July 2, 2018 | KBR SCORE™ Technology Selected for GS Caltex Grassroots Olefins Plant in South Korea
KBR, Inc. announced today that it has been awarded a contract to supply its proprietary SCORE™ Ethylene Technology to GS Caltex Corporation for a grassroots mixed feed cracker (MFC) for its project in Yeosu, South Korea. Under the terms of the contract, KBR will provide its innovative Selective Cracking Optimum Recovery (SCORE™) technology license and basic engineering design services for a 700 KTA ethylene mixed feed cracker to be built by GS Caltex, a company owned by GS Energy and U.S. based Chevron Corp. The new plant will use naphtha, liquefied petroleum gas and refinery off-gases as its main feedstocks. It will be constructed in the South Korean southern city of Yeosu where GS Caltex's 790,000 barrels-per-day refinery is located. The project will use KBR's highly selective SC-1 furnaces for the highest yield and flexibility. (Source)

29^th Aug 2018 | GS Caltex to Build Olefin Plant in Yeosu for 2.6 Tln Won
GS Caltex said on Aug. 7 (2018) that the company decided to build an olefin production facility capable of producing 700,000 tons of ethylene per year and 500,000 tons of polyethylene annually by investing about 2 trillion won ($1.8 billion) in a 430,000-square-meter site near its second plant in Yeosu, South Jeolla Province.

11^th Nov 2022 | GS Caltex completes construction of $2 billion petrochemicals manufacturing plant.
GS Caltex completed the construction of its 2.7-trillion-won ($2 billion) petrochemicals manufacturing plant in Yeosu, South Jeolla.
The newly-built production plant, a mixed feed cracker (MFC), will mainly produce olefins such as ethylene and polyethylene. Olefins are widely used as raw materials for plastics, rubbers and chemical products.
The MFC will annually produce 750,000 tons of ethylene, 500,000 tons of polyethylene, 410,000 tons of propylene, 240,000 tons of mixed C4 raffinate and 410,000 tons of pyrolysis gasoline, according to GS Caltex.
Unlike naphtha crackers, which uses only naphtha for petrochemicals production, MFCs can use not only naphtha but other feedstock such as liquid petroleum gas and refinery off-gas, which are crude refining byproducts. The facility can also produce hydrogen using naphtha and refinery off-gas, replacing the previously-used liquefied natural gas, and therefore cut carbon emissions by 76,000 tons a year, said GS Caltex.

4^th Jul 2024 | Korea’s GS Caltex to debottleneck Yeosu cracker in Sep
The cracker will undergo a turnaround and debottlenecking from 23 September to 25 November, according to sources at the company. GS Caltex's mixed-feed cracker currently has a nameplate capacity of 750,000 t/yr of ethylene and 410,000 t/yr of propylene. Its ethylene capacity will increase by 150,000 t/yr to 900,000 t/yr after the debottlenecking process, while propylene capacity will rise by 60,000 t/yr to 470,000 t/yr.
The debottlenecking process will also raise GS Caltex's crude C4s output from the existing 250,000 t/yr to 300,000 t/yr. The company now feeds its crude C4s to a 90,000 t/yr butadiene extraction unit, a joint venture (JV) plant between GS Caltex's parent company GS Energy and fellow producer Lotte Chemical.
GS Caltex also owns two polymers units at the same site — a 500,000 t/yr high density polyethylene (HDPE) and a 180,000 t/yr polypropylene (PP) plant. The PP unit takes in propylene from GS Caltex's existing refinery fluid catalytic crackers (FCC).
The debottlenecking will raise olefins output, resulting in a surplus of 400,000 t/yr of ethylene for domestic sales and exports after supplying its HDPE plant. The propylene surplus will be 800,000 t/yr after factoring in GS Caltex's 500,000 t/yr propylene output from existing FCCs and its PP consumption.
This will also mark the first turnaround of GS Caltex's cracker since it was commissioned in 2021. GS Caltex's mixed feed cracker can take in a combination of naphtha, liquefied petroleum gas and off-gas from its FCC.

Petrochemical Industry Going Global Alliance | November 9, 2024 10:50, via WeChat.

On July 6, 2023, with the 400,000 tons/year ethylbenzene-styrene unit producing qualified products, all units of the Anqing Petrochemical Refinery Conversion Plant Structural Adjustment Project were successfully started up safely and environmentally friendly at one time.

The project is led by a 3 million tons/year heavy oil catalytic cracking unit. By increasing the production of light olefins and aromatic raw materials to produce high-value-added chemical products, it effectively enhances the adaptability and flexibility of the company's production structure to changes in demand, and explores a development path for domestic refining companies to cope with overcapacity and achieve transformation and upgrading.

Among them, the 3 million tons/year heavy oil catalytic cracking unit is the world's first RTC process heavy oil catalytic cracking unit, and the 400,000 tons/year ethylbenzene-styrene unit is currently the largest dry gas-based ethylbenzene unit in China.

The heavy oil catalytic cracking unit of Anqing Petrochemical has been started-up

Seetao 2023-06-25 15:12

The heavy oil catalytic cracking unit of Anqing Petrochemical has a total of three main fan units, namely two main units K101A/B and one backup fan unit K102. After the backup fan is successfully started and the two units have completed the relevant air tightness and other related processes, the K102 unit will be shut down, and the two main fan units K101A/B will enter the ignition furnace heating stage. It is expected that the overall start-up process will continue for more than 10 days.

Anqing will stop operating its 1.4mn t/yr fluid catalytic cracker (FCC) and 700,000 t/yr deep catalytic cracking unit, which are located near a residential area, for environmental reasons. The project will involve adding a new 3mn t/yr DCC that will enable the refinery to process crude with a higher sulphur content of 1.5pc.

Anqing currently produces 30,000 t/yr of polypropylene, 100,000 t/yr of ethylbenzene and styrene and 210,000 t/yr of acrylonitrile, among other products. It will scale up output of these products through the upgrading project.

Sinopec's Anqing refinery shifts towards petrochemicals

PETROTHALIL Analytical Petrochemical News Agency | 2020/06/23 09:38:57

Work on the 11bn yuan ($1.5bn) project at Anqing in the central province of Anhui started in early May. A Yn6.6bn first phase aims to produce around 2mn t/yr of olefins and aromatics, including 150,000 t/yr of ethylene, 640,000 t/yr of propylene and 610,000 t/yr of aromatics products. Trial production is scheduled for late 2022. A second, Yn4.4bn phase will add another 650,000 t/yr of unspecified chemical output.

Refined product output will be cut by a third after the project is complete, with the gasoline yield rising at the expense of diesel. Anqing is also expanding its pipeline connections to replace fuel transportation by river. Sinopec opened an 88,000 b/d oil products pipeline linking Anqing to the cities of Hefei, Huainan, Bengbu and Fuyang in late 2016.

Anqing will stop operating its 1.4mn t/yr fluid catalytic cracker (FCC) and 700,000 t/yr deep catalytic cracking unit, which are located near a residential area, for environmental reasons. The project will involve adding a new 3mn t/yr DCC that will enable the refinery to process crude with a higher sulphur content of 1.5pc.

Anqing currently produces 30,000 t/yr of polypropylene, 100,000 t/yr of ethylbenzene and styrene and 210,000 t/yr of acrylonitrile, among other products. It will scale up output of these products through the upgrading project.

Picture: Indian subcontinent refineries, via ppPLUS

India’s dependence on imports to meet its requirements of basic petrochemicals, including polymers, is only expected to rise, despite projects – under implementation and on the drawing boards. This is partly because the historical baggage of poor capacity builds will take time to catch up with rising demand.

In the last few years, however, India’s public sector refiners have climbed on the petrochemicals bandwagon, seeking value-added outlets for refinery streams. They have invested in aromatics (for feeding the polyester value chain), propylene (for polypropylene, PP, and some other chemicals notably, oxo-alcohols and acrylate monomers), linear alkyl benzene (LAB), a key detergent raw material, and a few other projects. And more are to come in the near-term.

There are several commonalities amongst the firm projects. For one, the emphasis seems to be on building the C3 (propylene) value chain. This is not surprising as FCC propylene offers a simple, low-cost route to the olefin and one that can be conveniently retrofitted into existing refinery operations. There is also an overwhelming emphasis on PP production, which may not be wise, as it runs the risk of overbuild should demand growth not pan out as anticipated.

There are other propylene derivatives that can be considered, and these merit attention if not by the refiners themselves then by third party investors for whom it will be more worthwhile. Much will hinge on the commercials of the olefin supply arrangement, but such business models are widely followed, including here in India, let alone in other countries.

Importantly, the government needs to recognise that the chemical industry as a key enabler of modern living, and not a nuisance to be constrained through regulation and red-tape. The priority must be on developing well-developed clusters where not just the petrochemical industry, but also the broad chemical industry – including the fine and specialty chemical industries, wherein India’s competitiveness is well recognised – can locate and start operations in double-quick time. Clusters are efficient and safe locales where the industry can thrive, as several countries have amply shown.

India needs a much larger and more diversified chemical industry than it has now. The former it seems is happening. Not so sure of the latter. The herd mentality to investments needs to change. Those who have dared to do so – and there are a few examples – have been amply rewarded. More need to emulate, not imitate, them!
