Yatong Petrochemical plans to build a 1.2 million tons per year naphtha comprehensive utilization project

Thread Content

On December 24, 2018, the \"Public Disclosure of the First Environmental Impact Assessment Information for Dongying Yatong Petrochemical Co., Ltd.’s 1.2 million tons per year naphtha comprehensive utilization project\" was released. The project is located in the Dongying Port High-End Petrochemical and New Materials Industrial Park, and it is an expansion project. Existing projects and their environmental protection measures: an 1.8 million tons per year high-grade heavy traffic asphalt production facility, an 800,000 tons per year catalytic cracking plant, a 200,000 tons per year gas separation unit along with a 40,000 tons per year MTBE production facility, a 250,000 tons per year aromatics plant, a 160,000 tons per year liquefied gas deep processing facility, an 800,000 tons per year catalytic cracking (DCC) facility for hydrogen production via the recovery of flared gases, as well as Phase 1 of the “dry gas recovery for hydrogen production, sulfur recovery, and hydroprocessing projects” (including a 300,000 tons per year electrode material production unit, a 1 million tons per year chemical oil hydroprocessing unit, and a 15,000 tons per year sulfur recovery unit). There are also various environmental and safety facilities such as accident containment tanks and flares. Based on the environmental impact assessments, acceptance inspections and related approvals, as well as routine monitoring data for existing projects, the pollutants emitted by these projects all meet the specified standards. Project construction content: The 1.2 million tons/year naphtha comprehensive utilization project consists of the main naphtha comprehensive utilization unit and a 20,000 Nm3/h PSA unit. The main unit consists of a raw material pretreatment section, a reaction heating furnace, a reaction section, a regeneration section, an absorption stabilization and pentane removal section, a propane removal section, a heavy fraction removal section, as well as triphenyl extraction units ； The utility and auxiliary production facilities rely on the existing facilities within the plant. A 13MW gas-fired heat transfer oil furnace is planned to be installed in the existing 25 tons/year aromatic compound plant, using excess flare gas to reduce pollution. Add low-nitrogen burners to the heating furnaces of existing projects. The 1 million tons per year chemical light oil upgrading project is undergoing technical upgrades to add an extraction process; meanwhile, the naphtha aromatization project planned to be constructed will utilize this extraction process for triphenyl extraction. A main substation will be built at the South Plant.
