Intensive greenhouse agriculture annually produces large amounts of residues. The present work focused on the study dynamic adsorption cobalt from aqueous solutions over a vegetal residue intensive cultivation. influence three operating variables, feed-flow rate, inlet concentration and bed height, was analyzed. According to results, variable that particularly affected percentage adsorbed rate....

In this work, the feasibility of a novel method cryogenic carbon capture based on dioxide frost deposition onto cold moving bed is explored. As gas mixture including CO2 flows through sufficiently packed bed, deposited material as frost. warmed by stream front advances bed. Experimental measurements rate advance within static are used to set up achieve continuous removal. Precooled and dry bina...

background: the modeling aims to simulate or optimize a process in physical, chemical or biological environments and the derived model will provide a considerable assistance to generate data and predict unknown condition, in case of sufficient suitability. unsuitable disposal and elimination of waste tires have polluted the environment and human life areas, it also have caused removal of a huge...

Adsorption of gold cyanide on three types of Activated Carbons (ACs) has been investigated in batch and column adsorption conditions. Applied ACs have been derived from different crops precursors i.e., coconut shell (CAC), peach stone (PAC), and walnut shell (WAC). As peach stone and walnut shells are abundant agricultural residues in Iran, the activated carbons produced from these precurso...

Fructose is utilized as a common sweetener in many food industries. Today, a large amount of HFCS (high fructose corn syrup, an equilibrium mixture of glucose and fructose) is produced by glucose isomerase, immobilized enzymes from corn starch. There are a lot of date palms in Iran. Date is a favorable source of carbohydrates, and a suitable source for HFDS (high fructose date syrup) production...

For a packed bed in a distillation column, fmax is the maximum fractional liquid maldistribution that can be tolerated in a parallel column model whilst still being able to achieve the design separation. It was previously shown that fmax can be easily calculated from a conventional column simulation output and it is a measure of the sensitivity of a packed bed to maldistribution. In this paper,...

In this study, the removal of bromate, a regulated ozone by-product, was evaluated using strong-base anion (SBA) exchange resin in batch and column experiments. The kinetics studies mode showed that film diffusion-controlled bromate SBA isotherm Langmuir model fitted experimental results with maximum capacity 296.66 mg BrO3−/g (~1.3 meq/mL resin). fixed-bed studies, breakthrough curves were obt...
