Ethanol Refining Tower
Ethanol rectification towers are suitable for alcohol recovery in industries such as food, light industry, and chemical engineering to reduce production costs and enhance economic benefits. This unit can distill dilute alcohol, and for products requiring a high concentration of finished alcohol, increasing the reflux ratio is possible, although this may reduce the yield. The residual liquid's alcohol content is also reduced, making it an ideal equipment for alcohol recovery. The device is equipped with two feed ports; low-concentration feed is introduced through the lower feed port, while high-concentration feed is introduced through the upper feed port. The lower the feed concentration, the greater the reflux ratio; conversely, the higher the feed concentration, the smaller the reflux ratio.
Preparation for Ethanol Distillation Tower Startup
(1) The product has undergone hydrostatic testing and trial operation before shipment, and the specifications meet the drawing requirements.
(2) Test the waters.
(3) Carefully inspect all equipment, valves, and automatic control instruments in the entire distillation process, according to the flowchart, ensuring they meet requirements. Check for reversed check valves and correct any issues promptly.
(4) Operate each pump individually to ensure they are fully lubricated with oil, and promptly repair any issues found.
(5) Clear the site, dismantle installation and decoration scaffolding, remove debris, and ensure the operation area is open and tidy.
(6) Calibration and marking of instruments and meters.
(7) Notify production scheduling to supply water, electricity, steam, and compressed air on schedule as per the plan.
(8) Inspect the valves of the process piping, drain valves, and vent valves to ensure they are in the correct position.
(9) Inspect steam valves and cooling water gauges for proper operation, ensure the pipelines are clear and unobstructed, and check for any leaks.
(10) Verify that each valve is in the correct open/close position, and only proceed with starting the machine after a double-check confirms accuracy.
