Feature Article: Securing Transportation of Ammonia

17/6/2021· This puts organs like eyes and lungs at risk, as well as skin, which could be burned or even frostbitten if in contact with a liquefied form of ammonia. Treatment of the exposed areas includes washing with water and moving to fresh air. Large quantities of anhydrous ammonia are typically transported in a variety of conveyances.

Guidelines for: Suggested Safety and Operating Procedures

(3) Visually inspect and pressure test all transfer hoses and fittings. (4) There should be a functional permanent or portable eye wash and shower available. (5) Know what to do, and where to go if an ammonia release occurs. (6) Never leave the transfer process unattended. Monitor temperatures and pressures during the pump-out and transfer.

of ammonia-rated hosing in a system is limited to the transfer connections between the fixed storage system piping and nurse tank, rail, and cargo tank. Hosing must be ammonia-rated, have a minimum working pressure of 350 psig (1750 psig burst pressure). Hose asselies, when made up, must be capable of withstanding a test pressure of 500 psig.


Table 2 lists the mass of ammonia for different pipe sizes in liquid lines, and also rule-of-thu values for wet suction lines. These may be used for calculating the charge necessary. For liquid recirculating systems, the low-pressure liquid line volume is doubled

Heat Pipes for Thermal Management | ACT

Heat Pipes are one of the most efficient ways to move heat, or thermal energy, from one point to another. These two-phase systems are typically used to cool areas or materials, even in outer space. Heat pipes were first developed for use by Los Alamos National Laboratory to supply heat to and remove waste heat from energy conversion systems.

An Alternate View on Pipelines — Transport Ammonia not Crude

11/7/2016· Ammonia is one of the most manufactured commodities in the world and is used both as an industrial feedstock and as a fertilizer. It is commonly made from brown sources (like natural gas) but it is ideally suited to be made from green sources (like wind, solar, and hydroelectric power), and it gives us the ability to store and transport electricity economically in …

Liquid Ammonia Transport Through Pipeline - Student

11/1/2009· Liquid Ammonia Transport Through Pipeline - posted in Student: hello,I have a lot of confusion regarding the topic. So let me start with the situation,me n my teammates are assign to design a transport system using pipline for transporting ammonia from a storage tank to a plant which is 500metres away with the rate of 500,000 tones anually and in need to consider the …

High-Performance Insulation for Ammonia Refrigeration

1/5/2007· Excessive pipe corrosion can even lead to pipe failure and release of the contents into the environment - a critical concern, given the hazards and regulations associated with an ammonia leak. One alternative for insulating ammonia lines and storage vessels is an insulation system consisting of extruded polystyrene in conjunction with polyvinylidene chloride (PVDC) …


Commercially, ammonia is made by coining free nitrogen and hydrogen gases under high pressure and temperature in the presence of a alyst. The process most commonly used is the Harber-Bosch method. Anhydrous ammonia is the liquid form of pure ammonia gas, technically water-free, and the substance used universally as an industrial refrigerant.

Heat Pipe Technology | Boyd Corporation

Heat pipes are the most common passive, capillary-driven of the two-phase systems. Two-phase heat transfer involves the liquid-vapor phase change (boiling/evaporation and condensation) of a working fluid. The heat pipe technology industry leader, Aavid, Thermal Division of Boyd Corporation has specialized in the design, development and
