Efficiently Solving Foam Challenges in Decarbonization Processes: Chemi Tech's Specialized Defoamer Solution

Excessive foam generation is a common yet challenging issue in various industrial decarbonization processes. This foam not only reduces the effective volume of reactors or absorption towers, leading to a significant drop in processing efficiency, but can also cause liquid entrainment, resulting in material loss, reduced product purity, and even production interruptions and operational risks due to overflow. Conventional general-purpose defoamers often struggle to adapt to the specific chemical environment and temperature-pressure conditions of decarbonization systems, manifesting as slow defoaming speed, poor foam suppression persistence, or incompatibility with the system, which may conversely affect the stability of the main process.

Addressing these core pain points, Chemi Tech has dedicated itself to developing a series of specialized defoamers for decarbonization. Our solution is not merely about adding an auxiliary agent but is based on a deep understanding of the fluid chemistry in decarbonization processes. The products utilize specially modified polysiloxanes and compound technologies, possessing the ability to rapidly penetrate, spread, and break foam bubbles, while simultaneously forming a stable barrier at the gas-liquid interface to suppress foam regeneration at the source. Their design ensures excellent chemical inertness and defoaming/anti-foaming performance even under complex conditions such as alkaline or acidic absorbent liquids, elevated temperatures, and the presence of solid particles, without negatively impacting decarbonization efficiency or subsequent process steps.

The specific application steps are clear and straightforward: First, our technical team conducts a detailed diagnosis of the customer's specific decarbonization process, foaming medium composition, and operational parameters. Subsequently, through laboratory simulation and screening, we recommend the most suitable defoamer type and dosage. Typical injection points can be selected at key locations such as the lean liquid pump inlet, absorption tower circulation line, or rich liquid tank, with precise and continuous addition achieved via metering pumps. During the initial dosing phase, a concentration slightly above the recommended level is suggested to quickly establish an effective concentration within the system. Once foam is under control, the dosage can be reduced to a very low maintenance level, enabling cost-effective long-term operation.

We once assisted an energy company in addressing severe foam issues in the amine system of its carbon capture pilot plant. The unit frequently experienced column flooding when operating at higher loads, limiting its processing capacity. Following technical analysis by Chemi Tech, a customized high-temperature amine-specific defoamer was recommended. After injection according to the plan upstream of the lean liquid pump, the foam was effectively controlled within hours, column pressure drop returned to normal, and the system's processing capacity increased by approximately 18%. Moreover, the consumption of the defoamer was significantly lower than the product previously used by the client, achieving both operational stability and cost savings.

Choosing Chemi Tech means you acquire not just an efficient defoamer product, but a complete foam management solution tailored for decarbonization processes. We are committed to providing professional technology and services to clear foam obstacles from your decarbonization process, ensuring efficient, stable, and economical system operation.
