Maximize LPG recovery from fuel gas using a dividing wall column
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.
Optimize amine sweetening with an optical O2 analyzer
After extraction, raw natural gas must go through processing before it is suitable for industrial, commercial and residential usage. The first stage of gas processing is known as “sweetening,..
DCS migration: Lessons learned
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
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..
Use a schedule confidence tool to manage project risk
On most industrial projects, the baseline schedule completion date and the indicated schedule completion date are typically the same, unless the schedule is forcibly re-baselined. Key learnings have indicated that a reevaluation of the scope, schedule and budget is essential.
Fine-tune monitoring of critical compressors
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
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
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
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..
