Wet Scrubber Performance Optimization Application Assisted With Electrochemical-Based Ammonia Sensors

Abstract

Crumb rubber is one of Indonesia’s agroindustry export commodities. This industry faces environmental problems due to their wastes, both liquid and air. The source of air pollution is commonly from drying process that emitted odor from its evaporation and heating phenomena. Industry uses wet scrubber technology as air pollution control from emitted odor from drying process. Preliminary identification in noncontrolled wet scrubber shown that wet scrubber efficiency around 47%. Low efficiency wet scrubbing process causes rain drop of water vapor around drying process. This research used electrochemical based sensor MICS 5524 as ammonia monitoring instrument, assisted with arduino as microcontroller to regulate water discharge through valve controlling scrubbing process. This electrochemical based sensor reads ammonia based on voltage reads by Arduino microcontroller. Ammonia reading then control scrubbing process by adjusting valve opening for spray water distribution. Wet scrubber efficiency increases to 66,96% due to water scrubbing control, also can save water utilization as high as 61,90%, followed by absence of rain drop contains ammonia around drying process area.

Photocatalytic Degradation of Toluene and BTEX Compounds in Gas Reactor Modified by TiO2/Ti Net Nanotubes

“…The photocatalytic performance of the TiO 2 /Ti Net Nanotube was evaluated by assessing the degradation of toluene steam and BTEX gas standard in the homemade gas reactor. The intermediate compound or bypass product formation, such as CO 2 , was detected and analyzed using an electrochemical sensor (Sari et al, 2019). The results of this study are bene cial in providing new options for material choices for photocatalytic degradation that can be applied in industry, speci cally industries dealing with VOCs such as toluene and BTEX.…”

Relationship between Economy and Environment of the Natural Rubber Plantation in Major Producers

“…As a commercial commodity, rubber is not only meet the domestic demand but also look for the overseas rubber demand. It has an important role in gaining income through the foreign exchange of the major rubber producing countries [5]. Therefore, in the past few years, policy has been changed to promote the industrial export activity and successfully introduced natural rubber as one of the largest agricultural export commodities besides oil palm, coffee, and cocoa [6].…”
