硫的存在造成合成氨工艺中催化剂中毒，因此需将含硫天然气中的硫化氢、有机硫等硫化物脱除，使产品天然气的硫化氢和有机硫含量符合有关技术指标要求，满足生产需要。在天然气化工迅猛发展的今天，天然气脱硫方法也层出不穷。在传统一已醇胺湿法脱硫，氧化锌干法脱硫的基础上，出现了常温氧化铁脱硫，活性炭干法脱硫，分子筛脱硫，DDS生化湿法脱硫等新技术。

China mainly natural gas used in the production of nitrogen, followed by the production of methanol, formaldehyde, acetylene, methylene chloride, carbon tetrachloride, carbon disulfide, nitromethane, hydrocyanic acid and extraction of helium and carbon black. Since the 70s, has built more than natural gas and oil field associated gas as raw materials for large-scale ammonia plant, as well as a number of small and medium-sized ammonia plant, so that the national structure of the synthetic ammonia production of raw materials, natural gas share of about 30%; also be built at the same time A system of acetylene gas plant to manufacture Vinylon and vinyl acetate, acetylene gas used in the production of methanol.

中国天然气主要用于生产氮肥，其次是生产甲醇、甲醛、乙炔、二氯甲烷、四氯化碳、二硫化碳、硝基甲烷、氢氰酸和炭黑以及提取氦气。70年代以来，已兴建多座天然气和油田伴生气为原料的大型合成氨厂，以及一批中、小型合成氨厂，使全国合成氨生产原料结构中，天然气所占的比例约达到30％；同时还兴建了天然气制乙炔工厂，以制造维尼纶和醋酸乙烯酯，乙炔尾气用于生产甲醇。

According to the researches, the natural gas in this area is mainly controlled by structures and sedimentation, faults play a very important role in the natural gas's movement, the high spot areas of paleostructures are the advantageous gathering places of natural gas today; the sedimentary facies of the area is mainly the delta front subfacies, and the thickness of sand bed is relatively thin, the fuzzy diagnosis of natural gas indicates that the gas of this oil layer is distributed dispersively.

研究认为，本地区的天然气分布主要受构造和沉积控制，断层对天然气的运移起到至关重要的作用，古构造的高点地区是现今天然气的有利聚集区；本区沉积相主要为三角洲前缘亚相，砂体厚度相对较小，模糊识别天然气预测显示该油层天然气呈分散状分布；但总体看，由于本区天然气埋藏很浅，容易开发，且天然气预测分布面积之总和具一定规模，因此有较好的发展前景。

Amid the murk of contrary claims, some clear points stand out. First, Ukraine's gas stores matter, because when it draws on them to meet domestic demand it disrupts flows in the pipes used to ship gas from Russia to Europe. Second, a lucky few make vast sums from Russia's trade in gas with Ukraine, much of which flows through unmetered pipes in quantities and at prices that are secret. Third, even a loan to Ukraine to buy winter gas might not avert a crunch.

拨开双方对立言论的迷雾，还是可以找出确切无疑的几点：首先，乌克兰天然气公司脱不了干系，因为在满足国内需求的要求下，他们扰乱了俄罗斯-欧盟天然气管道内天然气的流向；其次，有少数幸运的人在俄乌天然气交易中大赚了一笔，他们通过数量不明的管道输送天然气，卖价也是一个秘密；再次，给乌克兰提供购买天然气贷款也许同样无法消除危机。

Including high temperature for the pyrolysis of natural gas to produce carbon black and acetylene; steam reforming of natural gas or partial oxidation of natural gas, synthetic gas can be obtained; natural gas through chlorination, sulfide, nitrification, ammoniated oxide, oxidation can be obtained A N all kinds of derivatives; in the wet gas ethane, propane, butane and natural gas liquid condensate, and so on, the steam cracker or pyrolysis to produce ethylene, propylene and butadiene; dehydrogenation of butane oxidation or produce small Diene or acetic acid, methyl ethyl ketone, and maleic anhydride, and so on.

However, in this field of study in China there still exists five points of issues as follows:(1) the forecast of natural gas hydrate resource at the sea is exaggerated;(2) studies on hydrate reservoiring dynamics, reservoiring system, and especially the hydrocarbon source are not enough as well;(3) research on physical stratigraphy of hydrate sedimentary reservoir rocks is still blank;(4) the relationships among the BSR in the seismic profile, blind zone of amplitude, and sedimentary reservoir are still unknown;(5) the exploration technical studies are not complete and systematic yet.

但是，中国海域天然气水合物的勘探研究还存在5个方面的主要问题：海域天然气水合物资源量预测过大；对天然气水合物成藏动力学、成藏体系研究不够，尤其是对烃源研究不够；中国在天然气水合物沉积层岩石物理方面的研究几乎还是空白；对地震剖面上的BSR、振幅空白带与天然气水合物沉积层的关系仍然不是十分清楚；中国目前的天然气水合物勘探技术研究还不够深入、不够系统。
