Ethanol Distillation Tower


Ethanol rectification towers are suitable for alcohol recovery in industries such as food, light industry, and chemical engineering, helping to reduce production costs and enhance economic benefits. This unit can distill dilute alcohol, and for products with high concentration requirements, increasing the reflux ratio is possible, although this may decrease the yield. The effluent contains a reduced alcohol concentration, making it an ideal equipment for alcohol recovery. The device is equipped with two feed ports; low-concentration feed enters from the bottom port, while high-concentration feed enters from the top port. The lower the feed concentration, the higher the reflux ratio; conversely, the higher the feed concentration, the lower the reflux ratio.


       Preparation before starting the ethanol distillation tower

(1) The product has undergone hydrostatic testing and trial operation before shipment, meeting the specifications as per the drawings.

(2) Test the waters.

(3) Carefully inspect all equipment, valves, and automatic control instruments in the entire distillation process according to the flowchart, ensure that check valves are not installed backwards, and correct any issues promptly.

(4) Operate the equipment individually to fill all pumps with oil, and promptly repair any issues found.

(5) Clear the site, dismantle installation and renovation scaffolding, remove debris, and ensure the operation area is clear and tidy.

(6) Calibration and marking of instruments and gauges.

(7) Notify production scheduling to supply water, electricity, steam, and compressed air on schedule as per the plan.

(8) Verify that the valves of the process pipeline, the drain valve, and the vent valve are in their normal positions.

(9) Inspect steam valves and cooling water gauges for proper operation, ensure pipelines are unobstructed, and check for any leaks.

(10) Verify that all valve doors are in the correct open/close positions, and only proceed with starting the machine after a double-check confirms correctness.
