PROGRESS

in

improv­

ing processes for converting saline water has been made but large scale conversion plants furnishing potable water at economic prices are not just around t h e corner. This was the con­ sensus of the international symposium on saline water conversion held in Washington, D . C. Scientists from 10 foreign countries joined with United States experts in the symposium spon­ sored jointly b y t h e National Academy of Sciences a n d interior Department's Office of Saline WaterOne of the principal purposes of the symposium was t o recommend to the Office of Saline W a t e r what directions its programs should take to reach its goal—finding ways t o convert saline water at acceptable costs. Said O S W director David S. Jenkins a s h e opened the symposium, "Interest and activity in process research a n d development was good during the first few years of the program, b u t t h e flow of sound new ideas to t h e federal program n o w shows some tapering off." According t o Jenkins, processes w i t h

good potential are limited to t h e s e five groups: • • • • •

Distillation. Solar distillation. Electrodialysis. Osmosis. Freezing.

Within these groups, OSW is putting emphasis on processes showing the most promise. • Cost Big Factor. What constitutes an economic conversion cost depends on the end use of t h e water. Accord­ ing to Jenkins, converted water for industrial use could cost a s much a s $ 3 per 1000 gallons. But for municipal use, t h e t o p figure is $0.35 per 100O gallons, and irrigation water can cost no more than $0.12 per 1000 gallons. H o w do costs of various processes stack up against these figures? T h e answer is confused. Reason: No b i g multimillion-gallon-a-day conversion plants are in operation; cost figures for large scale operation are projected from laboratory or small pilot plant data.

• A survey to determine t h e future water needs of all areas of the United States would be highly desirable. However, if cost of the proposed sur­ vey would mean cutting OSW funds, t h e survey should be postponed in­ definitely. • Work on saline water conversion processes should be aimed at industrial a n d municipal uses where acceptable costs are relatively high; the maximum acceptable cost of w a t e r for irrigation is too low to make this area attractive at present.

Here's the way the cost picture looks. For distillation, cost estimates r u n from a low of 30 cents to a high of $2 per 1000 gallons, Solar distillation costs range from $ 1 to more than $6 per 1000 gallons, while t h e electrodialysis process gives costs ranging from 30 cents to $1 p e r 10OO gallons. Esti­ mated costs for freezing processes are about $2 per 1000 gallons. First firm cost figures on water con­ verted b y electrodialysis should be available late next year. Now under construction, a 3-inillion-gallon-a-day electrodialysis plant will go into opera­ tion next year at Welkom, Orange Free State, to desalt gold mine water. Ο. Β. Volckman, South African Council for Scientific and Industrial Research, says he expects t h e big plant to produce potable water for 3 0 cents p e r 1000 gallons, and prospects a r e good for a 27-cent cost. • Program for O S W . T h e sym­ posium was divided into sections, each covering one of the major saline water conversion processes. A t the sympo­ sium's close, the chairman of each section gave Jenkins the recommenda­ tions of his group for Office of Saline Water's future program. All groups agreed o n these points:

• There should b e increased partici­ pation i n foreign projects and a more active exchange of information between O S W a n d foreign programs. Calling t h e symposium a great suc­ cess, Jenkins said O S W has no im­ mediate plans to hold a similar pro­ gram in t h e future. However, h e pointed out t h a t U N E S C O is planning a similar symposium to be held next year in Iran.

H e r e ' s good news for l a b o r a t o r i e s — especially those with limited space. Kewaunee's new Airflow Thinwall Fume Hoods provide 5 inches more working space in 4 inches less room spaceRigorous testing and actual laboratory use indicate that the new Thinwall Hoods are only slightly less efficient than Kewaunee Supreme Hoods, a n d have approximately 50% greater efficiency than most conventional Hoods. It has a variety of outstanding features, too. Eye-level remote control and service fixtures . . . automatic bypass . . . excep­ tionally attractive appearance. In every detail you'll find the Thinwall has been thoughtfully designed to fill a real need— and craftsman-built for years of efficient, economical use.

• Oïïn Mathieson has registered the $60 million worth of convertible debentures it plans to sell (C&EN, Sept. 30, p a g e 29) with SEC. Proceeds will b e used for expansion and for additional working capital. Olin Mathieson expects its capital outlays next year (other than for its aluminum program) will not vary much from the $47 million slated for 1957. Aluminum program requirements for this year and next are estimated at $47 million in addition to $65 million being obtained b y private sale of 4% promissory notes. Olin stockholders have approved comp a n y plans to increase its authorized shares of common stock from 15 to 20 million. • Victor Chemical will build its ninth manufacturing plant on a 35-acre site fronting on the Little Calumet River on Chicago's south side. Products will include a range of phosphate chemicals, will supplement production at Victor's Chicago Heights plant. The new site will be served b y the Chicago & Eastern Illinois Railroad, from which it v/as

bought. I t also has easy access to truck routes, t h e complete Illinois, Mississippi, Ohio, and Missouri waterways system, Great Lakes points, and the St. Lawrence Seaway. • Celanese's 15-rnillion-pound-a-year acrylate ester plant goes on stream at Pampa, Tex. T h e plant will use a process, developed by Celanese from basic B. F. Goodrich findings, that uses acetic acid and formaldehyde. • Philip Morris is taking a second step toward diversification. It plans to acquire Franklin Research Co. of Philadelphia, Pa., and P o l y m e r Industries, Stamford, Conn. Franklin produces emulsions, cleaners, polishes, and waxes for industrial use; Polymer makes adhesives for packaging and paper converting, also turns out specialty chemicals for t h e textile industry. • The B a d g e r - e n g i n e e r e d synthetic methanol purification expansion of Commercial Solvents at Sterlington, La., is now on stream. T h e unit uses Badger's n e w process to produce extra high purity methanol. Commercial Solvents makes synthetic methanol from natural gas and air, and refines the crude methanol by special distillation techniques so t h a t n o chemical treatment is involved in the process. • AtC cancels its plans to negotiate a contract with Foster Wheeler to develop and build a demonstration homogeneous reactor power plant to be operated by the Wolverine Electric Cooperative, Big Rapids, Mich. The commission is considering inviting bids from industry a t some future time for such a project. • General Electric gets the engineering design assignment from the AEC for a large-scale reactor to produce special nuclear materials. Deadline for the report on t h e design, including cost estimates and construction schedule, is April 1, 1958. • G e n e r a l Atomic, a division of General Dynamics, will build the first nuclear reactor designed for the custom production of radioisotopes, as well as for training a n d research, at its John Jay Hopkins Laboratory, San Diego, Calif. It is one of three reactor types that General Atomic is developing utilizing the new solid homogeneous reactor core \vhich, they say, is inherently safe.
