RJM International launches new business venture in the United States

RJM International, the UK-based provider of emissions reduction technologies, announces today the launch of a new business activity with Systems Analyses and Solutions, Incorporated (SAS) located in Owasso, Oklahoma, USA.

SAS was originally set up in 2006, providing advanced engineering analysis and scaled testing of combustion systems, including performance characterization of catalytic systems, to businesses across a range of industrial sectors in the United States.

Over that period, RJM has increasingly been working with SAS on a number of European emissions reduction analysis projects, exploiting its state-of-the-art expertise and advanced analytical tools developed in-house by SAS and unavailable elsewhere.

It is because of this increasingly significant shared business activity that RJM was keen to formalize the relationship between the two parties and create a new company with enhanced resources, a strengthened management team and therefore the ability to win new, larger assignments across a wider range of industrial sectors, throughout the world.

Commenting on the new SAS venture, John Goldring, Managing Director of RJM said, “We’ve been working with the SAS team for a number of years now on several projects such as detailed CFD analysis or scale-model airflow distribution analysis, where attention to detail and the highest levels of precision can make the difference between meeting a new, reduced NOx threshold or missing it altogether.

“There are a number of industrial sectors which could benefit from SAS’s extensive experience in the chemical and hydrocarbon industries plus their background in forensic  engineering – as well as our own core market in the power generation sector at large combustion plants – and we want to enable the new SAS business to achieve its full potential.

“By joining forces, SAS now has the resources to build on its previous successes and become a significant global player,” he said.

Supporting that viewpoint, Joseph D. Smith, SAS President said, “We are very excited at the prospect of linking up with the RJM team to facilitate new business growth not just in the USA but all over the world.”

“Our high quality engineering team, all with advanced degrees, represents over 100 plus years of practical experience solving real industrial problems.  With our new office and testing laboratories located in Owasso, Oklahoma, we are now ready to aggressively move forward in this business venture with RJM.”

“My priority for the next 12 months will be to meet potential clients in the power and process industries to introduce our well proven solutions to meet the critical challenges in the process and power generation business,” he added.

Slug Catcher Case Study

A “slug catcher” in a gas pipeline is a section of pipe that has been purposely “oversized” to slow down the gas velocity and allow liquid water to drop out of the gas flow. This arrangement is usually placed after a collection header from a natural gas field, and is used to eliminate large “slugs” of water coming off of the field.

A client had a gas production field, which could produce ~ 500 MMSCFD of gas. When the production was increased to ~1500 MMSCFD of gas, water in the piping system would overwhelm existing water cyclone separators and “trip” the compressors off. A slug catcher had been installed upstream of the cyclones, but was operating unsatisfactorily. Working with our client, the existing slug catcher design was analyzed, and found to be only about 20% efficient in water removal. Through an iterative process, an optimal modification was developed which gave in excess of 90% removal efficiency – at substantial savings compared to design/fabrication/installation of a new slug catcher.

Abstract

A detailed computational fluid dynamics (CFD) model of an elevated multipoint flare has been developed using a proprietary flare modeling tool.  This tool has been used to simulate the ignition phenomena for this particular flare at a gas flow rate of 350 Tons per hour (TPH). Simulation results have been directly compared to operating test data for this flare.  Verification results has demonstrated the ability of this virtual tool to replicate the measured flame spread rate and reproduce the measured pressure wave generated during the ignition event.  Based on this verification, the tool has been used to conduct over sixty separate simulations to investigate the ignition behavior for this flare.  Results from these simulations clearly show the critical effect of ignition delay on the magnitude of the pressure wave generated during ignition.  The main conclusion drawn from this analysis is that the ignition system’s reliability to quickly ignite the flare gas above the flare tip is critical to safe operation.  Results show that a delay of from 0.3 to 0.6 sec has a major impact on the magnitude of the pressure wave generated during flare ignition.  This is especially important given these results were based on a low flow rate which is approximately one-tenth of full flare operating conditions.  At higher flow rates, a pressure wave capable of damaging local equipment and injuring plant personnel may be possible.  Based on this observation, additional work has been conducted to assess the explosion potential.  Results of this work will be discussed during the presentation.  This tool has also been used to evaluate and identify more efficient and reliable ignition techniques to reduce the explosion risk caused by excessive flare gas accumulation above the flare tip.

Development of Kinetic Based Model

Our client is fabricating and designing state-of-the-art fuel cells for industrial applications. Their technology used a catalyst to strip off hydrogen atoms from natural gas for use in the fuel cell. In order to control the process, knowledge of light-off position was critical.

Working with SAS personnel, data from their process was used to develop a kinetic model of the process. This model was the set-up in a Visual Basic program so the client could rapidly determine light-off locations as a function of various input parameters.

Design and Operation of Process Development Facility

A client wanted to investigate the potential of a new chemical conversion process. Kinetic modeling of the process indicted that potential yields in excess of 30% were possible, though previous efforts had only achieved 20% yields.

SAS personnel proposed a novel reactor to achieve the conditions, and were awarded the contract to design, fabricate and operate a
“bench scale” process facility. Data collected from the facility demonstrated that the kinetic models that were employed were too optimistic and that previous results of about 20% represented maximum yields.

SAS personnel were able to achieve state-of-the-art results with reactor and process operations.

Noise Reduction in Petrochemical Facility

A western chemical plant was experiencing excessive noise from a reactor and causing numerous problems with plant neighbors. Working with plant personnel, SAS modeled the system and first corrected flow distribution problems.

Follow-on analysis indicated that the reactor itself was producing the noise via a Riejke-tube phenomenon. Instead of an expensive reactor redesign, SAS recommended installation of a Helmholtz resonator in the exhaust stack, tuned to the frequency of the reactor noise. SAS accomplished the design and fabrication of the stack replacement and was on-site for the installation.

At start-up, noise levels were reduced by over 20 dB, and concerns from plant neighbors were eliminated.
