Witryna15 sty 2024 · Waxes. A mixture of these materials. The deposits also can contain resins, crude oil, fines, scales, and water. [1] Asphaltenes and waxes are a general category of solids and, thus, cover a wide range of materials. Understanding the fundamental characteristics that define the nature of asphaltenes and waxes is valuable in … Witryna12 kwi 2024 · A binary two-phase system has two degrees of freedom. At a given T and p, each phase must have a fixed composition. We can calculate the liquid composition by rearranging Eq. 13.2.4: xA = p − p ∗ B p ∗ A − p ∗ B The gas composition is then given by yA = pA p = xAp ∗ A p = ( p − p ∗ B p ∗ A − p ∗ B)p ∗ A p.
