The world's first lignite coal-water slurry gasification project
China drying wire Reuters July 31, Datang Hulunbeier fertilizer companies 18 • 30 projects all through the process, the first batch of urea product success off the assembly line. This is the world's first brown coal coal slurry gasification process project. It is reported that the total investment for the 18•30 project was 1.94 billion yuan, which began on May 27, 2008. After production, it will produce 180,000 tons of synthetic ammonia and 300,000 tons of urea annually. The core technology of this project is the non-slag-slag slag coal gasification staged gasification process. Based on the digestion and absorption of Texaco coal-water slurry gasification technology, the method of using oxygen to classify the gasification furnace is a domestically developed method. The new practical coal gasification technology. Syngas purification adopts low-temperature methanol washing combined with liquid nitrogen washing process, ammonia synthesis adopts low-pressure synthesis process, and urea plant adopts improved carbon dioxide gas extraction process. The overall process has the characteristics of high production intensity, stable production and operation, high operating rate, and low emission of “three wastesâ€.
Nickel Based Laser
Cladding Powder
Ni base alloy
powder is mainly made of NiCrBSi or NiBSi. Ni-based self-fluxing powder has
good wettability, corrosion resistance and high temperature self-lubricating
effect, and is used in components with heat resistance, corrosion resistance and
thermal fatigue resistance. In general Ni35,Ni45,Ni60 etc can be used for laser
cladding, the No means hardness of powder. Inconel 625 and 718 has good
corrosion property under higher temperature, also widely used for laser
cladding process.
Cobalt based Laser
Cladding Powder
Cobalt-based alloy
powder is the cemented carbide resistant to various types of wear and corrosion
as well as high temperature oxidation. That is, the so-called
cobalt-chromium-tungsten (molybdenum) alloy or Stellite alloy cobalt-based
alloy is mainly composed of cobalt, containing a considerable amount of nickel,
chromium, tungsten and a small amount of molybdenum, niobium, tantalum,
titanium, Alloying elements such as lanthanum, and occasionally a class of
alloys containing iron.
Co-based self-fluxing
alloys have good high temperature performance and wear resistance and corrosion
resistance, and are used in petrochemical power, metallurgy and other
industrial fields where they are wear-resistant, corrosion-resistant and
high-temperature resistant.
Iron based Laser
Cladding Powder
The work pieces
required for laser cladding and manufacturing in the actual industry are mainly
carbon steel and cast steel. The Fe-based alloy is close to the base material
in composition and has good wettability. The advantage of Fe base powder is
lower cost and good wear resistant of cladding layer. As a result, it`s the
most widely used for laser cladding process. It is suitable for parts that
require local wear resistance and are easily deformed.
WC blended Laser
Cladding Powder
Tungsten carbide blended with Ni alloy powder is the best
choice for wear resistant work piece. This unique process can bring excellent
wear, corrosion and high temperature resistant. Our blend powder can achieve
different portion of WC from 35% to 60% without crack under suitable cladding
parameter.
