PROCESS
IRPC Process Technologies:
An event designed to showcase
advancing technologies in the HPI
The hydrocarbon processing industry (HPI) is steadily advancing through the energy transition. New regulations and
company/governmental initiatives have and will drive the HPI
towards developing ultra-low-sulfur fuels, alternative fuels, biofuels, green petrochemicals and plastics recycling technologies.
These trends are shaping the way companies invest in new research and development programs and where capital-intensive
investments are being made in new production capacity.
However, investments in conventional refining and petrochemical processing production routes are still being made
globally. Hundreds of billions of dollars are being invested to
produce refined products and petrochemicals to satisfy increasing demand. This new capacity is utilizing the latest processing
technologies within the HPI.
These two crucial processing routes-conventional and energy transition technologies-will be instrumental in providing the fuels and petrochemical products of the future. Due to
the critical nature of these technologies, Hydrocarbon Processing
will focus on these two processing routes in its next International Refining and Petrochemical Conference (IRPC). IRPC
Process Technologies-Process Optimization and Transition
Technologies-will examine the challenges affecting the HPI,
as well as the opportunities that are emerging in new refining
and petrochemical processing technologies. The global, virtual
event will be held June 2-3 and will feature dozens of speakers
from around the world.
Agenda and tracks. The agenda for IRPC Process Technolo-

gies is now available at www.HydrocarbonProcessing.com/
Events. The event will be kicked-off with Leon de Bruyn, CEO,
Lummus Technology, who will discuss how the processing technology licensor is adapting to the current market and how it will
adapt/evolve in the future.
The event will feature two primary tracks: One on conventional refining and petrochemical processing technologies and
the other on energy transition technologies. The agenda's conventional tracks will focus on distillation, alkylation, desulfurization, ethylene and propylene production, fluid catalytic cracking,
hydrocracking, coking and refining-petrochemical integration.
The event's energy transition technologies track will focus on
alternative fuels, biofuels, green petrochemicals production, refining and petrochemicals sustainability, circular economy and
plastics recycling technologies.
