Outlines Development Of

Inert Gas Systems

Foster Wheeler Boiler Corpora- tion, Livingston, N.J., is offering "Taming the Explosion Hazard," an article reprint from the Foster

Wheeler organization's technical publication, "Heat Engineering."

The article outlines the develop- ment of inert gas systems in blanketing hazardous cargoes, then goes on to describe the two configurations offered under li- cense from Moss Rosenberg of

Norway.

Within recent years, inert gas systems have drawn increasing attention from the maritime com- munity as a means of protecting crude oil and liquefied gas tank- ers from fire and explosion. A recent proposal would require all tankers of more than 20,000 dwt calling on U.S. ports to be equipped with these systems.

Properly operated, inert gas systems have prevented explo- sions in the cargo tanks of ves_ sels. This was graphically demon- strated as early as World War II, when the tankers of one operator never suffered a cargo explosion, even when torpedoed.

Last year, Foster Wheeler Boil- er Corporation was licensed by

Moss Rosenberg Verft A.S. of

Norway to manufacture and sell the inert gas systems for marine and industrial applications. FWBC currently markets these units in the United States, Canada, Cen- tral and South America. A wholly owned subsidiary of Foster Wheel- er Corporation, FWBC supplies marine steam generators to the world's fleets and industrial boil- ers for a wide range of stationary applications.

As described in the Foster

Wheeler article, two basic inert gas system configurations are available. The simplest takes stack gas from a steam gener- ator or furnace and cools and scrubs the gas stream of con- taminants. Aboard ship, seawater may be used as the scrubbing medium. The clean, inert gas is then directed by blowers and a piping distribution system to the areas to be inerted. This design is suitable only if the quality of the flue gas is suitable and the volume from the boiler or furnace is sufficient to provide the amount of inert gas needed for cargo blanketing and leakage makeup.

A second, somewhat more so- phisticated design, burns light fuel oil under controlled condi- tions in a special combustion chamber. The resulting gases are scrubbed and directed to the areas to be inerted.

In both designs, monitoring equipment and automatic controls assure that the oxygen content of the gas from the scrubbers is well below that needed to sustain combustion.

Jean F. Boulin will manage Red

Fox's East Coast Region and operate out of offices in West

Redding, Conn. Western regional manager, headquartered in Carls- bad, Calif., will be Robert J. Buza.

And heading the Gulf Coast Re- gion will be John Talluto, whose home base will be New Orleans,

La. All three men will be responsi- ble for both the sale and the serv- ice of Red Fox sewage treatment devices in their respective regions.

Red Fox Industries is involved in several aspects of the marine and oilfield service industries. The company manufactures Type II marine sanitation devices in 22 standard sizes to accommodate crew sizes from two to 2,500.

All Red Fox MSD's exceed EPA standards, U.S. Coast Guard reg- ulations, and IMCO requirements.
