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
CLH Pipeline System CLH Pipeline System The CLH Pipeline System (CLH-PS), formerly the Government Pipelines and Storage System (GPSS), is a United Kingdom pipeline system run by Compañía Logística de Hidrocarburos (CLH). The network at one time consisted of over of pipeline and 46 other facilities. However, several of these facilities were closed before the GPSS was sold in 2015 and a number of the pipelines were mothballed and later 'abandoned'. Earlier the total number of facilities on the GPSS was much larger than 46. For example, in 1989 there were 40 Petroleum Storage Depots in operation plus large numbers of other facilities
