Coke Drum

A Coke Drum is a type of pressure vessel that uses heat and pressure to refine complex hydrocarbons into lighter, more useful, products, such as gasoline, diesel, and jet fuel. Coke drums are an...
Coker Units

Coker Units or Cokers, are pieces of oil refinery processing equipment used to recover specific elements from process residues, tar pitch, and residual oils. The coking process involves what is known as cracking; where long chains...
Delayed Coker Unit (DCU)

A Delayed Coker Unit is a type of coker that utilizes multiple pairs of drums working in tandem, sometimes as many as eight at a time, to recover specific elements from feedstock residues, tar...
Downstream

The Oil and Gas industry is commonly divided into the three major sectors: Upstream, which includes oil and gas exploration and production;
Mechanical Integrity (MI)

Mechanical Integrity (MI) can be defined as the management of critical process equipment to ensure it is designed and installed correctly, and that it operates and is maintained properly (i.e. no leaks and all elements are fit for service). A mechanical integrity program should...
Reliability

Reliability is a special attribute that describes the dependability of a component. This means that the component consistently performs a desired function under certain conditions for a certain period of time in order to meet business goals and...

Heater Tube Inspection and Remaining Life Evaluation

May/June 2014 Inspectioneering Journal

The following interview with Rich Roberts provides answers to some of the questions our readers have about small, specially designed pigs carrying NDE technologies that can inspect nearly every area of a tube from the coils interior surface.
Heat Exchanger Tubular Inspection

July/August 2008 Inspectioneering Journal

This paper covers most of the common (and some not so common) types of NDE methods for heat exchanger (HX) tubular in-service inspections. In addition to noting some of the various advantages and limitations with these methods, the paper covers heat...
Inspection of Individual Serpentine Coils in Fired Heaters Connected to Common Headers

May/June 2013 Inspectioneering Journal

Refineries and chemical plants own and operate numerous process heaters (e.g. gas reformers, CCRs, etc.) as part of the standard assets throughout the facilities. Many heater coil configuration designs are flanged at both ends; however, there are...
Inspection of Heat Exchanger, Condenser & Fin Fan Coolers Tubes - An Update

May/June 2007 Inspectioneering Journal

Tube Inspection is a vital tool for the refining and petrochemical industries. Heat exchangers and condensers are designed to sustain 100% separation between the products in the tube (tube side) and the products in the vessel (shell side). A...
Recent Technological Advances in Ultrasonic-Based Intelligent Pig Technology for Fired Heater Coils

January/February 2010 Inspectioneering Journal

For years refinery and chemical plant operators have utilized ultrasonic-based intelligent pig technology to inspect coils in convection and radiant sections of fired heaters. This proven technology provides accurate inspection data which allows...

Quest Integrity’s Advanced Decoking & Cleanliness Verification (ADCV) empirically detects and measures internal fouling eliminating any uncertainties in coil cleanliness. This is accomplished using specialized ultrasonic-based technology, software, and proprietary cleaning methods. Refinery and Petrochemical owners decoke heaters to preserve the integrity of their tubes, improving throughput and operating efficiencies. When performing this type of standard maintenance activity, it is reasonable to expect solutions that do not diminish tube integrity and overall heater performance. By applying ADCV, this service allows benefits including:

Owner/operators are able to use data-driven solutions that can reduce decoking times
Reveal unexpected operational issues and validate cleaning efforts
Allowing assets to return to service faster
And with better operational assurances
