Over the past few years, at apurio Umwelttechnik, we have had the opportunity to solve a wide range of projects and challenges related to air purification for our customers. Below, you will find a selection of representative reference projects, along with a description of each project’s initial situation, objectives, and how we implemented the solution. We hope you enjoy browsing through them.
MQL Separator for Aluminum Processing
MQL Separators (Minimum Quantity Lubrication separators) are used in aluminum processing to reduce the amount of lubricant required during the machining process. This results in lower environmental impact, improved workplace safety, and cost savings due to reduced lubricant consumption and simpler chip disposal.
Initial Situation
For the conversion of various production processes of a well-known automotive manufacturer regarding electromobility, everal process exhaust air systems were newly installed, and existing systems were modified.
One of the newly installed exhaust air purification systems was an MQL separator from apurio Umwelttechnik for aluminum and MWF-containing process exhaust air from 8 machining centers (MQL: Minimum Quantity Lubrication, BAZ: Machining Center).
The scope of delivery included a turnkey complete system,
consisting of the MQL separator MMSF-10-1.2 including MSR (Measurement/Control/Regulation technology), the fan with silencer, the control cabinet, the suction-side piping up to the interfaces on the machining centers, the pressure-side piping through the roof including deflector hood, and the dust discharge system.
The dust discharge system consisted of a rotary valve, pipe screw conveyor, drop tube, and cart with control panel. The MQL separator is equipped with a fire alarm system and fire water piping for safety.
Objective
The objective was the reliable implementation of all new installations and modifications before the start of production.
Implementation
After commissioning and clarifying the technical details, flow diagrams and component lists were created, and the necessary in-house plant components were designed and manufactured (including MQL separators, pipeline elements).
External plant components (including fans with silencers, MSR, electrical components) were commissioned and coordinated.
Due to long delivery times caused by the pandemic and war-related issues, quick and cost-effective temporary solutions were implemented to avoid jeopardizing the schedule. Short-term change requests and revisions were promptly and smoothly accommodated.
After the delivery of the plant components, the installations were set up. To prevent and mitigate delays, various on-site construction services were spontaneously undertaken and executed by us. Upon completion, all safety checks were conducted, the systems were calibrated, technical documentation was handed over, and the client’s employees were trained.
Outcome
The systems were handed over ready for operation despite high order volume, various changes and rescheduling, as well as delivery bottlenecks at the start of production.In doing so, we were able to distinguish ourselves with our responsiveness and high flexibility, leading to further major projects being realized subsequently.
Packed Scrubber for Wastewater Pretreatment
Initial Situation
Due to an insufficient existing exhaust air purification system for extracting tanks in a wastewater pretreatment plant, there were regular exceedances of sulfur dioxide and nitrogen oxide limit values in the premises of a well-known automotive manufacturer, leading to fire brigade alarms.
Accordingly, a new exhaust air purification system was to be implemented to permanently comply with the limit values.
The scope of delivery included a turnkey complete system,
consisting of a base scrubber (type: packed bed scrubber, material: PP (polypropylene), washing agent: NaOH (sodium hydroxide)) including MSR, nozzles with washing agent supply and drip tray, the raw gas-side fan, the control cabinet, the suction-side piping up to the interfaces, the pressure-side piping over the roof, as well as the fresh water supply up to the interface and the wastewater discharge to the interface.
Objective
The goal was to promptly install a more powerful exhaust air purification system that operates continuously and ensures the permanent compliance with the sulfur dioxide and nitrogen oxide limit values in the respective premises.
Implementation
Upon commissioning and clarification of technical details, flow diagrams and parts lists were created. In collaboration with our partner company specializing in plastic processing, components made of PP (polypropylene), including the scrubber tower and piping elements, were designed and manufactured.
External components (such as the fan with silencer, sensors, and electrical components) were procured and coordinated.
Upon delivery of the components, the system was installed. Following completion, all safety checks were conducted, the systems were calibrated, technical documentation was provided, and the client’s personnel were trained.
Since the project’s completion, the operator of the system has been supported in maintaining the exhaust air purification system (e.g., monthly calibration of pH sensors, annual maintenance and inspection including cleaning, sensor testing, and airflow measurement).
Outcome
Since its completion, the new system has consistently maintained compliance with the exhaust air limit values. The system was operational in less than three months after commissioning. Our expertise, built on decades of industry knowledge, contributed to this achievement. As the sole bidder out of a dozen, we were able to execute this project under the prevailing conditions.
