Air Liquide Air Separation Unit clogged cold Diagnosis and Treatment
Emptied away. Remove the stainless steel mesh, found that some Received Date :2003-09-21 Author: Zhi-Gang Yin (1970 a), male, technicians, college graduates, now working at Harbin Gasification Plant oxygen plant. '52 'CryogenicTechnologyNo32004 cryogenic technology 3 Zhi-Gang Yin, 2004: Air Liquide Air Separation Judgement and clogging cooling technologies are blown to deal with security marks. Liquid air cooling device cut both ends of the head channel and found that glass cotton stuck in an empty part of the liquid cooling device channel. Judge proved to be correct. 3 approach we will start with 0.6MPa of instrument air cooling device in the outlet of the cleaning liquid air, blowing glass cotton can not afford the fine steel wire with a hook to pull out, the liquid air stainless steel mesh and glass adsorber cotton replaced by a new and installed. ASU started on the tower before the purge,[link widoczny dla zalogowanych], liquid air pipe cleaning. Also proposed measures for controlling air inhaled environment on emissions for recycling. Operating on the 14d Air Liquide absorber reduced the switching cycle 12d, was also used silica gel to clean off the pre-cooling liquid air liquid air to adsorber. Air Liquide is the outlet valve before the adsorption leads to a 4 valve liquid with blowing the same caliber of the pipeline, inserted into another liquid air absorption inlet valve,[link widoczny dla zalogowanych], a valve at both ends of the increase, the middle of a small drain valve. Air Liquide pipeline absorber added as shown in Figure l (dotted line was added after the pipeline and valves). After the transformation, just open the valve ※ ※ pipeline plus a small handful of liquid indiscriminately (added) Figure 1 Air Liquide Pipeline diagram added absorber can be pre-cooled to liquid air door absorber, do not open large valves, thus reducing large failure rate of the valve, but also greatly reducing the solution space and the rapid evaporation of liquid air gases on the impact of the lower stainless steel mesh. To take these measures, I plant air separation plant has been operating normally, Air Liquide adsorber blasting, liquid air cooler blocked off the accident did not occur again. Build a world-class Shanghai Research Center of Coal Oil Expected in July 2004, the processing 6 tons of coal liquefaction process development unit, will be in Shanghai, Wu Jing Industrial Park put to trial. The immediate goal of the center, through the efforts of 3 to 5 years to build a world-class coal liquefaction research institutions. China's oil resources are limited. Solve the problem of shortage of oil resources, on the one hand by ※ imported from abroad, the other way is the implementation of coal-oil. The coal into oil, will bring a revolution in the domestic energy industry. In accordance with the existing direct China's rich coal resources, to maintain reserves of over 1 trillion tons. Experts believe that, start coal liquefaction industry,[link widoczny dla zalogowanych], will enable some of the rich coal resources into oil products, not only to meet the needs of oil consumption, to ensure national energy security is also positive.

The set of all-low-pressure air separation plant, molecular sieve purification, pressurized turbo-expander refrigeration, full distillation argon, oxygen outside the compression process,[link widoczny dla zalogowanych], with the process advanced, the technology is mature, reliable, easy operation, low power consumption and other security features. Performance indicators such as the table below.
