Consider novel CGC and front-end depropanizer system for olefins production
In the presented case study, an innovative design for an integrated CGC-DeC3 system introduces part of the heavier condensate from the early compression stages directly into the high-pressure (HP) depropanizer.
North American olefin producers riding the shale gas wave
With the prospect of abundant low-cost ethane, several producers have announced intentions to build new ethylene capacity.
High-pressure polyethylene: Reemergence as a specialty chemical or not?
The analysis results indicate that, while investment capital for new plants favors LLDPE, plant profitability—which is a function of product slate (revenue) and cost—is, in many cases, higher for LDPE plants.
Evaluate challenges in meeting clean-fuel specifications with heavier crude
At a Saudi Aramco refinery, a revamp was planned for processing a different crude oil blend to meet Euro 5 diesel and gasoline specifications. The refinery, which processes semi-light crude oil, is sc..
Improve coker efficiency with reliable valve automation
The case history discusses conditions occurring in delayed coker operations at two refineries in Louisiana, the impacts on valve performance, and a solution that offers extended life, better reliability and other benefits.
Take a quicker approach to staggered blowdown
The design of a reliable blowdown system for a large sour gas-processing facility is one of the most important aspects of plant design. Safe design is vital for facility operation. With the developmen..
