The WLDBVR-AD series of adsorption vapor recovery equipment developed by Viland is composed of two alternate adsorption and desorption adsorption tanks, and adopts a pressure swing adsorption process.

The main configuration of the device: adsorption tank, vacuum pump, heat exchanger, oil and gas separation tank, liquid return pump, electrical and control system, etc.

Technical features: It can well control the exhaust gas emission concentration.

Application areas: adsorption and separation of low-concentration organic matter.

The condensing temperature of the WLDBVR-CD series condensing method oil and gas recovery device is realized in the steps of pre-cooling, first-stage refrigeration, and second-stage refrigeration according to different oil and gas components and recovery requirements.

The main configuration of the device: pre-cooler, condenser, mechanical refrigeration device, oil and gas separator, etc.

Technical features: less affected by external temperature and pressure, stable recovery effect; good safety; short process flow, simple process, easy to operate and maintain; large operating flexibility; small footprint; no secondary pollution, recyclables can be recycled Directly sell or use.

Application range: Almost all single materials of VOCs gas, and mixture materials that do not react with each other at low temperature.

The absorbent used in the WLDBVR-AB series absorption method oil and gas recovery device is based on the actual situation of the project implementation site, and the materials are taken on-site to minimize absorbent consumption and regeneration costs.

The main equipment includes absorption tower, desorption tower, lean oil/rich oil/absorbent transfer pump, lean oil/rich oil/absorbent storage tank, desorption equipment (such as vacuum pump), etc.

Technical features: The process flow is simple and easy to realize; the absorbent can be selected on site according to the actual situation of the project (such as lean oil), and the recovered oil and gas can be directly sent to the device for use (such as rich oil); the device occupies a small area and is operated convenient.

Scope of application: oil depots, refineries and other places where it is convenient to obtain materials for lean oil and where emission indicators are not high.

The membrane separation organic vapor recovery system is mainly composed of a membrane separation system and an organic vapor recovery system.

The devices mainly include membrane modules, pump units (compressor units, vacuum pump units), filters, valves, instruments and pipelines, etc.

Technical features: low energy consumption; the membrane separation process is carried out at room temperature; azeotrope and components with similar boiling points can be separated; the pressure difference is the driving force, the device is simple, and the operation is convenient.

Application range: In the actual use process, only the integration and coupling of membrane separation process and condensation, adsorption, absorption and other processes can form a more effective technical and economical.
