At Gasunie metering and regulating stations around the country, low caloric natural gas is reduced from up to 66.2 bar to 40 bar or lower for further transport to Gas receiving stations. Various emitting (pneumatic) components are used for pressure control. The metering and control stations date from the 1960’s and 1970’s, with one of the crucial components (also dating from that time period) being a so-called continuous gas-emitting HPSD Control Cabinet (hereafter: HCC). Currently, within Gasunie, the HCC is controlled by a Bristol 624II pneumatic PI controller. which is a controller operating on the vane nozzle principle. A vane nozzle controller always seeks a balance between the vane and the nozzle and emits continuously, when in control. Because of our corporate social responsibility we want to reduce gas emissions as much to zero. Another main project driver, driven by the Gasunie CSR policy, concerns stopping, or if zero emitting products are commercially not available, stron The scope consists of the supply of so-called HCC’s. to replace the current continuous emitting HCC’s. Within the Gasunie 'I.014513-MVO Emission Free M&Rs' project, an estimated number of 104 HCC’s will be replaced with new HCC’s. Awarded supplier shall design, manufacture, deliver and put into operation the complete HCC in accordance
