i <br /> Harding Lawson Associates <br /> goes though a desorption process. The desorption process <br /> condenses the hydrocarbon product, to a liquid form which can <br />� then be either recycled or disposed as liquid waste. The resin <br /> bed is regenerated to 99.99 percent capacity without the need for <br /> tadditional resin. <br /> This process presents many ideal operating conditions. The <br /> operating costs associated with regeneration and replacement of <br /> ' the reactor bed are low with the highest costs being the <br /> increased electrical consumption during the desorption phase and <br /> 1 the transportation of the few drums of liquid. The process is <br /> ' also environmentally responsible, because the waste products can <br /> be recycled and there are no air emissions released. In <br /> comparison, the desorption process for activated carbon does not <br /> recycle the waste product, requires off-site transport and <br /> ' treatment, releases large quantities of carbon dioxide, and only <br /> 90 percent of the carbon can be reused at a lesser efficiency. <br /> The problems associated with any new technology is the <br /> ' question of product reliability, and the availability of vendors <br /> to supply and maintain the equipment. This may lead to higher <br /> ' installation and repair costs. Initial costs are higher than <br /> ' conventional carbon technology and the electrical operating costs <br /> are unknown. Due to the anticipated length of this prosect, this <br /> new technology could be more costly. Therefore, we do not <br /> recommend this method of treatment though it could be more <br /> ' efficient. Costs of the long term operation of such equipment <br /> ' 16 <br />
