Global Experts attending the Two day workshop on ‘Sulphur Recovery ‘ here today stressed on the need of implementing strict emission controls including heavy reduction of sulphur content in various fuels including diesel and coal to avoid harsh environmental consequences similar to one faced by National Capital Delhi recently .
“World Wide efforts are on to strive towards minimizing impact on the environment by implementing strict emission controls including reducing sulphur content in various fuels including diesel, but India is yet to adopt emission controls as adopted by various countries including China globally, in fact India is moving towards becoming world’s top sulphur Dioxide emitter” said Mr Yatinder Pal Singh Suri, Chairman, Process Plant and Machinery Association of India (PPMAI) the apex capital goods producers body which organised the Two day workshop and Managing Director , Outokumpu India .
“The Sulphur Recovery Unit (SRU) is an extremely important unit in the Refinery, power plant or Gas Plant. They help in reducing Sulphur content and emissions in diesel and other fuels. Without it, there would be harsh adverse environmental consequences including severe acid rain, as well as lethal ground level SO2 toxicity. Environment regulatory bodies in most of the countries have strict implementation norms to recover and reduce sulphur content” according to a Sulphur expert, from Canada
“ The regulatory bodies in various countries including India have to impose higher minimum overall recovery efficiencies from the Sulphur Recovery units Not only do the day-to-day SRU operations need to include optimization and reliability to meet these recovery efficiencies, even guidelines during upset conditions (including flaring) are becoming much more stringent. The bottom line is that the SRU must be both reliable and able to achieve the minimum. This will help in improving air quality” said Mr Jochen Geiger of Ametek Process Instruments , Europe and Middle East .
The sulphur recovery requirements in various countries differ as Canada increase from 98.5% for plants with a capacity of 50 tpd up to 99% for plants with a capacity of 2,000 tpd. In South America, the sulphur recovery requirements vary from 99.0% to 99.9%, depending on where the plant is located. The European countries are required to reduce the maximum levels of sulphur in diesel and gasoline by environmental regulation agencies. However, the overall sulphur recovery in most European countries is at least 98.5%. Germany requires sulphur recoveries of 99.5% for plants with a high capacity and 99.8% for plants with lower capacity. In India it is 99 % for higher capacity plants .
Sulphur is the primary source to produce sulphuric acid, the world’s most used chemical and a versatile mineral acid used as an essential intermediate in many processes in the chemical and manufacturing industries. Sulphuric acid is used by the fertilizer industry to manufacture primarily phosphates, and also nitrogen, potassium, and sulphate fertilizers. Sulphur is also used in many other industries including non-ferrous metals, pigments, fibers, hydrofluoric acid, carbon disulphide, pharmaceuticals, agricultural pesticides, personal care products, cosmetics, synthetic rubber vulcanization, water treatment, and steel pickling.
