New technology for heavy oil exploitation wastewater reused as boiler feedwater

Measurement of organic halogens in boiler feedwater

Materials of steam water cycles can suffer from corrosion induced by halide anions in feedwater. Organic halogen compounds in feedwater can be degraded and release halide anions under high temperature and pressure. Therefore it is necessary to be able to measure the organic halogen concentration. Existing measurements including Adsorbable Organic Halogens and Gas Chromatography are either not c...

Quality assessment of treated wastewater to be reused in agriculture

In this study, the quality of a treated wastewater for agricultural and irrigation purposes was investigated. 39 quality parameters were investigated at the entrance of an effluent channel to the destination plain in monthly time intervals during a year. The aim of this study was drawing an analogy between analyses results and the latest standards in the world (nationwide and internationally), ...

A New Mechanical Oil Sensor Technology

In view of disadvantages of commercially available oil level sensing products, this paper introduces a new mechanical type of oil sensor for refrigeration compressor’s oil level protection, which is used to avoid failure due to lack of oil in the compressor, especially when multi-compressors were connected in parallel. The paper analyzed this new mechanical oil senor in terms of superiority com...

Field Demonstration of the Activated Iron Technology for Removing Heavy Metals from Flue-Gas-Desulfurization Wastewater

The Activated Iron Process (AIP) technology, which is renamed from the hybrid zero-valent-iron (hZVI) process, is a novel chemical treatment process that has shown great potential in previous laboratory and field bench-scale tests for removing selenium, mercury, and nutrients from the flue-gas-desulfurization wastewater. In this study, a pilot-scale demonstration was conducted to continuously t...
