How much is the equipment for membrane separation and recovery of organic solvents? Direct answer: There is no unified pricing, and investment fluctuates based on exhaust gas volume, solvent type, and configuration level - process systems with small processing capacity and single components usually start at tens of thousands of yuan, while projects with large air volume and requiring compression condensation film coupling or multi-stage integration can reach millions of yuan. The equipment itself only accounts for a part of the price structure, and preprocessing, automatic control, and installation and debugging also need to be included. The reliable way to quote is to estimate the configuration based on the air volume and concentration of this site, rather than comparing it with a bare machine price. This article clarifies the price composition and estimation criteria.
The first investment decision is to handle air volume: the larger the air volume, the higher the specifications of membrane components, fans, and supporting pipelines, and the price jumps with the specifications. The second item is the type and concentration of solvent: corrosive solvents should be made of corrosion-resistant materials, and high concentrations should be pre concentrated. If there are differences in physical properties, the configuration can be directly adjusted. The third item is integration: simple membrane segments are cheaper, while multi-stage systems such as compression condensation membrane coupling and tower membrane coupling are more expensive but have better unit recovery costs. List the three items clearly so that the supplier's quotation has a comparable basis, otherwise comparing the numbers of different configurations together is meaningless.
The investment of a system is usually divided into five parts: membrane components and separation units, compression and refrigeration pretreatment, automatic control system, pipeline and installation commissioning, transportation and on-site services. Membrane components are the core components, measured by specifications and quantities; Pre treatment involves selecting materials based on the corrosiveness of the medium, which is a major hidden cost; The degree of automation of the control system determines the manpower for operation and maintenance. The details worth discussing in the contract include whether the film is supplied in groups, whether the old parts are recycled at a discounted price, and whether performance retesting is included. These three factors affect the total life cost and will only be used as a low price and low life strategy compared to bare machine prices.
The reliable path for estimation is to collect data first and then negotiate prices: organize the exhaust gas volume, solvent type and concentration range, and operating period, use this set of data to find manufacturers to make configuration plans, and compare at least three companies to see if the configurations are consistent. Only quotations with consistent configurations are comparable, while those with different configurations should be aligned first. The on-site conditions also affect the landing price: whether there are ready-made equipment rooms, whether public works are in place, and explosion-proof level requirements, all of which result in a significant difference in installation costs for the same set of equipment at different sites. Prepare all the data before discussing, the quoted price has much less moisture.
Equipment investment is just a ticket to entry, the real account lies in the recovery income and operating costs: the value of recovered solvents, electricity bills, consumables and maintenance, testing costs, subtracting the four lines to obtain the annual net amount, and then dividing by the investment amount to obtain the payback period. The operation and maintenance of membrane based devices are relatively economical, with a low proportion of electricity costs. The value of recovered solvents often covers the operating costs and has a surplus. Placing the annual average cost and payback period on the table during procurement is closer to the truth than just looking at the initial investment, and it is also easier to make internal decisions.
| price composition | Description | influence |
|---|---|---|
| membrane module | Core components according to specifications and quantity | Amortization based on lifespan |
| Preprocessing | Select materials based on medium corrosion resistance | Hidden Big Head |
| Control system | degree of automation | Determine the manpower for operation and maintenance |
| Pipeline installation | Related to on-site conditions | Significant site differences |
| transportation service | on-site debugging | Easy to miss items |
Most of the differences lie in inconsistent configurations: some with pre-processing, some without, different membrane specifications and materials, and varying degrees of automation; Align the configuration first and then compare prices. Low prices for bare metal devices often rely on reducing items, which requires more money to be paid upon landing.
In terms of scale and integration: small wind volume single membrane systems can reach hundreds of thousands, while large wind volume compression condensation membrane coupling or tower membrane coupling can reach millions; The main difference is the complexity of preprocessing and multi-level integration, not the price increase of the same device.
Looking at the value of solvents and operating costs, membrane based operation and maintenance is cost-effective, with a low proportion of electricity costs. The value of recovered solvents often covers the operation and has surplus; Dividing the annual net amount by the initial investment to calculate the payback period is more reliable than listening to the verbal return period.
