Scrubber Engineering Project

A fast track project with no preliminary engineering work done Project Summary

Sigma had partnered with a local client to install new air scrubbers on their Urea Granulation Trains to reduce air emissions.  This project was a fast track project with no preliminary engineering work done.   We are engineering the installations of the new scrubbers, stacks, and fans.  The new scrubbers will be installed while the unit is in production. Each granulation train will be tied into the new scrubber one at a time.  There is also a challenge of fitting large ducting into extremely tight spaces in the existing units. Currently project is on time and on budget.
