Natural Gas.
Total production of natural gas in the United States in 1941 is estimated at about 3,800,000,000,000 cubic feet; after deducting losses (usually 18-20 per cent) and the amounts pumped back into the ground for storage or repressuring the field (5-10 per cent) the marketed production amounted to 2,770,000,000,000, an increase of 4 per cent over 1940. Of this total, various uses took the following percentages; light, fuel and power in the producing field, 23 per cent; domestic, 16 per cent; carbon black plants, 13 per cent; electric power and public utility plants, 7 per cent; petroleum refineries, 5 per cent; commercial uses, 5 per cent; other industrial uses, 30 per cent, including a small amount exported, mainly to Mexico. In addition to the 26 states in which it is produced, natural gas is piped to and sold in Alabama, Arizona, District of Columbia, Florida, Georgia, Iowa, Maryland, Minnesota, Nebraska, and North Dakota.
Natural Gasoline.
In 1941 more natural gas was treated for the recovery of gasoline than was consumed, a total of 2,900,000,000,000 cubic feet, resulting in the recovery of 2,697,000,000 gallons of natural gasoline.
Liquid Petroleum Gases.
By-product gases produced in petroleum refining are now liquefied and sold for domestic and industrial fuel. Output increased by nearly a half in 1940, to 313,000,000 gallons, and a similar increase may be expected in 1941.
Coke Oven Gas.
The only type of manufactured gas on which data are available is by-product coke oven gas. No information has been received on 1941, but the output in 1940 was 834,000,000,000 cubic feet, of which 36 per cent was used in firing the ovens, and 63 per cent was sold or used. Later output may be expected to follow approximately the trend of byproduct coke production, which increased 13 per cent in 1941 and 9 per cent in the first nine months of 1942.
