Air Products Installs First Cryogenic Abatement System in Singapore

Schering-Plough, the global pharmaceutical organisation, has commissioned Air Products and Chemicals Inc. to build a cryogenic solvent recovery system at its new manufacturing plant in Tuas Park, Singapore. Air Products' team of cryogenic experts has now completed installation of the Cryo-Condap(R) system, which will be used to abate volatile organic compounds from the pharmaceutical manufacturing process.

Although a first for the company in Singapore, Air Products has over 70 Cryo-Condap(R) installations worldwide catering for a range of industries including fine chemicals, pharmaceutical and refrigeration recycling. Singapore is one of the most environmentally advanced countries in Asia and stringent regulation has led companies to seek ways of meeting the strict emission controls.

The Cryo-Condap(R) system works on the basis of cryogenic condensation. It uses liquid nitrogen in a heat exchanger to cool down a waste gas stream. The solvent can then be separated from the waste gas stream and either is re-processed for use in the manufacturing process or disposed of, depending upon the characteristics of the solvents and regulatory requirements. The carrier gas is then 'virtually solvent free' and can be safely dispersed into the environment. In this process, a cocktail of up to nine different solvents are treated.

Commenting on the project, Nanna Heiberg of Air Products states, "We have the ability to recover solvents by up to 99.8% and, depending upon the application, our customer may destroy, send for processing or even reuse these solvents. This flexibility has been a prime reason for choosing Air Products' Cryo-Condap(R) technology in the past. In the case of this customer, 98% abatement will be achieved and the solvents sent for destruction."

Steve Knowles, Air Products, Engineering Lead adds, "We have worked closely with Schering-Plough to develop, build and deliver the hi-tech recovery system on budget and within a very short space of time -- ready for the anticipated mid-year opening of their new plant. Our cryogenic team is dedicated to delivering bespoke systems which provide the most efficient environmental solution to meet legislative demands now and in the future."
