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.

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
