    Steam and Condensate - A basic overview of a steam system

    If steam is pressurised, it will occupy less space. Steam boilers are usually operated under pressure, so that more steam can be produced by a smaller boiler and transferred to the point of use using small bore pipework. When required, the steam pressure is reduced at the point of use. As long as the amount of steam being produced in the boiler

    Major Accidents at Chemical/Refinery Plants :: Hazardous

    The steam boilers were tripped off, which led to a loss of steam for the refinery. The refinery was shutdown immediately with much of the offgas going to the flares. The flares were overwhelmed and created a lot of smoke and decreased the overall efficiency of the flares. The refinery lost steam and had an emergency shutdown.

    Oil refinery - Wikipedia

    An oil refinery or petroleum refinery is an industrial process plant where crude oil is transformed and refined into useful products such as petroleum naphtha, gasoline, diesel fuel, asphalt base, heating oil, kerosene, liquefied petroleum gas, jet fuel and fuel oils. Petrochemicals feed stock like ethylene and propylene can also be produced directly by cracking crude oil without the need of

    Aug 17, 2019· If there is more than 2 kg/tile of Steam in the boiler chamber AND the Steam's temperature is above 115 C, pump the Steam out - it's rocket-ready. (Make sure it can't cool off on the way to a Rocket, but everything's fine once the Steam's inside safely.) If there is less than 2 kg/tile of Steam in the boiler chamber, add more Water.

    Hydrogen Production By Steam Reforming - Chemical

    May 01, 2010· (Page 1) Steam reforming of natural gas at petroleum refining facilities is the predominant means of producing hydrogen in the chemical process industries (CPI). Because hydrogen needs within various sectors of the CPI are at their highest levels in history, and are continuing to grow, an understanding of this method of hydrogen production and purification can be useful

    Most steam used in the refinery is condensed to water in various types of heat exchangers. The condensate is reused as boiler feedwater or discharged to wastewater treatment. When refinery steam is also used to drive steam turbine generators to produce electricity, the steam must be produced at much higher pressure than required for process steam.
