Definition Definition A plate heat exchanger (PHE) is a type of heat transfer equipment that uses a series of thin metal plates to transfer heat between two fluids. The plates are arranged to form alternating flow channels, allowing hot and…
Eliminating Thermal Runaway and Scale-Up Challenges How Tubular Reactors Are Reshaping Continuous Chemical Manufacturing In the fine chemical and specialty chemical industries, process engineers face two persistent challenges: thermal runaway and scale-up failure. The former threatens plant safety, while the…
Definition A heat exchanger is a device used to transfer thermal energy between two fluids in order to achieve heating, cooling, condensation, or vaporization. In most heat exchangers, the fluids are separated by a solid wall or heat-transfer surface, allowing…
Definition A tubular reactor, also known as a tube reactor, is a continuous-flow reactor characterized by its tubular shape and high length-to-diameter ratio. Depending on process requirements, a tubular reactor may consist of a single tube or multiple tubes arranged…
Definition A condenser is a type of heat exchanger primarily used to convert vapor into liquid through cooling. In chemical processing, refrigeration systems, and power generation, condensers remove heat from a vapor stream and promote phase change from the gaseous…
Definition A reboiler is a heating device used to vaporize liquid at the bottom of a distillation column. Also known as a bottom heater, it provides the thermal energy required to generate vapor, which rises through the column and supports…
Definition A gas distributor is a device used in gas-liquid or gas-solid separation and reaction equipment to distribute gas evenly across a process vessel. Its primary function is to ensure that gas enters the equipment at a uniform velocity and…
Definition A liquid distributor is a device used to distribute liquid evenly across the cross-sectional area of a packed bed or mass transfer column. Its primary purpose is to minimize the amplification effects caused by poor liquid distribution and to…
Definition Liquid-liquid extraction, also known as solvent extraction, is a separation process that utilizes differences in the solubility or distribution behavior of components between two liquid phases. The objective is to separate, recover, or concentrate a target substance from a…
Definition Extraction is a separation process used to isolate one or more components from a mixture by taking advantage of differences in their solubility in a selected solvent. In chemical engineering, extraction is commonly employed when conventional separation methods such…
