Show Kennecott Unveils New Acid Plant At Cost of $8 Million Kennecott Copper Corporation's Utah Copper Division has unveiled its No. 7 acid plant, which uses sulfur dioxide from smelter smoke for the production of sulfuric acid another step in Kennecotts program to reduce smelter emissions. The new plant under optimum conditions converts 163 tons of sulfur into 500 tons of sulfuric acid daily, and boosts to more than 1,300 tons the smelters daily acid production. Sulfuric acid produced from the smelters gases is used extensively in Intermountain industry as well as in Kennecotts own mine leaching and copper refining operations. The new $8 million facility was begun July 22, 1969 on a schedule designed to capture additional sulfuric dioxide before onset of this winters inversion period. The plant has been undergoing extensive performance tests since it first produced acid September 18 this year. Ore from Bingham Canyon is sulfide, meaning that it contains compounds of sulfur with metallic elements. During the smelting process, sulfur dioxide is emitted from the reverberatory furnaces and converters. Converter gases are conducted in huge flues through a gas purification plant to the acid plants where sulfur dioxide is transformed into sufur trioxide, then into sulfuric acid.. While the acid process is continuous, copper converters from which the gas comes are run on batch processes, accounting for variations in acid plant feed. The new contact acid plant therefore is designed to operate within wide fluctuations of sulfur feed from 2 to 8 sulfur dioxide content of input gases, with an average of The Utah smelters first acid plant was erected in 1937, designed to operate on roaster gas and produce 100 tons of sulfuric acid daily. Gases from smelter converter operations were first utilized for sulfuric acid production in 1944. Capacity of the second acid plant were continued, and as design and operating knowledge expanded, larger acid plants were installed. The smelter now has the capability to recapture all of the sulfur dioxide available from the converter flue system. The largest sulfuric acid user in the Intermountain area is the phosphate rock fertilizer industry. Other major uses include uranium processing, steel manufacture, water treatment, sugar and chemical production. A fleet of 50 tank cars is used for transporting acid to customers located near rail lines. Independent truck lines handle the needs of other customers. A tank farm of 25,000 tons capacity is maintained in southeastern Utah for acid reserves. Kennecotts project engineer for the new plant was J. L. THE SALT LAKE TIMES FRIDAY, DECEMBER 11, 1970 Page Twelve Lloyd Hopes for Early Approval Of Ammunition Exemption Bill Rep. Sherman P. Lloyd said Thursday he is hopeful that the House will approve next week to a bill he has repeal federal registration requirements on .22 caliber rim-fir- e ammunition. The legislation, approved by the House Ways and Means committee this week, would eliminate record keeping and reporting requirements on sales of .22 caliber ammunition set up by the 1968 Gun Control Act. Congress has already repealed of other rifle and shot gun ammunition from the law. These record keeping requirements have in no way contributed to crime control, and have constituted bureaucratic harrass-meto a great many sportsmen n Utah and other states, said reg-stratio- n nt Hep. Lloyd. Buyers must fill out a form with the purchase of every box of .22 caliber ammunition, and he sellers are required to keep voluminous records on sales, he said. The Utah Republican said .22 caliber weapons are among the most generally used by young leople who are being trained in he proper use and enjoyment of lirearms for sporting purposes. Its a wise thing to be satis-lie- d with your lot even if you a lot. lavent Hearing Set Jan. 6 On Amending Basin Milk Order Proposals to amend the Great Basin Federal Milk marketing order will be considered at a public hearing Jan. 6 in Salt Lake City, the United States Department of Agriculture has announced. The order covers parts of Utah, Nevada and Wyoming. USDAs Consumer and Marketing Service officials said the hearing will begin at 10 a.m. in the County Health Department Auditorium, 610 S. Second East. Proposed changes to be considered at the hearing were submitted by a dairy farmer cooperative representing a majority of the dairy farmers supplying milk to the area, and by the milk dealers doing business here. The principal proposals of the cooperative would: (1) change the minimum per centage of a plants monthly receipts that must be distributed on routes to be fully regulated by the order; and (2) replace Ogden and Pro-- ; vo with Salt Lake City as the point from which distances are measured in determing location adjustments. Handler proposals would (1) reduce the Class I (bottling milk price paid to farmers; and (2) change the basis for pricing the manufacturing milk. ma-neurver- Get the razor that getsihe Nubs.

Most of Visitors Fred Vandres, presiding minister for the Salt Lake City congregation of Jehovahs Witnesses said that an estimated 1800 persons gathered at the South high school auditorium to hear J. D. Wengert, district supervisor for Jehvoahs Witnesses, talk on the subject Who Will Conquer the World in the 1970s? He pointed out that there are those elements today which would like to conquer the world. He stated Today average people the world over are affected by the answer to our question. Carpenters, housewives and our school children are dying every day because of this issue and many more will yet lose their lives before it is finally settled once and for all. The international power struggle is over the question of which ideology and economic system will prevail and prove victorious over the other democracy or communism. Both of the major powers seem intent on protecting their sphere of influence and exand-in- g it wherever possible. So fierce has become the rivalry and competition between them that it is most difficult for any nation or people to remain uncommitted and strictly neutral in the struggle. Each days news recounts the latest frantic on both sides along with the latest incident or crisis that has developed. 4. If S.L. County Draws 1800 Attend Meet Of Witnesses in S.L. Easy to install.

Dont ing Attractions in Salt Lake county drew 40.3 per cent of nonresident all motor vehicle travelers to Utah last summer, and brought over $20 million into the countys economy, according to a report issued by the Utah Travel Council. The report showed an increase of $7.5 million in traveler expenditures for the county, over the summer months of 1969. Bill Backman, director of the Salt Lake County Convention and Visitors Bureau, said the increase was due, in part, to conventioneers who became vacationers after their convention ends. We are finding .that many people will spend a day or two touring the area and sightseeing, he said. He added that the gain also can be attributed to. joint efforts by the Convention Bureau and the Utah Travel Council in the travel shows, advertising, and literature. Lee Jorgensen, director of the Utah Travel Council, said that although Salt Lake County took the lions share of travel expenditures, nearly $30 million was spent in the other eight promotional regions. It seems that we have heavy concentration of spending in Salt Lake County due to its straand tegic location off plus its many attractions, but other regions fared well, in most cases better than last summer, he said. 1-- 80 5, |
