Measure & Analyze Approved “Over-Process No More”–using liquid Conductivity Tech. to Eliminate Processing of Zero Value Liquids A Specialty Alloy and Components manufacturer had a project to install a new tank storage system to house and process liquids generated from their chemical operations. An element of the design focused on storage capacity. It was discovered as part of modeling the new system design that not all liquids coming to the storage system would require processing, as some of the liquids historically being sent to storage had zero value. The zero value liquids, being berm and sump “water”, had historically been mixed with all other liquids and sent to storage. The calculated volume of zero value liquids was sizeable enough to impact the initial project costs. Due to the potential for project and long-term processing savings, the decision was made to engineer a solution to remove zero value liquids. The project scope established that the new storage facility would store only liquids that required processing and remove liquids from the system that provided zero value. To do this, a process needed to be established where a “real-time” measurement of liquids in the berms and sumps could be obtained and analyzed to insure the material was within established acceptable limits. The major benefit was not processing liquids that provide zero value and that only add cost to the bottom line. A side benefit of these devices is the Environmental benefit. Based on the successful trials and cost savings (<6 month ROI) in Operations, we are currently looking to expand the use of these devices on other sumps and bermed areas, for both cost savings and environmental benefit. A conductivity probe was selected to measure the liquid streams, based on a standard that was developed from Rain, City, and Industrial Water measurements. The device was then placed in a process line with some programming that allows for the sample of the liquid, comparison of the measurement, and then discharge of the liquid to one of two destinations based on a set of pre-defined limits.

Measure & Analyze Approved Lessons learned – How to optimize gas turbine performance in a power generation plant in Mexico Mexico is a net importer of natural gas, mostly via pipeline from the United States, and its natural gas demand is rising because of expanding power generation capacity. Many of Mexico’s newer power plants are highly efficient, gas-fired, combined cycle plants which integrate gas and steam turbines. Each power plant that use natural gas has to be strictly controlled in the quality and flow rate to improve the Turbine performance. For this reason, Grupo Avanzia was looking to develop a project for a reliable system to measure, regulate and analyze the quality of gas for a power turbine. Grupo Avanzia is a worldwide leader that build and operate industrial infrastructures based on excellence in integration and technological innovation. "? Excessive CAPEX costs? ? High content of moisture on gas before going into turbine. ? Poor quality of gas." "? Correct separation of moisture through a reliable gas filtration. ? Protection of the Turbine -? avoided 60 hours per month of maintenance costs? ?? ? Accurate flow rate measurement at process conditions ? Increase of turbine capacity in 5%." Emerson was able to provide the perfect solution for the customer - One Integrated Measurement Skid System comprised of one (1) liquid separator, one (1) coalescing filter w/ condensate tank, one (1) gas regulating skid, one (1) gas metering skid and one (1) natural gas analyzer skid. This skid-mounted equipment is completely piped, instrumented, wired, and assembled, ready for use.

Measure & Analyze Approved Challenges of Processing Opportunity Crudes "As refiners target improved operating margins, one of the likely methods to accomplish this is through the processing of opportunity crudes. Opportunity crudes may command a discounted price due to known processing issues, or they may be new crudes with unknown or poorly understood properties and processing challenges. At stake is higher unit availability, reliability, and run length between major turnarounds.? P66 is one of the many refiners trying to take advantage of processing these crudes while at the same time trying to find a balance of high unit availability. One of the main issues hindering high availability is the unknown corrosion effects of the crudes on the plant infrastructure. To try to slow these effects P66 has implemented various corrosion inhibiting chemicals" Considering the many different opportunity crudes available it’s difficult to determine which corrosion inhibiting chemicals will work best with each slate. The Permasense probes continuously monitor the corrosion rates and help determine what corrosion inhibiting chemicals works best for the different crude slates. When P66 first implemented the Permasense monitoring solution they discovered that one corrosion inhibiting chemical was no longer needed and realized a $375k in savings that first year. 64 Permasense wireless HART probes were installed in highly corrosive applications to continuously monitor the corrosion rates. The wireless data is sent back every 12 hours to the Emerson WiHART Gateway which transfers the data to the Permasense data manager to show corrosion rates over time.

Measure & Analyze Approved Increasing Fuel Ethanol Fermentor Capacity with Advanced Guided Wave Radar A 100MMGPY ethanol plant in the Midwest has increased ethanol production by nearly 5% - an estimated $8 million per year in revenue by installing guided wave radar gauges in their fermentors. Variable fluid density and foam had presented an insurmountable challenge to other level technologies. High signal strength and advanced features of the Rosemount 5300 proved to be reliable and allowed higher fill levels and eliminated risk of overfilling. Best practices for installation and commissioning, how features within the 5300 that allow it to make this specialized and difficult measurement, and business impacts will be discussed. Variable fill density and foam caused by CO2 production challenged DP level measurement. Overfill resulted in foam exhausting through PRV or being drawn into vapor scrubber. EPA reportable spills could also result. To prevent this the plant was filling vessels 3-6 feet lower than maximum capacity with resulting loss of production capacity. Raising the fill height of the fermentors will result in an estimated $8 million of annual revenue from ethanol sales; 4,400 gallons per batch, or 5.5 million gallons per year, production increase has resulted. Reliable level measurement allowed operations to top off fermentor during batch to optimize capacity without risk. Environmental incidents and foam venting have been eliminated. Rosemount 5301 Guided Wave Radar gauges were installed on each vessel. High signal strength penetrated foam layer producing high signal to noise. Variable foam level and density was a challenge to repeatability of measurement.? Threshold level crossing detection function enabled top of foam to be tracked as measured level independently of amount or density of foam.

Measure & Analyze Approved Simplicity Meets Flexibility -? Reliable flow measurement system for LPG Underground Storage "The LPG is the most used hydrocarbon in Mexico specific for living places, around 80% of houses are using it that means if there is a problem in the supply chain it impact directly to the basics needs of the population. One way to mitigate this risk is to count with a properly storage system.? The current storage capacity in Mexico is 2.64MMb which leads to an average of 2.37 days of storage in the areas with a big consumption and there is a limited infrastructure to deal with contingencies. The project scope is regarding a 20-yr leasing contract of underground storage using salt caverns with a capacity of 1.8MMb.? This is a “take-or-pay type of agreement”. As part of the scope a Metering Skid System was included." "? Limited LPG supply for the high demand season ? Have the proper storage capacity in case of contingencies as hurricanes, social events, etc. ? Frequent delays caused by LPG Ships offloading time ? High operational and maintenance costs from cryogenic storage tanks from main supplier which is the PEMEX Pajaritos Terminal." "1. 8% Reduction on energy costs instead of using cryogenic tanks. 2. Increase the offloading Ship time - 10 day reduction in delay? 3. 30 days increase the storage capacity in to prevent LPG supply contingency. 4. Capability to offloading in each moment directly to underground storage. 5. Improve LPG availability on winter 6. savings in LGP imports 7. Decrease the overall costs in 12%." Emerson was able to provide the perfect solution for the customer – an LPG Custody Transfer Metering System comprised of (3) 8” ANSI 600 Coriolis meter runs, 16” ANSI inlet and outlet with 12” ANSI 600 headers, an 8” inlet and outlet prover and a control panel with Flow Computers and accessories.

Measure & Analyze Approved Wireless instruments provide asphalt terminal with accurate,cost-effective process/inventory control An asphalt terminal in the Midwest supplies liquid asphalt for road paving operations throughout the region. Different customers have varying specs they must adhere to and rework due to incorrect mixes is costly. Wireless level and flow instruments were added throughout the facility to replace aging/ inaccurate measurements, manage inventory levels, and verify the right components go into each batch. Ease of implementation of wireless instruments enabled them to quickly and cost-effectively gain insight into their processes. Tighter batch quality control removes risk of shipping bad mixes which can cost in the millions of dollars and having real time inventory allows for instant notification if a tank level changes when it isn’t supposed to, leading to safer and more profitable operations. The terminal was using traditional float and tape level measurements on large asphalt tanks and having difficulty keeping accurate inventory. The old gauges often gave false readings. Poor level monitoring also allowed for incorrect mixtures getting to loadout due to operator error. Incorrect road mixes applied before being caught had previously cost the company millions in rework expenses. Installation of this system allows for tighter batch control and inventory accuracy has improved from +/-5% per month to 4 in 45000 Tons in some cases! Wiring costs to implement this solution would have cost over $100K and adding instruments for new tanks is a cinch. Use of this system recently prevented the potential release of 1.5MM gallons of asphalt due to a valve that broke over a weekend. Wireless RMT 2051L transmitters were added to 30+ storage and mix tanks while THUM adapters were installed on Coriolis meters. A Wireless gateway with Ethernet IP collects the data and connects into an PLC which runs the inventory system, allowing accurate tracking of where product is being sent for batch and mixing operations and provides instant visibility to abnormal changes.

Measure & Analyze Approved Continuous steam trap monitoring improves cogen plant efficiency, reduces risk of equipment damage ADM’s cogen plant supplies steam and power to crush and refinery operations in the facility. ADM was looking for ways to increase energy efficiency and steam trap maintenance was identified as an area for improvement. An online steam trap monitoring system was installed using Rosemount’s wireless 708 acoustic transmitters and SteamLogics software to catch failed or leaky traps when they occur rather than on an annual audit basis. Implementation took only 6 hours and showed an almost immediate payback by identifying 3 leaking traps that had gone undetected. Annual steam trap audits are only snapshots in time. One can’t tell at the time of the audit whether the trap is sticking or leaking intermittently and when a trap is found to be failed there is no way to know at what point between audits it failed – making it impossible to quantify the amount of losses. Old audit practices were inadequate for ADM’s drive to improve energy efficiency. At startup three traps were immediately identified to be leaking. It had been over a year since the last audit. Assuming those traps had been leaking for half that time, estimated preventable steam losses were nearly $20K! Knowing the health of all high-value traps will allow ADM to actively maintain their steam system, reducing lost money due to failed steam traps and increasing plant efficiency. ADM and Emerson collaborated to implement continuous steam trap monitoring on 26 of their most critical steam traps in the Mankato cogen plant. Rosemount 708 transmitters and SteamLogics software were installed to give the plant real-time accurate data on the performance of these assets. A newly designed high- |
