A few days ago, the oil and gas efficient combustion device (VCU) introduced and promoted by Nanjing Du Le Refrigeration Equipment Co., LTD., a wholly-owned subsidiary of Willy Environmental Protection Group, finally landed in Dongying, Shandong Province, which is the great beauty of Canghai in the east, Taihang in the west, Jianghuai in Nantong, and Jingjin in the north.

Project background

Oil and gas efficient combustion device (VCU) is mainly used in petrochemical industry oil and gas treatment, is a kind of incineration oil and gas treatment device. Compared with other existing oil and gas treatment equipment, VCU equipment has a wide range of adaptability and reliable safety advantages, which is favored by the industry and users. 

Because the process device in Europe, the United States, Japan and South Korea and other countries have more application cases, in the domestic application case is less, so the user is hesitant in the choice. Since the introduction of the VCU device, all the Dole people have worked together, closely united day and night, and finally under the personal leadership of the chairman, the Dole team has gone through more than half a year of communication and technical demonstration. Guannao Kelida Petrochemical Co., LTD. (hereinafter referred to as "Kelida Petrochemical Company") finally chose to adopt the VCU device introduced and promoted by Nanjing Du Le - VCU15000 type oil and gas efficient combustion device (oil and gas processing scale of 15000 square/hour). 

Solution

It is understood that Kelida Petrochemical Company VOCs treatment project involves tank farm, unloading area, loading area and sewage treatment tank farm as well as the new plant storage and transportation facilities and other units. In this project, all atmospheric internal floating roof tanks and fixed roof tanks are closed to collect the exhaled air. The exhaled air of all unloading zero tank pools is sealed and collected; The asphalt loading is changed to closed loading, and its volatile gas is closed collection. At the same time, the existing VOCs management device is upgraded. This project collects and pretreats gases from different sources and compositions respectively, which belongs to the VOCs comprehensive treatment project of the whole plant. The oil and gas components are complex, the physical properties are different, the treatment process is complex, and the technical difficulties are many and difficult. 

The VCU process unit is suitable for a wide range of oil and gas concentrations, and has high safety. It is suitable for the treatment of complex waste gas components and high concentration waste gas, and is the best choice for the comprehensive treatment of VOCs in this project. 

Introduction to VCU devices

VCU equipment is an environmental treatment equipment that introduces the generated VOC gas into the combustion chimney at 800~1000 ° C and then decomposes it into harmless, odorless clean gas to be discharged into the atmosphere. 

VCU process flow chart

VCU features and advantages

• The processing efficiency reaches 99.99%;

• Can handle a variety of gases;

• No need to preheat, can be directly burned, the equipment starts quickly (within 1 minute);

• High concentration gas can be directly entered without dilution;

• Simple structure design, low maintenance cost

• Safe and reliable anti-tempering design.

VCU is a highly anticipated high-end process technology in the industry in recent years, and has unique advantages in the field of high-standard exhaust emissions, which is expected to be more and more widely used in the petrochemical industry and even the oil and gas treatment industry.

Project significance

The successful landing of the VCU device not only solved the problem of VOCs exhaust gas treatment for users, helped Kelida Petrochemical Company green production, but also filled the gap in the field of high concentration oil and gas incineration treatment of Nanjing Du Le, and accumulated the promotion experience of Nanjing Du Le and VCU device application cases. 

Experts say

VOCs is the abbreviation of Volatile Organic Compounds.

In atmospheric environmental governance, VOCs refers to organic compounds that participate in atmospheric photochemical reactions, including non-methane hydrocarbons, oxygen-containing organic matter, chlorine-containing organic matter, nitrogen-containing organic matter, sulfur-containing organic matter, etc., which are important precursors for the formation of ozone and fine particulate matter (PM2.5) pollution. Therefore, to win the blue sky defense war, the pollution prevention and control of VOCs has become one of the key measures. 

Nanjing Du Le, a wholly-owned subsidiary of Wiley Group, is a high-tech enterprise specializing in VOCs standard emission and recycling. With the mission of energy conservation, emission reduction and environmental optimization, Nanjing Du Le targets chemical enterprises such as Sinopec, petrochina, CNOOC, Yanchang Petroleum and private petrochemical, involving the fields of emission VOCs such as terminals, storage, transportation and marketing of refined oil products, packaging printing and spraying. The "all delight" series of condensing, adsorption, absorption, membrane separation and catalytic oxidation technologies have been developed successively to form a variety of combined processes based on condensation and adsorption. The performance of the skid-mounted oil and gas recovery unit produced is stable, ensuring the comprehensive treatment and recovery of VOCs and achieving emission standards.
