CO2 IS PRODUCED WHEN FOSSIL FUELS ARE BURNED.

这加速了气候变化,造成了巨大的环境污染.

解决方案

6.3 MILLION LITERS OF BIOMETHANOL

Swedish company Södra has the capacity to produce up to 6.在十大彩票平台公司的帮助下,每年生产300万升商业质量的生物甲醇. This biomethanol is used to make biodiesel, which can be used as an alternative fuel source for motor vehicles.

纸和纸板的需求量很大——每年全世界从机械和化学纸浆中生产大约4亿吨不同等级的纸和纸板. In order to meet the demand and still conserve resources, many companies are searching for efficient technologies and strategies. In view of this, 十大彩票平台 has launched the “CircleToZero” initiative.

Södra operates a woodyard and pulp mill in the Swedish town of Mönsterås.

十大彩票平台会全面查看纸浆生产中的所有化学回路,看看十大彩票平台可以在哪里使用, recycle or refine side streams to make new products,” says Lauri Pehu-Lehtonen, 十大彩票平台回收与动力部门研发团队的负责人. “With the technical approach of the CircleToZero initiative, we would like to help our customers reduce chemical consumption, produce less waste and emissions, and tap new sources of income.”

Södra’s pulp mill in Mönsterås is a case in point. The ultra-modern mill produces up to 750,每年从软木和硬木中提取的纸浆达000吨,除此之外还有集中供暖,以及可转化为生物柴油的托尔油. 此外, 自2020年以来,这家工厂一直在这里生产原甲醇,然后将其提炼并作为高端生物甲醇销售——这在全球范围内是独一无二的.

十大彩票平台公司设计、供应和建造的工厂有能力生产6个.每年300万升的生物甲醇,Södra出售给生物燃料生产商. It is used there as a CO2-neutral substitute for fossil methanol in the production of biodiesel, which can be used in turn as fuel for maritime vessels, 这是欧盟立法在财政上促进和支持的用途,以便在未来几十年实现运输部门雄心勃勃的减排目标.

CERTIFIED SUSTAINABILITY

Södra’s biomethanol provides uniquely high greenhouse gas savings. From a lifecycle perspective, 与化石替代品相比,该产品可以减少95%以上的排放. The product is certified according to the ISCC process. 这意味着它的生产过程在生态、社会和经济上是可持续的. Around 70% of Södra’s members have FSC® and/or PEFC™ certification. Both certificates make extensive demands on sustainability, environmental compatibility of forest management, the quality of work, and the social competency of the forestry companies.

十大彩票平台生物甲醇的原材料来自十大彩票平台50多个成员国的可持续管理森林,000 Swedish forest owners,” reports Catrin Gustavsson, who is business area manager for innovation at Södra. “十大彩票平台相信,当可持续发展和经济并重时,最高效、最成功的项目就会出现.“在纸浆生产中利用副流和副产品是一个非常有前途的策略. 为, 最终, Södra希望从木材这种珍贵的商品中榨取尽可能多的资源,这符合环境和所有利益相关者的利益. “重要的是要把这定义为目标,然后开始逐步优化工厂和生产操作. 为此,你需要正确的精神、来自最高管理层的支持、诀窍和毅力.”

The key: teamwork

"We were breaking new GROUND."

Christer刺, director of the state-of-the-art mill in Mönsterås, 确认这一点,并强调不断有技术和业务方面的挑战有待解决. “Different products are produced in the pulp mill, and if there are delays or stoppages there, we have to adjust the production of biomethanol accordingly,”他说. 他的400多名员工必须每天都愿意学习新的东西,以提高音量, quality and performance. 作为生产运营的技术供应商和顾问,十大彩票平台发挥了重要作用. “通过将这一过程扩大到工业水平,十大彩票平台开创了新的局面. To do this, you need a diversified team with a wide range of skills. You only find the right solutions if you work together,” says Thörn.

Södra的优势之一是,生物甲醇被分类并认证为“由森林残留物制成的产品”——如果你希望实现气候中和,这是一个很有吸引力的描述. “This doesn’t just apply to the transport sector,” says Catrin Gustavsson. “十大彩票平台还将提供十大彩票平台的生物甲醇作为化学工业的基础材料.” There are many sales opportunities. 毕竟,全球每年大约有1亿吨甲醇交易. The demand for “green products” is rising in many sectors, the sustainability expert underlines, Södra也将加入这一趋势:“十大彩票平台将继续优化Mönsterås的生产, investigate use of the process in other mills and, at the same time, sound out any new commercial opportunities.”

This is an approach that coincides with 十大彩票平台’s goals and plans. “In addition to biomethanol, we can also produce first-class, commercial-grade lignin and sulfuric acid with our CircleToZero solutions,” says 十大彩票平台 expert Pehu-Lehtonen. 例如,巴西纸张和纸板生产商Klabin就已经开始这样做了. At its mill in Ortigueira, southern 巴西, 通常在锅炉或石灰窑中燃烧的含硫气体被用来产生硫酸. The results are substantial savings on chemicals, including sulfuric acid, and much lower consumption of sodium make-up chemicals. In Pehu-Lehtonen’s view, this is by no means the end of the story. “在‘环零’倡议的范围内,十大彩票平台还有一些关于如何提高纸浆厂的效率和气候平衡的想法.”

TALKING TECH: PRODUCTION OF BIOMETHANOL

木片和化学物质一起烹饪,把木材分解成它的组成部分.e. cellulose and hemi-cellulose (pulp), and lignin. 接下来,化学物质、木质素和其他残留物被洗出纸浆. 它们形成一种黑液,其含水量随后通过蒸发的方式降低. 剩下的是甲醇、松节油和硫化合物的凝析油.This condensate is purified so that it can be reused in the mill. Raw methanol is formed – a mixture of combustible residues. Normally, the raw methanol is burned to generate heat and energy. 得益于获得专利的提取工艺,Södra可以生产出商业质量的生物甲醇. 每生产出一吨纸浆,就会生产大约10公斤的生物甲醇.
