Geochemistry Software
Contents. History The GWB package was originally developed at the Department of of the over a period of more than twenty years, under the sponsorship initially of a consortium of companies and government laboratories and later through license fees paid by a community of users. In 2011, the GWB development team moved to the Research Park at the University of Illinois, where they operate as an independent company named Aqueous Solutions LLC. Since its release, over 3,000 copies have been licensed in 64 countries.
In 2014, a free Student Edition of the software was released. An early version of the software was one of the first applications of, the predecessor to today's, to geological research. The current release is, and as such retains features of the early parallel vector architecture. Overview The GWB is an integrated package used for balancing, calculating stability diagrams and the states of natural waters, tracing reaction processes, modeling reactive transport, plotting the results of these calculations, and storing the related data.
The Workbench, designed for personal computers running, is distributed commercially in three packages: GWB Professional, Standard, and Essentials, as well as in the free. GWB reads datasets of (most commonly compiled from 0 to 300 °C along the steam saturation curve) with which it can calculate chemical equilibria. Thermodynamic datasets from other popular programs like PHREEQC, WATEQ4F, and Visual MINTEQ have been formatted for the GWB, enabling comparison and validation of the different codes.
WinRock is a petrology/geochemistry program for Windows. WinRock plots IUGS igneous classification diagrams, including QAPF diagrams, plus sandstone, general purpose. Why Crown Geochemistry? This company is completely structured around delivering this data set. We don't do anything else. We have done (as an informal estimate) more. Geochemical modeling is the. Recent improvements in the power of personal computers and modeling software have made. Reviews in Mineralogy and Geochemistry.
The program K2GWB (log K to GWB) was written to generate thermodynamic data for GWB under pressures and temperatures beyond the limits of the default datasets. The GWB can couple chemical reaction with to produce simulations known as. GWB can calculate flow fields dynamically, or import flow fields as numeric data or calculated directly from the hydrologic flow code. Uses in science and industry working in the field, office, lab, or classroom store their analyses, calculate the, create plots and diagrams, evaluate their experiments, and solve real-world problems. The software is used by, and remediators to gain quantitative understanding of the chemical and microbiological reactions which control the fate and mobility of contaminants in the biosphere.
With this knowledge, they can develop predictive models of contaminant fate and transport, and test the effectiveness of costly remediation schemes before implementing them in the field. Within the energy industry, and developers use the software to search for resources, optimize recovery, and manage wastes, all while using safe and environmentally friendly practices. Geocientists manage the side effects of energy production in projects and in the design of. Uses in education Hundreds of scholarly articles cite or use GWB and several textbooks apply the software to solve common problems in environmental and, the, and. Students can save time performing routine but tedious tasks that are easily accomplished with the software. Instead of balancing chemical reactions and constructing by hand, for example, students can spend time exploring advanced topics like, theory,.
Students can apply for a free download of The Geochemist's Workbench Student Edition from the developer's website. Other geochemical modeling programs in common use.,. CHILLER.
