What are reformer tubes made of?
What are reformer tubes made of?
The reformer tubes are full of nickel catalyst, which triggers a reaction causing the methane in natural gas to react with water vapor to form hydrogen, carbon monoxide, and carbon dioxide.
What is reformer tube?
Reformer tubes are heat-resistant cast alloy tubes used in steam reformer furnaces for producing hydrogen, an essential material for such processes as desulfurization at petroleum refining plants, ammonia synthesis for fertilizer production, methanol production, and direct reduced iron production.
What is creep in reformer tubes?
Creep is a progressive damage process, which produces a physical change in diameter of the catalyst tube with increased service time. As creep progresses, voids will nucleate at grain boundaries within the material and with further service exposure the creep process initiates micro-cracks in the tube.
What does a reformer do in a refinery?
The purpose of the reformer is to upgrade heavy naphtha into a high-value gasoline blend stock by raising its octane. The primary product of the reformer is reformate. However, it also generates large amounts of hydrogen that can be used in the hydrotreaters and hydrocrackers.
Can reformer is used for?
What catalyst is used in reforming?
platinum
Catalytic reforming uses a catalyst, usually platinum, to produce a similar result. Mixed with hydrogen, naphtha is heated and passed over pellets of catalyst in a series of reactors, under high pressure, producing high-octane gasoline.
What is reformer process?
reforming, in chemistry, processing technique by which the molecular structure of a hydrocarbon is rearranged to alter its properties. The process is frequently applied to low-quality gasoline stocks to improve their combustion characteristics.
What is reformer in petrochemical industry?
The reformer is a critical unit for making high-quality gasoline and avoiding production of low-octane heavy naphtha. Also, as sulfur specifications have tightened, forcing greater use of hydrotreating, the value of the hydrogen produced by the reformer has increased.
What are the major products of catalytic reformer?
Products from catalytic reforming include high-octane gasoline useful as automobile fuel, aromatics, and hydrogen. The typical reactions in catalytic reforming are dehydrocyclization, isomerization, and dehydrogenation.
How does a refinery reformer work?
Which catalyst is used in reforming?
What does a reformer produce?
A methane reformer is a device based on steam reforming, autothermal reforming or partial oxidation and is a type of chemical synthesis which can produce pure hydrogen gas from methane using a catalyst.
