Mathematical modelling and verifying tests with a small sieve-plate column were conducted for simulating methanol column, azeotrope column and water-removal column which were to be used for removal of water from higher alcohols with cyclohexane as a azeotrope former. 对低碳燃料醇环己烷共沸蒸馏脱水三塔(甲醇塔、共沸塔和脱水塔)流程中的各塔进行了数模计算,并用小型筛板塔进行验证。
