production ofdimethyl amino ethanol (dmae) and effective parameters on efficiency and purity of the chemical were studied in this article. dimethylation of ethanol amine using aqueous formaldehyde in the presence of formic acid was applied for production of dmae. results showed that four parameters such as outlet temperature of co2 gas, reflux temperature, reflux time and extraction solvent wer...

This article addresses the development of a bench-scale test (jetfire lab) mimicking fire exposure large-scale jetfire facility. An experimental approach was addressed to develop direct correlation and validate similitude between jetfire. Comparisons were made by testing Zaltex passive protection material in form panels. Novel setups designed make lab able measure time/temperature curves simila...

In this paper, a laboratory chemical vapor deposition (CVD) reactor is described, which features an opposing screw rotating fluidized bed. The efficiently concentrates powdered reactants in the reaction zone while maintaining fluidization independent of powder properties. This allows for lab-scale CVD processing many small samples at high yields and without need re-adjustment parameters differe...

the main purpose of this investigation is to study the effect of near miscible co2 injection in different porous mediums on both lab and field scales. this effect can be traced by the change of two-phase gas-oil relative permeability curves. in this work, the experiments have been performed on three rock types (i.e. sandstone, dolomite, and artificial fractured sandstone) based on an incrementa...

This review provides a comprehensive overview on the quickly developing field of polymeric hollow fiber (HF) nanofiltration (NF), including membrane (module) and process design, operational parameters, full-scale applications. Six different methods are currently used to produce HF NF membranes: phase inversion, interfacial polymerization, grafting, coating, polyelectrolyte multilayers (PEM) che...
