Work has resumed fully at the Xin Tian Coal Chemical’s project for the deep processing of heavy aromatics and polyhydrocarbons / Source: Yaha Coal Chemicals Date: 2020-09-01 Clicks: 14 On August 30, work resumed in full at Xin Tian Coal Chemical’s project for the deep processing of heavy aromatics and polyhydrocarbons. After completing the verification tasks prior to concrete pouring, at the command of the relevant responsible person, the concrete mixer trucks arrived on site to start pile foundation construction, and the deep processing project for heavy aromatic hydrocarbons and polyhydrocarbons resumed operations officially. The heavy aromatic hydrocarbons and polyhydrocarbon deep processing project is a downstream technical upgrade project for the coal-to-natural gas project of Xintian Coal Chemical Industry, with a construction capacity of 200,000 tons per year. The project mainly includes a distillation unit, a finished product storage area, oil loading facilities, and a ground scale system, with completion scheduled by the end of April 2021. The project’s groundbreaking ceremony was held on May 28, and the piling contractors arrived at the site at the end of June; however, due to the impact of the pandemic, construction work on site was halted on July 26. This project is one of the key investment projects in Ili Prefecture and the group company for the year 2020. To advance the project’s progress, during the pandemic, the company’s project management department assigned dedicated personnel to oversee the project and work together with the general contractor on the preliminary tasks related to it. During the pandemic, with the cooperation of various parties, the project completed the review of technical documents for mechanical and electrical equipment, instrument control data sheets, system integration, project construction organization plans, and preliminary construction strategies, ensuring that the project progressed in an orderly manner while efforts were made to combat the pandemic. With the increasing **environmental regulations**, the heavy aromatics produced as a by-product in the coal-to-natural gas production process have been classified as hazardous waste under the **List of Hazardous Wastes**. For the sustainable development of the enterprise, to extend the industrial chain and reduce costs while increasing efficiency, the company decided to carry out further processing on it. Once completed and put into operation, this project will carry out fractional distillation of heavy aromatics and polyhydrocarbons to produce products such as phenol oil, washing oil, anthracene oil, and coal tar pitch. The early operation of this project not only enhances the value of downstream products but also eliminates the classification of these by-products as hazardous waste, achieving a win-win situation in terms of environmental protection and economic benefits. With a total investment of 73.86 million yuan, the project is located in the reserved area to the southwest of the coal-to-natural gas project in the Yili Xintian Coal Chemical Circular Economy Industrial Park, where a processing facility for heavy aromatic and polyhydrocarbon compounds with an annual capacity of 200,000 tons will be built. The project has an annual processing capacity of 200,000 tons, of which 120,000 tons are heavy aromatics and 80,000 tons are polyhydrocarbons per year. This project involves the fractional distillation of heavy aromatics and polyhydrocarbons to produce light hydrocarbons, heavy benzene, crude phenol, washing oil, anthracene oil, and coal tar pitch.
