1987年美国硫的总产量为936万吨,比1989年下降5％。得克萨斯和路易斯安那州采用弗拉施法的各硫矿连续两年减产,而许多州从石油精炼厂和天然气厂回收的硫的产量则增加。迄今得克萨斯和路易斯安那州是美国产硫最多的两个州。弗拉施硫减产 1987年美国弗拉施硫的产量为320万吨,占硫总产量的34％,比1985和1986年的产量则下降36％和21％。彭佐伊 In 1987, the total sulfur production in the United States was 9.36 million tons, down 5% from 1989. Sulfur mines in Texas and Louisiana that adopt Fraser’s method have reduced their production for two consecutive years, while sulfur recovery from many oil refineries and natural gas plants has increased in many states. To date, Texas and Louisiana are the two states in the United States that produce the most sulfur. Flax Sulfur Production Reduction The production of sulfasalazine in the United States was 3.2 million tons in 1987, accounting for 34% of the total sulfur production, down 36% and 21% from 1985 and 1986 respectively.
