What is Black Powder?<\/strong><\/h2>\n

Black powder consists of iron compounds including magnetite (mill scale), iron sulphide, sand, clay, salt, weld slag and even iron.\u00a0 The powder is created during gas production, or in wet gas pipelines where hydrogen sulphide, carbon dioxide or oxygen are present in the gas, or by bacterial corrosion of the steel.\u00a0 These deposits are normally black in color and can be in a dry, dust form or wet when combined with hydrocarbon liquids, compressor oils, etc. The powder is then distributed through the pipeline with the gas flow, but is deposited when the velocity is not high enough to keep it moving (Dr John Smart \u2013 \u201cMovement of Black Powder in Pipelines\u201d<\/a>). As sediment is deposited, the flow in the pipeline is disrupted and reduced, thereby allowing more sediment to accumulate. System through puts are affected and energy costs increased to maintain design flow rates. Blockage can occur especially during cleaning and damage caused to plant such as compressors.<\/p>\n<\/div>
