Combustion, waste handling

SpiHs should be confined and prevented from entering water sources. Smother with foam and take up residue with an absorbent and put into dmms for disposal. The suggested method of disposal is incineration at an approved waste handling facHity in a system equipped with a combustion gas scmbber system (23). 

Plutonium-contaminated wastes, which mainly comprise paper, gloves, and contaminated, unserviceable equipment fix)m the maintenance of plants handling plutonium, can be treated in the following ways combustible waste—incineration and acid digestion and noncombustible waste— decontamination by electropolishing or ultrasonic washing. 

Volume reduction of concentrated evaporator bottoms, which may include boric acid wastes, laundry wastes, chemical wastes, and other floor drain wastes, is accomplished in the radwaste volume reduction system. The major components of the system are the crystallizer chamber and recirculation system, condenser, and vacuum pump system. The crystallizer chamber consists of a conical tank and an inner circular baffle to separate solid crystals from a clear recycle stream. Combustible wastes such as clothing, filter cartridges, and wood are volume-reduced in the radwaste incinerator. Solidification of volume-reduced wastes and other low-level radioactive wastes, such as spent resins and contaminated tools, is performed in the cement solidification system. The major components of the cement solidification system include the high shear radwaste mixer, waste dispensing system, flush water recycle steam, cement storage and feed system, and the container handling system. 

What records Fire prevention plan must include o list of workplace fire hazards o procedures to handle and store hazardous materials o potential ignition sources and appropriate fire protection o procedures to control accumulations of fiammable and combustible wastes o procedures for maintenance of safeguards installed on heat-producing equipment o names and job titles of individuals who control fuel source hazards Written plan is required for employers with 11 or more employees Verbal plan is allowed for employers with 10 or fewer employees... 

Waste Disposal. Because of its low Boiling poiat and high, toxicity, measures must be taken to prevent the entrance of phosgene iato drains or sewers. If recycle of phosgene is not feasible, phosgene waste can be handled by one of the decomposition methods mentioned above, ie, caustic scmbbiag, moist activated carbon towers, or combustion. 

In the post-combustion chamber temperatures of 900 °C to 1200 °C are reached. The kiln can - like any rotary kihi - handle solid, fluid and gaseous waste streams. Based on the heat capacity of the waste, halogen content, and potential slag formation, an optimal mixture of wastes is determined. By choosing the feed carefully, production of high-quality HCl can be assured. Furthermore, in this way a minimum formation of dioxins and furans can be ensured. 

In 1998, the DOE prepared a cost estimate of a 10-ton/day DC arc system. The system includes a furnace, waste feed system, off-gas treatment system, secondary combustion chamber, power supplies (arc power, glass overflow heating system, and metals drain), instrumentation, control systems, and product removal and handling systems. Site permitting costs and site preparation costs were also estimated (D207307). These estimates are summarized in Tables 1 and 2. 

A 2002 study reports the use of a microreactor system to increase rate of production of EO (72). The use of microreactors eliminates the formation of hot spots that are common in large reactor systems. Hot spots commonly affect selectivities by increasing the amount of combustion products formed. Microreactor systems also make harmful waste products easier to handle and limit the size of explosions if they occur.
