The mining industry and manufacturing industry in Laos are gradually developing. Small mines, oil refineries and machinery maintenance plants around Vientiane and Xiengkhuang Province produce over 6000 tons of oily sludge each year, mainly from mine mining, tank cleaning and machinery maintenance. The local rainy season is rainy, the oily sludge stacked in the open air is easy to diffuse with the rain, the oil infiltration into the soil pollutes the groundwater, and threatens the ecological environment of Mekong River tributaries; The high temperature in dry season causes the volatilization of oil to generate toxic gas, which violates the strict requirements for water and soil protection in Laos Environmental Protection Law. Laos requires that the oil recovery rate of oily sludge shall not be less than 70%, and the traditional landfill and incineration methods have serious pollution and high energy consumption, which cannot meet the environmental protection requirements. Therefore, the introduction of treatment equipment suitable for local working conditions becomes the key. 

Special research and development of China Yongle Environmental Protection Project for characteristics of oily sludge in Laos: the core adopts the composite process of "low-temperature pyrolysis - chemical demulsification". The pyrolysis temperature is stabilized at about 420 ℃ through the intelligent temperature control system to avoid excessive cracking of oil. The oil recovery rate is stabilized at above 75%. The recovered oil can be directly supplied to the local small factories or mines as fuel; With high sand content, the equipment is equipped with wear-resistant conveying parts and sand oil separation module to extend the service life; In view of the rainy season, the pretreatment stage is equipped with a "precipitation-filtration-dewatering" module to reduce the impact of rainwater on sludge concentration. The main body of the equipment is designed to be waterproof and anti-corrosion to ensure normal operation in the rainy season. 

Application scenarios cover the whole industry chain: in small mines in Xieng Khuang Province, mobile equipment can locally treat oily sludge produced by mining, with a daily treatment capacity of 3-5 tons, avoiding the leakage risk caused by long-distance transportation; the separated oil can be used for the operation of mine machinery, and the residues can be used as paving materials after innocent treatment; In the mechanical maintenance centralized area around Vientiane, the equipment can be connected with the production process of the maintenance plant to realize the "daily production and daily cleaning" of oily sludge, and the modular design can be flexibly adjusted according to the production volume; For the small oil refining workshop in the remote area, the equipment covers only 70 square meters, the operation interface supports dual language in Lao and English, and is equipped with one touch start/stop and fault alarm functions. The staff can operate independently after short-term training. 

We have extensive experience in overseas projects and have provided oily sludge treatment options for a number of mineral resource countries. For the Laos market, assist in completing the compliance filing with the local environmental protection department, and provide the whole process of equipment installation, commissioning and operator training services. Vientiane After-sales Service Center is equipped with spare parts suitable for tropical climate and mine environment. The technical team can arrive at the site for overhaul within 72 hours after equipment failure and provide regular maintenance training. The equipment operation meets the requirements of environmental protection regulations in Laos, helping mines and manufacturing enterprises to realize green production. It is expected to cooperate with mineral enterprises and environmental protection agencies in Laos to solve the problem of oily sludge treatment with high-efficiency equipment and promote the sustainable development of the industry. 

Yongle Environmental Protection is mainly engaged in the research and development, production and sales of complete sets of technical equipment for organic solid waste disposal and comprehensive utilization. Production and manufacturing, domestic waste treatment equipment, tire pyrolysis equipment, medical waste disposal equipment, hazardous waste disposal equipment, and achieve efficient and comprehensive utilization of resources through independently developed low-temperature anaerobic pyrolysis equipment technology solutions.
