Modernizing conventional process

Modernizing conventional process, for example, to replace conventional distillation with extraction distillation, or use reaction distillation to integrate reaction and separation processes, will lead to such advantages: lower energy consumption, decrease operation cost, reduce pollution and etc. In the meanwhile, with the springing up of new product and process, matched process should be updated accordingly, such as solvent recovery, tail gas recovery, etc. Furthermore, due to higher requirement to environment protection than before, the wastes from plant which are allowed for discharging in previous time have to be recycled now. All the above problems promote consumer to find new process solutions.

Zehua has comprehensive knowledge includes but not limited to solvent extraction, extraction distillation, reaction distillation, azeotropic distillation, which could provide new process design for clients.

Typical Processes:

  • Aromatics extraction distillation (C6-C8)

  • Azeotropic distillation (acetic acid dehydration)

  • Extraction distillation (De-C5)

  • Integrated process (acetic acid)

  • Solvent extraction

  • Recovery process (acetic acid)

  • Reaction distillation (esterification)

  • Azeotropic distillation (ethyl acetate)

  • Tail gas purification

  • Solvent recovery
