Description:
The report describes recent developments in the control of methyl bromide (MeBr) and discusses technical considerations and requirements for and economic feasibility of recovery. (NOTE: MeBr, fumigant for agricultural commodities, is an ozone depleting chemical. The U.S. EPA has banned its use beginning in 2001. In some applications, a suitable substitute for MeBr as not been found, so the report discusses an exempted use of MeBr with capture and recovery or recycle for some applications.) The primary focus of the report is on quarantine applications using MeBr. Two of the most promising approaches to recovery, recycle, and reuse continue to be physical adsorption on a solid sorbent and cryogenic condensation. In addition to discussing these technologies, the report identifies some of the critical considerations for process economics and remaining information gaps. The review concludes that recovery, recycle, and reuse appear to be feasible, have not been unequivocally proven to be so, and there is little current incentive to pursue such technologies unless there is hope of exemptions to or recision of the MeBr ban.
