469Helium By Russell J. Foster1 Domestic sales of high purity helium (minimum 99.995% purity) in 1977 increased 37% to 789 million cubic feet.2 The Bureau of Mines sold 28% of the total, and private industry accounted for the remainder. Exports of high purity helium, all by private producers, declined 3% to 168 mil lion cubic feet. The Bureau of Mines f.o.b. plant price for high purity helium remained at $35 per thousand cubic feet, unchanged since 1961. High purity helium sold by private producers averaged approximately $22.50 per thousand cubic feet. DOMESTIC PRODUCTION Nine plants with the capacity to extract helium from natural gas were operational in 1977. Seven of the plants were owned by private industry and the other two were owned by the U.S. Government and operated by the Bureau of Mines. Five extraction plants were located in Kansas, two in Texas, and one each in New Mexico and Oklahoma. Total helium extracted from natural gas in 1977, by private and government plants, was 1.5 billion cubic feet, an increase of 12% over the amount produced in 1976. High purity helium extraction increased 27%, but the amount of crude helium extracted declined 9%. High purity helium produced for sale comprised 64% of the total helium extracted and crude helium constituted 36%. The Bureau of Mines accounted for 23% of the high purity and 22% of the crude helium extracted, and private industry the remainder. The Bureau of Mines awarded two contracts to CTI-Cryogenics, a division of Helix Technology Corp., for the construction, startup, and testing of a new helium purification facility capable of producing 600,000 cubic feet of pure helium per day from a 70% to 78% crude helium feed gas, and a new 500-liter-per-hour-capacity helium liquefaction facility at the Bureau's Exell, Tex., plant. Liquid helium production capacity of the Bureau will be increased to about 100 liters per hour with the addition of another helium liquefier at the Amarillo, Tex., shipping terminal in 1978. The unit was purchased from Kerr-McGee Corp.'s Navajo, Ariz., plant, which closed in 1976.
