Abstract: The pressure control of the reformed product separation tank of a company’s continuous reforming unit of adopts the control system of the American Compressor Controls Corporation (CCC).In the actual production and operation, the main throttle valve of steam turbine of reforming turbocharger acts frequently, and the opening fluctuation is as high as ±20%, resulting in increased wear of sealing packing and leakage. Through the analysis of the factors affecting the valve opening, it is found that the main valve opening can be stabilized through stabilizing the reforming hydrogen production, stabilizing the temperature of each sub-tank of the compressor, stabilizing the compressor rear pressure, adjusting the speed control oil signal of the turbocharger, and adjusting the operating point of the turbocharger and so on. After the implementation of various measures, the fluctuation of the main valve opening of the steam turbine is reduced from ±20% to ±5%, and the hourly fluctuation range is ±0.5%. The packing of the main valve of the steam turbine do not leak again, which effectively guaranteed the long-term operation of reforming turbocharger.
