Anniston, Alabama Hr. J. R. Gould Anniston, Alabama Messrs: W. K. Bella / J I. Crouch' March 19, 1954 Biphenyl Reaction Pet V During * recent telephone conversetion with Mr. Paul Bcheuring of the Saereon-Bcheurlng Teak end Kenufecturing Company, Indianapolioi Indiana, 1 Mentioned to Hr. Bcheuring the trouble *e vere experiencing with biphenyl reaction pot failures and particularly our inability to veld in repair sections due to exceasive cracking. Hr. Bcheuring stated that in view of hie United knowledge of our biphenyl operations be could only Make e wild guess as to the cause of our trouble and that would be.excessive sulfur pickup. Re in formed ns that high nickel alloys were very sensitive to sulfur and that they had to discontinue the use of fuel oil in their heat tre ating process and go to sulfur scrubbed gas, due to the sulfur pick up in heat treating. . . The thought occurred to me that possibly the ioodward or Enjay bencol that has been'Used for the past few years could have had an excessively high sulfur content. One other thought is lead. As you probably know ve purchase Rt. Joseph Chemical Grade pig lead for use in the pots. However, as the old acid tanks were torn down all of the lead linings were reclaimed end used almost exclusively for quite a while. Thlx information is passed along for what it may be worth In your studies to determine the cause of the excessive pot failures and steps to be taken to elaminate these failures. 7/^ (2^9* tK Phillips 'tab i DEFENDANT'S DEPOSITION: I EXHIBIT IP '1%'OS- 969 ADA 002352 WATER PCB-SD0000046408
