CISDI has transformed site conditions and reduced emissions at Formosa Ha Tinh’s coking plant in Vietnam.

Vastly improved results have been achieved by upgrading a dust collection system and rebuilding a coke screening building.

The site now has a cleaner indoor environment for workers and is meeting all emission target indicators.

“Our working conditions have been greatly improved, thanks to CISDI’s environmental protection solutions,” a Formosa Ha Tinh spokesperson commented.

Upgrades to the dust collection system were required under FHS’s Environmental, Social and Governance Improvement programme.

The coke screening building needed to be rebuilt because the plant’s coking process had been changed from a wet quenching method to dry and had created a dustier environment.

During a lengthy design process, CISDI engineers visited the Vietnamese site on multiple occasions, carrying out numerous investigations in order to fully understand the complex interfaces between design disciplines, the complicated equipment and the building's internal structure.

CISDI recommended the replacement of the original plate-type dust collector with a dry bag filter system.

The team defined appropriate air volumes and optimised the necessary dust collection points and pipelines.

To counteract the fact that site space was limited, CISDI installed new facilities on elevated structures.

Despite challenges posed by stormy weather, cramped site spaces and the Lunar New Year holiday period, CISDI’s team completed construction ahead of schedule by painstakingly organising all design, supply and installation work.
