Opis:: The extraction equilibria of hypophosphorous, phosphorous and phosphoric acids with tri-n-octylamine as an extractant in toluene were measured at 303K. Under these conditions, undissociated acid (A’) reacts with the amine (B) to form various complexes in toluene. The complexes formed and equilibrium constants were estimated by a graphical analysis method. The complexes formed in these systems were found to be A’nB type species for hypophosphorous acid, A’nBm type species for phosphorous acid, (A'B)n type species for phosphoric acid, respectively. The experimental results could be explained by reaction models and equilibrium constants for each acid.

Opis:: Celem pracy było wyznaczenie krzywych równowagowych dla lotnych związków organicznych, aby rozpoznać możliwości prowadzenia procesu zintegrowanego: reekstrakcji z biodegradacją. Określono również szybkość transportu masy benzenu w kontaktorze membranowym.
The aim of this study was to determine equilibrium curves for volatile organic compounds, subsequently used for the recognition of possibilities of carried out reextraction and biodegradation as the integrated process. The mass transfer rate of benzene in a membrane contactor was also determined.

Tytuł:: Asymptotic nash equilibria in discounted stochastic games of resource extraction
Autorzy:: Balbus, Łukasz
Powiązania:: https://bibliotekanauki.pl/articles/453664.pdf
Data publikacji:: 2013
Wydawca:: Szkoła Główna Gospodarstwa Wiejskiego w Warszawie. Katedra Ekonometrii i Statystyki
Tematy:: Nonzero-sum stochastic games
capital accumulation problems
re-source extraction games
Nash equilibrium
Opis:: A class of two person nonzero-sum nonsymmetric stochastic games of capital accumulation/resource extraction is considered. It is shown that the Nash equilibrium in the discounted games has a limit when the discount factor tends to 1. Moreover, this limit is an epsilon-equilibrium in the discounted game with sufficiently large discount factor.

Tytuł:: Liquid-Liquid Extraction in Systems Containing Butanol and Ionic Liquids – A Review

Opis:: Room-temperature ionic liquids (RTILs) are a moderately new class of liquid substances that are characterized by a great variety of possible anion-cation combinations giving each of them different properties. For this reason, they have been termed as designer solvents and, as such, they are particularly promising for liquid-liquid extraction, which has been quite intensely studied over the last decade. This paper concentrates on the recent liquid-liquid extraction studies involving ionic liquids, yet focusing strictly on the separation of n-butanol from model aqueous solutions. Such research is undertaken mainly with the intention of facilitating biological butanol production, which is usually carried out through the ABE fermentation process. So far, various sorts of RTILs have been tested for this purpose while mostly ternary liquid-liquid systems have been investigated. The industrial design of liquid-liquid extraction requires prior knowledge of the state of thermodynamic equilibrium and its relation to the process parameters. Such knowledge can be obtained by performing a series of extraction experiments and employing a certain mathematical model to approximate the equilibrium. There are at least a few models available but this paper concentrates primarily on the NRTL equation, which has proven to be one of the most accurate tools for correlating experimental equilibrium data. Thus, all the presented studies have been selected based on the accepted modeling method. The reader is also shown how the NRTL equation can be used to model liquid-liquid systems containing more than three components as it has been the authors’ recent area of expertise.

Tytuł:: Mechanizmy kształtujące cenę ropy naftowej w teorii i rzeczywistości
Factors Shaping Crude Oil Prices in Theory and Practice

Tematy:: crude oil prices

Opis:: The article examines the influence of various factors on the price of crude oil according to two approaches: American economist Harold Hotelling’s rule of nonrenewable resources and a theory known as the short-term equilibrium approach. Empirical studies show that the Hotelling rule does not hold true in practice, Potocki says, because it is based on unstable assumptions. These include changing extraction costs and variable interest rates, in addition to factors such as market failure and strategic interactions. The short-term equilibrium model describes a crude oil pricing mechanism that is determined by a combination of economic, political and psychological factors among which the equilibrium of crude oil inventories plays a key role. The author is critical of the widespread use of a static resource/production ratio and argues that researchers should think over the consequences of misinterpreting this ratio and the implications of overestimating crude oil resources.
