One Minute Process Engineering: Pipeline hydraulic calculation

Challenge

Are you frustrated with pipeline hydraulic calculations? Do you find it tedious to extract route data from a KML file and manually import it into a process simulator? What if I told you all of this could be done in just one minute?

Minimum Wall Thickness for Supercritical CO2 Pipeline

Challenge

Determining the minimum wall thickness for supercritical CO₂ pipelines requires consideration of multiple factors: internal design pressure, ductile fracture arrest, and dynamic pressure surges. While the design thickness for internal pressure can be readily calculated using ASME B31.4, the impacts of ductile fracture and surge pressures (similar to water hammer in liquid pipelines) are often discussed but seldom addressed in practical wall-thickness calculations.

What Can AI Do for Engineers? 

AI offers numerous benefits to engineers, but there’s a catch—it can hallucinate. How can you ensure that the answers provided by AI are accurate and reliable? Do you want to cross-check the references AI uses?

One effective way to leverage AI is by providing it with your own trusted data, ensuring that responses are based on verified sources. Let’s explore how I use Google Vertex AI to achieve this.

How is ammonia produced by Haber Process?

 Do you think Ammonia is part of Energy Transition, just like hydrogen? I think the answer is yes. Do you ever wonder how ammonia is produced? The most widely used technology by the industry is called Haber Process.

Introduction to Polymer Electrolyte Membrane PEM Electrolyzer

 Do you ever wonder how a hydrogen electrolyzer works? The idea is to split water into hydrogen and oxygen, using electricity. In this diagram, water is fed into the electrolyzer, after being pumped and cooled. Then, at the anode site, oxygen is produced and separated out in the Oxygen/water separator. While at the cathode side, hydrogen is produced. The high pressure hydrogen is separated out in the high pressure separator. After a pressure reduction valve, additional low pressure hydrogen is produced and the water is recycled back to the oxygen/water separator.

4 Mistakes to Avoid in Your Hydrogen Liquefaction Process Design

Hydrogen is going to be part of energy transition. Hydrogen liquefaction is going to be part of hydrogen value chain.

Are you ready to liquefy hydrogen? Before you start, you might want to avoid four (4) mistakes in your process design.

One Minute Process Engineering: Generate an Air Cooler Datasheet from Hysys, ProMax and Unisim

 Process engineers use different simulation software, such as Hysys, ProMax and Unisim. We also spend lots of time on extracting data from the simulation software to create process data sheets. Do you ever dream to create process datasheets from various simulation software in just one minute?

Hydrogen Liquefier with Helium Brayton Cycle and Liquid Nitrogen

Do you ever wonder how hydrogen can be liquefied? Hydrogen is the first element in the Periodic Table, but it has the second lowest boiling point temperature of -423 F. Do you ever wonder who has the lowest boiling point temperature? The answer is Helium, the 2nd element in the Periodic Table. How about the third and the fourth lowest boiling point? They are Neon and Nitrogen. Because of the low boiling temperature, so Helium, Neon and Nitrogen are commonly used to liquefy hydrogen. In today's video, a helium Brayton cycle and liquid nitrogen are used to liquefy hydrogen.

Use Steam Methane Reformer SMR to Produce Hydrogen

Introduction

Hydrogen is becoming a hotter and hotter topic. Do you know how hydrogen is produced? One popular method to produce hydrogen is through a steam methane reforming process.

Overview

Generally speaking, there are 6 process modules to produce hydrogen. First methane and steam react in the heating & reaction module, then it is cooled to ambient temperature before sending to a Pressure Swing Adsorption or PSA module to get the pure hydrogen. The final step is to compress hydrogen to the required pressure. Along with the 4 main process modules, we also need to have a steam module to produce steam and a flue gas module to provide all the heat needed in the process.

Methane feed is first split to 2 parts. The major part will be converted to hydrogen and the other part will be burned to provide the heat required. I will first go through the 4 main process modules and then come back to the 2 utility modules.

Guofu developed a method to find actual PSV choke pressure

Based on the easier two phase PRV method developed by Guofu, a new method is further developed to capture the actual PSV choke pressure for single phase, two phase, and super-critical conditions, instead of the ideal choke pressure. This presentation was delivered on DIERS meeting in Houston on 5/7/2018

Guofu just presented and published a paper on two-phase PRV on Global Congress of Process Safety conference in Orlando. This newly proposed method generates identical results as API 520 Homogeneous Direct Integration (HDI) method, but it is much easier than API when it is put into practice by engineers.
