Anhydrous formaldehyde plant
SL TEC has close to ten years experience in 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 incl. methanol evaporation, catalytic reaction, absorption, off-gas treatment has optional design to at best satisfy the customer’s needs.
We provide one-stop package solutions from the , 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
