Amine and solvent management around the world

Our vast global experience providing online amine hygiene and solvent management to the ammonia, gas, oil, and steel industry places MPR in a unique position to serve its customers. Our dedicated research and development group continues to make improvements in our technologies meeting ...


Amine headaches a pain

MPR Services understands that amine engineers face a never ending group of challenges in ensuring their systems perform as designed. Since 1989, MPR Services has been working with amine engineers in addressing these challenges through our scientifically, developed technologies. In 1990, ...


Anti-fouling trays maximize coker main fractionator profitability

The Coker Main Fractionator is systematically subjected to harsh operating conditions that can lead to deteriorating efficiency and performance due to coking and fouling. Poor reliability results in loss of profitable coking margins for the refinery. The main fractionator vapor feed from ...


Auto-switch boring / cutting tool

The innovative DeltaValve auto-switch coke cutting tool provides a high level of safety and reliability during de-coking operations by allowing the tool to remain in the drum during switching between boring/cutting modes. The auto-switch tool, in combination with the DeltaValve drill stem ...


Avoid fired heater coking

For many refiners, heater coking in Crude and Vacuum Distillation Units (CDU/VDUs) is a common occurrence. Many units around the world are shut down every two years, every year, or even every six months to deal with chronic heater coking. However, with the right design features driven ...


Avoid unnecessary costs by understanding process problems before taking action

When a piece of process equipment starts experiencing problems and producing off-spec product, every engineer’s reaction is to make a change to “fix” the problem and get it back on-spec. yet, many plants lack adequate instrumentation to completely diagnose the cause of ...


Bicine can be controlled

Bicine is a very corrosive degradation product produced in certain DEA and MDEA systems. Amine system operators must take steps to minimize O2 and SO2 incursion into the amine system and will need to monitor Heat Stable Salts and Amino Acids (Bicine) concentrations in the amine.


Cyanide corrosion causes costly upsets

Refinery cyanides cause considerable corrosion, hydrogen blistering and waste water treatment problems. The majority of refinery cyanides are formed in the reactor of fluid catalytic cracking (FCC) units. All of the gas from the reactor, including the cyanide, is carried overhead into ...


DeltaValve retractable center feed injection device

The introduction of DeltaValve’s fully automated coke drum unheading valve in 2001 necessitated the development of side feed entry into the coke drum. No longer was it possible to feed resid into the coke drum through the bottom  ange as was standard with traditional manual ...


ITW Online Cleaning

Will revolutionize turnaround operations and operational excellence by optimizing: productivity, operability, safety health and environment, reliability, product quality, energy efficiency, CO2 SOX NOX VOC emissions, maintenance and repair and operational requirements. An entire Unit can ...


Make your feeds more valuable with FLEXICOKING™ technology

FLEXICOKING™ technology is a commercially proven, cost-effective, continuous fluidized bed process that thermally converts heavy feeds to lighter products and flexigas. FLEXICOKING technology, as an integrated process, offers great flexibility when upgrading residuum, as it provides ...


Making the invisible visible

In FCC Units (Fluidised Catalyst Cracking Units) the atmospheric residue from the distillation is cracked to LPG, naptha and other components. This sometimes leads to “invisible” deposits inside the Riser. This article features Tracerco’s ThruVision™ scans to illustrate ...


Minimize recycle and coke carryover with the coker main fractionator washspray header design

Coker Main Fractionator flash zone design is critical to reliable operation of the column and maintaining product quality. This section commonly experiences problems related to the presence of unstable heavy liquid and carryover of solids. Successful operation often hinges on the design ...


Moving gamma scanning forward – quantitative analysis of tray capacity

Improving process operating margins can include maximising production of higher value products and/or minimising production costs. Process plants depend heavily on fractionation towers to produce products meeting customer specifications. Tower gamma scanning is well established in the ...


On budget, on time, offine

Flawless project execution will not prevent a unit shutdown due to selecting the wrong metallurgy for a challenging crude slate. No matter how well it is fabricated and installed, a shell and tube exchanger with cold, high viscosity vacuum resid on the tube side will have poor heat transfer ...


OptiFuel™ technology and Albemarle coker additives

Reduced coke yield and increased operating flexibility. For many years, delayed coking units have played an important role in oil refineries as one of the most cost effective processes to convert vacuum residue into more valuable products. The delayed coking yields are the result of thermal ...


PackView™ - quantitative analysis of packing mal-distribution

The last issue of Tracerco Insight (Vol 6 Ed 1) featured our patent pending FrothView™ technology illustrating how using Tracerco’s new measurement detector technology and analysis of gamma scan data provides quantitative information about the useful capacity of trayed towers. ...


Removal of foaming

In a recent case history, an East Coast Refinery was experiencing frequent upsets in their amine system due to foaming. MPR Services was contacted and brought in their SigmaPure™ System. SigmaPure removed the foaming agents and the unit returned to optimal operations. Operations ...


Running dirty amine to save costs

Some plants have saved money in the short term by running dirty amine/glycol systems. The result of this obfuscation strategy often is problematic operations. Problems resulting from corrosion, foaming and loss of acid gas absorption arise from processing with contaminated amine/glycol. ...


SigmaPure™ system

MPR Services knows no borders when it comes to helping you mitigate solvent losses and plant upsets due to foaming! Now there is a way to eliminate foaming issues without additives and gain the optimum plant performance you need. MPR has taken its SigmaPure™ Technology and redesigned ...


Tracerco Diagnostics™

Traffic jams in your amine system

Have you ever found yourself in a traffic jam – one that results in a gridlock? If you have, you probably will not forget the frustration and headache that resulted from lost time just sitting there feeling helpless. You probably felt there were just too many cars on the road. If ...


Understanding amine system terminology

As we work with valued customers in our business, we have come to realize that there is confusion with some of the terms used to describe amine systems. Some of these terms such as Heat Stable Salts, Heat Stable Amine Salts, Lean Loading, Bound Amine, etc may need clarification. We explain ...
