Crude oil arrives at the refinery by ship and by pipeline from sources near and far. This diagram illustrates its travels in many forms to the variety of
units throughout the refinery for processing by separation, conversion or purification. Finally, what started as crude oil leaves the refinery by pipeline, barge, rail or truck as a variety of petroleum products for use locally or across the country
The various hydrocarbons produced are then chemically altered to make them more suitable for their intended purpose. For example, naphtha’s are "reformed" from paraffin’s and naphthenic into aromatics. These reactions often use catalysis, and so sulfur is removed from the hydrocarbons before they are reacted, as it would 'poison' the catalysts used. The chemical equilibria are also manipulated to ensure a maximum yield of the desired product. Step3 - Purification
The hydrogen sulfide gas which was extracted from the refinery gas in Step 1 is converted to sulfur, which is sold in liquid form to fertilizer manufacturers. The plant at Marsden Point also manufactures its own hydrogen and purifies its own effluent water. This water purification, along with gas 'scrubbing' to remove undesirable compounds from the gases to be discharged into the atmosphere, ensures that the refinery has minimal environmental impact [Once crude oil has been through separation and conversion, the resulting products are ready for purification, which is principally sulfur removal. This is done by Hydro treating, a process similar to Hydro cracking but without converting heavy molecules into lighter ones. In Hydro treating, unfinished products are contacted with hydrogen under heat and high pressure in the presence of a catalyst, resulting in
hydrogen sulfide and desulfurized product. The catalyst accelerates the rate at which the sulfur removal reaction occurs. In each case, sulfur removal is essential to meeting product quality specifications and environmental standards. Other units in the refinery remove sulfur, primarily in the form of hydrogen sulfide, through extraction, which is a second method of purification. Whether through hydro treatment or extraction, desulfurization produces hydrogen sulfide. Sulfur recovery converts hydrogen sulfide to elemental sulfur and water The residual sulfur is sold as a refinery by-product
