A gas sensor is provided, having an electrolyte membrane, a sensing electrode, a counter electrode, a diffusion barrier for controlling access of gases to the sensing electrode, and in situ means for removing molecular oxygen from the gases to which the sensing electrode is being exposed.
dition of enrichment (hydrocarbon) gas, which is usually done at the furnace. Nitrogen/Methanol or Nitrogen/ Hydrogen Atmospheres An endothermic equivalent gas atmo-sphere can be obtained by cracking liquid methanol (methyl alcohol) and combin-ing it with nitrogen (Eq. 1), using a blend of 40% nitrogen and 60% methanol (dis-sociated). (1) CH 3
The latter method extends the atmosphere protection to the lower range of annealing temperatures. Present results may assist heat treaters in optimizing their neutral hardening operations. Introduction A critical consideration in heat treatments is the type, consistency and control of the furnace atmosphere. The purpose of a furnace
I want to use nitrogen atmosphere to heat aluminium under the reducing atmosphere of hydrogen gas in an electric tube furnace at 600C. The technician in-charge has fear that it may result in
Hydrogen furnace a kind of heating equipment.,also known as hydrogen furnace.which charge into hydrogen or hydrogen, nitrogen mixture gas (hydrogen content >5%) as a protective atmosphere. With 2 types instructure:Vertical and Horizontal type.
We then subject the above-mentioned intermediate products to a two-stage reduction process in the presence of hydrogen in order to obtain metallic molybdenum powder. We reduce molybdenum trioxide in a hydrogen atmosphere to obtain a slightly reduced molybdenum oxide (MoO2) which has a typical reddy-brown color.
Jan 01, 2015 · Gas-phase nucleation is the basis for a gas-to-solid particle transportation process. In the present synthesis method, Al and Mg atoms are evaporated from the raw materials with the assistance of high temperature arc plasma. Due to presence of cooling gas, large thermal gradient are created between the hot arc and cooling chamber.
Linde sell a wide range of refrigerant gases for air conditioning and refrigeration applications and offer the full range of package sizes incl. cylinders, drums and bulk deliveries along with various environmental lifecycle solutions to ensure responsible use and recovery/destruction of all refrigerants.
Hydrogen (H2) is an odourless, colourless and tasteless gas that is produced through natural gas steam reforming or the electrolysis of water. Lighter than air, it burns with an invisible, clean (carbon-free and soot-free) flame. It is the only fuel gas that does not contain any carbon atoms. H2 has the highest thermal conductivity of all gases.

It is designed for material systhesis under controlled inert gas atmosphere up to 1700.C with better temperature uniformity. The furnace consists of high quality alumina fiber brick and high quality MoSi2 heating elements,It is an ideal tool for preparing new materials like Nano,Graphene and heating /sintering Gem stone, zirconia COCR Ti Alloy which requires heat treatment under inert gas or
Sep 12, 2012 · Preparations began for the furnace atmosphere changeover to take place during a maintenance turnaround. Praxair coordinated the resources for the design of the hydrogen and nitrogen system foundations and assisted with the engineering of the hydrogen and nitrogen distribution lines from the supply systems to the furnaces.

Here the cooling energy can be supplied in the form of liquid nitrogen, which efficiently condenses VOCs from the waste gas stream. These can then be easily captured and re-routed back into the process or further treated. Now in gaseous form, the nitrogen can be used for other applications such as inerting.
Rapid Hot Pressing. We use machines with inductive and direct heating for rapid consolidation with heating rates of 100 - 300 K/minute. Our direct heating technology is also known as SPS - Spark Plasma Sintering or FAST - Field Assisted Sintering. The advantage of our machine is the large manufacturing electrode size of 350 x 350 mm and a
Ex: Low Temperature Protection of Piping, may be a Case of Concurring Hazards In case of a H 2 furnace atmosphere and carbon steel piping downstream the N 2 vaporizer. If using a shutoff device, no N 2 for purging would be available for purging H 2 out of the furnace, in case of an emergency.
