HP Flashback: Operations, processes and safety evolve and advance: Excerpts from the 1930s

Nichols, Lee, Hydrocarbon Processing Staff

The following is a mixture of technical articles, columns and headlines published in the 1930s by The Refiner and Natural Gasoline Manufacturer, the forerunner to Hydrocarbon Processing.

Case study: Challenges in the selection of a helical baffled exchanger

In a greenfield project, a proprietary heat exchangera has been found to be preferable to conventional shell-and-tube (S&T) exchangers to optimize the total lifecycle cost (i.e., capital, operating, installation and maintenance costs).

Maximize value and successfully revamp a fired heater

Platvoet, E., XRG Technologies

Fired heaters are facing scrutiny because they contribute to the global emissions of carbon dioxide (CO2) and nitrogen oxides (NOx).

Gas-side fouling effects on transfer-line exchangers

Manenti, G., Alfa Laval Olmi SpA

Transfer-line exchangers (TLEs) are specific shell-and-tube heat exchangers installed out of hydrocarbons steam cracking furnaces for olefins production.

Bolting material bolts-up the exchanger design

Singla, P. K., Worley

Shell-and-tube heat exchangers use multiple girth flange joints based on their Tubular Exchangers Manufacturers Association (TEMA) type to assemble shell and tube sides.

Impact plant performance by improving the steam system

Walter, J. P., TLV Corp.

Petrochemical plants and refineries face production and profitability challenges on multiple fronts.

Process Controls, Instrumentation and Automation: Why it is time to move on from the thermowell

Thermowells are widely used in industrial applications for measuring temperature; however, with new, high-accuracy, non-invasive alternatives available, it is time to move on from thermowells and embrace more innovative measurement techniques.

Advanced methods for controlling boiler tube corrosion and fouling—Part 2

Kraetsch, K., Buecker, B., ChemTreat, Inc.

In Part 1 of this article, the authors covered techniques for minimizing corrosion and contaminant ingress from condensate return and feedwater to industrial steam generators.

H2O2 and its hydrocarbon nitridation/oxidation to produce caprolactam and propene oxide

Zong, B., Shi, Y., Sun, B., Sinopec

Traditional hydrocarbon nitridation and oxidation technologies, such as caprolactam (CPL) and propene oxide production technologies, present low atom utilization and serious environmental pollution problems.
