화학 공학에서 ‘연속 공정’이란 무엇인가?
정의: 연속 공정이란 원자재가 시스템으로 지속적으로 공급되고 제품이 지속적으로 배출되며, 공정 조건이 시간의 경과에 따라 비교적 안정된 상태로 유지되는 산업 운영 방식이다. 배치 공정과는 달리,…

What Is Process Design in Chemical Engineering?
Definition Process design refers to the systematic development and engineering of chemical processes based on technical requirements, patent information, and experimental data. It involves transforming laboratory-scale or patent-based technologies into fully engineered process systems suitable for industrial production. In chemical…
What Is Green Technology in Chemical Process Industry?
Definition Green technology refers to a set of engineering principles and industrial technologies aimed at reducing environmental impact while improving the efficiency of chemical processes. In chemical engineering, it is not a single technology, but a process design philosophy that…
Where Is the Real Bottleneck in PLA/PBAT Scale-Up?Three Core Equipment Solutions for Biodegradable Material Purification and Post-Processing
PLA/PBAT Commercialization: The Race to Lower Production Costs With the implementation of the EU Carbon Border Adjustment Mechanism (CBAM) and China’s dual-carbon strategy, conventional petrochemical production routes are facing increasing pressure. As PLA and PBAT move from laboratory development to…
What Is Condensation Polymerization?
Definition Condensation polymerization, also known as polycondensation, is a polymerization process in which two or more monomers containing two or more reactive functional groups combine to form polymer chains while simultaneously releasing small molecules such as water, hydrogen chloride, methanol,…
What Is Solution Polymerization?
Definition Solution polymerization is a polymer manufacturing process in which the monomer is dissolved in a suitable solvent before polymerization takes place. The reaction is initiated by heat or chemical initiators, with the solvent serving as the reaction medium to…
What Is Bulk Polymerization?
Definition Bulk polymerization, also known as mass polymerization, is a polymer production process in which the monomer polymerizes without the addition of solvents or dispersion media. Under the influence of heat, light, radiation, or chemical initiators, the monomer undergoes polymerization…
녹색 화학이란 무엇인가?
Definition Green chemistry, also known as environmentally benign chemistry, is the design of chemical products and processes that reduce or eliminate the use and generation of hazardous substances throughout the entire chemical lifecycle. Its objective is to maximize resource utilization…
현탁 중합이란 무엇인가?
Definition Suspension polymerization, also known as bead polymerization, is a polymer manufacturing process in which water-insoluble monomers are mechanically dispersed as droplets in a continuous medium, typically water, with the aid of dispersing agents. Polymerization occurs within these suspended droplets,…
에멀젼 중합이란 무엇인가?
Definition Emulsion polymerization is a polymer manufacturing process in which water-insoluble monomers are dispersed in water with the aid of surfactants (emulsifiers) and polymerized under mechanical agitation. Polymerization occurs within finely dispersed droplets or micelles, producing a stable polymer latex.…
