Complete Formaldehyde Plant EPC Solutions
As an experienced formaldehyde plant EPC contractor, we deliver fully integrated turnkey solutions covering the entire lifecycle of industrial formaldehyde production facilities.
Our scope includes:
Process design and engineering
Equipment manufacturing and sourcing
On-site installation and construction
Commissioning and plant startup
Operator training and technical support
With over 10 years experience, SL Tec focus on formaldehyde production technology based on silver contact process(or silver catalyzed process). A lower methanol consumption, higher formalin product concentration, high export steam capacity and ease of operation are our features, which makes it the best technical and economically viable solution. Every unit operation including methanol evaporation, catalytic reaction, absorption, off-gas treatment has optional design to at best satisfy the customer's needs.
One-stop Package Solutions Formaldehyde Plant
We provide one-stop package solutions from the formaldehyde plant design, manufacture, erection, commissioning, startup to training, with the production capacity of 6,000TPA – 120,000TPA and the formaldehyde product concentration varying from 37-55%. And according to the customer's different needs, there are totally 7 (seven) optional processes as follows:
1) Traditional Bubble Evaporator + Absorber with 3 (three) Concentration Gradients to produce 37% formalin
2) New Evaporator + Absorber with 3 (three) Concentration Gradients to produce 37% formalin
3) Off-gas Circulation + Re-boiler + Absorber with 3 (three) Concentration Gradients to produce 37-42% formalin
4) Off-gas Circulation + Re-boiler + Absorber with 3 (three) Concentration Gradients to produce 37-55% formalin
5) Off-gas Circulation + Evaporation Column + Absorber with 6 (six) Concentration Gradients to produce 37-55% formalin
6) Off-gas Circulation + Multipurpose Evaporator + Absorber with 6 (six) Concentration Gradients to produce 37-55% formalin
SL Tec is professional supplier of formaldehyde production and formaldehyde plant turnkey solutions according to different requirement from customers. We focus on Formaldehyde plant for sale at low cost. Please contact us to let us know your situation, and we would like to offer the perfect formaldehyde plant design for you.

Typical Product Specifications
| Item | Index |
|---|---|
| Formaldehyde | 37–49% WT |
| Methanol | ≤1% WT |

Advanced Process Technology Options
We primarily adopt the silver catalyzed process, recognized for its economic efficiency and operational stability.
To match different investment levels and product targets, we offer multiple process configurations:
Traditional evaporator + absorber systems for standard 37% formalin
Advanced off-gas circulation systems for higher efficiency
Re-boiler and multi-stage absorption designs for higher concentration output
Multipurpose evaporator systems for flexible production (37%–55%)
Each configuration is engineered to balance:
Capital investment
Operating cost
Energy efficiency
Product quality
Key Advantages for Industrial Buyers
Instead of just technical features, our solutions focus on measurable business outcomes:
Lower Operating Cost
Optimized methanol consumption (as low as 0.445 mt/mt)
Energy-efficient heat recovery and steam utilization
Higher Production Efficiency
High conversion yield
Stable continuous operation
Energy Recovery & Utilization
Significant steam export from off-gas boiler and WHB
Reduced overall plant energy cost
Reliable and Long-Term Operation
Durable reactor design
Low maintenance requirements
Extended catalyst service life
Consistent Product Quality
Low formic acid content
Controlled pH and impurity levels
Utility Consumption Reference
| Item | Consumption |
|---|---|
| Methanol | 0.445 mt/mt (37% formalin) |
| Power | 28 KWH/mt |
| Steam Production | 400 kg + 180 kg per mt |
