Carbon Adsorption Solvent Recovery, Separation, and Purification

Carbon adsorption systems, both regenerative and non-regenerative, capture vapor-phase emissions of volatile organic compound (VOC) solvents from solvent-based processes. The solvents are stopped from entering the atmosphere, thereby meeting environmental laws and regulations. In a regenerative carbon adsorption system, solvents are adsorbed on activated carbon. When the carbon is saturated with the solvent, it is regenerated with steam and the solvent is recovered when the steam is condensed.

Dürr solvent recovery systems offer two key benefits–environmental compliance and reduced operating costs. Water miscible solvents can be purified onsite with our distillation equipment, making it possible to reuse them, which also yields a dedicated ROI. As for non-water miscible solvents, they can be reused without further processing.

Stand-alone Dürr distillation systems purify waste water to make it suitable for disposal, thereby eliminating high disposal costs, or to separate solvents and purify them.

Thermal Processes

Dürr’s regenerative, recuperative, catalytic and direct-fired thermal oxidizers treat VOC emissions in gas or liquid phase to meet the most stringent environmental emission limits and regulations. Having offices worldwide, Dürr is also familiar with specific regional requirements and works very closely with Engineering Procurement and Construction (EPC) firms to design, develop and execute complete air-pollution abatement systems that include oxidizers, NOx control systems, scrubbers, wet electrostatic precipitators and vapor recovery systems. Our equipment is designed to provide maximum uptime, which is essential to chemical and pharmaceutical production facilities.

Our thermal oxidizer systems are used in applications where emissions are released from continuous or batch applications in various petrochemical and chemical processes, along with primary and secondary pharmaceutical manufacturing. Dürr also serves the chemical processing industry with the largest trained field service team strategically located worldwide.
