一、天然氣脫硫設(shè)備的工作原理：
1、 Working principle of natural gas desulfurization equipment:
原料天然氣進(jìn)入脫硫設(shè)備界區(qū),先是經(jīng)過一個原料氣分離器,通過重力作用將原料氣中攜帶的少量游離水清理掉,然后氣體從脫硫塔頂部通過塔內(nèi)脫硫劑床層,氣體中的H2S被脫除。凈化天然氣從塔底出來,進(jìn)入凈化氣過濾分離器,分離出氣體中可能夾帶的脫硫劑粉塵,出凈化氣過濾分離器的天然氣直接匯入輸氣總管。至于再生操作,由于操作條件很難控制,且再利用成果不佳，故目前脫硫劑均一次性使用。
When the feed gas enters the battery limit of desulfurization equipment, it first passes through a feed gas separator to remove a small amount of free water carried in the feed gas by gravity, and then the gas passes through the desulfurizer bed in the tower from the top of the desulfurization tower, and the H2S in the gas is removed. The purified natural gas comes out from the tower bottom and enters the purified gas filter separator to separate the desulfurizer dust that may be entrained in the gas, and the natural gas from the purified gas filter separator directly flows into the gas transmission main pipe. As for the regeneration operation, since the operating conditions are difficult to control and the reuse results are poor, the desulfurizer is currently used once.
根據(jù)氣質(zhì)條件、處理量和場站規(guī)劃建設(shè)方案等具體情況，可選擇不同的干法脫硫工藝方案。當(dāng)前方案有原料氣分離器＋雙塔＋凈化氣過濾分離器。除此外還有雙塔＋凈化氣過濾分離器、原料氣分離器＋四塔＋凈化氣過濾分離器、四塔+凈化氣過濾分離器方案等等。
Different dry desulfurization process schemes can be selected according to the specific conditions such as gas quality conditions, treatment capacity and station planning and construction scheme. The current scheme includes feed gas separator + double tower + purified gas filter separator. In addition, there are schemes of double tower + purified gas filter separator, feed gas separator + four towers + purified gas filter separator, four towers + purified gas filter separator, etc.
二、天然氣脫硫設(shè)備技術(shù)特點(diǎn)：
2、 Technical features of natural gas desulfurization equipment:
（1）脫硫劑，具有硫容高、強(qiáng)度大等優(yōu)點(diǎn)，其實(shí)際硫容可達(dá)25%～30%（質(zhì)量分?jǐn)?shù)）;
(1) Desulfurizer has the advantages of high sulfur capacity and high strength, and its actual sulfur capacity can reach 25% ~ 30% (mass fraction);
（2）脫硫劑可在0.1～8.0MPa壓力范圍內(nèi)操作，且只脫除H，S不脫除CO2，凈化氣H，S含量可達(dá)一類天然氣的要求;
(2) The desulfurizer can be operated within the pressure range of 0.1 ~ 8.0MPa, and only h and s are removed without CO2. The content of H and s in purified gas can meet the requirements of class I natural gas;
（3）設(shè)備的流程和設(shè)備都簡單，操作方便，可實(shí)現(xiàn)無人值守;
(3) The process and equipment of the equipment are simple, easy to operate and unattended;
（4）設(shè)備投資和生產(chǎn)成本均較低，除裝料時需少量耗能外，在運(yùn)行條件下基本無能耗;
(4) The equipment investment and production cost are low. Except for a small amount of energy consumption during loading, there is basically no energy consumption under operating conditions;
（5）有廢渣處理問題，但廢渣對人、畜沒損害，對環(huán)境不構(gòu)成污染，對堿性土壤有一些改良作用;
(5) There is the problem of waste residue treatment, but the waste residue does not damage people and livestock, does not pollute the environment, and has some improvement effect on alkaline soil;
（6）使用固體脫硫劑的天然氣脫硫設(shè)備，潛硫量越佳范圍為H2S脫除量≤150kg/d，（按原料氣含硫量不同），節(jié)約了操作成本。
(6) For the natural gas desulfurization equipment using solid desulfurizer, the better the sulfur potential is, the H2S removal amount is ≤ 150kg / D (according to the sulfur content of feed gas), which saves the operation cost.
