A proven design eliminated control interactions in this ethylene cracker facility
An investment was made in a project implementing an advanced recovery system to increase throughput and thermal efficiency of an ethylene cracker facility. Design changes were required in the compressor control and safeguarding philosophy. This article discusses these design changes and their implementation. Although during the project the control and safeguarding systems of the ethylene and propylene refrigerant compressors were also revamped, this article focuses on the cracked gas compressor.
In this facility, naphtha is thermally cracked in furnaces at atmospheric pressures after which the cracked gas is quenched, prefractionated, compressed, scrubbed with caustic to remove acid ga
