Dear All,
Could any one suggest me the names of the Licensor for the Ethane Extraction From LNG. I was just searching on the internet but I found only one result and i.e. Cryomax Process by Technip. But the problem is that they don't have any plant as on today. So I am in the lookout of the licensor who has the running plant for the ethane extraction from LNG.
If anyone could tell something about the technology I will be thankful for him/her.
Thanks in advance.

Hello Padmakar,

I'd suggest you to go in other-way-around: look for experienced consultancy companies, and ask for their assistance in providing services for evaluation and selection of optimum technology for economic and efficient C2 extraction. GPSA book contains a lot of good references. Also, if you can reach Hydrocarbon Processing file for Gas Processors licensed technologies, that would be of big help. This file is copyrighted and I cannot upload it.

Hi Padmakar,

I don't know the name of EPC firm for extraction of Ethane from LNG. But one of the my previous employer they used to extract C2/C3 from Gas using technology supplied by Samsung Heavy Industries.

You may contact them if interested.

Dear,

I have checked with HP gas Processes but but I didn't find the process for Ethane Extraction from LNG. My concern is to extract ethane from the Methane rich stream of the de-methanize o/h stream which contains 7-8 % ethane. Anyways thanks for your suggestion.

[Zauberberg]

I'd suggest you to visit licensor's websites (there is a plenty of C2 recovery technologies nowadays).
And go to River City Engineering as well - they would be glad to offer you professional assistance.

Best regards,

Padmaker,

Technip has many references in Cryomax process...One of those is OTWAY plant in Australia which involve C3 recovery. The owner is WOODSIDE with SHELL is part of the owner...

If you talk to the Business development section, i am certain that they will advise you more reference.

Dear Joe and Zauberberg,
Thanks for your comments and help. But still I didn't get the solution for the problem. Ethane recovery in the NGL fractionation train i.e. by de-ethanizer is possible but I want to extract ethane from the Demethanizer overhead stream i.e. the LNG rich stream. The ethane content is 7-9 % which I want to recover for to compansate the ethane requirement for Cracker.

Padmakar,

The Cryomax MRE and Fluor TCHAP may be part of you solution.

I think there are many informations required to determine a proper solution for you query and it could form a concept studies by itself.

Dear Joe,
Here is the link for the cromax process by Technip,

Actually they have developed the technology and I had simulations of the same for my client here. But Just I was checking for this process of Technip but I didn't find. Could anyone give me reference of the Plant where they extract ethane from the LNG as this is the only way to get the information. Thanks indeed.

I know of the firm that Zauberberg describes in one of his literature. They are located on the 8th floor while my company is located on the 2nd, 3rd, & 5th floor of the same building here in Houston:

They have a very impressive list of clients - both domestic and international.

Padmakar,


Let me know if you still need help.
I assume you need to recover ethane from de-emthanizer OVHD. If you have the case on Hysys, just send it or send PFD and any process data

Hello,
The topic is almost more than three years old now. But I am still interested to know how to recover C2 fraction from de-methanizer overhead C1 rich stream. I came across the technology by Technip but was not commercialized till that time and they have proposed the scheme to my clinet which I was validating with Hysys and back up calculations. I will definately send you the file on your mail. And if possible the feedback from client, about the status of the project. Thanks indeed.

[NGL Licensor]

Recovery from Dec1 OVHD should be straight forward. However the composition, conditions and presence of CO2 will have an impact on the technology selected. Let us review the scheme and will start from this end.

Awaiting your e-mail.

My Regards
