2.A Equipment

Heat exchangers as follows and specially designed components therefore: Plate-fin heat exchangers with a surface/volume ratio greater than 500 m^(2)/m^(3), specially designed for pre-cooling of natural gas; Coil-wound heat exchangers specially designed for liquefaction or sub-cooling of natural gas. Cryogenic pumps for the transport of media at a temperature below – 120 °C having a transport capacity of more than 500 m^(3)/h and specially designed components therefore. 'Coldbox' and 'coldbox' equipment not specified by 2.A.1. Technical Note: 'Coldbox' equipment' refers to a specially designed construction, which is specific for LNG plants and incorporates the process stage of liquefaction. The 'coldbox' comprises heat exchangers, piping, other instrumentation and thermal insulators. The temperature inside the 'coldbox' is below – 120 °C (conditions for condensation of natural gas). The function of the 'coldbox' is the thermal insulation of the above described equipment. Equipment for shipping terminals of liquefied gases having a temperature below – 120 °C and specially designed components therefore. Flexible and non-flexible transfer line having a diameter greater than 50 mm for the transport of media below – 120 °C. Maritime vessels specially designed for the transport of LNG. Electrostatic desalters specially designed to remove contaminants such as salts, solids and water from crude oil and specially designed components therefore. All crackers, including hydrocrackers, and cokers, specially designed for conversion of vacuum gas oils or vacuum residuum, and specially designed components therefore. Hydrotreaters specially designed for desulphurisation of gasoline, diesel cuts and kerosene and specially designed components therefore. Catalytic reformers specially designed for conversion of desulphurised gasoline into high-octane gasoline, and specially designed components therefore. Refinery units for C5-C6 cuts isomerisation, and refinery units for alkylation of light olefins, to improve the octane index of the hydrocarbon cuts. Pumps specially designed for the transport of crude oil and fuels, having a capacity of 50 m^(3)/h or more and specially designed components therefore. Tubes with an outer diameter of 0,2 m or more and made from any of the following materials: Stainless steels with 23 % chromium or more by weight; Stainless steels and nickel bases alloys with a 'Pitting resistance equivalent' number higher than 33. Technical Note: 'Pitting resistance equivalent' (PRE) number characterises the corrosion resistance of stainless steels and nickel alloys to pitting or crevice corrosion. The pitting resistance of stainless steels and nickel alloys is primarily determined by their compositions, primarily: chromium, molybdenum, and nitrogen. The formula to calculate the PRE number is: PRE = Cr + 3,3 % Mo + 30 % N 'Pigs' (Pipeline Inspection Gauge(s)) and specially designed components therefore. Pig launchers and pig catchers for the integration or removing of pigs. Technical Note: 'Pig' is a device typically used for cleaning or inspection of a pipeline from inside (corrosion state or crack formation) and is propelled by the pressure of the product in the pipeline. Tanks for the storage of crude oil and fuels with a volume greater than 1000 m^(3) (1000000 litres) as follows, and specially designed components therefore: fixed roof tanks; floating roof tanks. Subsea flexible pipes specially designed for the transportation of hydrocarbons and injection fluids, water or gas, having a diameter greater than 50 mm. Flexible pipes used for high pressure for topside and subsea application. Isomeration equipment specially designed for production of high-octane gasoline based on light hydrocarbons as feed, and specially designed components therefore.
