Title: Gas savings of 60 million scf/yr realized with computerized system

Abstract

American Cyanamid Company decided to take a different approach to control and monitor its Fortier ammonia plant process in Avondale, LA. While others chose packaged systems, the company opted to personally design the installation, buy a general-purpose minicomputer, and then integrate all of the peripherals. The 2 1/2-year-old plant was designed with pneumatic controls and had no provisions for computer interfacing. Although it was more costly to interface the pneumatics and electronics, the company determined that the savings would quickly exceed the purchase and installation costs. The expected payback for systems such as this is ordinarily about two to three years. The system, which went into operation in midsummer 1980, is providing the desired results. These include greater efficiency through process stabilization and furnace firing control, time-saving of engineers and technicians, and the versatility that permits control strategy changes when there are process changes. System monitors more than 500 points of pressure, temperature, flow, and analyzer data in the 750-tons/day plant. Approximately 40% of the points are for temperature. It is expectecd to pay for itself through fuel savings and increased production in about 18 months.
