Mass Transfer Packing

From structured packing to random ceramic and plastic packing, our various mass transfer packing options provide increased efficiency and capacity and lower pressure drop.

Frequently Asked Questions

The primary purpose of mass transfer is to facilitate the movement or transfer of one or more substances from one phase to another phase. This typically refers to movement from a gas phase to a liquid phase or vice versa. This is a critical process in various industrial applications to separate, purify, or react to different components of a mixture.

Mass transfer is used extensively in industry for processes such as distillation, absorption, extraction and adsorption. These processes are employed in chemical manufacturing, petrochemical refining, pharmaceuticals, food production and numerous other sectors to separate, purify or react substances efficiently within mixtures or product creation.

There are two main types of packing materials used in mass transfer: structured packing and random packing. Structured packing consists of carefully designed and arranged geometric shapes meant to maximize available surface area and facilitate airflow, while random packing is comprised of irregularly shaped materials. Both types of packing provide surface area for mass transfer. The type of packing media is selected based on factors such as efficiency, pressure drop and the specific application requirements.

Random packing is comprised of irregularly shaped packing materials randomly placed within a column inside a regenerative thermal oxidizing (RTO) tower or distillation column. Stacked or structured packing, on the other hand, consists of carefully designed and arranged geometric shapes such as corrugated sheets or grids. Structured packing offers higher efficiency and lower pressure drop compared to random packing. It can be more complex and expensive to manufacture.

Packing a distillation column involves placing either random or structured packing material inside the column to create a large surface area for mass transfer. The packing is typically arranged or configured in a way that is meant to maximize contact between vapor and liquid phases.

When packing a distillation column, the placement of random or structured packing is not arbitrary, but it involves an engineered design or plan as part of a comprehensive system. The entire system often includes trays, column internals and other components designed to facilitate the separation of components contained within a mixture. Engineers employ mathematical modeling and simulations to design and optimize the packaging arrangement for each individual distillation column to achieve the desired separation objectives.
