A unique Taylor-vortex membrane reactor (TVMR) design for continuous gas-liquid reactions is presented in this work. The consists of a cylindrical rotor inside stationary concentric vessel, and flexible system equispaced baffle rings surrounding the rotor. This restricts annular cross section to small gap between baffles rotor, divides annulus into 18 mixing zones. support 6 m long PFA tubular ...

In this study, we investigated the efficiency of dissolved methane (D-CH(4)) collection by degasification from the effluent of a bench-scale upflow anaerobic sludge blanket (UASB) reactor treating synthetic wastewater. A hollow-fiber degassing membrane module was used for degasification. This module was connected to the liquid outlet of the UASB reactor. After chemical oxygen demand (COD) remov...

The technologies most commonly used for performing secondary treatment of municipal wastewater rely on microorganisms suspended in the wastewater to treat it. Although these technologies work well in many situations, they have several drawbacks, including the difficulty of growing the right types of microorganisms and the physical requirement of a large site. The use of microfiltration membrane...

Abstract Integration of reaction and separation is attractive in production biobased oligomers short polymers from polysaccharides proteins via catalytic degradation. The challenge lies controlling the molar mass distribution. Theoretical analysis for process integration performed conventional CSTR, a multifunctional reactor, reactor-separator-recycle processes. Closed-form solutions balance eq...

Direct non-oxidative methane conversion (DNMC) is one of the most promising options to convert (CH4) in natural gas remote extraction sites liquid aromatics, which easier transport compared CH4 gas. The main constraint DNMC low conversion, and thus aromatics product yield due thermodynamic limitation. This work reports a recycle reactor/hydrogen (H2) membrane separator achieve high by circumven...

one of the most important concerns in tehran municipal landfill is the production of leachate and its potential for water resources pollution, this study was undertaken to examine feasibility of biological and physico/chemical treating of high-strength landfill leachate that was collected from tehran municipal landfill. average cod of the leachate in aerobic submerged membrane bioreactor is 68...
