Full copy of true-PDF in English version (including equations, symbols, images, flow-chart, tables, and figures etc.) will be manually/carefully translated upon your order.Liquefied petroleum gases ICS 75.160.30 E46 National Standards of People's Republic of China Replacing GB 11174-1997, GB 9052.1-1998 liquefied petroleum gas Issued on. 2011-12-30 2012-07-01 implementation Administration of Quality Supervision, Inspection and Quarantine of People's Republic of China Standardization Administration of China released ForewordThe standard Chapter 4, Chapter 6, are mandatory, the rest are recommended. This revised standard adopts ASTMD1835-2005 "LPG Specification" (in English) to develop. This standard redrafted according ASTMD1835-2005. The main technical differences between this standard and ASTMD1835-2005 criteria are as follows. --- As the standard applicable to their products mainly for industrial and domestic fuel, does not apply for an internal combustion engine fuel, this standard does not include Including ASTMD1835-2005 the "dedicated propane" variety (see the table in this edition 1, ASTMD1835-2005 Table 1); --- Domestic LPG fraction contains not only hydrocarbons but also containing olefin component, so consider the actual situation, the present standard The ASTMD1835-2005 the "butane and more components" and "pentanes and higher component" were changed to "C4 and C4 above Component "and" C5 and C5 above components "and" commodity propane and butane mixture "of" C5 and C5 above component "indicator by the" little 2.0% (volume fraction) "to" not more than 3.0% (volume fraction) "(see the table in this edition 1, ASTMD1835-2005 Table 1); --- This standard applies to our refineries and oil and gas field production of liquefied petroleum gas, and the market for gas mixing distinction, "Commodity prop Alk "increase" C3 hydrocarbon component "targets" not less than 95% "," Commodity butane "and" Commercial propane and butane mixture, "adds "C3 C4 hydrocarbon components" targets "not less than 95%" (see Table 1 in this edition); --- In order to ensure that the highest temperature in the container is less than the pressure of liquefied petroleum gas container's pressure, "a mixture of propane and butane" The "vapor pressure" indicators from "Notes to Table B" to "not more than 1380kPa" (see the table in this edition 1, ASTMD1835-2005 in Table 1); --- Taking into account of habit, "the total sulfur content of units" by a "ppm" instead of the standard "mg/m3", and in accordance with domestic production will "Total sulfur content" index reduced by about 10mg/m3 (see the table in this edition 1, ASTMD1835-2005 Table 1); --- Domestic producers are free water control, according to the actual situation, the present standard "commodity propane" to increase the "free water" indicators, taking Disappeared "humidity" indicators (see the table in this edition 1, ASTMD1835-2005 Table 1). This standard replaces GB 11174-1997 "LPG" and GB 9052.1-1998 "liquefied petroleum gas fields." This standard GB 11174-1997 and GB 9052.1-1998 standard for the integration of a revised standard. This standard compared with GB 11174-1997, the main changes are as follows. --- Added "propane commodity" and "commodity butane" categories LPG varieties, this standard "commodity propane and butane mixture" is equivalent to GB 11174-1997 provisions of liquefied petroleum gas products; (see the table in this edition 1, GB 11174-1997 Table 1); --- Increased (see Chapter 3 edition) chapter "Classification and labeling"; --- To increase the "reserve sample" clause (see this edition 7.2); --- Added "hydrogen sulfide" indicator (see Table 1 in this edition); --- Increased "C3 C4 hydrocarbon components" targets "not less than 95%" (see Table 1 in this edition). This standard compared with GB 9052.1-1998, the main changes are as follows. --- In the GB 9052.1-1998 "butane and more components" and "pentanes and higher component" were changed to "C4 and C4 or more groups Minute "and" C5 and C5 or more components "(see the table in this edition 1, GB 9052.1-1998 Table 1); --- This standard "commodity propane and butane mixture" and "vapor pressure" from "not more than 1430kPa" to "not more than 1380kPa" (see Excerpts in Table 1, GB 9052.1-1998 Table 1); --- "The total sulfur content of units" by a "ppm" instead of the standard "mg/m3", and to reduce the "total sulfur content" index of about 10mg/m3 (See the table in this edition 1, GB 9052.1-1998 Table 1); --- Increased (see Chapter 3 edition) chapter "Classification and labeling"; --- GB 9052.1-1998 deleted in the "Definitions" chapter (see Chapter 3 GB 9052.1-1998); --- Added "hydrogen sulfide" indicator (see Table 1 in this edition); --- "Goods Propane" variety adds "free water" indicators (see Table 1 in this edition); --- "Commodity propane," increase "C3 hydrocarbon component" targets "not less than 95%", "Commodity butane" and "Commercial propane and butane mixture" Increase "C3 C4 hydrocarbon components" targets "not less than 95%" (see Table 1 in this edition). This standard by the National Standardization Technical Committee on products and lubricant oil (SAC/TC280) proposed. This standard by the National Standardization Technical Committee of petroleum products lubricants oil and lubricants and fuels Technical Committee (SAC / TC280/SC1) centralized. This standard was drafted. China Research Institute of Petroleum Corp. Petrochemical, China Petroleum & Chemical Corporation nine Jiang Branch, China Petroleum Engineering Co., Ltd. in North China Branch. The main drafters of this standard. Chen Liqing, dragon Li, in the forest, Zhangyi Gui, Guo Huijun. This standard replaces the standards previously issued as follows. --- GB 11174-1989, GB 11174-1997; --- GB 9052.1-1988, GB 9052.1-1998. liquefied petroleum gas Warning.
