refinery. The project has been delayed due to budget cuts but will
still be built.
November, 2009 - International
patents for two recent U.S. nitrogen rejection patents are being
July, 2009 - AET was awarded a
U.S. Patent for nitrogen rejection using combined internal and external
solvents and improved controls.
- AET was awarded a contract
for expansion of the LPG Technology Package for Middle Eastern refinery
initially awarded in July, 2007. The design is now being upgraded to
remove 1900 barrels of LPG from 11 MMscfd of gas.
- AET was awarded a U.S. Patent
for removal of diamondoids from feed gas entering an AET Process NRU.
Diamondoids are a C-10 caged hydrocarbon molecule which will change from
vapor directly to solid crystalline formations with reduction in
temperature as occurs during initial cooling of most nitrogen rejection
processes including the AET Process NRU. The solidified diamondoids will
plug most pieces of process equipment if they are not successfully
- HNNG Development, LLC
announced initial successful operation of the Resource Energy
Technologies, LLC Nitrogen Rejection Unit in Kentucky. Initial rate is 2
MMscfd. Gas rate will increase to 5 MMscfd as additional wells are
- AET was awarded a U.S. Patent
for nitrogen rejection from natural gas using a cryogenic adaptation of
the AET Process absorption NRU. Additional filings in foreign countries
- AET was awarded LPG
Technology Package for U.S. Gulf Coast refinery. LPG recovery of 4000
barrels per day is expected from approximately 19 MMscfd of gas.
- AET was awarded a technical
support contract for evaluation of refrigeration and turbo-expander
technologies for use in a large LPG recovery plant for North Africa.
Contract work was accomplished through August, 2008.
– HNNG Development,
LLC announced initial successful operation of the Oso Oil & Gas
Properties, LLC nitrogen rejection unit in Utah. Initial rate is 2
MMscfd. The facility is expected to operate for several months at this
rate and then shut down while the current coal seam is abandoned and
machinery is moved to a new coal seam for restart in 2008.
July, 2007 -
AET was awarded LPG Technology Package for Middle
Eastern refinery. LPG recovery of 1300 barrels per day is expected
from the gas rate of 4.2 MMscfd.
June 4, 2007 - Oil & Gas Journal printed an article in this
week's edition titled "Saudi Aramco installs new LPG recovery unit at
Yanbu' Refinery" based on a presentation at the American Institute of
Chemical Engineers Spring National Meeting April 22 - 27, 2007, Houston.
April 23, 2007 - Saleh M. Al-Shahrani,
Yanbu' Refinery, Saudi Aramco, Saudi Arabia and Yuv R. Mehra, Process &
Control Systems, Saudi Aramco, Saudi Arabia presented a paper titled
"Start-up Experience for Value Recovery from CCR Net Gas at Yanbu'
Refinery", © Copyright 2007, Saudi Aramco, at the 2007 Spring Meeting of the American Institute of
Chemical Engineers (AIChE).
Yanbu' Refinery Department (YR) recently converted its Semi-Regenerative
Platformer unit to UOP licensed Continuous Catalytic Regenerative (CCR)
Platforming process. To recover value from CCR net gas, an LPG
Recovery Unit utilizing a new-to-Saudi Aramco technology was installed to
maximize LPG recovery and to increase the hydrogen purity of the net gas
for use in the new Diesel Hydro-Treater unit. This paper will
describe how the enhanced absorption process was incorporated at YR to
complement the existing Saturate Gas Conditioning Unit, and share the
experience with the start-up and operations of the LPG Recovery Unit.
The recovered, higher-value LPG is separated in the existing debutanizer
column. A new three-stage propane refrigeration system is used to
chill the CCR net gas to maximize LPG recovery.
February 13, 2007 -
Resource Energy Technologies, LLC ("RET") has signed a lease agreement
with HNNG Development, LLC for an AET Process® Nitrogen Rejection Unit ("NRU")
that will be deployed on RET's Park City Project in Edmonson County,
Kentucky, USA. The natural gas to be produced by RET in Edmonson
County, up to 5 MMCSFD, has an especially high nitrogen content of 17.5%.
The NRU is expected to become operational in July 2007.
January 31, 2007 -
Oso Oil & Gas Properties, LLC has signed a lease agreement with HNNG
Development, LLC for an AET Process Nitrogen Rejection Unit ("NRU") to
process natural gas from a coal mine near Price in Carbon County, Utah,
USA. The NRU, which is expected to become operational in the second
quarter of 2007, will process 1.5 - 8 MMSCFD of coal mine gas containing
December 22, 2006 - Gateway Energy Corporation today announced that it sold to HNNG Development, LLC ("HNNG")
its co-exclusive license in the United States, involving certain rights
to the AET patented nitrogen rejection process. As a consequence,
HNNG now has an exclusive license in all of North America and certain
rights in a number of foreign countries outside of North America to the
AET Process technology for nitrogen rejection.
December 19, 2006 - HNNG Development,
LLC, the licensee for AET Process technology for nitrogen rejection,
announces the beginning of the start-up phase of its first unit on Agape
