News ReleaseSyngenta Invests in ExStream™ Emissions Control Solution

July 26, 2004 Lehigh Valley, Pa.

One of the world's leading agribusinesses, Syngenta, is investing in state of the art cryogenic emissions control technology, developed by Air Products, as part of its commitment to environmental best practice.

Syngenta is a market leader in crop protection and ranks third in the high-value commercial seeds market. Like many manufacturers in the chemical and pharmaceutical industries, solvents or volatile organic compounds (VOCs) are used as part of some production processes.

Amid tightening environmental legislation, the company is investing in a new emissions control system, CryoCondap® ExStream™, to recover VOCs from process gas streams to near 100% efficiency. The compact system is capable of recovering even the most complex VOCs at low gas flow rates, below 300 Nm³/h. The system can also be easily adapted on site to recover different VOCs at varying freezing temperatures and concentrations.

Mark Northwood, Air Products' commercial manager, for cryogenic applications in the UK, said:

"Legislation is a key driver for solvent-using industries, to minimise air pollution and ensure they can meet tough emissions limits now and in the future. Our ExStream™ technology is capable of near zero efficiency at low gas flow rates and therefore represents an ideal solution."

While keeping up with changing legislation is important, Syngenta's decision to invest in cryogenic abatement technology reflects the company's commitment to enhancing sustainability and caring for the environment in the longer term.

Syngenta were impressed with Air Products' knowledge of working with difficult solvents and their ability to demonstrate the efficiency of the ExStream™ solution in laboratory trials at an early stage. In particular, they were impressed with the scope the solution allows for enhancing the sustainability of our processes, by allowing for solvent reuse.
