1.0.2 This Code is applicable to the fire design for newly-built, expanded and reconstructed onshore oil-gas field projects, pipeline station projects, as well as the offshore oil-gas field's land terminal projects.
1.0.3 The fire design of the petroleum and gas projects must be compliant to the relevant guidelines, policies. Combining the practices, it's shall exactly deal with the relation between production and safety, positively adopts state-of-the-art fireproofing and fire-extinguishing technologies, ensure safe production and cost-effectiveness.
1.0.4 Besides the provisions of this Code, the fire design of petroleum and gas projects also must be compliant to the relevant compulsive standards.
2. Terminology
2.1 Terminologies of oil, gas and fire hazard
2.1.1 Oil
It refers to crude oil, petroleum products (gasoline, kerosene, diesel oil and naphtha, etc.), stabilized light hydrocarbon and stabilized condensate.
2.1.2 Crude oil
It refers to the liquid compound produced from the oil well, giving priority to hydrocarbon.
2.1.3 Natural gas liquid (NGL)
It's the generic term of liquid hydrocarbon compounds recovered from the natural gas but not passed through stabilizing treatment, generally including ethane, liquefied petroleum gas (LPG) and stabilized light hydrocarbon. It's also named as mixed light hydrocarbon.
2.1.4 Liquefied petroleum gas (LPG)
It's in the gaseous state under normal temperature and pressure but becomes liquid after compression or cooling. It's mainly consisted of propane, butane and their compounds.
2.1.5 Stabilized light hydrocarbon
It's abstracted from natural gas liquid (NGL) and is mainly consisted of pentane and other heavier hydrocarbon, the end boiling point shall not be higher than 190℃, under the specified vapor pressure, it allows including a little butane. It's also named as natural gasoline.
2.1.6 Gas condensate
It refers to the hydrocarbon liquid abstracted from the condensate gas but not stabilized.
2.1.7 Stabilized gas condensate
It's abstracted from the gas condensate and is mainly consisted of pentane and the other heavier hydrocarbon.
2.1.8 Liquefied natural gas (LNG))
It refers to the liquid fluid consisted of methane, together with little ethane, propane, nitrogen and other components.
2.1.9 Boil over
It refers to the water-bearing oil that has heat wave characteristics in combustion, such as crude oil, petroleum residue and heavy oil.
2.2 Terminologies of fire-fighting cooling water and fire-extinguishing system
2.2.1 Fixed fire-fighting cooling water system
It refers to the fire-fighting cooling water system consisted of fixed fire-water pond (tank), fire pump, fire water supply pipeline and fixed cooling water spray system equipped on the storage tank.
2.2.2 Semi-fixed fire-fighting cooling water system
The fixed fire water supply pipeline and hydrants are set up in the tank farm, in case of fire; the water will be pressurized by fire truck or fire pump to spray by the means of water bands and water guns.
2.2.3 Mobile fire-fighting cooling water system
No fire water source is set up in the tank farm, in case of fire, the water will be supplied by fire truck or other water sources to spray by the means of onboard water bands and water guns.
2.2.4 Low expansion foam fire-extinguishing system
It refers to the foam extinguishing system whose expansion factor is less than 20 times.
2.2.5 Fixed low expansion foam fire-extinguishing system
It refers to the low expansion foam fire-extinguishing system consisted of fixed foam fire pump, foam proportioner, foam mixing solution pipeline and the fixed air-foam generator equipped on the storage tank.
2.2.6 Semi-fixed low expansion foam fire-extinguishing system
Fixed air-foam generator is set up on the storage tank, in case of fire, the foam truck or motor pump will supply foam mixing solution through hoses.
2.2.7 Mobile low expansion foam fire-extinguishing system
In case of fire, the foam truck will provide foam through onboard hoses and foam generators.
2.2.8 Smoke fire-extinguishing system
It's consisted of smoke generator, detection and initiating device and the sprayers. In case of fire, it can automatically inject fire-extinguishing smoke to the storage tank.
2.2.9 Dry powder fire-extinguishing system
It's consisted of dry powder storage device, actuating device, pipeline, sprayer, fire alarm and interlink control device, it can automatically or manually inject powder extinguishing agents to the protected objects.
2.3 Terminologies of oil gas production facilities
2.3.1 Petroleum and gas station
It's a general designation for the station, storage, plant, farm, oil and gas well that can collect, purify, store and transport petroleum and gases. It's called petroleum and gas station or station for short.
2.3.2 Oil station
It refers to the stations that have crude oil collection, purifying treatment, storage and transportation functions, or that storage and transportation of natural gasoline and stabilized gas condensate, or that have product oil pipeline transportation functions.
2.3.3 Natural gas station
It refers to the station that has natural gas collection, transportation and purifying treatment functions.
