Definition Random packing, also known as dumped packing, refers to packing materials that are randomly loaded into a packed tower rather than being installed in a structured arrangement. These packings create a large gas-liquid contact area inside the column, allowing…
Definition Packing, also known as a filler, filling agent, or extender, refers to a material added to another substance to occupy space, modify properties, or improve processing performance. In materials science and industrial manufacturing, fillers are widely used to enhance…
In our communication with clients, we often hear questions like these: • If a pilot test fails, who investigates the problem, and who is accountable? • After the contract is signed, how will the project move forward? Who will coordinate…
Definition Distillation is a separation and purification process used to separate the components of a liquid mixture based on differences in volatility or boiling point. The process involves heating a liquid mixture until one or more components vaporize, followed by…
Definition Structured packing is a type of tower packing used in mass transfer equipment such as distillation columns, absorption towers, extraction towers, and reactive distillation systems. Unlike random packing, structured packing consists of regularly arranged corrugated sheets made from metal…
Definition Extractive distillation is a specialized separation technology that improves the separation of liquid mixtures by introducing a high-boiling solvent, often referred to as an entrainer. The added solvent changes the relative volatility of the components in the feed mixture,…
Definition Fractional distillation, also known as rectification, is a separation process in which repeated vaporization and condensation occur within the same equipment to separate the components of a liquid mixture. It is a specialized form of distillation designed for mixtures…
Definition Reactive distillation, also known as catalytic distillation, is a process technology that integrates chemical reaction and distillation separation within a single unit. In practical applications, heterogeneous catalytic reactions and product separation occur simultaneously inside a reactive distillation column. Unlike…
Definition Crystallization is a separation process that utilizes differences in the solubility of one or more dissolved solids in a solvent to achieve purification or separation. When the solubility of a target substance decreases under specific conditions, such as temperature…
Definition A crystallizer is a piece of process equipment used to perform crystallization operations. Its primary function is to promote the formation and separation of solid crystals from a solution by creating a controlled state of supersaturation. In industrial practice,…
