ACTIVITIES
3. MODIFICATIONS
Major modifications made to the 17 Effect Plant during the reporting period for
process and materials testing follow. An updated process and instrumenta-
tion diagram is attached in Part 2 of the appendix.
A. Flash Tanks
In order to evaluate modular performance properly, a knowledge of
condensate level is necessary. Level sight glasses were installed
on flash tanks 14, 15, and 16 in July, 1968. The module came
equipped with glasses on flash tanks 13 and 11 only.
During runs 14 and 15, the carbon steel shells of external flash
tanks 10, 11 and 12 all perforated at the external support ring;
they were replaced. Failure was attributed to external, general
surface corrosion. Data on the new tanks are:Installation
