National oil companies are diversifying by investing in new world-scale, refinery-integrated petrochemicals. Established chemicals companies, meanwhile, are focusing on core competencies to stay competitive. All producers need to ensure their facilities are safe, compliant and built and operated to the latest technology. They also seek to avoid unplanned shutdowns, reduce energy consumption, be more sustainable and ensure the quality of both the feedstock they use as raw materials and the chemicals products they sell. Also, all this must be handled while adhering to regulations and protecting the environment. Throughout, businesses strive to maintain profitability by maximizing the reliability of existing facilities, production efficiency.
