If no action is taken to upgrade theseexisting units, there will be a high frequency of equipment failure, an excessive number ofshutdowns and slowdowns and attendant high maintenance cost. There will also continue to bethe need to burn excess H 2 S which will result in the release of SO 2 . Therefore, residents willcontinue to experience the adverse conditions associated with gaseous releases.EcoengineeringxiiiEnvironmentally appropriatedevelopment for the Caribbean
