Volumetric Effects in Coal Sorption Capacity Measurements ...

Many types of materials e.g., rubber, polymer, coal, change their volume and structure after absorption of gaseous and liquid substances. Various kinds of volume changes affect the accuracy of absorption measurements by gravimetric and manometric methods, the two major techniques currently employed. The errors associated with the volumetric effects, specifically, the case of carbon dioxide ...

Gas Sorption and the Consequent Volumetric and ...

Experimental and numerical investigations were conducted to study adsorption and desorption of pure and multicomponent gas on coal, and the sorption-induced volumetric strain and permeability change of the coal. This paper presents the experimental work. Using CO $$_2$$, N $$_2$$, and CO $$_2$$ and N $$_2$$ binary mixtures of different composition as injection gases, the measurements were ...

Volumetric Modular - Offsite Hub

Volumetric modular units are large building elements that can be linked together to form complete buildings without the need for additional superstructure. The internal fit-out, finishes and building services are pre-installed and commissioned in the modules prior to leaving the factory ensuring that defects are minimised and quality control is very high.

Volumetric Measurements of Methane-Coal Adsorption and ...

This study presents the effects of equations of state (EOSs) on methane adsorption capacity, sorption hysteresis and initial gas reserves of a medium volatile bituminous coal. The sorption experiments were performed, at temperatures of 25 °C and 40 °C and up to 7MPa pressure, using a high-pressure volumetric analyzer (HPVA-II). The measured isotherms were parameterized with the modified ...

volumetric analysis | Definition, Uses, & Facts | Britannica

Volumetric analysis, any method of quantitative chemical analysis in which the amount of a substance is determined by measuring the volume that it occupies or, in broader usage, the volume of a second substance that combines with the first in known proportions, more correctly called titrimetric analysis (see titration).. The first method is exemplified in a procedure devised by a French ...

Effects of CO2 adsorption on coal deformation during ...

The difference in volumetric strain induced by adsorption of carbon dioxide and methane is most pronounced for micropores (≤2 nm), where the volumetric strain difference can be as large as 1.7% in the case of a 0.7 nm pore at 100 m depth, which could cause a significant reduction in permeability of the reservoir due to coal deformation.

Difference Between Volumetric And Gravimetric Coal Feeder

Difference Between Volumetric And Gravimetric Coal Feeder. The key difference between gravimetric and volumetric feeder is that we measure the rate of a gravimetric feeder in the unit of volume per unit time whereas we measure the rate of a volumetric feeder in the unit of weight per unit time Feeders are useful to handle bulk solids.
