Abstract

Sugar factories in Indonesia are mostly built during the colonial era and therefore are not equipped with suitable environmental management equipment One of the effects of this activity is air pollution in the form of particulate matter from bagasse burning for energy. This study aims to determine the particle distribution of sterile emissions from the Sidoarjo Sugar Factory. The measurement of the sampling point with degradable dust collectors SNI 13-4703-1998 has been revised. The measuring point is scattered around the location of the sugar mill with a certain distance from the center of the chimney. The measurements are carried out for 24 hours at six-hour intervals so that the measurements at each sampling point are four times as long. The results of the particle dust measurements were analyzed by gravimetric method to obtain the particle dust concentration. Computer simulations are presented in the form of contour maps and 3D surface contours from particle dust concentrations. The simulation results show differences in the contour pattern and 3D surface contour due to differences in particle concentration for each measurement period. Each measurement period is also affected by wind speed and direction as well as measuring time by day or night. Keywords: Contour, Dust Faal Collector , Distribution Model, Particulate, Surface

Sidoarjo糖厂烟囱颗粒粉尘分布模型
印尼的糖厂大多建于殖民时代,因此没有配备合适的环境管理设备。这种活动的影响之一是以蔗渣燃烧产生的颗粒物形式造成的空气污染。本研究旨在确定Sidoarjo糖厂无菌排放物的颗粒分布。对SNI 13-4703-1998可降解集尘器采样点的测量方法进行了修订。测量点散布在糖厂周围,距离烟囱中心一定距离。以6小时为间隔进行24小时的测量,因此每个采样点的测量时间是测量时间的四倍。通过重量分析法对颗粒尘测量结果进行分析,以获得颗粒尘浓度。计算机模拟以等高线图和颗粒尘浓度的3D表面等高线的形式呈现。模拟结果显示,由于每个测量周期的颗粒浓度的差异,轮廓图案和3D表面轮廓存在差异。每个测量周期也受到风速和风向以及白天或晚上测量时间的影响。关键词:轮廓线,集尘器,分布模型,颗粒物,表面
