MOSCOW (MRC) -- Honeywell UOP selected
GEA Refrigeration Technologies’ oil & gas team to supply engineered
compression packages for a tail gas application at a refinery in Azerbaijan,
said Hydrocarbonprocessing.
Utilizing
GEA's most powerful screw compressor, the GEA model XH, the systems are designed
for a modernization program at the refinery.
GEA's tail gas packages were
selected for the project by Honeywell UOP as part of their Pressure Swing
Adsorption (PSA) technology to supply high-quality hydrogen for the
modernization of the Heydar Aliyev Oil Refinery (HAOR) in Baku, Azerbaijan. Pure
hydrogen is essential to the refining process, where it is used to decontaminate
oil and facilitate catalytic processes that produce clean-burning fuels,
including those that meet Euro V standards for vehicle emissions.
The PSA
technology will help Azerbaijan meet the growing domestic demand for
transportation fuels that meet the Euro V standards. Hydrogen technology is an
important element of modernization program that will help the refinery in
Azerbaijan to remain among the most advanced refineries in the region, further
improving environmental protection along with the quality of life in
Azerbaijan.
The modernization enables the refinery to process 7.5 million
metric tons per annum of crude oil blended from local sources. Hydrogen is key
in the refining process, being produced as a byproduct of refining and
intentionally from a steam methane reformer. Honeywell UOP's PSA technology
purifies this hydrogen so it essentially can be recycled into the refinery to
remove impurities and to perform catalytic processes that transform crude oil
into clean fuels and other products.
The purpose of these tail gas
compression units is to receive the tail gas – a gas mixture composition with up
to ~70% hydrogen – from the PSA System and keep stable pressure at the PSA
discharge. Received gas is compressed up to 6,7 bar(g) and then cooled down to
40°C in the after cooler before it is returned to the customer’s
system.
These units are based on an oil-flooded screw compressor and the
oil is separated from the tail gas into two oil separators (main and final) in
order to deliver the gas with less than 1 ppm of oil content. As an oil-flooded
screw compressor, the oil circuit is provided for lubricating the internal part
of the screw compressor. The oil circuit comprises two oil pumps (one in
standby), a pressure control valve to keep the oil
pressure constant and an electro-pneumatic three-way control valve to
maintain the oil flow to the compressor at a fixed temperature. The oil circuit
also comprises two oil coolers (one in standby) with a common inlet and outlet
line for the cooling water system. The discharged oil at high temperature,
recovered in the oil separator, is cooled down by using cooling water as a
medium.
All vessels and all heat exchangers are designed and manufactured
according to ASME (American Society of Mechanical Engineers) and TEMA R (Tubular
Exchanger Manufacturers Association). GEA also provided the personnel protection
with rock wool and aluminum and winterization of the entire oil
circuit.
As per MRC, Honeywell announced a
partnership with Princeps for petroleum refining supply chain solutions.
Honeywell’s expertise in oil and gas planning will add Princeps’ petroleum
solutions platform to its offerings to provide customers with industry-leading
insights in determining the most profitable ways to operate their
plants.
As MRC reported earlier,
in May, 2020, Honeywell announced that Enterprise Products Partners L.P. will
use Honeywell UOP’s C3 Oleflex technology in its second propane dehydrogenation
plant, called "PDH 2". Located near Mont Belvieu, Texas, PDH 2 will produce
750,000 metric tons per year of polymer-grade propylene as part of Enterprise’s
expansion of propylene manufacturing capacity.
Propylene is the main
feedstock for the production of polypropylene (PP).
According to MRC's ScanPlast report,
Russia's estimated PE consumption totalled 2,220,640 tonnes in 2020, up by 2%
year on year. Only shipments of low density polyethylene (LDPE) and high density
polyethylene (HDPE) increased. At the same time, polypropylene (PP) shipments to
the Russian market reached 1 240,000 tonnes in 2020 (calculated using the
formula: production, minus exports, plus imports, excluding producers'
inventories as of 1 January, 2020). Supply of exclusively PP random copolymer
increased. |
