  • Process analytics in ethylene oxide and ethylene glycol plants – Case Study

    Perfect solutions from Siemens Process Analytics Ethylene Oxide (EO) Ethylene oxide, C2H4O, under normal conditions, is a colorless, flammable gas. It is very toxic and carcinogen. Industrial production started in 1925 using the chlorohydrin process and was improved in 1931 by introducing the much more economic direct catalytic oxidation method. Currently, ...

  • Process analytics in vinyl chloride monomer (VCM) plants – Case Study

    Vinyl chloride monomer (VCM), made from ethylene and chlorine by pyrolysis, is the feedstock for the production of the very common plastic material PVC. Modern VCM plants use integrated processes, combining endothermic and exothermic reactions in an almost energy balanced operation. Plants optimize the product quality, plant safety and cost efficiency by using advanced process control equipment ...

  • Process analytics in polyethylene (PE) plants – Case Study

    For the production of polyethylene a variety of processes is in use depending on what final products are intended to be produced. However, regardless of the process type, all plants require process analytical equipment to collect reliable and accurate information for process control, product quality, plant safety and environmental compliance. Siemens, a leader in process analytical ...

  • Process analytics optimizes crude gas processing for the production of fine chemicals at Lonza – Case Study

    Fine chemicals are used as active ingredients or additives in the pharmaceutical and food & beverages industries, as well as in agriculture. The cracking of raw materials such as light virgin naphtha or liquefied gas results in intermediate products (ethylene, hydrogen, methane, CO2). At the end of the process chain, these can provide highly pure materials such as niacin (vitamin B3) or ...

  • Use of process analytics in aromatics (BTX and Phenol) production plants – Case Study

    Aromatics are planar, cyclic compounds with conjugated double bonds, consisting of the elements carbon and hydrogen. Aromatics are important intermediates and used as starting materials for a wide range of products. Aromatics are derived from crude oil and, in small quantities, from coal. Process automation equipment including gas chromatographs and other process analyzers contribute essentially ...

  • Process analytics in methanol plants – Case Study

    Methanol is a clear liquid usually made from natural gas. It is a clean burning fuel, containing almost no sulphur or nitrogenous materials. It is a petrochemical that is used to make countless industrial and consumer products. In the future, methanol could be used as a source of hydrogen for fuel cells. Different concepts are in use to produce methanol looking always for higher plant efficiency ...

  • Oil and gas industry process analytics in ethylene production plants – Case Study

    Ethylene is the largest volume industrially produced organic material and its majority is used in the production of polymers and derivatives. Between a variety of processes the thermal cracking of hydrocarbons in the presence of steam (steam cracker) is mostly used. Regardless of the process type, all plants require process analytical equipment to collect reliable and accurate process data for ...

  • A GIS-based Modified DRASTIC (ANP) method for assessment of groundwater vulnerability: a case study of Nagpur city, India

    Quality of groundwater is as important as quantity. For effective planning and management of groundwater resources, groundwater vulnerability assessment is most significant. The objective of the present study was to evaluate the groundwater vulnerable zones of Nagpur city, using Modified DRASTIC methods within a Geographical Information System (GIS) environment. DRASTIC method has been ...
