 Conferences Provide Critical Professional Development

In the busy world of petroleum testing equipment, it’s difficult to carve time into the schedule for professional development.  It’s also critical. Attending conferences to swap best practices, showcase emerging technology, and share changes in industry standards is part of the job – and not one to be neglected. Thus far in 2018, L-K has exhibited at three important industry conferences.

The most recent, held in Lafayette, LA, was hosted by the Acadiana Flow Measurement Society on April 10 and 11th. Industry experts gathered at the annual show to discuss measurement equipment, problems, and solutions. L-K exhibited at the show for the first time and featured new security sealing devices as well as glassware, including Miller-Weber of Texas (MWTX) centrifuge tubes, thermometers, and hydrometers.

Security sealing devices provide evidence of theft or tampering of valves, piping junctions and other devices, and limit access to at-risk points such as lock nuts and needle valve handles, solving age-old security problems.

Having them in place facilitates compliance with OOC (Offshore Operators Committee) Best Practices and BSEE (Bureau of Safety and Environmental Enforcement) requirements. Security sealing devices are manufactured on-site and are readily stocked. Custom devices are available upon request.

In our on-site accredited ISO/IEC 17025 laboratory, MWTX manufactures and calibrates a full range of liquid and glass thermometers and hydrometers that meet an array of temperature and gravity measurement needs. Centrifuge tubes are heavy duty and handcrafted with ceramic yellow paint that’s easy to read. All L-K and MWTX products are designed to make measurement safe, accurate, and simple. L-K will have exhibited at the G.C.C. (Gulf Coast Conference) twice in 2018 – once at the Hurricane Harvey postponed show in January. In October, we will be in Galveston for the fall G.C.C.

The American Petroleum Industry’s (API) Spring Committee on Petroleum Measurement Standards (COPM) met in Dallas from March 12th through the 16th. It’s a critical meeting that emphasizes API standards and best practices used throughout the industry to promote safe and environmentally sound operations. Technical committee meetings include topics such as current and future research and development on measurement techniques and equipment, updating and creating industry standards, and changing government and regulatory guidelines. Measurement training and education is integral to L-K’s core mission, and API’s Spring Committee on Petroleum Measurement Standards provides opportunities for growth that translate to improved products and services.

Professional development opportunities such as these allow for collaboration among industry stakeholders, ensuring L-K will continue to “Demand a Higher Standard.”

HAPPY ANNIVERSARY to L-K! To celebrate three years of new ownership, we held a TX-LA style shrimp boil. Delicious!

 Centrifugation: Still Relevant, Always Superior

Water is an essential component in so many aspects of life, including in our bodies and on our planet. But water in crude oil and petroleum products is problematic – and can be costly if included erroneously in the “net dry oil” calculation. Assessing the amount of basic sediment and water content (BS&W) in crude samples is critical, yet accurate analysis is difficult.

Currently, the oil Industry uses three different static methods to determine water content in oil: Karl Fischer titration, a distillation method called the Dean and Stark Test, and the oldest and most widely used method, the centrifuge test.

Although Coulometric Karl Fischer is very accurate (at .5% water, it is four times more accurate than centrifugation and two times more accurate than distillation), it’s not practical for the field, affecting use in custody transfers and sample analysis. The Dean and Stark distillation test is used to settle disputes when parties can’t agree on centrifuge results, but is time consuming and can only be conducted in a laboratory setting. Additionally, neither of these methods can determine sediment content. The centrifuge, the tried and true method dating back to the separation of cream from milk in the 15th century, stands alone for determining BS&W in crude oil samples in the field and in the laboratory.

The Original Melton Centrifuge
Manufactured in 1957

In this method, L-K Industries set the bar. The Melton Centrifuge became the hallmark of the company and set the oil testing industry standard for centrifugation. In 1962, ASTM standards were released based on the Melton Centrifuge, and to this day it stands as the single invention that changed the course of the oil testing industry. William L. Melton, in his United States Patent application, described the device as an “invention [that] relates to a centrifugal machine for testing oil that must be heated to a predetermined temperature, and more particularly to a machine for testing crude oil in the oil fields…”

Today’s  L-K centrifuges exceed API/ASTM Standard Requirements and customer expectations. Equal volumes of oil and solvent are placed in a graduated tube. After centrifugation, the volume of the higher gravity water and the sediment layer at the bottom of the tube is recorded. In the upcoming Benchmark Platinum, ultra high-speed capabilities of 2700-3000 rpm will further improve separation of elements and yield more accurate results. Additionally, with its Class I, Division 2 status, refined features, and interactive display, centrifugation will be the field and laboratory method of choice in the petroleum industry. 

The Benchmark Platinum Centrifuge is the third edition of the Benchmark series. It will feature an all-in-one interactive screen, ultra-high speed for better oil separation, and a redesigned lid for easier bowl access. L-K is excited to bring the Platinum to customers in 2018!

Temperature Matters: Precision Thermometers, Hydrometers

Petroleum measurement calls for precision, validity, and reliability. It requires dependable, exacting instruments like Miller-Weber thermometers and hydrometers.

In 2016, L-K Industries added another layer of industry-leading merchandise to our oil testing equipment when owner Eric Calderon purchased Miller-Weber of Texas (MWTX). The former New York thermometer manufacturing company was reopened in Houston, offering a full range of calibrated liquid and glass thermometers from the ISO/IEC 17025 accredited on-site laboratory.

The first batch of T-SPEC 9 and ASTM S 59F thermometers produced in the Houston lab! The glass-blowing and etching facility produces high quality thermometers and performs instrument calibrations.

Each calibration certificate issued by MWTX contains the measurement results, the measurement uncertainty, and/or a statement of compliance with an identified metrological specification. Says Calderon, “We can confidently offer those who purchase our merchandise a testing and calibration service that’s truly unique. For customers who demand a higher standard, we can deliver.”

Beyond the petrochemical industry, temperature matters. Those demanding higher temperature measurement standards include dairy processors, who follow the FDA’s Pasteurized Milk Ordinance (PMO) to ensure the safety and sanitation of “Grade A” milk products.

Food service employees across the country also follow strict temperature guidelines, as documented in Your Gateway to Federal Food Safety Information. Additionally, healthcare facilities depend on accurate and precise thermometers throughout daily operations.

MWTX manufactures and calibrates a full range of liquid and glass thermometers and hydrometers that meet a range of temperature and gravity measurement needs. Re-calibration services are available by completing the Calibration Laboratory Order Form. (See available calibration services in the chart at the bottom of the page.) For details about thermometers and hydrometers, visit the Miller-Weber Products Page.
