甲醇及轻烃是天然气采输中的必须辅助材料及附属产品，均属于危化品，有毒，并由于其能带来可观的效益，导致管理难度大，由于种种原因导致甲醇、轻烃存在非法流失的可能，如何有效防其非法流失成为目前亟待要解决的重要问题。因此，本文对甲醇、轻烃管理中存在的问题进行详尽分析并提出有效对策，希望能对甲醇、轻烃的日常管理有所帮助。“,”methanol and light hydrocarbon are necessary auxiliary materials and ancillary products in natural gas production and transportation. They are dangerous chemicals and toxic. Because they can bring considerable benefits, it is difficult to manage them. Due to various reasons, methanol and light hydrocarbon may be illegally lost. How to effectively prevent their illegal loss has become an important problem to be solved. Therefore, this paper makes a detailed analysis of the problems existing in the management of methanol and light hydrocarbon, and puts forward effective countermeasures, hoping to be helpful to the daily management of methanol and light hydrocarbon.
