Pulp Bleaching in PapermakingApplication
A Third Project Built on Long-Term Partnership
On October 3, 2026, PKU Pioneer successfully completed the test run and start-up of a 3,000 Nm³/h VPSA oxygen generation system for Double A (1991) Public Company Limited (Double A), delivering oxygen at 93% purity. Designed to support the pulp bleaching process, the system provides a reliable on-site oxygen supply for Double A’s pulp and paper production. This represents another significant delivery built on long-standing trust and repeat collaboration between the two parties.
As Thailand’s largest integrated pulp and paper producer, Double A is a leading premium copy paper brand in Asia, with its products distributed to more than 130 countries. The company first engaged PKU Pioneer to revamp its existing oxygen plant, followed by the installation of a new 1,100 Nm³/h oxygen generation unit. For this third project, Double A planned a new 3,000 Nm³/h VPSA oxygen plant based on the oxygen demand of its entire production site. Building on the positive experience with PKU Pioneer’s VPSA systems, Double A once again turned to PKU Pioneer for reliable oxygen supply and stable long-term operation.
Tailored Engineering Solution and Investment Support
Double A attached great importance to this project, completing several years of technical and commercial evaluation before project kick-off. With the client evaluating whether to upgrade its existing oxygen facilities or build a new plant, PKU Pioneer offered a detailed comparison of the initial investment and long-term operating costs of the two solutions, taking into account the site’s total oxygen demand and existing operating conditions. After reviewing the comparison, Double A concluded that building a new plant was the more economical option and accepted PKU Pioneer’s recommendation to invest in a new 3,000 Nm³/h VPSA oxygen plant.
On-Schedule Delivery and Successful Start-Up
PKU Pioneer maintained tight control over the project schedule, ensuring on-time delivery in line with the agreed timeline. Following one week of systematic commissioning, the 3,000 Nm³/h unit successfully completed its test run and was put into production.
Throughout commissioning, PKU Pioneer’s on-site technical team provided responsive support to keep the project on track. PKU Pioneer ensured a timely supply of spare parts and expedited the resolution of technical issues by leveraging close supply chain coordination, contributing to a smooth start-up.
Strengthening a Long-Term Partnership
The successful completion of this application of on-site oxygen generation in pulp bleaching reflects Double A’s continued confidence in PKU Pioneer’s VPSA oxygen generation technology and engineering capabilities.
PKU Pioneer remains committed to delivering tailored oxygen generation solutions backed by professional engineering and responsive technical support, helping pulp and paper manufacturers across Southeast Asia ensure reliable oxygen supply and efficient plant operation.
