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, ...


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 ...


Innovative, cost-effective crude treatment programs

We Treat Refineries, Not Symptoms. We approach every treatment challenge from three perspectives: operational, chemical and mechanical. Our technicians and scientists are supported by modern laboratories and the latest analytical tools, including portable electric desalters for emulsion-breaker ...


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 ...


Maximize reliability in grassroots crude units

Crude unit operators are far too familiar with a long list of crude unit reliability problems including fouling in heat exchangers and fired heaters, poor desalting, corrosion of piping and equipment, and coking in the vacuum column wash zone. Many millions of dollars have been spent fighting ...


NAPFINING™ Naphthenic acid removal

NAPFINING™ technologies were first licensed in 1977 and to date Merichem has granted 78 unit operating licenses world-wide. The non-dispersive FIBER FILM® Contactor achieves reduced capital expenditure and less plant space requirements compared to most treating alternatives, ...


Nasty stuff

Heavy crudes are here to stay. As longs as oil prices remain high, Canadian, Venezuelan, Deep Water Gulf of Mexico, Mexican and other low API gravity crude oils will play an ever more important role in supplying world refineries. And prices promise to remain high because gainsayers notwithstanding, ...


Oil sands crude – profits and problems?

Canadian bitumen production currently runs about 1 MMbpd, with some being sold as Synbit and Dilbit. Over the next 10-12 years output is expected to increase to 3.5 MMbpd and more refiners will begin investing to process it and come to depend on the Synbit and Dilbit for a significant ...


Operating a fouled process unit? What is it costing you?

ITW Online Cleaning Technology, applied proactively during a run, restores unit performance to near start of run conditions in as low as 24 hours oil-to-oil without the need for opening equipment. By utilizing ITW’s patented asphaltene stabilization and/or polymer modification technologies, ...


Opportunity crudes - chemical tools solve intractable processing problems

A 100,000 BPD refinery originally designed for lighter crudes struggled with serious desalter performance problems and unacceptably low throughput when processing blends of relatively heavy, acidic feedstocks, including Dar, Ratawi, Eocene, Duri, Stybarrow and Enfield. When a costly combination ...


Opportunity knocks

A group of interesting articles* deals with opportunity crudes, a mixed breed that includes very heavy, sour and high total acid number types as well as those with unexceptional naphthenic acid content but which do have significant concentrations of aliphatic acids or possess the ability ...


Opportunity or Annoyance?

Price differentials between conventional and opportunity crudes compel refiners to process increasing percentages of lower valued opportunity crude. However, as many refiners have learned the hard way, opportunity crudes are tied to unique processing challenges. Furthermore, existing crude ...


Processing heavy Canadian crude

Reducing crude oil cost is the major incentive driving crude and vacuum unit projects to handle heavy Canadian crudes. But such crudes–Albian Heavy, Christina Lake, MacKay River and others derived from oil sands–today present refiners with a unique set of problems not just ...


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. ...


SENTRY Guard Portfolio

Protect your catalyst. Protect your bottom line. Opportunity feed sources have extended the range of poisons that hydroprocessing unit operators must face. Many of the contaminants can cause severe catalyst poisoning, even at very low concentrations. Catalyst contamination negatively impacts ...


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 ...


THIOLEX™ caustic extraction of acid gas

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 ...


Tray designs for extreme fouling applications

Today refiners experience a lot of problems with processing of opportunity or heavy crudes. Such crudes have very high sulfur content and require the addition of amine scavengers before desalting. These amines decompose in the heater and create ammonium chlorides in the presence of water ...


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 ...


Using chemical analysis to diagnose amine upsets

Using chemical analysis from your amine supplier to diagnose your amine system? Understanding the link between the analysis report and the amine system operation can be foggy. MPR Services, Inc. shares clear understandings and provides solutions to amine hygiene.


Why do many crude/vacuum units perform poorly?

In many cases it’s because the original design was based more on virtual than actual reality. There is no question: computer simulations have a key role to play but it’s equally true that process design needs to be based on what works in the field and not on the ideals of the ...
