Engineering Risks & FAQ - **Caution**: - **Caution**: - **Caution**: ### Q: What is the typical application of this modular distillation system? **A**: It is used for continuous separation of liquid mixtures in chemical manufacturing, such as solvent recovery, monomer purification, or intermediate product isolation, where high-purity separation is required. ### Q: What materials are available for construction? **A**: Materials on file include stainless steel 316L, borosilicate glass, PTFE gaskets, and ceramic packing. Material compatibility must be verified for the specific chemical process. ### Q: What are the key parameters to consider for selection? **A**: Key parameters include column diameter (300–6000 mm), operating pressure (1.0–1.6 bar), temperature range (-40 to 350 °C), number of theoretical stages (10–100), heat duty (0.5–10 MW), flow rate (1–500 m³/h), and separation efficiency (95–99.9%). ### Q: How does the modular design affect installation? **A**: The pre-fabricated, skid-mounted design reduces on-site installation time and costs compared to field-erected columns, as it is delivered as a complete unit with integrated controls and utility connections. ## 6.
