n the field of development of coal chemical industry in recent years, technology of synthesis gas conversion of continuous improvement, promote technology progress and energy efficiency, the overall low temperature shift process is widely used in chemical production. As a kind of new energy saving technology of all low temperature shift process, in the same conditions, has the advantages of low energy consumption, the characteristics of large production capacity etc.. In view of the characteristics of low temperature shift process, production system actively planning, careful organization, the use of the favorable opportunity of other production facilities maintenance, co-ordinate arrangements for a comprehensive transformation of the 4# converter system.

Rectification of the 4# transform technology is low, process the original completely change the full low temperature shift process. In order to ensure the implementation of the project smoothly, the company has established a special technical command group, on-site guidance work. According to the process of the existing equipment, technical staff through on-site observation of measurement, and the detailed calculation and analysis the technical transformation scheme of detailed, complete. Take the original of the furnace into one or two sections total low temperature, while the humidifier humidifier water instead of gas, the implementation of cold shock, at the same time to reconstruct the original saturation tower, the main heat exchange and water temperature sensors and other equipment, effectively improve the efficiency of mass and heat transfer. This transformation makes full use of the existing equipment, realize the time is short, the optimal solution, investment requirements. Implementation of the transformation of the smooth, showing great source of wisdom and strength.

In the field we deeply touched, winter winter at the moment seems to have " gentle " a lot. All personnel involved in the technical implementation of twenty-four hours by operation, of any problems in practical operation are in no way let go, always careful analysis, formulate measures, the one one solution, in order to ensure the system drive smoothly and achieve the expected results.

After the technical transformation, under normal conditions, in accordance with the theoretical calculation, 4# transform steam consumption will be reduced by more than 50%, only this one year can save the cost of 5000000 yuan. At the same time, the resistance of the system will be further reduced, for stable after workers continued production and reduce electricity consumption will play a positive role.
