    摘要: A plant gas to be flared in the atmosphere is periodically sampled and analyzed as to its Btu content, a first comparison made of 1) the most recent of such analyses with 2) a predetermined steady state set point, a second comparison made of 3) an average of a plurality of such analyses including an historical minimum Btu content with 4) a predetermined dynamic set point, and fuel added to the plant gas based on the larger fuel requirement of these first and second comparisons.

    摘要: A multilayer film and a method of making the film are disclosed. In the method a multilayer film is post-oriented uniaxially in the machine direction resulting in a film that has a water vapor transmission rate of less than 2.5 g-mil/m2-day and an oxygen transmission rate of less than 1.5 cm2-mil/m2-day. The film of this invention is ideal for applications requiring low water vapor and oxygen transmission rates.
