In December 16th, apparatus and equipment carbonization Workshop on 2# system transformation, removal and decarburization of three positions for technical maintenance.

2# transform system since its completion, using life is long, the decrease of reaction catalyst aging, active in the production, the heat of reaction is difficult to sustain the system heat balance, to rely on the furnace to maintain the temperature of reaction, and the resistance of the system increases. For chemical production is that this is not a normal situation, replacement transformation system catalyst can solve the problem must, therefore the company according to plan to transform 2# parking system and replace the catalyst. At the same time, the use of the parking opportunities to implement total low temperature shift on the transformation to the 2# conversion system, and the associated decarburization, variable off post overhaul of equipment, cleaning and inspection, to eliminate the hidden trouble of the system.

The main task of maintenance of the 2# system: one is the replacement of the catalyst converter system and the implementation of all low temperature shift transformation, the transformation of the need to increase the part of equipment, and the process is local changes. Two is the decarbonization system cleaning decarburization tower packing, part of the equipment shift, check and replacement of some equipment, pipeline and so on; three is the variable removal system cleaning refining tower packing, liquid distributor replacement and system tower, piping and valve inspection.

The maintenance time is short, the task is heavy and when the cold of winter, the maintenance personnel should not only perform maintenance tasks with high strength, but also overcome the cold weather. But in the repair process, repair personnel no one back, no one complained. In the overhaul of the tension, you always did not forget to work on the principle of safety first, quality first. Each point of operation in strict accordance with the safety operation procedure analysis, for the ticket. Safety supervisor is always adhere to the site in overhaul, urging everyone to strictly abide by the safety regulations. We have the spirit of responsible for ourselves, for enterprise and responsible attitude, in order to ensure the safety of the successful completion of the maintenance tasks.

In the maintenance process of a few days, the company leaders at all levels attach great importance, the company deputy general manager Fan Diancai, manager Fu Zong Zhang Haisheng often went to the scene to guide the maintenance work. Carbonization workshop director Guo Xuefa is stuck in the maintenance line, clothes can not see the original color, have stayed up bloodshot eyes.

The after maintenance, transformation system will achieve the energy saving effect. Low temperature shift furnace sections of inlet temperature are in 200 DEG, bed temperature decreased by 100 ~ 300 DEG C than the bed layer temperature is conducive to the transformation of the traditional, the reaction equilibrium. Because of the heat recovery rate is high, the steam consumption will also fall sharply. At the same time, but also greatly reduce the resistance of the system, effectively reduce the power consumption of the compressor. In addition, the system of decarburization and variable de process will also be optimized, improve the overall safety performance of the system, the production cost will be reduced obviously.
