Fluoropolymer Linings Facilitate Leak-free Distribution of Aggressive Media

Posted on 27 January, 2010 | Tags: Case Study

Magnetic drive pumps from Richter Chemie-Technik GmbH, lined with DuPont™ Teflon® PFA and PTFE, have been in operation at Chemada for more than fifteen years. They are used for the reliable and leak-free distribution of aggressive and highly toxic media containing bromide.

Case HistoryThe Israeli chemical company Chemada uses MNK-B magnetic drive pumps from Richter Chemie-Technik GmbH for the distribution of highly reactive and toxic media containing bromide. All parts of the pumps which come into direct contact with the media are lined with either DuPont™ Teflon® PFA or Teflon® PTFE. These fluoropolymers demonstrate excellent resistance to a number of chemicals, as well suitability for use at temperatures of 200 °C in pumps. Such properties mean that the materials make a significant contribution to the reliable and leak-free performance of the pumps, thus rendering unforeseen pump failures a thing of the past.Previously Chemada had used pumps with mechanical seal rings. However, such designs with mechanical seal rings require a high level of supervision and maintenance, which increases when used with aggressive media containing bromide. For this reason, Chemada chose to use the sealless magnetic drive pumps from Richter Chemie-Technik. A wise decision, since confirmed by over fifteen years of service at Chemada without any unplanned pump downtimes and thus considerable savings for the company. Richter Chemie-Technik coats the housing, impeller and rotor of its magnetic drive pumps with a thick layer of Teflon® PFA, which is processable as a thermoplastic. The

Facilitating Net Zero Environmental Impact

Posted on 27 January, 2010 | Tags: Sustainable Practices

At Rockwell Automation sustainability is serious business and the company has made strides in the field of providing sustainable solutions for multitude of industries since the time when this word was a vogue. Som Chakraborti, Business Director, Process Automation along with John Watts Manager Process Solutions, Asia Pacific discuss the key role PlantPAX system, offered by Rockwell would help the industry to adopt sustainable practices to tackle the issues chemical industry is grappling with.

Even when the industry had not progressed to meet the challenges in terms of diminishing energy resources, water scarcity and emissions, sustainability appeared as a buzzword in the industry circles repeatedly. Owing to rising energy and raw material costs, this buzzword driven earlier by regulations is now an imperative.Definition of sustainability has gone beyond the impact on environment and having green energy efficiency program. It is an operational matrix where all the people and organization is accountable for the progress of the initiative towards mitigation of overall negative impact on the environment. The initiative should encompass variety of areas from environment to energy optimization, plant and personnel safety." Sustainability is not something that needs to be limited only to a company's annual report," says Som Chakraborti, Business Director, Process Automation, Rockwell Automation. However, increasing awareness and customer's responsibility would affect the industry by large and compel the businesses to develop innovative approach towards sustainability. Energy management, solvent recovery, optimum use of raw materials and recycling are some of the prevailing issues pertaining to the global manufacturing industry. "Though a company may be successful in reducing its energy bills, but usage of fossil fuels for energy generation will still leave

Innovative Approach for Increasing Petroleum Refinery Margins

Posted on 25 January, 2010 | Tags: Fluid Catalytic Cracking, Refinery Margins, Value Addition

Integration of solvent extraction unit of lube refinery and FCC unit of fuel refinery provides a unique concept of converting fuel oil components into premium refinery products, leading to significant increase in GRM

Indian Institute of Petroleum (IIP) is a centre of excellence for development of cutting edge 'solvent extraction' based technologies successfully operating in a number of Indian petroleum refineries. Recently, IIP conceptualized an innovative approach to integrate solvent extraction unit of lube refinery and FCC unit of fuel refinery, a unique concept that demonstrates zero fuel oil production from FCC unit and enhanced refinery margins. To develop this technology, IIP carried out a systematic and in-depth science based study which   included detailed physico-chemical characterization of clarified oil, design of liquid-liquid extraction runs in terms of temperature, solvent-to-feed ratios, water dosage in solvent, temperature gradient in continuous extraction column, interface position, interpretation of lab data, optimization of process conditions to achieve products (raffinate and extract) of desired quality etc. The lab study concluded that there is tremendous potential to produce premium value products such as good quality feed stocks for Fluid Catalytic Cracking (FCC) and premium grade Carbon Black Feed Stock (CBFS) from fuel oil components (clarified oil) through solvent extraction. The study also established the optimum process conditions. This technology has since then been successfully commercialized at HPCL Mahul Refinery in Mumbai which is reaping the benefits of producing additional

Prakash Steelage : the Name Synonymous with Steel

Posted on 25 January, 2010 | Tags:

When the steel industry in India was in its nascent stages, Prakash Kanugo, Chairman and Managing Director, Prakash Steelage envisioned Stainless Steel (SS) emerge as the material of millennium and set his foot into the business in 1976. He glances at the yesteryears of his journey from a trader to India's leading SS pipe manufacturers in an exclusive interview with Chemical Engineering World

  "Stainless steel is recognized as the material of the millennium, which is not an exaggeration," comments Prakash Kanugo, sitting comfortably in his swish office. He is a great visionary who envisaged the idea of getting into the business of steel trading when Indian industry was emerging and started off a company Prakash Steel in 1976. "We ventured into the business of trading of stainless steel coils, plates and strips that were sourced material from leading Indian manufacturers and also imported to supply in the domestic sector," he states. From the initial years, Prakash Kanugo has spearheaded the company's growth and has diversified its operations and has emerged as one of the leading manufacturers and suppliers of stainless steel pipes, pipes and tubes. Having gained significant experience in the field of supplying products in the domestic market, the group set up its first facility in Silvasa in Gujarat to manufacture seamless and welded pipes and tubes.  "Strategically this place suited us for its close proximity to Mumbai, easy access to the steel markets and industry friendly environment Gujarat offers," states Kanugo. "However, primary years were challenging," he reminisces.  "This was the time of globalization, there was an increase in

Market Analysis of Indian Refining Sector

Posted on 21 January, 2010 | Tags: Panorama

Oil is the world's most important source of energy. The demand for petroleum products is linked directly to the country's economic activity, which is measured by its GDP. The largest demand for petroleum products is from Asia and Asia Pacific region with strong growth in consumption shown by countries like China and India.

In 2007, oil met 38 percent of global traded energy demand, while its nearest rivals, coal and natural gas, met only 28 percent and 24 percent of global traded energy demand, respectively. The total oil consumption has increased from approximately 46 million barrels per day in 1970 to about 84.4 million barrels per day till September 2009. The high volatility in crude oil prices has been a serious concern for the economies like India who mainly import crude oil. The volatility in process can be seen from the graph below The largest demand for petroleum products is from Asia and Asia Pacific region with strong growth in consumption shown by countries like China and India. In the past, higher population of India and China proved to be a stumbling block for its development. Today the same population with higher per capita income is proving to be a major growth catalyst. In case China and India, which together account for approx 35 percent of world's population, were to consume on per capita basis, at the same level of oil as that of Brazil, (only 4.2 percent of world population), global oil consumption shall reach a whopping 102 million barrels a
