Guangdong Aoheng Environmental Protection Technology Co., Ltd.

MVR evaporator, short for mechanical vapor recompression. MVR is a technology that reuses the energy of its own secondary steam, thereby reducing the need for external energy. The secondary steam is compressed by the compressor, the pressure and temperature can be increased, and the enthalpy increases accordingly. It is sent to the heating chamber left for evaporation as the heating steam, namely the steam, so that the material liquid can maintain the evaporation state, and the heating steam itself will transfer the heat to the material and become condensed into water. In this way, the steam originally to be discarded is fully utilized, the latent heat is recovered, and the thermal efficiency is improved. The price is negotiable

Comate (Hong Kong) Limited

Secondary oil and gas recovery treatment refers to the process of collecting the oil and gas generated when refueling vehicle fuel tanks into underground oil tanks through a sealed method. Due to factors such as complex refueling scenarios, high frequency of manual operations, massive data volume, and vulnerability to external weather and equipment interference, secondary oil and gas recovery has become a link in the oil and gas recovery process of gas stations that features high technical requirements, low recovery efficiency, and poor treatment effects. Its direct manifestation is the generally low qualification rate of the air-liquid ratio of refueling nozzles.The Oil and Gas Recovery Monitoring System developed by COMATE (HONG KONG) LIMITED integrates technologies such as oil and gas circuit flow measurement, air-liquid ratio controller, oil and gas circuit control valve, and central monitoring system. Based on the fueling volume of the refueling nozzle and the oil and gas recovery flow rate, it can control the oil and gas recovery volume in real time to ensure that the air-liquid ratio always meets the standards. Additionally, it centrally displays and stores the real-time and historical data of all fuel dispensers, realizing comprehensive monitoring of the oil and gas recovery system in gas stations, thereby helping to reduce VOCs (Volatile Organic Compounds) emissions.
