The Houston session will focus on how architecture plays a role in managing operational performance. Eastman Chemicals (Longview, TX) and PDC Corp are interested in presenting an overview of Eastman’s architecture and its role in assuring regulatory compliance across Eastman’s manufacturing complex located in Longview, TX. It relies on three primary “pillars:” (1) PI, (2) Oracle, and (3) the COMPASS (Compliance Assurance System) from PDC Corp. Through this integrated approach, Eastman captures timely updates to compliance-driven activities more than 8,000 times each day, ranging from production rates entered through PI hand-held computers, to firebox temperatures, flow rates, and other data recorded in PI tags. Each of these data points is tied into a hierarchy of secondary compliance tasks with embedded links to regulations and permit requirements that expand to nearly 50,000 discrete compliance demonstrations. The entire network of compliance activities is monitored closely and actively to ensure consistency with the most recently published regulations and permits. OSIsoft’s Houston technical staff were involved and supported PDC during all phases of development.
