Heat Tracing Cable for Maintaining Critical Petrochemical Viscosity

Heat Tracing Cable

Petrochemicals are petroleum-derived chemical materials. Many of these chemicals come from resources like coal , natural gas, corn or even sugar cane. The two most popular petrochemical groups are olefins and aromatics, the building blocks used to generate a wide variety of daily materials such as solvents, detergents, adhesives, plastics, resins, fibers, elastomers, lubricants and gels. Most chemicals and gasses move through pipelines and are stored in tanks in petrochemical plants. Petroleum-based chemicals often thicken and flow poorly at lower temperatures. If petrochemicals are not maintained at the correct temperature, viscosity problems cause the liquids to flow inefficiently and can starve or clog production lines.

To maintain the high temperatures needed for petrochemical output, install constant-wattage heating cable along piping. Constant wattage heating cable is a versatile heating cable mounted on the outside of pipes and valves (heat tracing) and capable of sustaining temperatures up to 260 ° C (500 ° F). Constant wattage heating cable is also used to heat long runs of piping systems up to several hundred feet. Heating cables are ideal for outdoor use and are FM-approved for hazardous locations. Insulation is advised to improve heat and energy efficiency and a temperature controller is needed to monitor constant wattage heating cable. On almost all pipe heating applications, constant-wattage heating cable may be used. Common uses  include freeze protection, viscosity reduction, condensation prevention, and more.

Self-regulating heating cable is another way to maintain lower temperature systems. This form of heating cable automatically changes its heat output depending on ambient conditions and never exceeds a fixed temperature, normally 149 ° F (65 ° C). Low temperature heating cable will reach 248 ° F (120 ° C). Typical uses for self-regulating heating cable are low-temperature repair and freezing applications.

Special Design Magnetic Level Gauge Overcomes Slug Catcher Level Challenges

Slugcatcher level control
In normal pipeline applications where gas and liquid moves together, gravity pushes the liquid component to the bottom of the pipe and the gas component flows above. In some situations however, the gas and liquid may combine and form a plug. In the pipeline industry these plugs are referred to as "slugs". Slugs can cause problems at the pipeline outlet as they can easily overload a plant's ability to handle the liquid or gas flow safely or efficiently.

In order to avoid problems with slugs, the use of a "slug catcher" is deployed. Located between the process equipment and the pipeline outlet, slug catchers are vessels with enough holding capacity to hold a slug as they travel down the pipeline. The additional holding capacity allows for the gradual draining of liquids from the system to avoid system overload.

MONITORING SLUG CATCHER LEVEL

The biggest problem for slug catcher applications is solids accumulation. The build-up occurs naturally during normal operations. Solids will continue to accumulate until they are physically removed.

Magnetic level gaugeSlugcatcherSolids accumulate in the piping around the vessel/drum. This can cause operational failure as the piping can get congested. Solids build-up on sight glasses is very dangerous because the sight glass is a critical component to the operation of a slug catcher.
The most common liquids measured are hydrocarbons and water. Once the sight glass accumulates solids or discoloration on the viewing window, the liquids may not be visible at all.

MAGNETIC LEVEL GAUGE

To overcome all of the challenges that slug catcher applications pose for safe and reliable level monitoring, Jogler engineers created the following design that has been implemented and proven over many years of operation:

INDIRECT LEVEL MEASUREMENT 
Unlike a sight glass, a magnetic level gauge does not include direct sight of the liquid. Instead, the level is magnetically conveyed via the interaction of flags in the external scale assembly and magnets in the float. This makes it impossible for the glass to become clogged or dirty. Therefore, a magnetic level gauge offers constant, unimpeded liquid level viewing that will not deteriorate with any solids accumulation.

GUIDE RODS
To prevent solids from interfering with proper operation of the float, the chamber is made from a 3” pipe with a 2” or 2.5” float and guide rods (other configurations available). This allows space for the solids to accumulate without interfering with the float traveling.

COATING
To help avoid buildup, the float and internal chamber can be coated with various products, such as Teflon S, to prevent fouling buildup on the float. If buildup can occur on the float, the weight of the float will increase give false low level readings.

CUSTOM FLOATS
An important part of the function of a magnetic level gauge is the design of the internal float. Floats can be engineered to handle various liquids, including extremely light hydro-carbons. To compensate for potential solids build-up, extra buoyancy can be included in the design of a float to ensure it can power through the solids without hanging up.

MAGNETIC PARTICLE TRAPS
In some slug catcher applications, iron sulfides and other ferromagnetic particles may be present. These magnetic particles present a risk to the long-term operation of the float, accumulating on the float’s magnets. This can increase the weight of the float causing false low level readings and can even build up to the point where the float sinks or gets stuck. To eliminate these risks, a magnetic particle trap can be installed on one or more of the process connections. The magnetic particle trap consists of high strength super-magnets that are placed in the flow path to the magnetic level gauge. These magnets collect any magnetic particles that can make it to the chamber to protect against build-up on the float. The magnetic particle trap is designed  easily be removed from the process connections so it can be periodically cleaned.

HEAT TRACING / INSULATION
In applications where process liquid in the slug catcher can be viscous, factory-installed heat tracing and insulation can be used to decrease the liquid viscosity. This will eliminate situations where the float will be sluggish to react to changing liquid levels or even freeze up entirely. Self-regulating electric heat trace cable provides a reliable heat tracing solution that is customizable to available power connections (typically 120VAC or 240VAC), process temperature, and minimum ambient temperature.

Continuous, Real-time Measurement for Full Visibility of Total Organic Carbon (TOC) in Pure and Ultra-Pure Water Systems

At-line batch method of monitoring total organic carbon (TOC), which takes measurements at set intervals, is the equivalent of taking snapshots of information. The gaps between measurement intervals could easily miss a critical event, whereas on-line, continuous TOC monitoring done by the Mettler Toledo 6000TOCi total organic carbon analyzer captures any-and-all excursions in real-time.

Monitoring total organic carbon levels is critical to meeting internal water quality specifications and global pharmacopeia regulatory requirements. Missing an increase in TOC levels can put you at risk of contaminating your water system, which in turn could affect production and potentially lead to an out-of-spec event or product recall.

Most TOC analyzers on the market offer at-line batch or non-continuous methods of total organic carbon measurement, which limits TOC data collection to every 6-12 minutes. But much can happen in six minutes.  When you are subject to an audit or have a quality problem, how are you sure that you did not experience a problematic TOC excursion between batch samples?

The 6000TOCi analyzer’s true continuous measurement along with its comprehensive record keeping and advanced diagnostics provide audit-ready TOC compliance and complete control of your water system.
