Pembuatan Rancang Bangun Adsorber Penghilang Merkuri Berskala Pilot pada Industri Gas Bumi

Sari

Penelitian pembuatan adsorber merkuri dalam skala pilot telah dilakukan melalui tiga tahap yaitu aktivasi adsorben karbon aktif tempurung kelapa dalam skala besar, pembuatan alat pilot adsorber merkuri berskala pilot dan uji kinerja alat untuk mengetahui kemampuan penyerapan adsorben terhadap merkuri. Aktivasi karbon aktif tempurung kelapa dilakukan pada temperatur tinggi menggunakan activator ZnCl2. Adsorber merkuri berskala pilot dibuat dari bahan stainlessteel yang terdiri dari separator dan dua adsorber. Uji kinerja alat dilakukan dengan mengukur konsentrasi merkuri dalam gas bumi sebelum dan sesudah melewati kolom adsorber. Hasil uji kinerja alat selama sekitar 9 jam menunjukkan adanya penurunan konsentrasi merkuri dengan efisiensi penyerapan adsorben hampir mencapai 100% pada tekanan gas 100 psia, temperatur 37oC dan laju alir gas 50 Cuft/jam.

Research of pilot plan mercury adsorber has been done by three stages, firstly was activation of coconut shell as activated carbon on a large scale, secondly was designed a pilot plan of mercury adsorber and the last stage was performance test to determine the ability of the adsorbent to absorb mercury. Coconut shell activated carbon was activated at high temperature using ZnCl2 as activator. However, the pilot plan mercury adsorber was designed with stainlessteel material consisting separator and two adsorbers. The performance test of was done by measuring the concentration of mercury in gas before and after the adsorption column approximately 9 hours. The test condition as follows; gas pressure 100 psia, temperature of 37C and the gas flow rate 50 CUFT/hour. The test result showed the mercury concentration was decrease significantly with the efficiency of mercury absorption almost 100%.
