Altrium®

Altrium® is the newest BASF catalyst based on the combined technologies AIM (Advanced Innovative Matrix) and IZY (Improved Zeolite-Y). Due to changes in market environment, increasing the LCO output through better bottoms upgrading became more attractive for refineries. The newest BASF resid catalyst, Altrium, was introduced to a Western European refinery to increase transportation fuels yields. Operation Background and Performance The fluid catalytic cracking unit (FCCU) ...

Caustic tower revamp

A customer contacted Sulzer to increase capacity while improving the CO2 removal in the existing CO2 absorption column of their ethylene plant. This was the third revamp for this particular column and continued improvements can be hard to find. A proper caustic tower design requires a proper understanding of CO2 absorption with caustic. CO2 + 2NaOH Na2CO3 + H2O Sulzer replaced the conventional random packing with NeXRing and modified the operating parameters to match the ...

Valve solutions for sulphur applications

How to select a valve for sulphur applications? We asked our expert Vincent Wang to answer this frequently raising question. What are the key points to address when selecting a valve for sulphur applications? When we talk about sulphur valves, in most cases they are used in the sulphur recovery unit. Various processes in refineries and gas plants produce gases that contain hydrogen sulphide (H2S) and the amount of sulphur is legislated to meet HSE and gas piping specifications, ...

Avoid fired heater coking

For many refiners, heater coking in Crude and Vacuum Distillation Units (CDU/VDUs) is a common occurrence. Many units around the world are shut down every two years, every year, or even every six months to deal with chronic heater coking. However, with the right design features driven by a solid understanding of heater coking mechanisms, fired heater run length can be extended beyond five years, even with relatively challenging crudes. The two primary drivers of heater tube ...

TRI-SHARK Control Valves

TRI-SHARK control valves are able to achieve a nearly equal percentage inherent characteristic, which greatly extends the control range ability. Furthermore, they offer great advantages in the field of cavitation reduction and noise attenuation, as well as in dynamic torque reduction. They are suitable for a wide range of services, for cryogenic temperatures from -196°C up to +815°C, including liquids, gases and steam.

When reliable operation and easy inspection is key

Topsoe’s outlet collector is easy to install and inspect and help ensure even flow distribution in the bottom of the reactor. It is important to have the best catalyst to ensure optimal performance of your hydroprocessing unit. However, it is equally important to have the best reactor internals to ensure the optimal flow conditions for the catalytic reactions in your reactor. Topsoe’s outlet collector ensures even flow distribution in the bottom bed thereby maximizing ...

MERICON™ spent caustic processing

MERICON™ technology provides an on-site solution for the processing of spent caustics to reduce their biological oxygen demand (BOD) and chemical oxygen demand (COD), control odor, adjust acidity and destroy phenolics. Merichem Company’s patented technology produces a neutral brine effluent stream that can be routed to waste-water treating facilities, evaporation ponds, or waterways. MERICON technology was first licensed in 1988. To date, Merichem has granted 30 operating ...

DuraSOx™

Highly attrition-resistant SOx reduction additive without performance compromise. DuraSOx SOx reduction additive is the culmination of intensive development work focusing on obtaining the most attrition-resistant Sox additive on the market without any performance compromises.
