Pipeline transport ethanol in Brazil, and there are several ethanol pipeline projects in Brazil and the United States. The main problems related to the transport of ethanol by pipeline are its corrosive nature and tendency to absorb water and impurities in pipelines, which are not problems with oil and natural gas. Insufficient volumes and cost-effectiveness are other considerations limiting construction of ethanol pipelines. Slurry pipelines are sometimes used to transport coal or ore from mines. The material to be transported is closely mixed with water before being introduced to the pipeline; at the far end, the material must be dried. One example
Trans Europa Naturgas Pipeline from Zeebrugge and in Mittelbrunn it is connected with the transport system of the MEGAL pipeline system which transports Russian natural gas from the German-Czech border to German regions and France. The length of the pipeline is and it runs in two lines. It has a capacity of 15.5 billion cubic meters per year which the operator intends to increase by 2 billion cubic meters per year. The diameter of pipeline varies from . The pipeline comprises four compressor stations. The pipeline is owned and operated by Trans Europa Naturgas Pipeline GmbH & Co. KG, a joint venture of Open
