 |
The Juhua Corp. Chlor-Alkali/PVC is located in Quzhou, Zhejiang Province.
It is one of many process plants in the Juhua industrial complex. The plant has
800 employees and it manufactures the following products:
| Caustic (NaOH, 35%) | - | 120,000 | metric tonnes per year |
| Chlorine (Cl2) | - | 106,000 | metric tonnes per year |
| Hydrochloric acid (HCl, 28%) | - | 7,200 | metric tonnes per year |
| PVC | - | 35,200 | metric tonnes per year |
The technology of the Chlor-Alkali plant is that of diaphragm cells electrolysis. The technology of PVC manufacturing is the carbide-acetylene based process.
 |
The factory receives assistance in implementing cleaner production from the China-Canada Cooperation Project on Cleaner Production. When implemented, CP solutions would achieve the following environmental objectives:
-
Water Conservation
-
Recovery of finished and intermediary products which are lost to the environment via air emissions and liquid effluents.
At the Juhua Chlor-Alkali/PVC
Plant, CP work has progressed very quickly:
| March 2000 | Process pre-audit and CP training |
| August 2000 | CP Audit, including preparation of process flow sheets, list of environmental emissions and field measurements of air emissions, flow rates and composition of liquid wastes |
| November 2000 | An engineering report based on the CP Audit was issued to present a list of 21 potential CP measures and solutions (CP options) for discussion with the managers and technical staff of the plant. |
|
December 2000 |
Each of the 21 options was reviewed and discussed at the Juhua plant. The discussions addressed order of magnitude capital cost, operating costs, equipment requirements, savings, and environmental benefits. As a result of the review, 9 CP options were selected for implementation. |
| January 2001 | Further engineering work to bring the selected SP options to the implementation, procurement and construction stages - which are planned for the third quarter of 2001. |
