structured packing


Our structured packings have emanated as the singular and total solution to effectively and economically solve the separation problems relating to heat, energy and space. We have replaced conventional packings in a number of applications with our specially designed structured packing, sheet structured packing radically altering the morphology of distillation, extraction and absorption systems. The structured packings are specially designed internals, made out of select metal sheet or wire gauze.

We have the in-house expertise to design and manufacture, columns for distillation, absorption, extraction and also the structured packings, which constitute their vital internals. With refinements in the geometric structure of the packings, we have been able to ensure higher and more efficient mass transfer.

We have a number of models in structured packings, each one tried and proven, developed and improved consistently by our technical team. Our structured packings are comparable to the finest, both in the domestic as well as the international market. The technical advancements and continuing research has resulted in the development of better designed packings at lower cost - the benefit of which is reflected in the economic pricing of our quality packings.

ADVANTAGES
In comparison to Random Packings and Trays of Various types, Re-Hitek Packings offer following advantages

  • Higher loading/throughput of columns, especially for larger diameter columns.
  • Lower pressure drop, especially for vacuum operations - resulting in lower operating temperatures (important for heat sensitive materials).
  • Low packing volume - especially for high number of stage requirement as in isomers separation.
  • Smaller hold-up.
  • Unchanged performance even at lower loadings.
