In spite of the fact that anhydrous ammonia is classified as a highly hazardous chemical, it continues to be the preferred refrigerant for industrial refrigeration users. Ammonia systems offer high-energy efficiency, low capital cost, and simplicity that other systems simply cannot match. This paper summarizes Tropicana’s approach to addressing possible safety concerns with their large refrigeration systems, by developing and implementing “World-Class” standards, and upgrading existing plant facilities. The largest single undertaking in this process was the building of a 14,000-ton compressor room in Bradenton, Florida, to replace a large and antiquated central machine room. This complex and difficult project required a thorough consideration of refrigeration design principles and serves as the major backdrop for the following discussion. It is hoped that others can learn from this juice processor’s experience in search of “World-Class” standards for safety, reliability, and efficiency of their refrigeration systems. Enhancing the safety of a plant’s ammonia systems should be a common goal for all processors in our industry. Paper published with permission.

Abstract:: Activated peroxide systems are formed by adding so-called bleach activators to aqueous solution of hydrogen peroxide, developed in the seventies of the last century for use in domestic laundry for their high energy efficiency and introduced at the beginning of the 21st century to the textile industry as an approach toward overcoming the extensive energy consumption in bleaching. In activated peroxide systems, bleach activators undergo perhydrolysis to generate more kinetically active peracids that enable bleaching under milder conditions while hydrolysis of bleach activators and decomposition of peracids may occur as side reactions to weaken the bleaching efficiency. This mini-review aims to summarize these competitive reactions in activated peroxide systems and their influence on bleaching performance.
