Definition Life cycle assessment (LCA), also called life cycle analysis, is a systematic method for evaluating the potential environmental impacts associated with a product, process, or service throughout its life cycle. The assessment may cover raw material extraction, production, transportation,…
Definition A hydrocyclone, also called a hydraulic cyclone, is a separation device that uses a swirling liquid flow to separate suspended solids or immiscible liquid phases according to differences in density and migration behavior within a centrifugal field. Unlike mechanically…
Definition A centrifugal separator is equipment that uses a rapidly rotating flow field or rotating bowl to separate heterogeneous mixtures containing phases with different densities. It is commonly applied to solid-liquid mixtures and immiscible liquid-liquid systems where gravity separation is…
Definition Phase separation is the process by which a homogeneous mixture separates into two or more physically distinct phases because the components are no longer stable as a single phase under the prevailing conditions. The resulting phases may be liquid-liquid,…
Definition Degassing, also called degasification, is a separation process used to remove dissolved gases, entrained air, or gas bubbles from liquids and process streams. In chemical processing, the term most commonly refers to the removal of non-condensable gases dissolved in…
Definition Stripping is a mass transfer process used to remove volatile components from a liquid by contacting the liquid with a gas or vapor. Steam, air, nitrogen, or another suitable stripping medium may be selected according to the properties of…
