Market participants said this week that due to changes in the winter and summer gasoline specifications in northwestern Europe, some major British oil refiners have started exporting butane cargo steadily, which will put butane prices under pressure. Wednesday's high-quality offshore butane cargo price was 93% of the naphtha price (CIF Northwest Europe) of 999.25 USdollars/ton, and the price of butane cargo on April 11 was 95% of the naphtha price. Naphtha prices are 1056 US dollars / ton. Traders said that Shell's 272,000 barrels/day Stanlow refinery, Murco's 105682 barrels/day Milford Haven refinery, and ExxonMobil's 329,500 barrels/day Fawley refinery have started exporting butane offshore trade ships. The average export scale is between 1,000 tons and 3,000 tons.
Oxygen machine is one kind of product producing oxygen from air. There are small oxygen machine providing 3-10 liter per minute flow, mainly using at home. There are also big Industrial Oxygen Generator providing oxygen with flow rate up to 10000 Nm3/hr. From technology, there are pressure swing adsorption(PSA) , vacuum swing adsorptio (VSA)and cryogenic three types. The PSA type is for smaller flow rate within 300 Nm3/hr, from 300 to 3000 Nm3/hr, it is ok to use VSA technology. For bigger flow rate, normally use cryogenic Oxygen Plant.
No matter what technology, these oxygen machines all use oxygen in the air. All use Air Compressor to provide raw material, compressed air. Then the compressed air will be cleaned, dried for futher separation. After separation, the produced oxygen either directly goes to oxygen using point or they are compressed into high pressure such as 150 bars or 200 bars, then stored in cylinders and tanks.
