The C<sub>3</sub> splitter in an olefins plant is one of the most important and critical pieces of equipment: it separates polymer-grade propylene from propane.

FCC and HDS feed flexibility and integration with the delayed coker in the Izmit refinery
Tüpraş: Kantar, B. O.  |  Tunca, O.  |  Azizoğlu, Z.  |  Önen, M. F.  |  Genç, M.

Operational flexibility is one of the key parameters that leads to success and sustainability in refinery production.

Select adsorbents for a heat regenerated compressed air dryer: Competitive advantages
BASF: Vityuk, A.

Compressed air is an important utility in refining and chemical industries and is widely used to drive pneumatic equipment and machinery.

Critical considerations for retrofit designing a platformer reactor’s partial bypass piping in a NHT plant
Saudi Aramco: Kittur, A.

The naphtha hydrotreater/continuous catalyst regeneration (NHT/CCR) platformer produces reformate to be utilized as a blending stock in the gasoline pool (FIG. 1).

Complete hydroconversion of crude oil to light hydrocarbons
Contributing Author: Patron, L.

One of the prevailing factors of the energy transition toward a low-carbon energy system is that the decarbonization of transport will lead to the contraction of the main markets in which crude oil refining products are sold.

Environment and Safety

Risk identification and management
Contributing Writer: Anwer, A.

Operations within the hydrocarbon industry involve numerous hazards to be identified, mitigated and maintained at as low a level as reasonably practicable.

LNG

Boil-off gas APC exceeds expectations
Greenfern Dynamics: Taylor, A.  |  Pierterse, F.
ConocoPhillips Australia: Wilson, T.  |  Davis, R.

The use of advanced process control (APC) technology on LNG liquefaction trains is well accepted with some of the earliest implementations developed in the late 1990s.

Valves, Pumps and Turbomachinery

Added benefits of control-valve environmental packing
Emerson: McMahon, T.

Packing selection used to be a straightforward task that played a small part in a valve specification process that was much more involved.
