Core equipment of air separation plant—fractional column

Fractional column is the general name for the whole set of equipment consisting of cold box, main heat exchanger, evaporator-condenser, sub-cooler, rectification column, turbine, cryogenic valves, pipes and meter tubes. Cooling, liquefaction and separation of process air, expansion and warm-up of oxygen-rich air and warm-up of product gas are all carried out inside the fractionation column. The rectification column is made of aluminum, and is the highest equipment inside the cold box. It is the class I pressure vessel. The rectification column is installed with packing. Air separation of is achieved in the rectification column. Through all kinds of I/O nozzles, the rectification column is connected with heat exchanger, vaporizer-condenser etc unit efficiently, to realize the liquefaction, separation of air, sub-cooling of liquid air and gas warm-up.

Advanced air pre-cooling system

For the plant, which nitrogen capacity is not larger than oxygen capacity, waste nitrogen chilling type pre-cooling system is preferred. Such system is to cool compressed air with dry waste nitrogen. Towers in pre-cooling system are filled with structured packing, which features on little resistance, high efficiency, low power consumption (only with 1 unit of water pump), large feeding capacity and etc. Such pre-cooling system can also wash the process air. We are the first Chinese supplier who bring such waste nitrogen chilling pre-cooling system into configuration of small air separation plant.

Technical advantages of plants whose capacity are smaller than 350Nm3/hO2

Technical advantages of complete low pressure plant KDON-80/40; This plant is the smallest ASU with complete low pressureplant in China, which was initially developed by XLA in 1997. This plant is a revolutionary promotion for process of small plants. It took place of traditional KZON-50/100 as soon as its successful commissioning. Specific power consumption of KDON-80/40 is even 50% lower than that of KZON-50/100. Titled as “New and High tech product of Jiangsu Province”in 2003; Designed and manufactured with several know-how technologies; Simple operation and maintenance, cost-effective.   Technical advantages of complete low pressure plant KDON-170/100; This plant was developed in 2002, working on same process with KDON-80/40. It took place of traditional KZON-50/100. Specific power consumption of KDON-170/100 is 50% lower

Hydrogen-free rectified argon system available on the plants with capacity above 1000Nm3/h O2

The first set of ASU plant with hydrogen-free rectified argon process of our company is KDONAr-2500/2300/70Y, which was successfully commissioned on 2004. Height of cold box is 37 meters. The first set of liquid plant with hydrogen-free rectified argon process is KZOAr-1100Y/35Y, which was successfully commissioned in 2006 with stable running till now. Height of cold box is 35 meters. Up till now, it is the smallest hydrogen-free rectified argon plant in China.

EPC Project of Nitrogen Plant for Messer Group

Xinglu won the nitrogen air separation EPC project of Haerbin Nestle program for Messer group in 2012. The program is located in Shuangcheng City in Haerbin where its average temperature in Winter is lower than -30degC. During project design and equipment manufacturing, more factors should be thought about, such as influence of low ambient temperature to metal material, cold air influence on compressor mechanical performance, sandstorm environment to feed air filter of compressor and high extraction based in required compressor by customer. Organized by cryogenic separation technology research center of our company, the above problems are solved through analysis together with design institution and customer. The plant has been accepted successfully. In the beginning of 2013, when it is the most frozen season in Haerbin, the plant run steadily after commissioning, each parameter is better than

Internal compression air separation plant

Internal compression air separation plant process is to produce gas products with medium/high pressure directly from ASU without oxygen, nitrogen or argon compressors. Internal compressor plant is also customer-oriented. Compared with external compression process, the internal compression process features on that the product oxygen pressure is achieved in cold box with LOX pump. At present, the internal compression process is widely used in ASU plants which require big amount of liquid product and higher delivery pressure of gas product. Without product compressors, so no high temperature gas product; less mechanical failures; safe operation; When liquid product amount (total quantity of LOX, LIN and LAr) is higher than 8-10% of total product quantity, internal compression plant has lower power consumption than external compression plant. When
