Coinjected
Coinjected refers to a process where two or more substances are introduced simultaneously into the same stream or system. This method is commonly employed in various industrial and scientific applications to achieve specific reactions, enhance efficiency, or modify the properties of a material. For instance, in chemical engineering, coinjection might be used to mix reactants to promote a desired chemical transformation or to introduce a catalyst along with the substrate. In the petroleum industry, coinjection is a technique used in enhanced oil recovery, where two fluids, such as water and a gas or a polymer solution, are injected into a reservoir to improve the extraction of crude oil. This can help to sweep oil towards production wells or reduce the mobility of the oil, making it easier to recover. In some manufacturing processes, coinjection might involve introducing different additives into a polymer melt to achieve specific material characteristics like improved strength or flame retardancy. The precise control over the timing and ratio of the injected substances is crucial for the success of coinjection processes, often requiring sophisticated pumping and metering equipment. The term emphasizes the simultaneous nature of the injection, distinguishing it from sequential or separate introductions.
