The VOCs organic waste gas treatment project involves multiple links and strong professionalism. Many companies simply understand treatment as buying a treatment equipment and installing it, but the results do not meet the standards and the operating costs are high. In fact, a standardized VOCs treatment project requires complete process support from project initiation to acceptance. This article takes the common condensation film treatment project in the oil and gas storage and transportation industry as an example to summarize the key points of the entire process from on-site survey to acceptance and commissioning.
The first step in project initiation is to identify the source of exhaust gas. The key data to be measured includes exhaust gas volume, VOCs concentration, component composition, temperature and humidity, as well as the location and quantity of emission points. These data directly determine the process route and equipment specifications. If the data is inaccurate, the rest will be in vain. It is recommended to test the data of unloading and storage at gas stations, oil depots, and other places, as the concentration differences may be significant under different operating conditions.
After obtaining the working condition data, enter the scheme design phase. The treatment of VOCs in oil and gas usually adopts a combination route of condensation and membrane separation: the condensation module is responsible for recovering most of the oil and gas, and the membrane separation module provides bottom protection to ensure the emission concentration. The processing range of Wohong WHSH series covers specifications starting from 4-20 cubic meters per hour, with a modular structure that integrates compressors, heat exchangers, membrane components, and control systems. When selecting, focus on checking the two parameters of processing capacity and emission concentration, and require the manufacturer to confirm in writing.
The modular equipment is assembled and debugged in the factory, and on-site installation mainly involves basic fabrication, power connection, and gas circuit connection. During the installation phase, several details should be noted: the equipment foundation should be flat and drainage should be considered; The power supply must match the equipment requirements and be properly grounded; The direction of gas path connection should be consistent with the equipment identification to avoid reverse connection. During construction at the gas station, it is necessary to ensure proper fencing and hot work management, and construction personnel must undergo safety training.
Debugging is divided into two stages: no-load and load. No load debugging checks whether the compressor steering, air cooling module operation, and control system display are normal; Load debugging simulates oil unloading conditions to verify whether the automatic start, treatment effect, and emission concentration meet the design values. During acceptance, keep debugging records and operational data as the basis for environmental inspection. After the equipment is put into operation, it is recommended to arrange operator training to master daily inspections and common fault handling.
VOCs treatment is a systematic project, and only with a complete process can equipment play its due value. Every step of selection, construction, and debugging is solid, and only then can the project pass the acceptance inspection in one go. The investment in governance projects is not only limited to the equipment itself, but also includes testing, foundation construction, pipeline renovation, and commissioning costs. When budgeting, it should be considered together to avoid compressing process configuration due to insufficient budget, which may ultimately result in more losses than gains.
