Reducing emissions of VOCs from low-pressure storage tanks

摘要: An apparatus and method for reducing or controlling VOC emissions from a low-pressure storage tank VOC-containing substance stored transported as liquid in the are provided. The include filter media operatively positioned between headspace atmosphere, wherein: (i) gaseous passes through to be vented atmosphere; (ii) comprises permeable substrate stripper VOC, wherein coats substrate; (iii) provides back pressure across atmosphere of less than 1 psig; (iv) condensate can drip flow under gravity into tank.
