Four-Stage Hydrocracking Pretreatment

Four-Stage Hydrocracking Pretreatment

A four-zone approach to hydrocracking pretreatment catalysis aims for greater flexibility in activity, stability, hydrogen consumption and pressure drop.

In the current market that rewards distillate production, many refiners are looking closely at the performance of their hydrocrackers. To improve hydrocracking margins, refineries explore solutions ranging from increasing feed severity to improving yield structure and product quality. Multiple operational constraints, in particular cycle length and hydrogen availability, often determine the feasibility of each approach......

Refining India 2017

Refining India 2017

Growth in India’s demand for oil products will outstrip the rest of the world during the next 25 years, according to a recent focus report from the International Energy Agency. In response, India’s government concedes that even faster growth in refining capacity is essential to keep pace with domestic demand. This will mean more and bigger refineries, integrated with petrochemicals production and geared to the highest international standards of clean fuels to combat urban pollution......

SweetSulf™ The High Pressure Redox Desulfurization Process

SweetSulf™ The High Pressure Redox Desulfurization Process

Reaction: Sour gas is contacted with an aqueous redox solution which extracts the H2S and converts it into solid elemental sulphur. Gas separation: Treated gas, free of H2S, is separated from the redox solution. Solid separation: Solid sulphur is filtered under pressure on a cartridge filter which can be regenerated on stream. Re-Oxidation: The redox solution is depressurized and re-oxidized by contact with air......
