Automated Soluble Solvent Control System

Introduction:
Originally designed to automatically control a Rubber Primer / MEK process application line where normal changes to the process concentration constantly occur due to evaporation of MEK and the manual addition of Rubber Primer concentrate, the Automated Soluble Solvent Control System can be utilized for similar applications. Using the refractive index measurement of the MPR E-Scan, this system automatically provides accurate process control and reduced labor costs. This system is designed for volatile applications where explosive environments are likely to occur.


System:
The dilution liquid is stored in a level-monitored reservoir. Status LED lights easily allow operators to identify when additional dilution liquid is needed before the reservoir is empty and automatic dilution is disabled. A separate transfer pump is provided that allows the dilution liquid to be transferred into the reservoir with an automatic shut-off when full.
The control panel with MPR E-Scan console, relay box with status lights and intrinsically safe barrier box is mounted in the “safe area.” The MPR E-Scan sensing head and the dilution liquid storage reservoir (with pumps and level transmitter) is installed in the “hazardous area.”


KEY BENEFITS:
 Accurate Process Control
 Operate economically Optimize man hours
 Decreased offline testing

Application:
The MPR E-Scan monitors the solution percentage to ensure the desired mix is maintained. When a set dilution point is reached, the system automatically injects the dilution liquid to the process. The injection is configured to occur incrementally with an appropriate delay between injections to ensure thorough mixing of the process and to prevent excessive dilution. A manual interrupt switch for the dilution liquid injection is provided for circumstances where manual control is needed.


Conclusion:
By installing the Electron Machine Corporation Automated Soluble Solvent Control System a company can insure an accurate process control resulting in increased profit from economical operation. Optimize the work force man hours from no longer needing to manually control process dilution and a decrease in offline testing. Increased quality control by maintaining a desired process solution dilution.

INTRODUCTION

The Electron Machine Corporation has been designing and manufacturing in-line process refractometers since the early 1960s. Our focus is providing simple, rugged, and reliable instruments that provide value over time with accurate measurement, minimal maintenance,and long service life.
The MPR E-Scan is a hybrid-digital critical angle refractometer. It is used to measure the refractive index of process fluids and may be used as an error indicator or an integral part of a complete process control system.
The MPR E-Scan is calibrated and temperature compensated to your process specifications.
It is ready for installation and immediate use when received. Calibration procedures are available to change system parameters and allow the refractometer to measure different process fluids.

Improve large scale ice cream production and quality control by accurately measuring milk and sugar concentrations with inline process refractometers. The refractometer directly measures dissolved solids, which can be easily converted to Brix. This measurement is unaffected by bubbles or suspended particles.

The Electron Machine MPR E-Scan refractometer is used to measure both the dairy concentration as well as the sweetener (sucrose, fructose, etc.) Brix level going into the mixing tank. This in-line measurement allows real-time trimming of both ingredients to meet the final target concentration in the mixing tank. Additional measurement of the mixed product is used for further adjustments to the composition before packaging.

By installing the Electron Machine Corporation MPR E-Scan a factory can insure an accurate process control resulting in consistent ice cream quality. Thus, increasing profit from economical operation. By maintaining a desired process concentration there will be a decrease in offline testing and an increase quality control. This results in the ability to optimize work force man hours and eliminate unnecessary product waste saving the factory time and money.

Today, many engineers do their product selection largely via the Internet, and usually by just comparing specifications between manufacturers. While this provides a fast, efficient, and objective means to narrow down prospective vendors, it totally ignores a critically important (albeit subjective) component to the success of their project - the vendor's Customer and Technical Support infrastructure.

When choosing a vendor for process instrumentation (industrial refractometers for instance), it's imperative to include an evaluation of the vendor's Technical Support and Customer Support infrastructure. Realizing what these professionals have to contribute, and taking advantage of their knowledge and talent, will save time and money, and greatly contribute to a successful project outcome.

Understanding Why Technical Support and Customer Support are CriticalIt's all about two things:

• Experience
• Attitude
  

Experience"If you think it's expensive to hire a professional to do the job, wait until you hire an amateur." Red Adair

By the nature of their job, Customer Service personnel are current on new products, their capabilities and their proper application. Unlike anecdotal information available on the Web, support personnel have first hand knowledge and hands-on experience. They've seen successful (and unsuccessful) product implementation scenarios and are eager to share. A brief discussion about your application with a specialist will guide you toward selecting the best equipment for the requirement. Also, because they are exposed to so many different applications and situations, Customer/Tech Support personnel are a wealth of ancillary application knowledge.

As a project engineer, you may be treading on fresh ground regarding some aspects of fully understanding the project you're working on. You may not have a full grasp on how to handle a particular challenge presented by the application. Calling upon a source with past exposure and experience to your current application prior to product selection will provide a very real, and very valuable benefit.

Attitude:"Customer service is not a department, it’s everyone’s job." Anonymous

Choose a company that places a huge emphasis on customer service and do some due-diligence. Determine if they're merely providing lip service, or if extreme customer service oozes from the company pores.

Sam Walton, the founder of Walmart once said "The goal as a company is to have customer service that is not just the best, but legendary." Make sure the vendor you're evaluating sees things the same way.  While reviews or testimonials (if there are any) can be helpful, they should be viewed judiciously. You're going to have to talk to people and get your own "gut-feel".  Do the employee's seem upbeat and happy? Are they knowledgeable? If they can't answer a question, do they volunteer to connect you with someone who can?  Are they enthusiastic?

As an engineer who designs or manufactures a product or process, it's strongly recommended you make the effort to research, contact, and get a first-hand feel for your prospective vendor's Customer and Technical Support Team. Learn about their product and application knowledge, their experience and their commitment to excellence. Taking the time to do this will raise the likelihood that your project will come in on time, on budget and shine brightly upon you.
