Separation of Freons and water
Separation of Freons and water. Filatkin, V. N.; Plotnikov, V. T.; Alishev, A. G. (USSR). Kholod. Mash. Ustroistva, 77-80. Edited by: Kurylev, E. S. Leningr. Tekhnol. Inst. Kholod. Prom-sti.: Leningrad, USSR. (Russian) 1976. CODEN: 37LIAZ. DOCUMENT TYPE: Conference CA Section: 61 (Water) Section cross-reference(s): 48 Freeze desalination plants, in which seawater is cooled by direct contact with the coolant, commonly use a vacuum deaerator to remove traces of coolant from the product water. This procedure may result in an appreciable loss of coolant and energy to recompress the vapor from the deaerator. To reduce the coolant loss to acceptable limits, the deaerator pressure should be <0.06 bar. Operation of the deaerator under conditions approaching adiabatic evapn. is economically advantageous. As regard to energy losses, Freon 318 [115-25-3] and Freon 114 [76-14-2] compare favorably with C4H10, but Freon 115 [76-15-3] is inferior.

DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) Poly(tetrafluoroethylene) (I) [9002-84-0] dispersions having improved av. particle size, uniformity of particle shape, and particle size distribution which can be concd. by simple procedures to form aq. dispersions contg. >75% polymer are manufd. by polymg. tetrafluoroethylene (II) in aq. dispersions contg. conventional peroxide initiators, 6% octafluorocyclobutane (III) [115-25-3] and 4% perfluorinated carboxylic acid salt dispersant. Thus, III 200, H2O 2000, ammonium perfluorocaprylate [3825-26-1] 4, and K2S2O8 13.4 g was heated to 35.degree.. II was added to maintain a pressure of 150 psig and polymd. to give a stable latex contg. 28% solids. The latex particles were spherical and had av. particle diam. 0.48 .mu. with particles ranging from 0.36 to 0.61.mu.. The distribution function was 0.19 and the mol. wt. of the polymers was 5.6 x 106. The latex was mixed with Triton X-100, the pH was adjusted to 5.0 by NH4OH, ammonium alginate was added, and the mixt. was let stand overnight. The concd. latex phase sepd. by decantation contained 79% I.
