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.

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.

Olefins, also known as alkenes, are unsaturated hydrocarbons, use to make many petrochemical products such as plastics. Olefin production, including ethylene, propylene and butadiene products, requires tight control for higher throughput, more energy efficient, and more reliable operations. In an article from The Chemical Engineer, Increasing Ethylene Conversion and Plant Reliability, Emerson’s Blake Coleman describes […]

For a valve, zero leakage is defined as no visible leakage when tested at high pressure with water and low pressure with air according to existing international standards. Some of these seat leakage standards for control and isolation valves include ANSI/FCI 70-2/IEC 60534-4, API 598, MSS SP-61 and ISO 5208. ANSI/FCI 70-2 and IEC 60534-4. […]

For manufacturers with energy intensive processes, such as the petrochemical industry, the shale oil and gas boom in North America has led to lower feedstock costs. In this short, 1:34 video, Emerson’s James Beall describes some of the challenges faced by plants to more efficiently operate their ethylene furnaces. For those unfamiliar with the ethylene […]
