  • the production of fuel oil and Combustible Gas by catalytic pyrolysis of waste tire using waste heat of blast furnace slag
    Energy Conversion and Management, 2017
    Co-Authors: Yu Feng
    Abstract:

    Abstract In this study, a novel “waste energy recycling” strategy is presented, i.e., the sensible heat of blast-furnace (BF) slag is utilized for the production of fuel oil and Combustible Gas from the pyrolysis of waste tire. The effects of various operating parameters including the slag temperature, the mass ratio of BF slag to tire (B/T) and feedstock size on yields and characteristics of pyrolysis products were systematically studied. The results showed that the presence of BF slag greatly improved the production of derived-oil and increased the contents of H2 and CO in pyrolysis Gases. This can be explained by the catalytic activity of BF slag and the CaO-MgO complex in BF slag can prevent the formation of stable chemical structures in hydrocarbons, speed up the degradation of hydrocarbons, weaken C C and C H bonds and make them dissociate more easily, and thereby decrease the activation energy of degradation reactions. Increasing BF slag temperature and B/T ratio, and decreasing feedstock (including both BF slag and tire powder) size favored the heat and mass transfer during pyrolysis process and therefore afforded more liquid and Gaseous products. In addition, it was observed that the presence of BF slag decreased viscosity, density, H and O content and increased C content, C/H ratio and calorific value of derived-oil relative to pyrolysis oil derived from solely tire powder, thereby resulting in upgradation of oil quality.

  • FedCSIS - Internet connected wireless Combustible Gas monitoring system for apartment buildings
    Proceedings of the 2017 Federated Conference on Computer Science and Information Systems, 2017
    Co-Authors: Denis Spirjakin, Alexander M. Baranov
    Abstract:

    Despite the modern Gas equipment, Combustible Gas leakage related emergency situations still take place and lead to building demolitions and human losses. Leak integrity failures because of anthropogenic and natural factors make impossible to prevent such emergency in other ways except providing continuous monitoring of Combustible Gas concentration and notification for people and special services. In this work, the design results of the Internet connected wireless sensor network for Combustible Gas concentration monitoring in apartment buildings is presented. The system consists of wireless autonomous Gas sensors, actuators, routers and a gateway and it's connected to a web service where it posts its data and gets events to react them in WSN.

    Proceedings of the 2015 Federated Conference on Computer Science and Information Systems, 2015
    Co-Authors: Denis Spirjakin, Alexander Baranov, Vladimir Sleptsov
    Abstract:

    In this work we present the results of design of smart dust sensor platform for Combustible Gas leakage monitoring. During the design process we took into account a lot of Combustible Gas sensor specific problems such as their huge power consumption, the necessity to work in explosive environment and sensor parameters degradation. To decrease power consumption we designed specific energy efficient algorithms for measurements. The resulting average power consumption of the node is low enough for one year autonomous lifetime. The methods and algorithms which was designed are very promissing for catalytic Combustible Gas sensors.

  • Test Plan for Measuring Ventilation Rates and Combustible Gas Levels in TWRS Active Catch Tanks
    2000
    Co-Authors: D.m. Nguyen
    Abstract:

    The purpose of this data collection activity is to obtain data for a screening of Combustible Gases in catch tanks that are currently operated by the River Protection Project (RPP). The results will be used to support closure of the flammable Gas unreviewed safety question for these facilities. The data collection will be conducted in accordance with the ''Tank Safety Screening Data Quality Objective'' (Dukelow et al. 1995). Combustible Gas, ammonia, and organic vapor levels in the headspace of the catch tanks will be field-measured using hand-held instruments. If a Combustible Gas level measurement in a tank exceeds an established threshold, vapor grab samples (i.e., Hoke and SUMMA) will be collected for laboratory analysis. In addition, ventilation rates of some catch tanks will be determine using the tracer Gas injection method to evaluate removal of flammable Gas by air flowing through the tanks. This test plan identifies the field tests, sample collection, laboratory analysis, quality assurance, and reporting objectives for this data collection effort. The plan also provides step-by-step direction for field measurement of Combustible Gas concentrations and determination of ventilation rates.

  • characteristics of Gaseous product from municipal solid waste Gasification with hot blast furnace slag
    Journal of Natural Gas Chemistry, 2010
    Co-Authors: Lumei Zhao, Hua Wang, Shan Qing
    Abstract:

    Abstract Possibility of Combustible Gas production from municipal solid waste (MSW) using hot blast furnace (BF) slag has been studied. The objective of this work is to generate Combustible Gas from MSW using heated BF slag. In this experiment, the thermal stability of the MSW was analyzed by thermogravimetric analysis, and effects of temperature, Gasifying agent (air, N2, steam) and BF slag on the Gas products were investigated at 600–900 °C. The thermogravimetric analysis indicates that the weight loss of MSW includes four stages: evaporation of the moisture, combustion of volatile materials, burning of carbon residue and burnout of ash. The contents of the Combustible Gas increase with increasing temperature, and the lower calorific value (LCV) increases rapidly at 600–900 °C. It is found that volume fraction of CO, H2 and CH4 at different atmospheres increases in the order N2

  • Measurement Algorithm for Determining Unknown Flammable Gas Concentration Based on Temperature Sensitivity of Catalytic Sensor
    IEEE Sensors Journal, 2019
    Co-Authors: Alexey Karelin, Alexander M. Baranov, Saba Akbari, Sergey Mironov, Elena Karpova
    Abstract:

    The assessment of the explosion hazard of a Combustible Gas mixture is not a trivial task if the type of Combustible Gases is not known precisely. Typically, the concentration of Combustible Gas is defined as the response of a catalytic sensor to its presence in the air. It has been known that catalytic sensors have different sensitivities to different Combustible Gases. Usually Gas analyzers are calibrated by methane and are not suitable for measuring other flammable Gases without additional correction for each Gas. In this paper, we have investigated the dependency of catalytic sensor sensitivity on the sensor temperature for the binary mixture of methane, propane, butane, hexane and hydrogen with air in a wide temperature range. Based on the obtained dependencies, a measurement algorithm and an empirical equation were proposed that allow calculating the concentration of unknown Combustible Gas in % of LEL. The process of measuring and processing data can be automated using a digital processor. The experimental results have shown that the concentration measurement error is in the range 5%-10% for binary mixture.
