Maximize LPG recovery from fuel gas using a dividing wall column

GTC Technology US, LLC: Gentry, J. C.  |  Bhargava, M.  |  Nelson, C.  |  Siddamshetti, V.

Refiners are challenged to recover LPG from mixed fuel gas streams due to the difficulty of separating the lighter components from bulk gas. To maintain profitability, it is essential to direct all of the crude oil components to the optimum disposition. This practice is becoming more significant due to increasing LPG demand in some countries and the supply of lighter crudes in countries such as the US.

Shale gas drives new opportunities for US downstream

This shift to lighter feeds for the SC will reduce the future availability of other petrochemical feedstocks—in particular, propylene.

DCS migration: Lessons learned

TOTAL Port Arthur refinery: Conley, R.

In 2005, TOTAL’s Port Arthur refinery (PAR), like many present-day refining and petrochemical facilities, found itself with an obsolete, at-capacity distributed control system (DCS). As shown in ..

Avoid counterproductive project management practices

Hydrocarbon Processing Staff: Bloch, Heinz P.

For many years, reliability-focused engineers have observed flawed procurement processes for mechanical equipment. Many requirements are supposedly aimed at the lowest possible lifecycle cost; however..

Fine-tune monitoring of critical compressors

PROGNOST Systems GmbH: Loeken, J.

In this case history, a new monitoring system was installed on a critical service hyper compressor for a Middle East (ME) ethylene complex. This unit supported two 400 Mton polyethylene (PE) units; do..

Consider technology to reduce compressor vibration and noise problems

Dresser-Rand: Liu, Z.

Industrial centrifugal compressors installed in hydrocarbon processing industry (HPI) complexes absorb significant amounts of mechanical power when compressing gases. A small part of the mechanical en..

Achieve successful compressor startup by addressing dry-gas seal failure

Toyo Engineering Canada Ltd.: Zardynezhad, S.

A common root cause for compressor failure during first startup is a failure of the dry-gas seal (DGS) system. To avoid failures of gas compressors, the project team and end users must understand the importance and significance of the DGS very early in the basic design phase.

Without reliability, there can be no safety

Oil Industry Safety Directorate: Dutta, H.

Reliability and safety are complimentary concepts. For instance, unless process reliability at a plant is extraordinary, safety cannot be assured. Achieving the highest level of safety at a processing..

HP Reliability: Plan now to deal with stressed equipment later

Hydrocarbon Processing Staff: Bloch, Heinz P.

The US Energy Information Administration’s (EIA’s) “Today in Energy” brief evaluated how US refineries are processing record amounts of crude oil (Fig. 1), with Midwest and Gulf Co..

HP Automation Strategies: Control on the wire(less)

ARC Advisory Group: Gupta, M. S.

Since the industrial revolution, process/industrial control had relied on tightly coupled systems to transmit control signals. Industrial plants have used “modern” control via wired electron..
