NP Rolpin called upon Cap Ingelec to replace their old biomass boiler room with a more economically efficient solution that would meet the new regulatory requirements in every respect. After having carried out a feasibility study, the engineering company submitted a PMG Engineering & Construction offer for a liquefied natural gas (LNG) boiler room which was validated, the investment cost having been judged to be particularly optimized.
Part of the Japanese Nankai Plywood Group since 2014, NP Rolpin is located in the heart of the Landes de Gascogne forest, in Labouheyre.
The company elaborates on its site building materials in maritime pine from 100% Landes forest. It manufactures 3 million m² of plywood per year according to a production process which requires significant steam needs. In this context, NP Rolpin chose Cap Ingelec’s solution to create a liquefied natural gas boiler room. It is the most important LNG boiler room in France to date. It is articulated around two boilers with a unitary production of 14 tons/hour for a delivery of saturated steam at more than 21 bars. Supplied with liquid gas by a large carrier, a storage tank of 120 m3 ensures an autonomy of 2 days of activity at full power.
These infrastructures, boilers and gas storage area, cover a total surface of about 500 m². Architectural care has been taken to integrate these spaces into the environment. Similarly, special acoustic treatment was developed to comply with regulations. The work, which lasted about a year, was carried out on an occupied site. This project was delivered last February, with a procedure elaborated by Cap Ingelec to change from the old, obsolete steam production system to the new, more efficient, economical system which meets European standards.
