module sealing is essential. Gaps between blocks or between the blocks and the equipment housing can allow untreated gas to bypass the adsorbent.

When the inlet temperature rises, adsorption capacity may decrease, and previously captured compounds may desorb more easily. The heat released during adsorption can also raise the temperature inside the carbon bed, especially when VOCs concentrations fluctuate or become unexpectedly high.<\/p>\n<p>Moisture may compete with some VOCs for pore volume and adsorption sites. The severity of this effect depends on the surface properties of the carbon, the VOCs species, concentration, temperature, and relative humidity. For this reason, one universal humidity limit should not be applied to every activated carbon and every VOCs mixture.<\/p>\n<p>The US Environmental Protection Agency identifies outlet VOCs concentration, regeneration conditions, carbon activity, bed temperature, inlet temperature, airflow, inlet concentration, pressure differential, moisture content, and leakage as relevant indicators of carbon adsorber performance. <a href=\"https:\/\/www.epa.gov\/air-emissions-monitoring-knowledge-base\/monitoring-control-technique-activated-carbon-adsorber\" target=\"_blank\" rel=\"noopener\">US EPA \u6d3b\u6027\u70ad\u5438\u9644\u5668\u6280\u672f\u6307\u5357<\/a><\/p>\n<p>\u7c89\u5c18\u3001\u6f06\u96fe\u3001\u6cb9\u6ef4\u4e0e\u51b7\u51dd\u6db2\u4f1a\u5835\u585e\u6d3b\u6027\u70ad\u7684\u5916\u8868\u9762\u6216\u5185\u90e8\u5b54\u9699\uff0c\u8fd8\u4f1a\u589e\u5927\u7cfb\u7edf\u538b\u964d\u5e76\u9020\u6210\u6c14\u6d41\u5206\u5e03\u4e0d\u5747\u3002<\/p>\n<p>\u8702\u7a9d\u70ad\u5bf9\u5b54\u9053\u5835\u585e\u5c24\u4e3a\u654f\u611f\uff0c\u800c\u9897\u7c92\u5e8a\u5c42\u53ef\u80fd\u51fa\u73b0\u8868\u9762\u5835\u585e\u6216\u5c40\u90e8\u6d41\u8def\u3002\u56e0\u6b64\u5de5\u4e1a\u6d82\u88c5\u7cfb\u7edf\u5e94\u5728\u5438\u9644\u6bb5\u4e4b\u524d\u8bbe\u7f6e\u5408\u9002\u7684\u9884\u5904\u7406\uff0c\u5982\u5e72\u5f0f\u8fc7\u6ee4\u3001\u9664\u96fe\u6216\u51b7\u51dd\u63a7\u5236\u3002<\/p>\n<h2>\u9009\u62e9\u6d3b\u6027\u70ad\u524d\u5e94\u6838\u67e5\u54ea\u4e9b\u53c2\u6570\uff1f<\/h2>\n<p>A reliable VOCs control design should evaluate at least the following information:<\/p>\n<ul>\n<li>\u5b9e\u9645\u98ce\u91cf\u53ca\u9884\u671f\u6ce2\u52a8\u8303\u56f4\uff1b<\/li>\n<li>Inlet VOCs concentration and required outlet concentration;<\/li>\n<li>VOCs mass flow rate;<\/li>\n<li>Individual VOCs species and their proportions;<\/li>\n<li>\u5e9f\u6c14\u6e29\u5ea6\u4e0e\u76f8\u5bf9\u6e7f\u5ea6\uff1b<\/li>\n<li>\u7c89\u5c18\u3001\u6cb9\u96fe\u3001\u6f06\u96fe\u4e0e\u6db2\u6ef4\u542b\u91cf\uff1b<\/li>\n<li>\u76f8\u5173\u6d4b\u8bd5\u6761\u4ef6\u4e0b\u7684\u52a8\u6001\u5438\u9644\u5bb9\u91cf\uff1b<\/li>\n<li>\u98ce\u673a\u53ef\u7528\u538b\u529b\u4e0e\u53ef\u63a5\u53d7\u7684\u7cfb\u7edf\u538b\u964d\uff1b<\/li>\n<li>\u6c14\u901f\u4e0e\u7a7a\u5e8a\u63a5\u89e6\u65f6\u95f4\uff1b<\/li>\n<li>\u9884\u671f\u7a7f\u900f\u65f6\u95f4\uff1b<\/li>\n<li>\u6362\u70ad\u6216\u518d\u751f\u9891\u6b21\uff1b<\/li>\n<li>\u518d\u751f\u65b9\u5f0f\u53ca\u518d\u751f\u540e\u7684\u5bb9\u91cf\uff1b<\/li>\n<li>Bed temperature, pressure-drop, and outlet VOCs monitoring;<\/li>\n<li>\u9632\u706b\u4e0e\u6e29\u5ea6\u63a7\u5236\uff1b<\/li>\n<li>\u5e9f\u70ad\u8fd0\u8f93\u3001\u518d\u751f\u4e0e\u5904\u7f6e\u8981\u6c42\u3002<\/li>\n<\/ul>\n<p>\u8bbe\u8ba1\u4eba\u5458\u8fd8\u5e94\u533a\u5206\u9971\u548c\u5bb9\u91cf\u3001\u7a7f\u900f\u5bb9\u91cf\u4e0e\u5de5\u4f5c\u5bb9\u91cf\u3002<\/p>\n<p>Saturation capacity represents the maximum amount of contaminant the carbon can hold under specified equilibrium conditions.
