Guofu is presenting a poster in Aspentech Optimize 2019 conference

Guofu is presenting a poster in Aspentech Optimize 2019 conference in Houston in May 2019. Come to the poster to check it out how Guofu utilizes Aspentech Optimizer to optimize capital cost, operational cost and revenue from products sold, for a RSV gas processing cryo plant.

What does a true standard condensate stabilizer look like?

Do you really have a true standard plant?

Do you have a standard plant? Many of us probably say yes.

Do you really have a standard plant? Only some of us might say yes with hesitation.

Do you really have a true standard plant? Only very few of us will say yes with confidence.

The reason why you don't have a standard plant

The reason why only very few of us have a true standard plant is that making plants standard is really, really, really hard. Many of us fail to answer the ultimate question: what's the output with the customer's particular input if they decide to choose your standard plant? We know the performance and the utility requirement at the design conditions of the standard plant, but how about the off-design conditions with a given set of existing equipment? In this video, you will learn what a true standard condensate stabilizer looks like.

Introduction to double-column Nitrogen Rejection Unit NRU

Introduction

It is estimated that 25% of the United States natural gas reserves contain unacceptably large quantities of nitrogen. Nitrogen is inert and lowers the BTU value of natural gas. It also takes up capacity in pipelines that could be used for valuable methane. Thus, nitrogen needs to be rejected from the gas through a Nitrogen Rejection Unit NRU. Typically, the feed to nitrogen rejection unit comes from the top of the DeMethanizer column of a cryogenic NGL recovery unit.

How Do You Control Your Gas Processing Mechanically Refrigerated Unit (MRU)?

Are you confident with your process control?

You modeled a steady state mechanically refrigerated gas processing unit, and then you created P&ID by adding all the control logics. Are you confident your closed refrigeration loop is going to work as you expect?

Dynamic Simulation is the solution.

The best way to verify your control logic is to build a dynamic simulation. This particular model is built in VMGSim Dynamic.

Is Your Slug Catcher Big Enough for Pipeline Pigging?

The Challenge

Pipeline pigging and slug catcher modeling have been a very difficult challenge for long long time. Now thanks to VMG, we can model pipeline pigging very easily in VMG Dynamic Simulation.

Do You Test Process Control and Cause & Effect via Dynamic Simulation?

Problems with Steady State Simulation

Steady state simulation is very good for designing a plant. However, when it comes to operation, there are so many questions a steady state simulation simply can't answer. Two typical questions are:

• Is my process control going to work?
• Does my cause and effect diagram really prevent me from any danger?

An introduction to modeling GSP gas processing plants in ProMax

There are generally three kinds of gas processing plants to get Natural Gas Liquid NGL from natural gas. The first kind is the J-T plant, which is suitable for high pressure and rich gas. The second kind is the Mechanically Refrigerated Unit MRU. The third kind is called a "Cryo" plants, which utilize cryogenic turbo-expander to extract NGL from very lean natural gas. One common process of cryogenic plants is Gas Subcooled Process, GSP, which was patented by Ortloff Engineer, LTD in the late 1970's. This video will explain how you can model GSP in ProMax.

Guofu completed ProMax Gas Processing Simulation Training

Guofu completed ProMax Level 2 Gas Processing Training on 18 September 2014. ProMax is a chemical process simulation software widely used in the Mid-Stream natural Gas Processing and Gas Treatment industry.
