The Nghi Son Refinery and Petrochemical Complex is a flagship national project, leveraging world-class, cutting-edge technologies with a total investment exceeding USD 9 billion. Developed by Nghi Son Refinery and Petrochemical LLC (NSRP), the project is backed by leading oil and gas corporations from Japan, Kuwait, and Vietnam. Designed for a 70-year operational lifespan, the complex plays a pivotal role in safeguarding Vietnam’s energy security while contributing significantly to the country’s economic development.
Groundbreaking commenced on October 23, 2013. Following the completion of construction and full synchronization of technological units, the refinery entered commercial operation. Today, the facility operates at high capacity with stability and efficiency, ensuring a safe and seamless production and business chain that meets domestic demand and supports export markets.
In strict compliance with environmental protection regulations and through safe, stable operations, NSRP has been officially granted Environmental Permit No. 488/GPMT-BNNMT by the Ministry of Agriculture and Environment. This milestone underscores NSRP’s unwavering commitment to legal compliance, environmental risk management, and adherence to the highest operational standards.
The issuance of this permit affirms regulatory recognition that the refinery meets all requirements for environmental management, monitoring, and control throughout production processes. It further reinforces NSRP’s pledge to maintain sustainable, efficient operations—contributing to national energy security and driving Vietnam’s socio-economic growth.
To minimize air pollution during its operation, NSRP has applied various advanced pollution abatement technologies to satisfy the air emission standards such as: designing proper height of stacks, using Low-NOx burners for heaters, De-NOx by SCR, De-dust by ESP and De-SOx by seawater for boiler emission; De-NOx by SCR, De-SOx and De-dust at CO incinerator of RFCC Unit, tail gas treatment system at SRU to recover maximum liquid Sulphur, VRU at truck loading and Jetty.
SOx, NOx, Dust emissions emitted to environment are monitored by online emission monitoring systems installed on 20 stacks following requirements at EIA approving Decision. Furthermore, NSRP has also installed 03 Ambient Air Quality Monitoring Systems (AAQMS) at different locations inside the Refinery.
The Effluent Treatment Plant (ETP) of NSRP was designed with 2 parallel treatment chains with the capacity of each chain being 350m3/hour. The sources of effluent coming from process and domestic units are collected and treated in the following processes: API Oil separator—API secondary oil separator, FFU and DAF, Bio treatment package, tertiary oxidation package (ozone), tertiary physiochemical treatment package (absorbed by activated carbon). The entire ETP is operated automatically and semi-automatically through another automatic measuring system. Besides, the ETP is also equipped with a spent caustic treatment package and catalyst oxidation system to treat vent gases from the other packages. Treated wastewater is monitored by an online monitoring system for flow rate, temperature, pH, COD, TSS, Total Nitrogen, total P, Phenol and total oil and grease which has been installed at treated transfer sump.
Wastewater from Demineralized Unit, from FGD and cooling seawater are properly treated and monitored by online monitoring systems for typical parameters prior to discharging into the environment complying with applicable regulations.
Additionally, NSRP engages with an authorized monitoring center to monitor the quality of treated wastewater periodically. The monitoring results indicate that all the pollution contents are below the allowable limits of QCVN 40: 2011/ BTNMT.
Follow the requirements at Circular 36/2015/TT-BTNMT – Hazardous waste management, NSRP has registered the Hazardous Book Owner No. 38000296.T to Thanh Hoa Department of Natural Resources & Environment. NSRP installed 18 temporary HW storages at various locations within the process area and 1 centralized HW storage with an area of 700m2 to store the wastes prior transferring to contractor. NSRP also signed a Contract with Nghi Son Environment Joint Stock Company to collect, transport and treat hazardous and non-hazardous wastes generated during its operation.
NSRP also built a fluidized bed incinerator which applies advanced Japan’s technology which is applied in Vietnam for the first time to treat sludge waste generated from ETP and waste oil from PPU. Flue gas treatment system of the incinerator including quencher to control the formulation of Dioxide, bag filter to remove dust and acid absorber by caustic. Flue gas quality is monitored by online analyzers for total dust, SOx and NOx to assure the concentrations of pollutant satisfy QCVN 30:2012/BTNMT prior discharging into the environment.
To minimize noise, units and equipment generating high levels of noise such as Boilers, Turbine Generators etc., are located at the center of the Refinery and silencers are used to lower the noise. Additionally, operators who work in workplace environment with high noise levels (>85 dB(A)) are equipped with proper PPEs.
NSRP has successfully developed and applied the Integrated Management System (IMS) following ISO 14001:2015 for environmental management system and ISO 9001:2015 for quality management system which have been assessed and certified as complying with ISO 14001 and ISO 9000 by DNV-GL on 22/3/2019.
The Company also obtained Certificates and Licenses of environmental, health & safety and firefighting and fire protection following Vietnamese regulations such as Permit for discharging wastewater into water source, Permit for seawater exploitation and using, registration of hazardous waste owner book, approval of Oil spill contingency plan, approval of chemical incident prevention and response plan, and certificate for appraising and approving firefighting and fire protection plan.
Following the right direction, NSRP is thriving to become one of the most admired refineries in Asia, not only in terms of product quality, economic efficiency, but also in safety and environmental protection.
