What Chemical Reaction Results in Implosion? - GlobalSpec
2012年1月17日 · A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. Chemical reactions can be either spontaneous , requiring no input of energy , or non-spontaneous, often coming about only after the input of some type of energy, viz. heat , light or electricity .
Hydrogen Sulphide and Steam Reaction? - CR4 Discussion Thread
2009年2月24日 · No, there isn't. H 2 S and H 2 O are in intimate contact in volcanic processes that occur naturally, and there isn't a reaction between them. To make H 2 SO 4 one needs to make SO 3 first, which requires O 2 and something to initiate a combustion reaction. SO 3 dissolved in liquid H 2 O makes H 2 SO 4.
ammonia water reaction when 316 stainless steel is used
2010年11月24日 · Good Answers: 792. # 3. Re: ammonia water reaction when 316 stainless steel is used. 11/24/2010 8:02 PM. If the water and the ammonia are separate to start with, there is a physical (not chemical) reaction of the ammonia being absorbed into the water. SS316 is resistant to this (various tables giving it an A rating). __________________.
Galvanic Reaction Between Stainless Steel and Aluminum
2007年4月5日 · Re: Galvanic Reaction Between Stainless Steel and Aluminum. 04/06/2007 7:50 AM. Aluminium will be highly anodic to the stainless steel cathode; it is slightly less anodic to the copper. The rule is the anode should be larger than the cathode; this is employed for standard radiators for heating. The radiator panel will be steel, and the water ...
Diesel Fuel and Galvanized Steel Pipes - CR4 Discussion Thread
11/25/2008 3:49 PM. Do not store diesel fuel in galvanized containers because the fuel may dissolve the zinc coating, which can then remain in solution until deposited in the pump or injectors. It is the sulfer in the fuel which attacks the Zinc in the galvanized steel. I would suspect the tank supplier which uses galvanized tanks must put some ...
Killed Carbon Steel - CR4 Discussion Thread - GlobalSpec
2010年10月30日 · No chemical reaction will take place through steam. We use killed steel for low temp. service due to its higher impact strength at lower temperatures as compared to ordinary steel. If you are talking about piping, A-106 Gr.B or API-5L Gr. B seamless quality of piping along with corresponding fittings, flanges, etc. are suitable for the above ...
Cathodic Protection Monitoring Device.. Alexander Cell
2010年3月9日 · This is also a simple description of a dry cell battery. Both produce electrical current by chemical reaction. We control the discharge by breaking the circuit of a dry cell battery and we control corrosion on pipelines by coating the steel. We can also control the corrosion reaction of a dry cell battery using a battery charger.
Dissolved Oxygen in Boiler Feed Water - CR4 Discussion Thread
2007年4月4日 · DO2 (dissolved oxygen), is one of the important factor in BFW to be removed before fed to boiler. We have usual water tratement chemical as O2 scavanger (By GE BEtz), this is being dosed in Deaerator neck. We analyse the DO2 at BFW pump suction point, with online analyser. The online analyser always showing very high values.
Difference between Diffusion and Absorption - CR4 Discussion …
2007年4月9日 · Absorption of a chemical (along with possible chemical reaction ) may take place typically by a medium with a large surface area (although the technical interaction my also involve surface adsorption (not strictly absorption), but it usually due to the absorbed chemical entering into voids and being trapped there, since diffusion out of those ...
Oppau Explosion – Ammonium Nitrate’s Deadly Beginning
2012年6月13日 · The first of these was at a BASF chemical plant in Oppau, a suburb of Ludwigshafen Germany. It was there that the unfortunate discovery of ammonium nitrate's explosion potential led to the deaths of over 500 people. It was September 21, 1921 at the BASF plant when a small dynamite charge set off a massive explosion in the storage of 4,500 tons ...
