A modified batch reactor system to study equilibrium-reactive transport problems

Journal of Contaminant Hydrology, 2012
It is difficult to design column experiments to study transport processes involving slow geochemical reactions that require long residence times to reach equilibrium. We propose a sequential equilibration reactor (SER) setup to study such equilibrium geochemical reactive transport problems.

Using Nonequilibrium Thin‐Disc and Batch Equilibrium Techniques to Evaluate Herbicide Sorption

Journal of Environmental Quality, 2003
ABSTRACTNonequilibrium disc‐flow techniques may better reproduce dynamic soil–pesticide interactions than traditional batch sorption studies. Batch kinetic and equilibrium experiments and dual‐label thin‐disc flow experiments were conducted with atrazine (6‐chloro‐N‐ethyl‐N′‐isopropyl‐1,3,5‐triazine‐2,4‐diamine) and imazaquin [2‐(4,5‐dihydro‐4‐methyl‐4‐

Uncertainties of geochemical modeling during CO2 sequestration applying batch equilibrium calculations

Environmental Earth Sciences, 2011
One of the uncertainties in the field of carbon dioxide capture and storage (CCS) is caused by the parameterization of geochemical models. The application of geochemical models contributes significantly to calculate the fate of the CO2 after its injection.

Non-equilibrium effects on fast reactions in a heterogeneous batch reactor

Chemical Engineering Science, 2005
Abstract Recent studies by the authors of the heterogeneous catalysis of fast binary reactions have taken a dynamical systems approach, assuming that fast enough reactions are confined to a manifold upon which surface equilibrium holds. This approximation makes substantial simplification possible, for instance in the case of a batch reactor, it ...

Neural Architecture Selection as a Nash Equilibrium With Batch Entanglement

IEEE Transactions on Neural Networks and Learning Systems
Modeling the architecture search process on a supernet and applying a differentiable method to find the importance of architecture are among the leading tools for differentiable neural architectures search (DARTS). One fundamental problem in DARTS is how to discretize or select a single-path architecture from the pretrained one-shot architecture ...

Modeling Batch Equilibrium and Kinetics of Copper Removal by Crab Shell

Separation Science and Technology, 2003
The adsorption characteristics of copper from aqueous solutions on crab shell were determined by batch tests. The uptake equilibrium and kinetics were affected by the pH of the sorption system. In the pH range of 3 to 6, the extent of copper removal was found to increase with increasing pH.

A comparison of the visking membrane and batch sephadex methods of equilibrium dialysis

Journal of Steroid Biochemistry, 1977
A comparison of the batch Sephadex method of equilibrium dialysis with the classical Visking membrane method reveals that binding affinity values for the former are 20–30% lower than for the latter under a variety of experimental conditions in the interaction of testosterone with three batches of crystalline human serum albumin.

Equilibrium Model for Cadmium Adsorption by Green Algae in a Batch Reactor

Journal of Environmental Engineering, 2002
This paper reports the results of a study on the equilibrium behavior of cadmium adsorption by a tropical, indigenous single-cell algal species, identified as Oocystis sp., in a static reactor. An exponential equation, in the form of Ce /C05a exp(bM/C0), was found to be statistically significant in expressing the relationship between the ratio of ...
