Addition of 3 brackets on the line before the liquid nitrogen into the liquid nitrogen metering tank. Add fixed racks on the main cold, liquid oxygen metering tank oxygen export line converge into out of the main cold before the oxygen main, add brackets on the lower tower. From the bottom to the top of the second elbow down about 1.5m of the liquid air out of the lower tower pipeline to add fixed brackets. Before the dirty nitrogen into the subcooler, the original bracket is changed to a frame type movable pipe. The bottom of the crude argon tower liquid argon back to the upper tower pipeline on the blow-off tube from the root is no longer used. Liquid air into the upper tower before the fixed bracket; liquid nitrogen into the upper tower before the original bracket removed, do fixed bracket. Rough argon Chuan tower condenser liquid air steam into the upper tower line on the valve removed in its place to do fixed bracket. Expansion air into the upper tower, in close proximity to the upper tower straight pipe section of the top elbow down about 800mm to increase the fixed bracket. After the expansion air enters the upper tower, add brackets to the base of the main cooling box after the pipework has passed through the bulkhead. Additional brackets are added 1.5m down from the main cold liquid oxygen discharge blow-off main pipe. Main cold non-condensable gas blow-off pipe with additional fixing brackets and guide brackets.
Using an advanced digital dual-mode system, DEAR has created a truly digital production line. Through the 3D digital modelling of the production line, all small air separation units, large air separation units and liquid air separation plants can be simulated for production, data implemented for display and planned for perfect optimisation. It truly allows the customer to keep track of the data order status in real time.
