摘要

Issues of safety, liability and environment associated with handling, storage and disposal of odorant waste are becoming very important for operations of natural gas industry. This paper is intended to provide information on technologies, equipment and procedures involved in decommissioning of odorant facilities and thermal treatment of odorant wastes which meets most stringent requirements of Gas Industry. Capable of treating wastes such as soils, drums, debris, rags and equipment contaminated with odorant, system used by Material Resource Recovery Inc. has the ability to treat odorant tanks up to a length of 26 feet. Decommissioning of odorant facilities includes site assessment, risk evaluation, procedure development and decommissioning plan development. Main goal of this phase is to prepare all equipment, piping, debris and liquids and odorant tanks for transport into our facility for final treatment and odorant destruction. Thermal oxidation, (incineration) combined with a two-phase treatment process, ensures the safe and efficient destruction of odorant wastes. Phase I involves evaporation of odorant at low temperature (<220℃) and subsequent incineration of vapors in the primary and afterburner units. Phase II involves the incremental elevation of temperature to 600℃ for the complete destruction of all remaining residues. In both Phase I and II, all gases are treated through a quenching tower and wet scrubber for SO_2 removal. Measurement of SO_2 concentrations entering and exiting the wet scrubber are used to measure the continuous efficiency of the scrubber, as well as, determine the completion of Phase I and the start of Phase II. A two phase treatment process ensures that the risk of explosions and uncontrolled exothermic reactions are eliminated. An after-burner unit with a retention time of approximately 2 seconds and a minimum operating temperature of 980℃ allows for the complete destruction of all organics. An Anderson 2000 wet scrubber with a minimum operating efficiency of 95% ensures effective removal of SO_2.
