COAL GASIFICATION PROJECTS – RECENT DEVELOPMENTS
Coal gasification essentially works by putting either coal, petroleum coke (the heavy hydrocarbon residue left after crude oil has been cracked) or biomass in a gasifier. Water and oxygen or air are added at high pressures (up to 1,200 pounds per square inch) and temperatures of up to 1,427 deg.C to produce raw synthetic gas (Syngas). Sulfur, carbon dioxide (CO2) and other pollutants are removed, leaving a feedstock comprising mainly hydrogen and carbon monoxide. Coal-to-liquids and coal gasification plants can be readily adapted to produce an exceptionally broad range of feedstock. This potentially provides a major competitive advantage for US industry. According to Virginia based Gasification Technologies Council, global gasification capacity is projected to grow by 70% by 2015, with about 80% of growth in the Asia-Pacific region.As feedstock costs have increased and concerns over security of feedstock supply are frequently raised, the use of coal as a feedstock is likely to increase.This is already happening in China, and the same could be expected in the US and other coal-rich countries. This article discusses the following details :
  • Efforts of Foster Wheeler
  • Efforts of Eastman
  • Coal based power projects in USA
  • RTI – Eastman process
UTILISATION OF CARBON DIOXIDE
To reduce the impact of carbon dioxide emissions on environment, carbon capture and storage (CCS) is becoming a focus subject for both scientific and industrial experts. Presently, CCS is involved in expensive cost. The carbon dioxide utilization is expected to make benefit, at least offsetting part of the cost incurred from the emission reduction. This article contains the following details :
  • Captured and concentrated carbon dioxide can be used in enhanced oil recovery (EOR)
  • Use of carbon dioxide in enhanced coal bed methane (ECBM)
  • Chemical use of carbon dioxide
  • Carbon dioxide recovery unit in Australia
TRENDS AND HAPPENINGS IN INDIAN CHEMICAL INDUSTRY
CASE STUDY OF SELECTED CHEMICALS
POLYVINYL ALCOHOL
Appearance Dry solid. Commercially available in granular or powder form CAS No. 9002-89-5 Molecular Formula [ -CH2CHOH- ]n Specific gravity 1.19 to 1.31 pH                                                      Aqueous solution is neutral or slightly acid Stability Stable under ordinary conditions of use and storage Biodegradable PVA is a biodegradable, water-soluble synthetic polymer. The degradation
products are water and carbon dioxide.
Grades Polyvinyl alcohol is one of the few high molecular weight commercial polymers. PVA is produced in four molecular weight ranges. Viscosity grade Nominal Mn 4% solution viscosity mPa.s(=cP)@ Low 25,000 5 to 7 Intermediate 40,000 13 to 16 Medium 60,000 28 to 32 High 100,000 55 to 65 @ Measured at 20 Deg C with Brookfield viscometer.
