	Naphtha - Wikipedia, the free encyclopedia
		Naphtha is a group of various volatile flammable liquid hydrocarbon mixtures used primarily as feedstocks in refineries for the reforming process and in the petrochemical industry for the production of olefins in steam crackers.
		Naphtha is obtained from [petroleum]] refineries as a portion of the distillation (also referred to as a cut).
		When used as feedstock in petrochemical steam crackers, the naphtha is heated in the presence of water vapour and the absence of oxygen or air until the hydrocarbon molecules fall apart.

		Since the olefins in the cracked naphtha are mainly in the low boiling fraction of these naphthas and the sulfur containing impurities tend to be concentrated in the high boiling fraction the most common solution has been prefractionation prior to hydrotreating.
		The organic sulfur compounds in the intermediate naphtha portion are brought into contact with hydrogen in the presence of a hydrodesulfization catalyst under conditions to convert the organic sulfur compounds to H2S which is removed with the intermediate naphtha portions as an intermediate naphtha overheads.
		The naphtha in the single pass fixed bed reaction may be in the liquid phase or gaseous phase depending on the temperature and pressure, with total pressure and hydrogen gas rate adjusted to attain hydrogen partial pressures in the 100-700 psia range.

		Naphtha is a general term used to describe special boiling point spirits having a boiling range of approximately 30 to 170 deg.
		Naphtha is widely used in fertilizer plants and petrochemical industries as a feed stock.
		This is because, in a fertilizer plant, Naphtha is reformed to carbon dioxide and hydrogen in presence of a catalyst which are used for the manufacture of Urea and Ammonia.

		Accordingly, a selective naphtha desulfurization process is needed for reducing the total sulfur level, particularly for high sulfur content naphtha feeds, with minimal mercaptan reversion, while retaining a high level of feed olefins.
		Any naphtha in the liquid state vaporizes during the hot, exothermic hydrodesulfurization reaction and the hydrodesulfurized naphtha effluent from each stage is all vapor, and this is what is meant by"vapor reaction stage".
		Even though the amount of sulfur removed from the naphtha in the first stage is greater than that removed in the second stage, the percent or extent of desulfurization is greater in the second stage than in the first.

	Alexander's Gas & Oil Connections - Rising Indian naphtha exports put downward pressure on regional market (Site not responding. Last check: 2007-11-05)
		The rush of Indian naphtha shipments is putting downward pressure on the regional market in the face of thin demand for the feedstock due to routine maintenance shutdowns at many petrochemical plants in North Asia, sources said.
		Naphtha prices are between $ 6-$ 7 per mm Btu, compared with about $ 4.50 per mm Btu for natural gas, inclusive of transportation tariffs on delivery to customers, industry sources said.
		Supplies of naphtha are also increasing as Indian refiners maximise run rates due to strong refining profit margins, trade sources said.

	SAFETY HAZARD IN NAPHTHA BASED GAS TURBINE POWER PLANTS
		Naphtha being highly volatile, inflammable and hazardous fuel, it has its own problem for using in power plants.
		Naphtha going to individual Gas Turbine is further pressurized, by Naphtha injection pumps provided in the Fuel Injection skid, to around 40-50 bar (depending upon Gas Turbine requirement).
		Fuel nozzle sprays naphtha with required air and atomizing air in the combustion chamber where naphtha is burnt.

		Therefore, the Naphtha feed is pretreated in the HDS Unit to remove the sulfur compounds normally found in straight run Naphtha.
		Naphtha feed, from the intermediate storage tank or surge drum pump, enters the unit at the suction of the Naphtha Feed Pumps.
		The purpose of the Naphtha Hydrotreater and the Hydrotreater catalyst is to remove elemental sulfur from the Naphtha.

	Documentation for Immediately Dangerous to Life or Health Concentrations (IDLHs)
		Because benzene is the most hazardous constituent of coal tar naphtha which is present in any appreciable amount, an IDLH of 7,500 ppm could be assumed.
		However, because the amount of benzene contained in naphtha is usually small, the lower explosive limit (LEL) of 10,000 ppm been used as the IDLH for this draft technical standard.
		However, the revised IDLH for coal tar naphtha is 1,000 ppm based strictly on safety considerations (i.e., being 10% of the lower explosive limits of the various constituents of coal tar naphtha which range from 1.0 to 1.3%).

		The plastics group noted that even the PNOC was forced to raise the target capacity of its own proposed naphtha cracker to 1.2 million MT from the original 600 MT on learning the results of the feasibility study.
		Uy also said that JG Summit’s proposed naphtha cracker is “over ambitious,” since the company would have to raise US$300 million for its construction, even as the company claims to be losing money.
		Since the naphtha cracker would be located in Batangas, the PPIA said JG Summit would have to pour in huge capital for the costly transport of high-pressure, low-temperature byproduct of its ethylene capacity.

	Alexander's Gas & Oil Connections - Excess of Indian naphtha looming
		India exported as much as 300,000 tons of naphtha for July, about double the volume sold on a monthly basis in 2003, and traders say exports could stay at a monthly 200,000 to 250,000 tons through the end of the year.
		That led to a reversal in the typical flow of naphtha, with at least one 80,000 ton naphtha cargo from the Saudi Arabia port of Rabigh being fixed for export to northwest Europe instead of Asia for second-half July delivery.
		The naphtha oversupply is likely to ease next year when new naphtha crackers come onstream in China and the Middle East, and this could to the resumption of normal arbitrage flows.

	Saudi Aramco World : Land of the Naphtha Fountain (Site not responding. Last check: 2007-11-05)
		To help him fund the construction of Baghdad, the new capital of the Muslim world, Caliph al-Mansur imposed a special "naphtha tax" on Baku; the middle of the eighth century thus marked the first appearance of a state tax on petroleum—a levy with which we are all still familiar today.
		The Persian king Yezdjerid I is said to have had a handkerchief cut from the skin of this mythical animal; he dazzled friends and foes alike by throwing it into the fire until it glowed red, and then retrieving it not only unburned but clean and without stains.
		What is interesting about this request is not so much the size of the shipment but that, first, the czar used the Arabic term "white naphtha," and second that he needed a refining master to accompany the petroleum—an indication that Russia had no refining masters of its own, and needed the technology of Muslim Caucasia.

		In both cases, Karnataka was the loser in terms of sales tax, while the so-called leaked or sold naphtha had clandestinely found its way to vehicle tanks as a petrol adulterant.
		The bottomline for the adulterator: naphtha is priced around Rs 12 per litre while petrol price is Rs 35, making adulteration a highly profitable business.
		However, the department found its hands tied since five of the six importers had declared their business premises outside Karnataka and showed that they were making stock transfers to other states or high sea sales, which attracts no sales tax.
