Petroleum Refining
As an advanced process control company, we believe that one of our strongest assets is our background in heavy industry. We employ engineers that are experienced in these industries and have degrees that facilitate process understanding. We have been working in refineries for over 20 years and have implemented regulatory and advanced controls on an array of process types. While all refineries have similarities, each refinery has unique needs. By combining holistic process understanding with an artistic eye for optimization opportunities, APCO engineers will work with your engineers and operators to make your refinery operate as safely and efficiently as possible. We love solving difficult control problems. Give us a try.
