DESCRIPTION: For the purposes of this card, ammonia refers to solutions that are 50% ammonia or greater, ammonia anhydrous, and ammonia anhydrous liquified, unless otherwise specified. Ammonia is a toxic gas or liquid that, when concentrated, is corrosive to tissues upon contact. Exposure to ammonia in sufficient quantities can be fatal.
11/13/2004 · 2) assume that the upstream pressure does not drop with time as the ammonia escapes. Estimate the volumetric flow rate using an orifice calculation. Assume that the upstream pipe diameter is the ID of the 3" pipe for d/D. Calculate the volumetric flow rate. Convert to a mass flow rate using the conditions of the gas in the pipe.
Anhydrous ammonia, by its very nature, invites contamination by moisture. It is a fact that moisture from the air will travel into an ammonia system through a leak even while the ammonia is coming out. In critical applications, it is of utmost importance that all leaks be promptly corrected. Contamination by oil
Ammonia is a compound of nitrogen and hydrogen with the formula NH 3.The simplest pnictogen hydride, ammonia is a colourless gas with a characteristic pungent smell. It is a common nitrogenous waste, particularly among aquatic organisms, and it contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to food and fertilizers.
anhydrous ammonia. This manual summarizes the requirements of environmental and safety laws for anhydrous ammonia refrigeration system operators. A list of the federal laws and regulations related to process safety, accident prevention, emergency planning, and release reporting may be …
When anhydrous ammonia escapes to the atmosphere, it forms a mixture which may contain any or all of the following: (i) ammonia vapor; (ii) fine droplets of liquid ammonia (pure ... when the ammonia was allowed to leak slowly through a long pipe leading from the flask's vapor space, the predicted vapor
Page 2 of 10 POTENTIAL HEALTH EFFECTS Primary Routes of Entry: Inhalation, skin contact/absorption and eye contact. General Acute Exposure: Anhydrous ammonia reacts with moisture in mucosal surfaces (eyes, skin, and respiratory tract) …
The tanks are not completely filled with liquid ammonia, but might contain a headspace of at least 15% (by volume) of ammonia and inert gases. Anhydrous ammonia tanks used as fertilizer on farms may have a 3000-gallon capacity and rated at 250-psig pressure. Anhydrous ammonia tanks transported by truck and railcar have larger capacities.
Anhydrous Ammonia Storage Tank Location and Design. Stationary storage tanks for anhydrous ammonia are regulated by the U.S. Dept. of Labor and must conform to the requirements of 29CFR1910.111. They are built in accordance with the ASME Boiler and Pressure Vessel Code and are rated for 250 psig.
Power Plant SNCR/SCR Units & Ammonia Safety Measures Manufacturer’s Reprint Stationary source NOx emissions compliance was required by the Clean Air Act Amendments of 1990, on a phased in schedule based on source size. In 2005, the Clean Air Interstate Rule (CAIR) became law, affecting nearly 40,000 MW of power generation in the Eastern States.
Solve for unknown attribute. Add in the known values and hit "calculate" and the unknown attribute will be generated for you! The Ideal Gas Law: PV=nRT
7/15/2008 · Note this is a pinhole leak not a pinhead leak which would be about twice the diameter. Using dcasto's excellent formula and noting that the diameter of the pipeline and the rate through the pipeline have nothing to do with the question, unless the pipeline diameter is approaching that of a pin, the leak rate through the pinhole is about 120 SCFH.
The solubility of ammonia in water is shown in Curve 1. Ill. EFFECTS OF WATER DILUTION The pressure-temperature relationship for aqueous ammonia solutions is different than that for anhydrous ammonia. At a given pressure the saturated temperature for anhydrous ammonia will be lower than the saturated temperature for an aqueous solution.
Firefighting and Anhydrous Ammonia by Harold F. Maybeck . Original Publication 1997, Revised 2006 Holderness Fire Department, Holderness, NH. Anhydrous ammonia is the refrigerant gas used at The Holderness School Ice-Rink. ABOUT AMMONIA Ammonia is a colorless gas and it has a characteristic, pungent, choking odor.
is 29%, the volume of aqueous ammonia required is 3.4 times that of anhydrous ammonia. For 19% aqueous ammonia, the volume required is 5.3 times that of anhydrous ammonia. This difference in volume between aqueous and anhydrous ammonia feed rates will result in an increase in the quantity and size of the storage tanks

Anhydrous Ammonia Replaces 20% of Motor Gasoline and Diesel Demand (on a Ton for Ton basis) Requirement: U.S. Total Motor Fuel Consumption (2005): 640.22 MM tons Anhydrous Ammonia to Replace 20%: 128.04 MM tons U.S. Anhydrous Ammonia Production (2005): 12.00 MM tons U.S. Anhydrous Ammonia Production would have to increase by a factor of 10.67
Worst Case Scenario Calculation • Calculation of Worst Case Scenario (WCS) required for applicable sources per EPA 40 CFR part 68 (Chemical Accident Prevention rule or CAP) • WCS is the release of the largest quantity of a listed substance from a process • Also, the WCS is the release that results in the
----- HAZARDS OF AMMONIA RELEASES AT AMMONIA REFRIGERATION FACILITIES AUGUST 1998 technologies and to share its knowledge with these facilities. Region IH has conducted more than 120 audits from 1995 to the present of both large and small facilities using ammonia for refrigeration.
Ammonia refrigeration systems with 10,000 pounds or more of ammonia are a covered process subject to the requirements of the Process Safety Management Standard [29 CFR 1910.119].Many of these requirements are identified in this e-tool as possible controls and are useful as recommended practices whether or not the ammonia refrigeration system is a covered process.
