Expanded Chemical Plant Process Controls to Yield Savings

Expanded Chemical Plant Process Controls to Yield Savings

RESULTS:

  • The solution saved the customer two weeks worth of time and labor
  • The dollar value associated with this is a man-hour savings of $2,000
  • The resulting value to the operation was an additional 6.1 million pounds of product manufactured

Application

Automated, distributed control system for industrial organic processing of specialty chemicals.

Customer

Specialty contract chemical manufacturer, producing sulfur dioxide as well as other reaction and distillation services.

Challenge

This involved the installation of a new sulfur burner system at the facility. The production process burns molten sulfur to create sulfur dioxide (SO2) which then is absorbed in towers converting it to ammonia bisulfite (ABS). Ammonium bisulfate, also known as ammonium hydrogen sulfate, is a white, crystalline solid with formula HSO4. It is the product of the half-neutralization of sulfuric acid by ammonia (formula: (NH4)HSO4). The ABS is used to make ammonium thiosulfate (ATS), which is used as a component in fertilizer. This facility’s chemical processing system is automatically controlled by Emerson DeltaV and CHARacterization Module (CHARM) technology. DeltaV is a distributed control system that helps improve operations by harnessing predictive technologies in an easy, intuitive, and interoperable way. Emerson Asset Management Software (AMS) was also an integral part of the installation success. AMS provides a single application for predictive diagnostics, documentation, calibration management, and device configuration for managing field instruments and digital valve controllers.

Solution

Since this was a new installation of an expansion of plant capabilities, Novaspect engineers recommended AMS as a commissioning tool. By using its capabilities, we provided additional value to the commissioning with instrumentation set up, configuration and troubleshooting.

Benefits & Measurable Results

Combining the DeltaV CHARMs solution with AMS and the DeltaV Batch program, the operation gained measurable benefits:

  • The solution saved the customer two weeks worth of time and labor. The dollar value associated with this is a man-hour savings of $2K. The resulting value to the operation was an additional 6.1 million pounds of product manufactured.
  • Customer experienced improved startup time relative to other comparable startups.
  • Benefits of diagnostic and troubleshooting capabilities will shorten future repair cycles, as required.
  • Process time-savings: To comply with standard procedures, technicians normally need hot-work permits to open any control cabinets. By using AMS they can bypass the permitting process and enter electronically via DeltaV, thereby avoiding physical entry into cabinets, all accomplished by using a HART communicator. The results yielded valuable time savings.
  •  Due to the success of this project, the customer has accelerated the use of AMS at other production facilities.

Plant Manager: “During the commissioning phase of the project, representatives from Novaspect help set up the DeltaV system. In that time, we were taught the ins-and-outs of AMS, including the alarm features and instrument templates. This provided valuable information for us to make commissioning and troubleshooting more efficient. The success of this project relied heavily on the knowledge shared about AMS to provide live diagnostics of instrumentation and how to correlate them to issues seen in the process.”

No matter what segment of the refining industry you are in, maximizing efficiency and increasing throughput are the keys to profit maximization. At Novaspect, we take your company’s manufacturing uptime just as seriously as you do, and we go the extra mile to help you find solutions that improve all facets of your process. Whether you’re looking to streamline processing, transmission or production, we’ll help you optimize your overall approach for maximum efficiency.

We understand refining

One of the problems we keep seeing again and again in the refining industry involves bottlenecks developing where integrated systems are concerned. Just one component that isn’t sized correctly or has too short a lifespan can create havoc for your whole system. Our years of expertise coupled with our capability to deliver can help alleviate these system choke points with innovative design and properly installed solutions.

Recently our team of professionals was called upon to help find a permanent solution for a large refinery processor plagued with bottlenecks that were having a detrimental effect on operational efficiency and cutting into the plant’s possible profits.

Finding solutions

The problem involved the plant’s gas-oil hydrotreater (GOHT) and distillate hydrotreater (DHT) in the production of light cycle gas oil (LCGO). The high-pressure separator let-down service was constantly being flagged as a system constraint, resulting in a system shutdown.

Further compounding the problem was an incredibly short lifespan on both valves. Valve and trim washout, coupled with the excessive vibration of the two valves, were creating packing problems and premature yoke failure. This was being caused by improper valve sizing, which resulted in choked flow conditions. Necessary repair and replacement of the valves was taking the whole system offline every 15 months, greatly impacting the company’s bottom line.

That’s before Novaspect got involved.

Our team wasted little time diagnosing the problem and quickly collaborated with system engineers to devise a solution that solved a number of the plant’s issues. First, we dug into the whole system to understand the complete set of conditions that went into creating the underlying problem. The outgassing conditions were present in both normal and temporary feel slate conditions.

Innovating solutions

Once we had a better idea of the valve flow coefficient required, the solution wasn’t far behind: Novaspect designed a customized Fisher HPAS valve specifically for this company’s process. The valve’s body was redesigned to meet the piping and material requirements of our client, as well as to prevent the choked flow, vibration and erosion that had been wreaking havoc.

The impact that Novaspect’s solution had on our client’s process system was evident almost immediately after the new valves had been installed, as the complete project’s return on investment was realized with 24 hours. Further, the new customized valve solution has not failed in the 96 months since installation, greatly improving on the previous valves’ 15 months. Ultimately, this client’s system efficiency, safety and production have all been enhanced thanks to our expert knowledge and innovation.

At Novaspect, we seek to understand the challenges our customers face so we can design systems and solutions that simply work. We’re committed to delivering the right innovation to the right people at the right time. Contact us today and let us help you solve your challenges together.

Oil drilling company achieves faster well startup and decreases time to net oil

Results

  • Faster well startup results in decreased time
    to net oil
  • One week reduction in startup time provides
    up to 8,000 barrels of additional production
  • Financial gain up to $720K per well

 

APPLICATION

Upstream heat treating of petroleum production fluid to break emulsions into phases of oil, gas, and water, plus measurement and monitoring.

CUSTOMER

Mid-size North Dakota upstream oil field exploration and production company is drilling and starting up new wells.

CHALLENGE

The customer was seeking the most time-effective and cost-efficient system to bring wells online and into production. The on-site solution must include technology for separating oil and water as well as accurately measuring and monitoring each component.

SOLUTION

The Novaspect / Emerson team of engineers designed and commissioned vertical and horizontal heater treater units equipped with advanced measurement and monitoring capabilities. Their solution resulted in a time savings up to one week per well with a financial gain of up to $720K per well. A producer commissioning one well per month can deliver up to $8.6 million of additional crude to market. Other benefits include decreased flare gas to storage tanks, significantly reduced shrinkage, and improved allocation measurement, a 28% improvement over conventional methods.

Heater Treater Design Principles

The fundamental principle behind upstream heater treaters is to provide heat to the produced fluid to assist in breaking emulsions combined with sufficient retention time for the oil, water, and gas phases to separate out based on their differences in density. The vessel size is determined by the estimated production volumes and properties of the crude to be treated over the life of the field. There are two types of heater treaters: vertical and horizontal.

Vertical is the most common type of treater due to its low cost, reduced complexity and ability to gravity feed produced liquids to the tanks. Horizontal tends to be more complex and at a higher cost, but a longer “U” style firetube allows for greater heating capacity and treatment rates. Horizontal treaters are more efficient but typically operate at higher pressures since they lack the vertical height to boost the produced liquids to the tanks.

This Novaspect / Emerson solution included:

Solve Performance Problems with One Solution

Loop tuning is the process of adjusting a control loop to achieve the desired effects. A control loop is an industrial control system used in application machines that need constant control. It is a feedback process that strives to correct any differences between at the set point, and the measured variable. The measured variable may be higher or lower than the set point and controller implements corrective measures to return the variables to the set point.  Loop tuning is a complicated process, but when done right it can increase product uniformity and enhance the control process. There are different ways for loop tuning. Lambda tuning is the standardized approach which uses Proportional-Integrative-Derivative (PID).

Loop tuning is mostly used in closed loop systems. Novaspect uses Lambda PID which uses a feedback control algorithm. The use of this algorithm cuts across various industries from oil and gas to metal and mining, power production, refining among others. PID controllers aim for a constant control loop that increases the process maintenance depending on the variable loop. Controllers enhance the running of the process. Lambda loop tuning system can be tested before final setting and implementation.

During the setting stage, a few steps need to be followed to ensure appropriate configuration.

Set Objectives

Set what the controllers should achieve during the process. Definite tuning parameters to be used in the process should be stated. The usual process parameters include gain, dead time, a time constant, proportional band and integral.

Prioritize Loop Controls

Control loops should be setups for fast or slow implementation especially for interacting loops. When control loops are set on an equal level, they cannot achieve stability.

Testing

Place the controllers in manual mode and test the process for the output.  Make changes in small percentages depending on how sensitive the process is until you achieve the desired output.

Calculating tuning Parameters

The parameters must be calculated to find out the parameters that optimize the output of the process. Engineers do the necessary calculations to be used in the loop tuning. An example of set parameters may be:

  • Dead time: 1 minute 30 seconds
  • Integral: 15 min/rep
  • Proportional Band: 50
  • Gain: 1
  • Time constant: 7 minutes

Solve hardware challenges

The major hardware challenges that affect the effectiveness of the process are the type of valves used. The right valves should be put in place to increase efficiency and effectiveness.

Repeat Testing

This is just a confirmation process to check whether everything is running smoothly.  Repeat testing should be approved by engineers before PID is finalized.

Finalize

If the results of repeat testing are satisfactory, it’s time to finalize the setup process and go to live production.

Novaspect has a team of engineers and other qualified staffs who have vast experience with other control loops. We understand that control loops are crucial in ensuring the smooth running of your loop system. Novaspect will study your current loop system to capture all the vital data before upgrading to PID controls.

The new loop controls will improve the efficiency of the control process and increase product uniformity. Novaspect engineers will supervise the whole process to ensure a smooth transition.  An improved loop tuning can be attained easily with the help of Novaspect professional team. Feel free to contact Novaspect for further details on loop tuning. We look forward to working with you.
