Proper chemicals allow safe and economical cleaning and emptying of a large crude line using compressed air, rendering the line hydrocarbon free with a LEL (lower explosion level) for the air inside the line of 0 %. Brenntag Oil & Gas Europe cleanded a 140-km, 24 inch OD crude transport line for the Total refinery in Vlissingen, Netherlands, using N-SPEC cleaning chemicals. Brenntag applied compressed air as a propelling agent to transport pigs through the pipeline, a technique rarely used in Europe due to the relatively high risks. Brenntag, however, succeeded in removing all hydrocarbons from the pipeline, bringing the LEL down to a unique 0 %.
