PROJECT OVERVIEW
North China Petroleum Bureau Co., Ltd. and North China Oil and Gas Branch is a professional team of oil and gas exploration and development with a glorious history of 60 years, covering 22 provinces (municipalities and autonomous regions) in China, and playing a strategic leading role and making important contributions to the discovery and construction of oil and gas fields such as Daqing, Shengli, Central China Plains and Jianghan, etc. After merging into SINOPEC in 2000, it has successfully developed Da Niu Di gas field, the first large-scale gas field constructed by SINOPEC itself, and become the main gas source of SINOPEC in North China. After merging into SINOPEC in 2000, SINOPEC successfully developed the Da Niu Di gas field, the first large gas field built by the Group, which became the main source of gas for SINOPEC in the North China region, and effectively supported the economic construction and regional development of the provinces and regions along the Yellow River Basin, and realised a successful transition from a traditional geological exploration unit to an oil and gas field enterprise. "At the end of 2012, after professional restructuring, the company realised the operation of oil bureau, oil company and engineering section in three parts, and changed its name to North China Petroleum Bureau Co.
PROJECT INTRODUCTION
Exhaust sources
water treatment plant
Exhaust air volume
42,000m³/h
Exhaust gas composition
H2S, NH3, dimethyl disulphide, amines, mercaptans, styrene, acetaldehyde, propionaldehyde, butyraldehyde, etc.
Project location
Yulin City, Shaanxi Province
ECLEAR SOLUTION
Design air volume
42,000m³/h
Design process
YQWT spray washing + YQHX activated carbon adsorption process
Pre-wash systems
The exhaust gases are collected and piped into the pre-treatment stage, where the alkaline/acidic gases in the exhaust gases are neutralised and scrubbed using acid/alkali solution.
adsorption system
The pre-treated exhaust gas enters the adsorption system through the filler, and when passing through the carbon layer, the organic pollutant molecules enter into the micropores and are adsorbed by the active sites on the surface of the carbon layer through physical adsorption and chemical adsorption.
Exhaust gas emission system
Exhaust emission standards and discharge heights can be achieved by selecting a combination of explosion-proof fans and high altitude discharge pipework as required.
COMPLIANCE REQUIREMENT
| Odor components | Odor inlet indicators | Odor discharge indicators | Exhaust pipe height |
| H2S | ≤100mg/m3 | ≤0.6kg/h | 15m |
| NH3 | ≤40mg/m3 | ≤0.6kg/h | |
| C2H6S | ≤50mg/m3 | ≤0.6kg/h | |
| Odour | ≤3000 | ≤800 |

Eclear Environmental RELATED EQUIPMENT
Spray tower
Spray tower, as a type of environmental waste gas treatment equipment, exists. According to its working principle, it can be divided into circulating water spray tower, alkali spray tower, and acid spray tower (also known as acid washing tower). According to the material of the tower, it is divided into fiberglass spray towers, PP spray towers, and stainless steel spray towers. Choose a reasonable spray material and spray process based on the different properties of the exhaust gas. Spray tower is an important industrial waste gas treatment equipment, whose working principle is to use water and power technology to spray liquid or gas in a mist form into the waste gas, in order to remove harmful substances in the waste gas.
Activated carbon adsorption box
Activated carbon adsorption box is an environmentally friendly mechanical product that filters waste gas and adsorbs odors. This equipment is used to clean organic chemical waste gas and spray waste gas with high concentration. Activated carbon has a high-strength adsorption level. When the waste gas is powered by a centrifugal fan, negative pressure enters the adsorption box and then enters the activated carbon adsorption layer, it has a very good adsorption effect on organic solution waste gas.
Adsorbent
The core of Eclear waste gas treatment system is Eclear dry gas phase filtration material. The Eclear dry gas phase filtration material is made using a proprietary special process and is spherical and porous in particle shape. The adsorption filter material removes odorous gases through chemical adsorption. When the collected odorous gases pass through the filter material, a chemical reaction occurs instantly when the filter material comes into contact with the odorous gas, thereby quickly and effectively removing the odorous gas. In the process of removing odorous gases, they are converted into harmless salts, which are irreversible. Once pollutants are removed from the environment, they cannot return to the air, effectively preventing secondary pollution of the air environment and ensuring safety and environmental protection.
Washing tower
Washing tower is a mature waste gas treatment equipment widely used in pre-treatment of industrial waste gas treatment, dust removal, and other aspects. Gas enters the tower and fully contacts, adsorbs, and dissolves with the washing liquid inside the tower, achieving purification effect. The design forms of Yi cleaning towers are diverse, and vertical or horizontal structures can be used according to the project application site. The commonly used materials for washing tower equipment include PP, FRP, and stainless steel. PP and FRP are commonly used in chemical absorption towers and have the characteristics of acid resistance, alkali resistance, and corrosion resistance. Stainless steel materials can be used for high-temperature exhaust gas.
VOCs integrated processing equipment
The activated carbon adsorption box (YQA all-in-one machine) is a VOCs waste gas treatment equipment developed by Eclear Environmental through years of research and engineering experience combined with the photocatalyst technology of university research institutions. It adopts a dual process combination of photocatalytic oxidation and activated carbon adsorption, as well as an integrated design concept.
