Liron Technology Unique SE-CTMP
-New process of chemical mechanical pulp: broad spectrum of raw materials

To meet fiber raw materials demand, further increase the utilization of agricultural and forestry residues

Non-wood fiber raw materials such as bamboo, reeds, wheat straw, cotton stalks, sugarcane bagasse, corn sorghum straw, etc

Wood fiber raw materials such as: wood processing leftovers, branches, construction waste templates, old house purlins, etc.

Key Advantage of our SE-CTMP offering

Reduce Energy Consumption

SE-CTMP Line: Energy/ton<800kw

Low Investment

SE-CTMP Line: Less than 3 million USD/set

Low operation cost

Energy saving, power consumption/ton pulp only 400-800 kwh

Less staff needed, only 1-2 personnel required during operation

Less chemical usage, only 80kg-100kg/ton pulp consumption

Water and electricity consumption of high-yield pulping method

Traditional CTMP: >1600kwh/ton
Traditional P-RC APMP: >1200kwh/ton
SE-CTMP: <600kwh/ton

Water consumption:
Traditional CTMP : 15ton
Traditional P-RC APMP : 10-12t
SE-CTMP: 4-5t (natural color/Unbleached)
SE-CTMP: 7-9t (bleaching)

Due to increase demand and limited resources, Liron-tech SE-CTMP process offering

  • A wide range of raw materials: various wood chips,
  • What Genda has already experimented: Bamboo (Ci bamboo, water bamboo, red bamboo, moso bamboo, green bamboo, cluster bamboo, etc.), reed, crop straw, camphor wood, frame wood, miscellaneous wood, caragana, and fruit branches. .
  • Investment Saving: equipment investment is only 1/2-1/3 cost compare with other international brand of the same scale
  • Low running costs
  • Easy to use
  • Yield: 70-85% or higher
  • By changing chemicals, chemical dosage, chemical distribution, temperature, pressure, time and energy distribution of refining, se-CTMP meeting different yields can be used to produce unbleached CTMP with a wider range of strengths index.
  • “Semi-chemical mechanical pulp is a kind of pulp without grade, which varies greatly according to the use of the product” (JAMES P. CASEY)
  • Only 25-50% of lignin and 20-40% of hemicellulose are removed, which is 10-40% higher than kraft pulp.
  • By adjusting front-end equipment and/or operations, se-CTMP can be used on a variety of raw materials, including a variety of wood and non-wood materials. The production capacity can be large (500t/d) or small (50~100t/d, acquisition radius), and the yield (70-85% or higher)

Liron Technology Comprehension of chemical mechanical pulp(CTMP) line

Small Scale

Due to raw material distribution limitation and investment scale, 85% of new CTMP production line has annual output of 50,000-100,000 tons.

Smaller Initial investment

During the economic downturn, investors are very cautious and prefer projects with higher cost performance.

Strict energy & environmental consideration

Power consumption,chemicals, heat recovery and waste treatment, becoming key factors which determine the success of the project.

Wide source of materials

Flexibility and adapt to different raw materials with minor process adjustments to achieve smooth production.

No pressure equipment usage

Considering investment cost, safety, operating expenses, etc., production line will be dominated by normal pressure production.

Liron SE-CTMP solution - Normal Pressure High Consistency

Tailor-made for chemical-mechanical pulp production lines with an annual output of 50,000 to 100,000 tons
