Expert Understanding of Ethylene Systems Pre-Commissioning Cleaning

January 03, 2019 by Chris Oakley0

Expert-level understanding of the many complex systems prevalent in the petrochemical industry plays a crucial role in the work we do at B&W Energy Services. Ethylene systems are just one example of an area in which our teams stand out among the rest.

The production of ethylene and propylene through olefin manufacturing constitutes the third largest portion of the petrochemical industry, closely following ammonia manufacturing and petroleum refining. Annual global production of ethylene totals out at about 120 million tons, with a continuous increase of anywhere between 4-5 percent annually.

ENGINEERING AN EFFECTIVE CHEMICAL CLEANING PROGRAM

Ethylene and other olefins are created by the thermal cracking of gaseous feedstock, occurring in the radiant coils of a pyrolysis furnace where gas flows at a low pressure in high temperatures. The olefins are chemically unstable at these temperatures, so the highly reactive cracked gas is cooled rapidly – all of this happens within a very short interval of milliseconds.

This is where knowledge and understanding become critical for planning the pre-commissioning cleaning of new ethylene furnaces. Typically, there are many sections to an ethylene furnace. It is important to understand and navigate the flow paths for effective cleaning of these unique multi-segmented systems.

Furnaces have unique requirements for any chemical cleaning or commissioning process. Therefore, a full understanding of each furnace design becomes critical in the engineering of effective pre-operational chemical cleaning concepts. Understanding the furnace vendor’s cleaning specifications in addition to the flow characteristics for each furnace (and the corresponding metallurgy) will allow for proper determination and discussions. It is imperative to have a full understanding of the chemistries required to properly design flow paths for critically-timed events.

Considering the complicated workflows involved in chemical cleaning, you need to have full confidence in your cleaning vendor. B&W Energy Services offers years of experience combined with a track record of success, guaranteeing we will get the job done right and on time.
