Making ethanol more efficiently - INEOS

Continuously improving efficiency and reducing carbon emissions is standard practice across INEOS. We know that a lot of small improvements will amount to a big difference, said the company.

On paper, converting ethylene to ethanol is relatively simple - just add water. In practice, the industrial chemistry that underlies the process is somewhat more complex, requiring large amounts of water, steam and energy. But here’s how our team in Grangemouth recently both improved plant efficiency and made a major cut to emissions.

The INEOS Grangemouth ethanol plant was commissioned in 1983 and has been significantly upgraded over the last 5 years to improve performance and reliability. The production process requires an excess amount of water for the reaction to take place, but needs the right balance be struck. Using more water in the reaction will decrease impurities, while further down the line more steam is needed to purify and ‘dry’ the product by boiling off the water – a costly process. Conversely, too little water increases production of unwanted by-products and not enough ethylene is converted into ethanol.

The technical team decided to review the entire manufacturing process. Was there a way to be more efficient, reducing water and steam usage, with a reduction in carbon emissions per tonne of product too.

Determined to come up with a solution, they carefully examined every aspect of the manufacturing process alongside the operations team, from the temperature the reactants enter the reactors to the management of energy and steam across the asset.

We remind, INEOS has completed the purchase of Mitsui Phenols Singapore in a USD330m deal, giving the UK-based firm over 1m tonnes/year of additional Asia production capacity. Based on Jurong Island, Singapore, the entire asset base of the Mitsui subsidiary will be transferred to INEOS. The business has a production capacity of 410,000 tonnes/year of cumene, 310,000 tonne/year of phenol and 185,000 tonnes/year of acetone.

Two Chinese polyester fiber makers are seeking Beijing's approval to build a USD10-B refinery and petrochemical complex in Indonesia, sources with direct knowledge of the matter told Reuters.

The move comes as China ramps up talks on mega investments in Southeast Asia as part of President Xi Jinping's Belt and Road Initiative, and as Beijing limits approvals for new domestic refineries to cut carbon emissions and a fuel supply overhang.

East China-based Tongkun Group and Xinfengming Group are planning a refinery-petrochemical complex in North Kalimantan province on Borneo Island, three sources said, to produce feedstocks for chemical fiber. Led by Tongkun, the proposed petrochemical complex would include a 200,000 barrels-per-day refinery and an 800,000 ton per year ethylene unit, which could be expanded in the future, said two of the sources.

The project would be part of a planned industrial park in North Kalimantan where companies broke ground on a USD2.6-B hydropower project last month to attract aluminum, battery and electric vehicle manufacturers.Tongkun has begun feasibility studies for the project, which would partly make paraxylene for its growing production of purified terephthalic acid (PTA) in China, a feedstock for polyester fiber, two sources said.

It is also seeking approval from China's state planner, the National Development and Reform Commission (NDRC), they said. A Tongkun investor relations official said the Indonesia refinery project is at an early planning stage but declined further comment. A Xinfengming investor relations official declined to comment.

We remind, in November, top executives of the two Chinese companies briefed Indonesian President Joko Widodo on their investment plans in North Kalimantan on the sidelines of the G20 summit in Bali, according to a post dated Nov. 18 on Tongkun's official WeChat account that gave few details.

GAIL Gas Limited has announced a reduction in its Domestic PNG prices by Rs. 7 per SCM in Bengaluru and Dakshin Kannada and Rs. 6 per SCM in all its other Geographical areas. The new effective Domestic PNG Prices is Rs 52.50 per SCM in Dewas, Meerut, Sonipat, Taj Trapezium Zone, Raisen, Mirzapur, Dhanbad, Adityapur and Rourkela and Rs 51.50 per SCM for Bengaluru & Dakshin Kannada.

Similarly, CNG Prices are also reduced by Rs 7 per kg in Karnataka GAs and Sonipat and Rs 6 per kg in rest of the GAs and by New CNG Price is Rs 85 per kg for Meerut & Sonipat; Rs 92 per Kg for Dewas, Taj Trapezium Zone & Dehradun; Rs.82.50 per kg for Bengaluru & Dakshin Kannada; Rs 87 per kg for Mirzapur, Rs 91 per kg for Raisen, Dhanbad, Adityapur, Puri and Rourkela.

The new guidelines aim to establish a stable pricing regime for domestic gas consumers while providing sufficient protection to producers from adverse market fluctuations, along with incentives to user industries and CGD sector. It will accelerate the expansion of CNG & PNG as a preferred fuel, and will also contribute to reducing the carbon footprint.

GAIL Gas Limited operates in 16 geographical areas across the country and is working towards gas based economy in India.

We remind, Government of India and India's largest gas utility and gas supply company, through a wholly owned MOL subsidiary signed a time charter contract for a newbuilding LNG carrier and a joint ownership of an existing LNG carrier. The new building vessel will be the second MOL Group LNG carrier serving GAIL; the parties signed a contract for the first vessel in 2019. The existing vessel still has been chartered to GAIL through a wholly owned MOL subsidiary from 2021 and even now, MOL’s shipping service is highly regarded by GAIL.

Teijin Frontier Co., Ltd., the Teijin Group’s fibers and products converting company, announced it has developed a new foreign material removal technology to eliminate polyurethane (PU) elastomer fiber from discarded polyester apparel, said the company.

The technology features a new processing agent used during the pretreatment phase of the chemical recycling process, which helps improve the quality of the recycled polyester fiber that is derived from clothing containing PU elastomer fiber. In addition to removing the PU elastomer fiber, the new technology eliminates foreign materials such as dyes, and helps to omit the decolorization process of polyester fiber. Teijin Frontier has been conducting tests of this new technology since October 2022 for practical use.

Guided by THINK ECO environmental strategy, Teijin Frontier is striving to achieve ambitious sustainability goals by developing advanced technologies that support recycling and enhance the value of environmentally responsible materials. As part of its initiative focused on polyester fiber, the company is working with the supply chain to establish a comprehensive ecosystem spanning apparel collection, sorting and recycling. Teijin Frontier is confident that its new foreign material removal method can help expand the scope of fiber-to-fiber recycling and contribute to a zero-waste society.

The new foreign material removal technology swells the PU elastomer fiber, breaks the chemical bonds and dissolves them with the new processing agent. Simultaneously, the agent eliminates foreign substances including dyes to optimize decolorization of the polyester fiber. For system cost control and environmental load reduction, the processing agent can be collected and reused. Recycled polyester materials generated by this method can be used in the existing chemical recycling process.

Stretchable polyester clothing that contains PU elastomer fiber is becoming popular as the demand in the industry for quick-drying, wrinkle-resistant, and comfortable-to-wear is increasing along with the trend to casual wear. However, as conventional chemical recycling technology for polyester assumes 100% polyester products, the quality of the recycled product deteriorates when PU elastomer fibers are included. Therefore, it is important to remove PU elastomer fiber from discarded polyester clothing.

We remind, Teijin said that it has started producing and marketing biomass-based polycarbonate (PC) resin products at the company's Matsuyama and Mihara production sites. "Beginning on 30 January, Teijin... has started producing and marketing biomass PC resin products containing bisphenol A (BPA) made from biomass naphtha that was tracked with the mass-balance approach as well as the conventional PC resin products using petroleum-derived raw materials," the company said in a statement.
