Abstract:

The development of the first-generation, second-generation and third-generation integrated heat tracing station technologies in petrochemical unit is introduced，and their advantages and disadvantages are summarized. The first-generation integrated heat tracing station technology has low investment, large floor area and easily corroded carbon steel pipeline. The second-generation technology has high integration, corrosion resistance, close to zero maintenance cost and high engineering cost. The third-generation technology has small floor area, low engineering cost, corrosion resistance and low maintenance cost. The status quo of integrated heat tracing station technology is analyzed, and its future development is forecasted.

Key words: petrochemical plant, integrated heat tracing station, technological development, three generations
