摘　　要：为防治澳大利亚主要仓储害虫,开发富氮气调技术作为熏蒸剂的辅助手段。然而,由于成本问题,一直影响其在行业推广应用。本研究利用中国长顺安达公司的先进膜分离技术,与传统的制氮技术(变压吸附/PSA)进行性能比较,在西澳Kwinana的CBH粮食港,开展实仓应用实验,以解决阻碍其推广的运营和成本问题。为满足澳大利亚严格的标准操作条件,长顺安达专业团队对港口设备进行了升级改造,目标消杀成本设定为0.50澳元/吨粮(磷化氢的高端熏蒸成本)。研究表明,旧的PSA技术的运营成本为2.43澳元/吨粮,该技术在产生和维持控制害虫所需的99%氮气浓度水平方面也显示出操作局限性。相比之下,使用膜技术制氮的成本为0.99澳元/吨粮,其他性能增益还包括运行4.5天内即可产生所需的氮气浓度,且可维持14天以完全控制害虫。Nitrogen technology has been developed as a complementary technology with fumigants,for control of key pests in Australian grain storages.However,market feedback from industry was its cost which remained as a barrier of uptake.Therefore,a commercial scale trial was set up using advanced membrane technology to assist industry overcome operational and the cost barriers for the uptake of the technology.A new generation membrane technology was sourced from Changshun Anda,a China-based company.The unit was deployed at the CBH grain port of Kwinana,Western Australia to compare performance against an older nitrogen generation technology(Pressure Swing Absorbance/PSA).To meet the strict Australian standards operating conditions the port the unit was upgraded by Changshun Anda specialist team.The target benchmark was set to$0.50 per tonne of grain(the high-end cost of a phosphine fumigation).Research demonstrated an operational cost for the older PSA technology of$2.43 per tonne of grain.The technology also displayed operational limitations in its ability to generate and maintain the required level of nitrogen purity necessary to provide insect control(99%).In comparison,the generation of nitrogen using membrane technology cost$0.99 per tonne of grain.Other performance gains were generation of required nitrogen purity within 4.5 days of operation and ability to maintain purity for the required 14 days to provide full control of pests.
