Corrosion features hydrogen embrittlement

As the large scale commercial use of hydrogen fluoride is now well established, particularly in the petroleum industry, the techniques of the use of large size equipment is well known. Reports are available on various aspects of industrial use. A book has been published with particular reference to paraffin alkylation (Phillips Petroleum Company, 13). Corrosion, instrumentation, materials of construction, safety measures, etc., are included. The following journal articles also contain material of interest on large scale technique (Holmberg and Prange, 17, Frey, 18, Fehr, 19). There are certain features that need to be watched, such as corrosion, embrittlement, etc., but the above references deal with these subjects. Corrosion is not particularly serious in properly constructed equipment except where air enters.
