| Summary: | The presence of unwanted chemicals in process lines and downstream equipment causes defects and
failures, which sometimes have significant impacts on systems and imposes extra costs for the production
process. In this study, one pair of four-stage make-up hydrogen compressors is investigated. These
reciprocating compressors which serve as a part of the hydrogen treating unit have failed approximately
simultaneously. The feed of these compressors is net hydrogen-rich gas. Both dry compressors have
shown similar problems in the first and second stages. The simultaneous rise in the cylinder temperature
and decrease in the flow has forced shut-down of the compressors for the next actions in the process.
Initial inspections have revealed some kind of deposits covered the cylinder and its components. The
valves, liquid tested and results have shown significant leakage of all the suction and discharge valves of
the cylinders. Moreover, the thickness of all piston rings have decreased up to 50 percent which is more
than allowable values. The compositions of deposits, tested by X-ray fluorescence (XRF) and X-ray
diffraction (XRD), result from the analysis shown that it contains 35,2 percent (mass fractions) of Chlorine
and 27,5 percent of Iron, and noticeable amount of Sulfur or Phosphor. XRD analysis has reported
that the Iron Chloride Hydrate is the main part of the fouling sample. In this paper, the impact of the
aforementioned chemicals on the compressor components are investigated, and some approaches are
proposed to absorb or inhibit these chemicals. |
