Dow Announces Agreement for regeneration of Valls chemical heat transfer fluids

Dow Poliglicoles, surfactants and fluids (PS & F), a business unit of the dow chemical company (Dow), has announced an agreement with Valls chemistry for the provision of services of regeneration of Dowtherm A heat transfer fluid in Spain. Under that agreement, announced during the 4th International Summit of concentration Solar thermoelectric, held from 15 to 17 November in Seville, Valls chemistry will provide Dow of concentration Solar thermoelectric plants sector customers a service of handling and appropriate and effective regeneration in costs for the fluid Dowtherm a. Valls chemistryin collaboration with its subsidiary Speichim Processing, it will regenerate Dowtherm A to obtain a fluid heat transfer which meets the specifications of quality of Dow and is equivalent to the original product.

The regeneration of the fluid is a critical need in respect of plants of concentration Solar thermoelectric, in which each plant uses large amounts of heat transfer fluid. While the Dowtherm A fluid characterized by their high thermal stability and long service life, eventually it will be necessary to change the fluid to keep the maximum heat transfer efficiency in CSP systems. Through the agreement with Valls chemistry for the regeneration of the fluid, Dow claims that the operators of plants Termoeléctricas may limit the requirements and costs of eliminating waste of it, contributing at the same time to minimize their cost of replacement.

"As we move forward in the development of degrees of fluid transfer of heat for CSP applications, this collaboration with Valls chemistry allows us to offer an excellent service to our customers at the same time we are still betting on a constant improvement in sustainability", said Renaud Jourdan, product manager for poliglicoles, surfactants and fluids of Dow. The director-general of Valls chemistry, Luis Manent, stated that his company is "proud of having been designated strategic supplier of Dow in CSP sector." "This agreement encourages our human and technical team to continue providing the best solutions for the needs of our customers."
