Lethbridge Herald, The (Newspaper) - September 1, 1971, Lethbridge, Alberta J8 THE LETHBRIDCE HERALD Wednesday, September 1, 1971 r THERMAL DESTRUCTOR This is the part of ihe thermal destructor that accomplishes the aclual burning. Design was done largely by Waller Montgomery, esla- blishment engineer at ORES. The combustion chamber, 14 feet long. Iks scrubbing tower al the far end and control equip- ment was supplied by Pyrotherm Equipment Ltd. of Bur- linglon, Ont. The chamber is seven feet in diameter and DESTRUCTOR INTERIOR With inside temperatures in Ihe thermal destructor reaching degrees, the unit must be well-lined. This picture was taken during the construction phase. It shows the layers of brick lining necessary to contain the blue-hot flame necessary to achieve complete destruction of the DDT. Suffieid DDT destructor in use By HERB JOHNSON Slaff Writer A study is nmv under at Defence Research Establish- ment SuffieM (DRES) on Ihe feasibility of expanding the sta- tion's operations in the field of disposal of pollutants. Right now DEES is jusL get- ting started. A new thermal de- structor which is able to burn a mixture of DDT and kerosene is in operatiou and as soon as all the "bugs" are out. the destruc- tor will go into 24 hour a-clay operation. It is hoped UIDI 107.000 gal- lons of the mixture stocks held by various Canadian forces bases in the country u'ill IK safely destroyed by the end of the year. Disposal lias been a problem since DDT was banned by Ihe federal government and the de- structor is a safe and extremely dean way of getting rid of it. Clayton Iverson, DRES direc- tor-general, said tlie sta Lion was looking to "broader involve- ment" in the entire field of dis- posal of pollutants and contami- nants. First responsibility would be to stocks held by the depart- ment of national defence. Mr. Iverson said DRES might pos- sibly become a national disposal site for pollutants for DND. Plans for involving other lev- els of government are a lilllc of mustard gas which has been less well defined. He said DRES was definitely not looking for a lot of unwanted chemicals right now from anyone and everyone, because Ihe station al present was simply not equipped to handle Ihem The DDT destructor was lim- ited in what it could do, he said, and other disposal melh- ods were being investigated for other chemicals Burial, stor- age and destruction were all being looked al. Data on the feasibility of ex- panding DRES operations v ould be available in Uie next few months, he said. One particular prohlen: is a stockpile of 1.3 million pounds stored at Suffieid since the Sec- ond World War. Stored in lead-lined concrete vaults, the gas is safe" right where it is. The problem, .said Mr. Ivorson, is lliat Ui9re has been public pres- sure to get rid of it and [his may become absolutely neces- sary if Canada should sign an international agreement, n o w under negotiation, that would ban the use of biological and chemical agents in warfare. The DDT destructor could be used, if modified at a cost nf about Labor costs in destroying the gas would also be high because would have to wear rubber suits for protection and could work for only short pericds. Burning the muslard gas in an open pit would be much cheaper, but would produce some pollution. The problem right now is to decide how much public should be spent lo dcslroy the gas, be si'id. lion of unwanted chemicals Ls an expensive busi- ness. The DDT destructor gets rid of DDT at a cosl of about 25 cents a gallon, if it is run- ning all the time. A conservative estimate on destroying the mustard gas stocks is if il is to ba done with no pollu- tion. CLEAN BURNING The of whits smoke issuing from the scrubbing tower stack is all that remains of the DDf-kerosene mixture after it has gone through the thermal destructor. The incinerator's degree Fahrenheit temperature completely destroys the mixlure. All that will remain after burning department of national defence stocks of gallons of Ihe mixlurc will be about one-sixth of a cup of DDT pollution equivalent to Ihe amount prodjced by the low-temperature burning of a small pan only partly filled with DDT-kerosene. OPEN BURNING This is ihe result when the DDT- kerosene mixture is burned in on open pan. The low temperature is not high enough IQ dcslroy Ihe DDT, which floats out into the air.
