The cold section of an ethylene plant is responsible for cooling and purifying the product-grade ethylene, propylene and other bi-products from the cracking furnaces. Cracked gas is cooled in transfer-line exchangers which produce steam from the effluent gas energy. Gas is further cooled with water in the quench column, scrubbed and dried before being compressed in the cracked gas compressor and fed to the cold box.

An ethylene plant has a number of very large, very critical compressors which will cause the entire plant to shutdown if they ever trip. The cracked gas compressor increases the entire cold-side feed from around 3 psig to ~475 psig, typically through 5 stages. The two refrigeration compressors are the next biggest compressors that can also shut down the entire plant if they trip.

According to the United States Energy Information Administration, the Texas and Louisiana Gulf Coast refiners and petrochemical producers accounted for 50.5% of the U.S. total finished petroleum products as of October 2019. So with over half of America’s refining and petrochemical production, running these facilities as safely, efficiently and reliably as possible is critical. For […]

Author: Pete Sharpe Cracking furnaces are one of the most crucial parts of an ethylene complex. They set the production and yield for the entire plant. For furnace-limited plants, when a furnace is down, whether for maintenance or decoking, production is lost. Poor control and sub-optimal furnace operations lead to lower yields, more frequent decoke […]

Authors: Pete Sharpe and Marcelo Carugo Digital Transformation is a buzz word that seems to be on everyone’s mind and lips these days. Most companies have one or more digitalization initiatives underway as demonstrated in this survey conducted at the 2019 Emerson Exchange during the Chemical Industry Forum session. Companies are already spending money on […]
