cracking furnace

Nonetheless, a steam cracking furnace can usually only run for a few months at a time between de-cokings.

In modern cracking furnaces, the residence time is reduced to milliseconds to improve yield, resulting in gas velocities up to the speed of sound.

Cracking furnaces and downstream hydrocarbon separation units are designed to accommodate a wide range of throughputs and product mixes.

A Visbreaking Unit, consisting of a cracking furnace and atmospheric and vacuum distillation towers, was brought onstream in late 1991.

He was president and later chairman of the Alcorn Combustion Company in Manhattan, a designer and manufacturer of cracking furnaces and incinerators.

Heavier feedstocks, such as naphtha and gas oils require at least two "quench towers" downstream of the cracking furnaces to recirculate pyrolysis-derived gasoline and process water.

In March, 2011, Wison Engineering, a subsidiary of Wison Group, finished construction on the world's largest single production capacity of an ethylene cracking furnace.

Meanwhile, maintenance works will continue for two cracking furnaces of the second ethylene unit at its Maoming refinery that had been under repairs due to a fire last month, it said.

Also, ethylene plants generate hydrogen as a co-product from cracking furnaces in making ethylene and other chemicals (e.g. propylene, butadiene). This hydrogen stream can be used at the nearby ammonia plants as well (Cheminfo Services, 2006).

The Company has developed various proprietary technologies, including HS-I, HS-II and HS-III cracking furnace proprietary technologies, certain MTO light olefins separation technologies and WMTO process technologies.
