility values were 1.3 and 0.2 cm 3 (STP) · cm -3 · atm -1 , respectively, which is more than a 6-fold difference. The majority of published research on gas transport phenomena utilizes the time-lag method and is focused primarily on the sorption behavior of relatively condensable gases such as CH 4 , and CO 2 . The present study reveals that the solubility coefficients of other gases derived from the time-lag method -2 6 -may be less reliable.…”

“…In addition, membrane systems have a small footprint, which reduces operation site requirements [2]. Established membrane gas separation processes include N 2 production from air [3], hydrogen recovery from ammonia production [4], and natural gas purification [5]. Emerging separation processes under investigation include CO 2 capture from flue gas emissions during power generation [6].…”

Ultra-clean hydrogen production by ammonia decomposition

“…P > 8.342 bar. The operating pressure selected for this study is 40.0 bar around the value given by Rahimpour and Asgari (2009). Note that this critical point needs to be identified at various operating conditions to determine the critical minimum operating pressure.…”

A comparative study of three different methods for flare gas recovery of Asalooye Gas Refinery

“…Flare gas recovery reduces noise and thermal radiation, operating and maintenance costs, air pollution and gas emission and reduces fuel gas and steam consumption. Rahimpour and Asgari (2009) investigated hydrogen production in a hydrogen perm-selective membrane reactor from purge gases of an ammonia plant.…”
