As part of the energy assistance program to help Ukraine shut down the Chornobyl nuclear reactors, the U.S. Department of Energy (DOE) asked the Pacific Northwest National Laboratory (PNNL) to identify and appraise industrial energy efficiency projects in Ukraine. The industrial sector currently accounts for over 60% of Ukraine’s energy consumption. Most industrial enterprises in Ukraine use en...

Industrial alarm systems inform the operator of abnormal plant behavior and are required to guarantee safety, quality, and productivity of the plant. However, modern alarm systems often produce large amounts of false or nuisance alarms which leads to alarm floods. Operators receive far more alarms than they can handle. To reduce these alarm floods, we developped an alarm system that performs Ro...

A pilot-scale fluidized bed reactor was built and used to study and gain a better understanding of the propylene polymerization process at conditions similar to those of industrial fluidized-bed reactors. Propylene polymerization reaction was carried out continuously in the reactor and dynamic temperatures, and propylene and hydrogen concentrations data were collected. Simulated dynamic profile...

For the polymer production industries, the competitive edge will come from the technology that excels in controlling the polymer properties in a consistent way over the entire plant and in maximizing the production performance while keeping safety regulations. Based on the experience in applying advanced process control and scheduling schemes to industrial polyole®n polymerization plants, the s...

Designing, operating and maintaining industrial plants require extensive and complex engineering processes. An integrated engineering process considering all different aspects, data and workflow of plant automation design as well as interoperability to other systems is the key to more efficiency and lower costs of engineering tasks in the plant life cycle. There exists no comprehensive and sati...

Introduction: In order to achieve sustainable development in mining, waste management is an essential requirement. The current study aimed to examine industrial solid waste produced in Golgohar Mining and Industrial Company, which is a well-known iron ore extraction and processing complex. Materials and Methods: This cross-sectional study was conducted in two phases from March, 2016 through Ma...

The increasing use of internet in the automation field has brought new challenges in the remote control, supervision and management of industrial processes. Specifically, process data information has to be available anywhere/anytime on the internet. This brings together two main problems: process data abstraction and process data accessibility. In this paper, we present a specification for an e...

In the digital planning process of a manufacturing plant several partners like OEM, prime contractor and further service providers are participated usually. Since the partners have partially overlapping views (electricity, mechanical structure, plant controlling) on the same plant to be produced, they have to exchange data during their collaboration. However the syntactical, structural and even...

There are literally hundreds of polypeptides described in the literature which exhibit fungicide activity. Tens of them have had attempted protection by patent applications but none, as far as we are aware, have found application under real agricultural conditions. The reasons behind may be multiple where the sensitivity to the Sun UV radiation can come in first place. Here we describe a multif...
