Crucial positions require compact solutions

When Sinopec Shanghai Petrochemical Company (SPC) revamped its ethylene oxide plant in Shanghai, solutions were needed for critical heat exchanger positions within the facility’s absorption-stripping system. Size was a determining factor. For SPC, a solution from Alfa Laval requiring minimum space and offering high efficiency provided the answer for both positions.

Systems like these have two critical heat exchanger positions – the interchanger and the lean cooler. The interchanger recovers heat at the bottom of the stripper, while the lean cooler reduces the temperature of the regenerated absorption medium before re-entering the absorption tower. Both positions are extremely important to system capacity and efficiency.

Alfa Laval has sold units to EO/EG applications for over 20 years and to all the various, main processes. By using Compabloc, the benefits of an all-welded product in combination with high efficiency saves EO/EG producers money and maintenance. More than 50 Compabloc units are in use within EO/EG plants today.
