This post is the first of the "Diagnosing liquid maldistribution inside packed beds" series.
A challenge to process engineers is diagnosing liquid maldistribution problems inside packed beds that can cause severe mass transfer efficiency loss. In industrial distillation columns, common examples of the cause of liquid maldistribution are design, manufacture or installation defects of distributors as well as damage, plugging and process disturbance of packed beds.
In this latest blog, we will explain using a case study approach how Tracerco's scanning technologies can be used to diagnose suspected maldistribution in packed beds.
The first step to determine liquid maldistribution in a packed column is to perform a Tracerco Tru-Grid™ Scan to provide an initial look at the liquid distribution in the packing. A Tru-Grid™ scan consists of four equal-distant chords, one through each quadrant of the tower. Under ideal conditions and uniform liquid loadings, each scan plot will overlay closely with all others.

Suspected maldistribution in packed beds
Detecting and identifying small leaks in heat exchangers can be an extremely difficult and time consuming task for many operators and plant personnel. Product quality, process efficiency and the time and cost associated with maintenance and potential shutdowns caused by a leaking vessel can have a significant and detrimental impact on production and process operating margins.

Radiation safety and source security is becoming an increasing concern across all market sectors, with the illegal possession and illicit movement of radioactive sources having potentially severe consequences to site workers and both national and global communities. A necessary precaution taken by numerous facilities to ensure source security is the use of fixed area radiation monitors which provide the dose rate levels of source storage bunkers and Non-Destructive Testing (NDT) radiography bays.

In the challenging market conditions that we face today, reducing lift costs is paramount. One area where this can be achieved is through stimulation optimisation, ensuring reduce spend on stimulation activities and maximum oil or gas flow for a particular field.
In this post we examine five steps to achieving savings of as much as 20% in reservoir stimulation costs by using accurate flow data to optimise stage stimulation in individual wells and development of unconventional fields.
This is based on our vast experience across numerous fields and the insights and figures are taken from real projects conducted over the last few years.

The use of radioactive sources in hospitals requires many safety measures to be implemented to ensure that workers and the general public are protected. Although there are a number of measures such as shielding, dose rate and contamination monitoring and personal dosimetry that can be used to record radiation exposure, a key method of ensuring the safety of nurses, doctors and patients, is the use of fixed area radiation monitors. Fixed area monitors use multiple detectors to provide the dose rate levels of iodine therapy centres, patient treatment rooms and nuclear medicine departments. Critical and potentially life saving information is provided as fixed area monitors incorporate 24/7 monitoring with an early warning alarm that inform patients and staff when dose rates exceed set alarm thresholds. This ensures that all radiation risks are managed safely which is key to safer working practices for all personnel working within a medical environment.
Counterfeiting, duty evasion and other forms of illicit trade are a substantial and growing problem across all market sectors, leading to increased calls for businesses to make use of highly secure product and brand authentication programmes.
Estimates of the global value of counterfeit and illicit product sales vary widely. As the trade is illegal, official records of sales are not published so estimates of the sales of counterfeiting differ significantly. However, the undisputable fact is that all the estimates come up with staggering numbers representing a significant proportion of the global economy. Current estimates range from around US$700 bn per year (Havoscope) to US$1.7 trillion (ICC). This totally unregulated trade impacts everyone; brand owners, governments, consumers and the environment.

Tracerco is tailoring our offering to meet the needs and challenges of our customers with five brand new tracer labs to analyse reservoir samples.
In this blog post we will dicuss the top five questions we are asked with regard to our subsea pipeline technologies, Discovery™ and Explorer™.
There are a number of problems that can cause a loss of efficiency and lead to loss of production in a distillation column, including tray damage, flooding, weeping, and foaming. Gamma scan technology available from Tracerco can be utilised to locate the origin and/or severity of these problems. A Tru-Scan™ across the active area of a fractionation tray can provide hydraulic conditions and/or mechanical status of the active area, such as weeping and tray froth heights. FrothView™, a new methodology developed by Tracerco, provides a quantitative analysis of tray capacity as the total froth height on a tray that is measured using Tracerco's new detector technology and software interpretation.
In this latest blog post we will discuss how a Tru-Scan™ and FrothView™ technology was used to provide the % tray space to show the amount or percentage of available tray spacing that is occupied by froth or aerated liquid. Knowledge of the actual process conditions inside a vessel, provides engineers with the ability to make process adjustments accordingly.
