Consider both actual and virtual spare parts inventory

Hydrocarbon Processing Staff: Bloch, Heinz P.

Globally, hydrocarbon processing industry (HPI) facilities operate hundreds of thousands of fluid machinery assets. The various service-specific internal components of these assets are supported by ma..

Consider novel CGC and front-end depropanizer system for olefins production

Lamar University: Xu, Q.  |  Fu, J.  |  Zhao, C.

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?

Nexant: Farrell, L.  |  Virosco, J.

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

Saudi Aramco: Al-Zahrani, S.  |  Bright, E.  |  Roy, S.

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

Calabrian Corp.: Deters, B.
Emerson Process Management: Wolkart, R.

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

WorleyParsons: Khan, M. S.

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..
