Sulfur Monitoring Articles

  • Analysers and next generation SRU control

    The history of on-line process analytics is a relatively short one. Development was driven by the need for process control of high value hydrocarbonbased products. The first on-line analyser applications came during the second war. Rapid development came in the 1970s with the advent of the microprocessor and resultant chemometric techniques. Led by Phillips Petroleum, Union Carbide and Dupont ...

  • Failure analysis showing the effect of sulphur content in stainless steel on the resistance to stress corrosion cracking in marine environments at ambient temperatures

    The risk of environmentally assisted cracking in downhole components is high due to sour conditions, i.e. the presence of hydrogen sulphide. Therefore a range of materials possessing excellent corrosion resistance are employed. However, corrosion is not only downhole related but is also a common problem on the platform deck itself due to airborne salts from ocean spray. For this reason the ...

  • Focusing on environmental pressures from long‑distance transport

    The European Environment Agency's (EEA's) annual Transport and Environment Reporting Mechanism (TERM) report presents an overview of transport demand and pressures from the sector on the environment, as well as selected related impacts and policy responses. The report makes use of the latest available data in order to assess key trends and overall progress in meeting policy targets. The 2014 TERM ...

  • The Seven Deadly Sins of Sulphur Recovery

    Introduction - The availability of information regarding the operation and optimization of Claus sulphur recovery units has increased significantly over the past years. For individuals involved in the day to day operation of the Claus unit, however, the sheer volume of information can often be overwhelming, and it is difficult to determine what is of direct importance to the plant performance. ...

  • Measurement of Sulfur in Refinery Flare Gas Streams for Compliance with EPA SubpartJ(a) Regulations

    The Challenge Measurement of high range and low range H,S in refinery flare gas streams for compliance with EPA regulation NSPS Subpart J(a). The rule has placed an extra investment and operational burden on petroleum refineries to meet the regulatory requirement. AMETEK offers an economical solution to meet the challenge with an emphasis on lower capital and operating cost along with ...

  • Can slow steaming lower cost impacts of sulphur directive – shippers’ perspective

    The International Maritime Organization (IMO) (2013, 2014) and the European Parliament (EP) (2005, 2012) have addressed the matter that harmful air emissions should be decreased in shipping transportation. The purpose of this empirical case study is to examine and anticipate in detail if slow steaming in freight shipping can bring any economically positive effects to shippers in the new fuel ...

  • NEC Directive status report 2013

    This report describes the most recent emission inventory information provided by the Member States of the European Union (EU) at the end of 2013 under Directive 2001/81/EC, the National Emission Ceilings Directive (NECD) (EC, 2001). The NECD requires all 28 EU Member States to report information annually on emissions of four significant air pollutants: nitrogen oxides (NOX), non.methane volatile ...

  • Behaviour of different cementitious material formulations in sewer networks

    Sewer networks are subjected to degradation, including biodeterioration of materials, in the presence of biogenic sulfuric acid, leading to costly repairs. To ensure durable structures, it is essential to select the best adapted materials. Two cementitious materials based on ordinary Portland cement (OPC) or calcium aluminate cement (CAC), were subjected to biodeterioration in the headspace of ...

  • Thermal dissolution of Shengli lignite in ethyl acetate

    Thermal dissolution (TD) of Shengli lignite (SL) in ethyl acetate (EA) was carried out under different conditions, including temperature, solvent to SL ratio (RS/SL), and time. The yields of EA–extractable fractions (EAEFs) increased with raising temperature from 240–300°C, but then decreased when the temperature was higher than 300°C, and the effects of RS/SL and time on EAEF yields was slight ...

  • A closer look at urban transport - TERM 2013: transport indicators tracking progress towards environmental targets in Europe

    Transport guarantees our mobility and access to goods. Moreover, the transport sector helps maintain and develop our societal and economic systems. Transport is also a main source of pressures on the environment, such as the unsustainable use of natural resources, as well as greenhouse gas, air pollutant and noise emissions. Many of these environmental problems are inter-linked, requiring ...

  • A review of thermochemical cycles for hydrogen production: analysis of potential of membrane technology in I–S, UT–3 and CuCl cycles

    Global warming and climate change necessitate a serious move away from fossil–based systems toward hydrogen economy. A study has been carried out on different thermochemical cycles for hydrogen production to bring about their important aspects. The study involves process description of different routes followed by thermochemical cycles. These include metal oxide processes, sulphur family ...
