The most common method of separating a liquid from an insoluble solid is the filtration. Take, for example, the mixture of sand and water. Filtration is used here to remove solid particles from the liquid. Various filtering agents are …
Separation of CH4/N2 of Low Concentrations From Coal . The PSA separation method has become the mainstream technology for the purification of coal bed gas at small and medium scales, due to its advantages of low energy consumption, less investment equipment and high degree of automation (Arya et al., 2014; Yin et al., 2015).
The experimental method of coal direct oxidation (DO) desulfurization was as follows: oxidants (H 2 O 2, KHSO 5, Fe [ Fe ( CN) 6] 3) were configured with deionized water to form an oxidant solution, in which the pH value of the solution was adjusted by HCl or NaOH. CS was added into the oxidant solution and stirred at a speed of 500 rpm.
