Reported in the previous period, we introduced water-saving characteristics of liquid ammonia fertilizer direct fertilization and experimental demonstration of many areas have done a lot of studies have shown that ammonia applicable to all types of soil and crops, and further demonstrates the Advantages of liquid ammonia fertilizer directly, not only can save a lot of energy, improve fertilizer efficiency, while reducing pollution, increase food yields and reduce costs. And the development in the Xinjiang region is relatively rapid, high resource utilization. However, ammonia in order to obtain a large-scale promotion, crucial pipeline.

Ammonia help strengthen pipeline construction promotion

Most of the world's ammonia production using natural gas as raw material. Large ammonia plant in the southern United States natural gas and natural gas resources to import concentrated, liquid ammonia products by pipeline to the agricultural production areas. Built three major US long-distance pipeline network, including two from south to north and from west to east of a line, the line name is called Bay center line and the Mid-America Pipeline. (See table).

US pipeline transportation of liquid ammonia is very common, and railways, road transport freight comparative advantage of having the lowest, but the larger pipeline construction investment. Although the highest road trucking costs, but there is greater flexibility, conditional waterway transport, to large barges transported to the transfer station it is more economical. In the 1135-1185 km distance transportation barge transportation fee $ 8.38 / ton, pipeline transportation fee $ 10.41 / ton; 1700-1723 km distance transportation barge transportation fee $ 7.44 / ton, pipeline transportation fee $ 15.76 / ton.

Should further increase the ammonia test demonstration

In China, Hebei Province, was built the first liquid ammonia transfer line cities. Ammonia transfer line from Hebei Lulong fertilizer plants, fertilizer plants by Changli County, Qinhuangdao Funing County fertilizer plant to reach Arab Fertilizer Company, a total length of 82.5 km, with an average annual transportation capacity of 107,000 tons, the maximum capacity of 128,000 tons, The total investment of 18 million yuan. This transfer line is designed by the Hebei Province Petrochemical Design Institute, China National Petroleum Corporation pipeline construction bureau, the whole project took two years and three months, put into operation in 1990, 89,108 and 133 mm diameter. Ze Shan County in Xinjiang's Aksu City, East County Library, Korla and other places to build a large ammonia plant, had planned to carry liquid ammonia pipeline in the region, replacing tankers; the current strengthening of drip irrigation technology and management, long-term liquefied ammonia direct fertilization coexist, the former main project is the integration of water and fertilizer.

Ammonia can be applied to promote energy conservation, improve fertilizer efficiency, direct liquid ammonia fertilizer now has a large area in Beijing, Zhejiang, Shandong, Hebei, Guangdong, Xinjiang and other places, you need to focus on the development of the pipeline is liquid ammonia construction and ensure the supply of resources, only ammonia to ensure continuous supply, reduce transportation costs and costs to be able to promote the use of faster. Recommends that government departments to increase efforts to support the development of liquid ammonia, the introduction of economic policies to protect liquid ammonia, the relevant departments of supervision and inspection, strict quality control, open up the situation for the pioneering development of liquid ammonia. In addition, you can continue to experiment demonstration area in soil conditions are right, it will be an area set to ammonia fertilizer pilot. Enterprises can also give priority to the grower and farmer and other large farmers in promotion, if necessary, a free trial, large farms to see the effect of liquid ammonia fertilizer so that they can bring back the awareness of ordinary farmers, so that liquid ammonia The promotion will be able to proceed smoothly.
